The CMOS inverter integrated circuitry (non-logical gate) Additional Metallic Semiconductor Oxide (CMOS), also known as complementary-symmetrical metal-oxide-semiconductor (COS-MOS), is a type of metal-oxide-semiconductor field-field transistor (MOSFET) manufacturing process that uses additional and symmetrical p-type pairs. CMOS technology is used to build integrated circuit chips (IC), including microprocessors, microcontrollers, memory chips (including CMOS BIOS) and other digital logic schemes. CMOS technology is also used for analog circuits such as image sensors (CMOS sensors), data converters, RFS circuits (RFOS) and highly integrated transceivers for many types of communication. Mohamed M. Atallah and Dovon Kang invented MOSFET at Bell Labs in 1959 and then demonstrated the manufacturing processes of PMOS (p-type MOS) and NMOS (n-type MOS) in 1960. These processes were later combined and adapted into an additional PROCESS by Chi-Tan Sahom and Frank Wanlass at Fairchild Semiconductor in 1963. RCA commercialized the technology with the brand name COS-MOS in the late 1960s, forcing other manufacturers to look for a different name, which leads to the fact that by the early 1970s CMOS became the standard name of the technology. CMOS eventually overtook NMOS as the dominant process of making MOSFET chips for very large-scale integration (VLSI) chips in the 1980s, as well as replacing the earlier Transistor- Transistor Logic (TTL). Since then, CMOS has remained the standard manufacturing process for MOSFET semiconductor devices in VLSI chips. Compared to 2011, 99% of IC chips, including most digital, analog and mixed IC signaling, are manufactured using CMOS technology. Two important characteristics of CMOS devices are high noise immunity and low static energy consumption. Because one MOSFET transistor is always off, the series combination draws significant power only for a moment while switching between states and off. Consequently, CMOS devices do not produce as much heat waste as other forms of logic, such as NMOS logic or logic (TTL), which usually have some constant current even in a non-changing state. These Are These allow CMOS to integrate high density of logical functions on the chip. It is for this reason that CMOS has become the most widely used technology to be introduced into VLSI chips. The phrase metal-oxide-semiconductor is a reference to the physical structure of the MO-effect transistors, having a metal electrode gate placed on top of the oxide insulator, which in turn is on top of a semiconductor material. Aluminium was once used, but now the polysilicon material. Other metal gates have made a comeback with the advent of high-th dielectric materials in the CMOS process, as announced by IBM and Intel for a 45 nanometer node and smaller size. Technical Details Additional information: CMOS semiconductor manufacturing processes relate to both a particular style of digital circuit design and the family of processes used to implement this scheme on integrated circuits (chips). The CMOS scheme dissipates less energy than logical families with resistive loads. As this advantage has increased and become more important, the processes and variants of CMOS have come to dominate, thus, the vast majority of modern production of integrated circuits is on the processes of CMOS. THE CMOS logic consumes more than 7 times less energy than NMOS logic, and about 100,000 times less energy than bipolar transistor-transistor logic (TTL). THE CMOS schemes use a combination of p-type transistor and n-type metal-oxide-semiconductor effect (MOSFETs) to implement logical gates and other digital circuits. While the CMOS logic can be implemented with discrete demonstration devices, CMOS commercial products are integrated circuits consisting of up to billions of transistors of both types, on a rectangular piece of silicon from 10 to 400 mm2. CMOS always uses all MOSFETs mode enhancements (in other words, the zero gate voltage to the source is turned off by the transistor). History Additional information: MOSFET and Transistor density MOSFET (metal-oxide semiconductor field effect transistor, or MOS transistor) was invented by Mohamed M. Atallah and Davon Kang at Bell Labs in 1959. Initially, there were two types of MOSFET manufacturing processes: PMOS (p-type MOS) and NMOS (n-type MOS). Both types were developed by Atalla and Kahng when they originally invented MOSFET, manufacturing both PMOS and NMOS devices with 20 microns and then a length of 10 microns of gate in 1960. While MOSFET was initially overlooked and ignored by Bell Labs in favor of bipolar transistors, the invention of MOSFET generated considerable interest in Fairchild Semiconductor. Based on Atallah's work, Chih-Tan Sah introduced MOS Fairchild technology with his mos-controlled tetrod, fabricated in late 1960. A new type of MOSFET logic has been developed that combines PMOS and NMOS, called Additional MOS (CMOS), Chi-Tan Sahom and Frank Wanlass in Fairchild. In February, February they published the invention in a research paper. Wanlass later filed a U.S. patent for 3,356,858 on the CMOS scheme in June 1963, and it was issued in 1967. Both research and patents established the manufacture of CMOS devices based on the thermal oxidation of a silicon substrate to produce a layer of silicon dioxide located between the runoff contact and the original contact. CMOS was commercialized by RCA in the late 1960s. RCA adopted CMOS for Integrated Circuit Design (ICs), developing CMOS circuits for an Air Force computer in 1965 and then a 288-bit CMOS SRAM memory chip in 1968. RCA also used CMOS for its integrated 4000 series circuits in 1968, starting with a 20 microcontivity production process before gradually scaling up to 10 micrometers of the process over the next few years. CMOS technology was initially overlooked by the U.S. semiconductor industry in favor of NMOS, which was more powerful at the time. However, CMOS was quickly adopted and pushed forward by Japanese semiconductor manufacturers due to its low energy consumption, which led to the growth of the Japanese semiconductor industry. In 1969, Toshiba developed C2MOS (Clocked CMOS), a chain technology with lower power consumption and faster speeds than conventional CMOS. Toshiba used its C2MOS technology to develop a large-scale integration (LSI) chip for Sharp's Elsi Mini LED pocket calculator, developed in 1971 and released in 1972. Suva Seikosha (now Seiko Epson) began developing the CMOS IC chip for Seiko quartz watches in 1969, and in 1971 began mass production with the launch of the Seiko Analog zuartz 38S'W. The first mass consumer electronic product of CMOS was the Hamilton Pulsar Wrist Computer digital watch, released in 1970. Because of its low energy consumption, the logic of CMOS has been widely used for calculators and watches since the 1970s. By the late 1970s, NMOS microprocessors had overtaken PMOS processors. CMOS microprocessors were introduced in 1975, with Intersil 6100, and RCA CDP 1801. However, CMOS processors did not become dominant until the 1980s. thus, NMOS was more widely used for computers in the 1970s. The Intel 2147 (4 kb SRAM) HMOS (1976) memory chip had access time of 55/70 ns. In 1978, the Hitachi research team, led by Toshiaki Masuhara, presented the Hi-CMOS process with a HM6147 (4 kb SRAM) memory chip made with a 3 micrometer process. The Hitachi HM6147 Chip was able to match performance (55/70 ns access) 2147 HMOS chip, while HM6147 also consumed significantly less energy (15 mA) than 2147 (110 mA). With comparable performance and much less energy consumption, the CMOS process with two wells eventually overtook NMOS as the most common semiconductor manufacturing process for computers in the 1980s. NASA's Galileo spacecraft, sent into Jupiter orbit in 1989, used the RCA 1802 CMOS microprocessor due to low energy consumption. In 1983, intel introduced the production process for 1.5 microconducting CMOS semiconductor devices. In the mid-1980s, IBM's Bijan Davari developed high-performance, low-voltage, deep-submi micron CMOS technology that allowed faster computers to develop as well as laptops and battery-powered portable electronics. In 1988, Davari led the IBM team, which demonstrated the high performance of the 250 nanometer CMOS process. In 1987, Fujitsu commercialized the CMOS process with 700 nm, and in 1989 Hitachi, Mitsubishi Electric, NEC and Toshiba commercialized 500 nm of CMOS. In 1993, Sony commercialized the CMOS process with 350 nm, while Hitachi and NEC commercialized 250 nm cm of CMOS. Hitachi introduced the 160 nm CMOS process in 1995, then Mitsubishi introduced 150 nm CMOS in 1996, and then Samsung Electronics introduced 140 Nm in 1999. In 2000, Gurtei Singh Sandhu and Trung T. Doan of Micron Technology invented the atomic deposition layers of high-electric films, leading to the development of a cost-effective 90-nm CMOS process. Toshiba and Sony developed the CMOS 65 nm process in 2002, and then TSMC began developing 45 nm CMOS Logic in 2004. The development of the Gurtej Singh Sandhu dual template at Micron Technology led to the development of the 30 nm CMOS class in the 2000s. As of 2010, the processors with the best performance per watt each year have been the static logic of CMOS since 1976. Planar CMOS is still the most common form of semiconductor manufacturing from 2019, but is gradually being replaced by non-planetary FinFET technology, which is capable of producing semiconductor nodes of less than 20 nm. THE CMOS inversion circuits are designed in such a way that all P-type metal-oxide-semiconductor (PMOS) transitors must have either input from the voltage source or from another PMOS transistor. Similarly, all NMOS transistors must have either input from the ground or from another NMOS transistor. The composition of the PMOS transistor creates a low resistance between its source and drainage contacts when applying low gate voltage and high resistance when applying high-voltage gates. On the other hand, the composition of the NMOS transistor creates a high resistance between the source and the runoff low-voltage gates and Resistance when applying a high voltage gate. CMOS performs the current abbreviation, complementing each nMOSFET with pMOSFET and connecting both gates and both drains together. High voltage at the gate will cause nMOSFET to hold and pMOSFET not to hold, while the low voltage on the gate causes the reverse. This location significantly reduces energy consumption and heat production. However, while switching time, both MOSFETs hold briefly as the voltage of the gate moves from one state to another. This causes a short-term spike in energy consumption and becomes a serious problem at high frequencies. Static inverter CMOS. Vdd and Vss stand for runoff and source respectively. A nearby image shows what happens when the input is connected to both the PMOS transistor (top of the chart) and the NMOS transistor (bottom of the chart). When the voltage of the input signal A is low, the NMOS transistor channel is in a state of high resistance. This limits the current that can flow from th to ground. The PMOS transistor channel is in a low-resistance state and much more current can flow from delivery to output. Since the resistance between the feed voltage and q is low, the voltage drop between the feed voltage and q due to the current drawn from q is small. Thus, the output registers a high voltage. On the other hand, when the voltage of entering A is high, the PMOS transistor is in a state of off (high resistance), so it will limit the current arising from the positive offer to exit, while the NMOS transistor is in the on (low resistance) state, allowing the exit from the drain to the ground. Due to the low resistance between the ground and the ground, the drop in voltage due to the current drawn into the location above the ground is small. This low drop leads to a low voltage registration. In short, the outputs of PMOS and NMOS transistors complement each other, which is high when the input level is low, and the output is low at high entry. Because of this behavior of input and output, the output of the CMOS circuit is a reverse input. Power Pins See. Also: IC power pin pin pins for CMOS are called VDD and VSS, or VCC and Ground (GND) depending on the manufacturer. VDD and VSS are transfers from conventional MOS schemes and stand for runoff and supply sources. They do not apply directly to CMOS, as both sources of supply are indeed sources of supply. VCC and Ground are carriers from TTL logic, and the item has been retained with the introduction of the CMOS 54C/74C line. The CMOS scheme is created to allow the path to always exist from the exit of either a power source or land. To achieve this goal, a set of all paths to tensions should set all paths to the ground. This can be easily achieved by defining one from the perspective of NOT the other. Due to the logic of De Morgan's laws, PMOS transistors have the corresponding NMOS transistors in the series in parallel, while PMOS transistors in the series have appropriate NMOS transistors in parallel. The logic of nand gate in the logic of CMOS More complex logic functions such as those involving and or gates require manipulating the path between the gates to present logic. When the path consists of two transistors in a series, both transistors must have low resistance to the corresponding power voltage by modeling AND. When the path consists of two transistors in parallel, one or both transistors must have low stability to connect power voltage to the exit by modeling OR. On the right is a nanD gate chain diagram in the CMOS logic. If both inputS A and B are high, then as NMOS transistors (bottom half of the chart) will not hold, none of the PMOS transistors (top half) will conduct, and the conductive path will be set between exit and Vss (land), resulting in a low output. If both A and B inputs are low, neither of the NMOS transistors will conduct, while both PMOS transistors will conduct, setting the conductive path between the exit and the Vdd (the source of voltage), resulting in a high output. If one of the A or B inputs is low, one of the NMOS transistors will not conduct, one of the PMOS transistors will, and the conductive path will be set between the exit and the Vdd (the source of the voltage), resulting in a high output. Because the only configuration of the two input data that leads to a low output is when both are high, this scheme implements the NAND (NOT AND) logic gate. The advantage of CMOS compared to NMOS logic is that transitions with low and high and low output are fast, as pull-up transistors (PMOS) have low resistance when turned on, as opposed to load resistors in NMOS logic. In addition, the output signal pumps full voltage between low and high rails. This stronger, more almost symmetrical response also makes CMOS more resistant to noise. See Logical Efforts for the METHOD of calculating latency in the CMOS chain. Example: NAND IN the physical layout of the NanD Physical Layout. Larger areas of N-type diffusion and P-type diffusion are part of transistors. Two small regions on the left are taps to prevent latch. Simplified process of manufacturing CMOS inverter on a p-type substrate in a semiconductor micro-fabrication. In Step 1, layers of silicon dioxide are formed initially through thermal oxidation Note: The gate, source and drainage contacts are usually not in the same plane in real devices, and the diagram does not scale. This example shows the NAND logical device as physical representation as it would be manufactured. Made. The physical perspective of the layout is a bird's look from a stack of layers. The scheme is built on a substrate such as P. Polysilicon, diffusion, and n-well called base layers and is actually inserted into the P-type substrate trenches. (See steps 1 to 6 on the process diagram below right) Contacts penetrate into the insulation layer between the base layers and the first layer of metal (metal1), making the connection. The entrances to NAND (illustrated in green) are polysilicon. Transistors (devices) are formed by crossing polysilicon and diffusion; N diffusion for device N and P diffusion for device P (illustrated in salmon and yellow coloring respectively). The output (outside) is connected to metal (illustrated in cyanide). The connections between metal and polysilicon or diffusion are made through contacts (illustrated as black squares). The physical layout is consistent with the NAND logic in the previous example. The N device is made on a type P substrate, while the P device is manufactured in n-well. The P-type tap substrate is connected to VSS, and the N-type n-well crane is connected to the VDD to prevent latch. Cross-section of two transistors at the CMOS gate, in the N-well CMOS powering process: switching and leaking CMOS logic dissipates less energy than NMOS logical circuits, because CMOS dissipates power only when switching (dynamic power). In a typical ASIC in today's 90 nanometer process, output switching can take 120 picoseconds and occurs every ten nanoseconds. The logic of NMOS dissipates energy whenever the transistor is on, because there is a current path from Vdd to Vss through the load resistor and n-type network. The static CMOS gates are very energy efficient because they dissipate almost zero power when simple. Previously, the energy consumption of CMOS devices was not a major problem when designing chips. Factors such as speed and area dominated the design parameters. As CMOS technology has moved under sub-micron levels the consumption of power into the chip block area has risen by multiplying the software. Widely classified, power scattering in CMOS circuits occurs because of two static and dynamic components: Static scattering of both NMOS and PMOS transistors have a gate-source of threshold voltage below which the current (called sub threshold current) through the device falls exponentially. Historically, CMOS designs have worked on power voltage much more than their voltage thresholds (Vdd may have been 5 V, and Vth for NMOS and PMOS may have been 700 mW). The particular type of transistor used in some CMOS circuits is a native transistor with almost zero threshold voltage. SiO2 is a good insulator, but at very small levels of thickness electrons can tunnel through very subtle insulation; falls exponentially with oxide oxide The tunnel current becomes very important for transistors below 130 nm of technology with gate oxides 20 or thinner. Small reverse leaks are formed as a result of reverse displacement between diffusion regions and wells (e.g., p-type diffusion against n-well), wells and substrate (e.g. n-well vs. p-substrate). In the modern process, the leakage of the diode is very small compared to the sub-weather and tunnel currents, so they can be neglected during power calculations. If the odds do not match, there may be different tocs of PMOS and NMOS; this can lead to an imbalance and thus the wrong course causes CMOS to heat up and dissipate the energy unnecessarily. In addition, recent studies have shown that power leakage decreases due to the effects of aging as a compromise for devices to become slower. Dynamic scattering Charging and unloading load capacity of the CMOS chain dissipate the power by charging different load tanks (mainly gate and condensate wires, but also runoff and some sources of capacity) whenever they switch. In one full loop of CMOS logic, the current flows from VDD into the payload capacity to charge it, and then flows from the charged capacity (CL) to the ground during discharge. Thus, during one full cycle of charge/discharge, a total of hlVD is transferred from VDD to the ground. Multiply by the frequency of switching to payload capacity to get the current used, and multiply by the average voltage again to get the characteristic power switching dissipated on the CMOS device: P 0.5 C v 2 f displaystyle P 0.5CV {2}f. Because most gates do not work/switch on each hour cycle, they are often accompanied by a factor α alpha display called an activity factor. Now the dynamic power scattering can be rewritten as P and α C V 2 f (Pe Alpha {2}f display). The watch in the system has an activity factor α 1, as it rises and falls each cycle. Most of the data has an activity rate of 0.1. If the correct payload is assessed per node along with its activity factor, the dynamic power scattering in that node can be effectively calculated. Since there is a finrangy rise/fall time for both pMOS and nMOS, during the transition, for example, from off to the farthest, both transistors will continue for a short period of time, during which the current will find its way directly from VDD to the ground, thus creating a short circuit of the current. The scattering of short circuit power increases with the time transistors rise and fall. The additional form of energy consumption became significant in the 1990s, when the wires on the chip became narrower and long wires became more resistor. The CMOS gate at the end of these resistor wires sees entrance transitions. In the middle of these transitions, the logical NMOS and PMOS networks are partially conductive, and current flows are directly from VDD to VSS. Thus, the power of power called a scrap of power. The meticulous design, which avoids poorly controlled long, skinny wires, washes this effect, but the scrap power can be an essential part of CMOS's dynamic power. To speed up the design, manufacturers have switched to designs that have lower voltage thresholds, but because of this the modern NMOS transistor with Vth 200 mV has a significant flow leak current. Designs (such as desktop processors) that include a huge number of circuits that don't actively switch still consume energy due to this current leak. Energy leakage is a significant part of the total power consumed by such structures. Multi-stage CMOS (MTCMOS), now available from foundries, is one approach to managing energy leakage. With MTCMOS, high Vth transistors are used when the switching speed is not critical, while low Vth transistors are used in speed-sensitive pathways. Further technological advances that use even thinner gate dielectrics have an additional leak component due to the current tunnels through extremely thin dielectric gates. Using a high and dielectric instead of silicon dioxide, which is a conventional dielectric gate allows for similar performance to the device, but with a thicker insulator gate, thus avoiding this current. Reducing leakage power using new materials and system designs is critical to maintaining the scalability of CMOS. Protection from the introduction of parasitic transistors inherent in the CMOS structure can be turned on by input signals outside the normal range of work, such as electrostatic discharges or linear reflections. As a result, the latch can damage or destroy the CMOS device. Clip diodes are included in CMOS circuits to combat these signals. The lists of the manufacturers' data indicate the maximum allowable current that can pass through diodes. Analog CMOS Additional information: CMOS amplifier and mixed signal integrated circuit, in addition to digital applications, CMOS technology is also used in analog applications. For example, there are CMOS operating IR amplifiers on the market. The transmission gate can be used as analog multiplexers instead of signal repeaters. CMOS technology is also widely used for RF circuits in any case on microwave frequencies, in mixed signal (similar digital) applications. (quote is needed) RF CMOS: RF CMOS RF CMOS refers to RF (radio- frequency circuits) that are based on the cmOS integrated mixed signal scheme technology. They are widely used in wireless telecommunications technologies. RF CMOS was developed by Asad Abidi while working in California in the late 1980s. This changed the way in which RF circuits were developed, leading to the replacement of discrete bipolar transistors with CMOS integrated circuits in radio transmissions. This has enabled sophisticated, inexpensive and portable end-user terminals, and has spawned small, inexpensive, low-power and portable devices for a wide spectrum of spectrum communication systems. This allowed at any time, anywhere and helped to achieve the wireless revolution that led to the rapid growth of the wireless industry. Basic processors and radio transmissions in all modern wireless network devices and mobile phones are mass-produced using RFOS devices. RF CMOS schemes are widely used to transmit and receive wireless signals in various applications, such as satellite technologies (such as GPS), Bluetooth, Wi-Fi, near-field communication (NFC), mobile networks (such as 3G and 4G), terrestrial broadcasting and automotive radar applications, among other applications. Examples of commercial RF CMOS chips include The Intel DECT Wireless Phone and 802.11 (Wi-Fi) chips created by Atheros and other companies. Commercial RF CMOS products are also used for Bluetooth and Wireless LAN (WLAN) networks. RF CMOS is also used in radio broadcasts for wireless standards such as GSM, Wi-Fi and Bluetooth, mobile transceivers such as 3G, and remote devices in wireless touch networks (WSN). RF CMOS technology is critical to modern wireless communications, including wireless networks and mobile communications devices. One of the companies that commercialized RF CMOS technology was Infineon. Its bulk CMOS RF switches sell more than 1 billion units a year, reaching a cumulative 5 billion units, as the 2018 update. Temperature range Conventional CMOS devices run in the range of -55 to 125 degrees Celsius. As early as August 2008, there were theoretical signs that silicon CMOS would run up to -233 degrees Celsius (40 K). Since then, a running temperature of about 40K has been achieved using AMD Phenom II acceleration processors with a combination of liquid nitrogen and liquid helium cooling. MOS Ultra small single-electronic transistors (L 20 nm, W and 20 nm) MOSFETs reach the single-electronic limit when working at cryogenic temperature ranging from -269 C (4 K) to about -258 C (15 K). The transistor displays the blockade of the coulomb due to the progressive charging of electrons one by one. The number of electrons limited in the channel is determined by the voltage of the gate, starting with zero electrons, and can be set up to one or more.

(April 2017) (Learn how and when to delete this message template) Part of the series on mobile phone Generation Mobile Telecommunications 0G 2G 2.5G 2.75G 3G 3.5G 3.75G 3.75G 3. 9G/3.95G 4G 4G/4.5G 4.5G/4.9G 5G 6G vte 3G (short for third generation) is the third generation of wireless mobile telecommunications technology. This is an update for 2.5G and 2.5G GPRS networks, for faster data transmission. It is based on a set of standards used by the International Telecommunication Union (IMT-2000) for mobile devices and mobile and network services that meet the specifications of the International Mobile Union-2000 (IMT-2000). 3G is used in wireless voice telephony, mobile Internet access, fixed wireless Internet access, video calls and mobile television. 3G telecommunications support services, which provide at least 144 kbps of information, also provide multi- Mbit/s mobile broadband access to smartphones and mobile modems on laptops. This ensures that it can be applied to voice telephony, mobile Internet access, fixed wireless Internet access, video calls and and and Television technology. A new generation of cellular standards has been introduced in about every tenth year since the introduction of 1G systems in 1979 and in the early to mid-1980s. Each generation is characterized by new frequency ranges, higher data transmission rates and incompatible with reverse movement technology. The first commercial 3G networks were commissioned in mid-2001. A review of several telecommunications companies' mobile Internet wireless services market, like 3G, indicating that the advertised service is provided via a 3G wireless network. To meet IMT-2000 standards, However, many services advertised as 3G provide higher speeds than the minimum technical requirements for 3G service. The following standards are usually branded 3G: umTS (Universal Mobile Telecommunications System), first proposed in 2001, standardized 3GPP, is used mainly in Europe, Japan, China (however with other radio interface) and other regions, mainly GSM (Global Systems for Mobile Devices) 2G System Infrastructure. Cell phones are usually UMTS and GSM hybrids. There are several radio interfaces that share the same infrastructure: the original and most common radio interface is called W-CDMA (Wideband Code Division Multiple Access). The TD-SCDMA radio interface was commercialized in 2009 and is only offered in China. The latest release of UMTS, HSPA, can provide peak data transmission rates of up to 56 Mbps in downlink in theory (28 Mbit/s in existing services) and 22 Mbit/s in uplink. The CDMA2000 system, first proposed in 2002, standardized 3GPP2, is used, especially in North America and Korea, sharing infrastructure with is-95 2G. Cell phones are usually CDMA2000 and IS-95 hybrids. The latest release of EVDO Rev B offers peak rates of 14.7 Mbps downstream. The aforementioned systems and radio interfaces are based on the radio transmission technology of the spectrum of distribution. While the GSM EDGE (2.9G), DECT wireless phones and Mobile WiMAX standards also formally meet IMT-2000 requirements and are approved by ITU as 3G standards, they are generally not 3G branded and are based on completely different technologies. The following common standards meet the IMT2000/3G standard: EDGE, revision by 3GPP of old transmission based on 2G GSM, using the same switching nodes, base stations and frequencies as GPRS, but new base stations and cell phone RF schemes. It is based on three times more efficient than 8PSK 8PSK scheme as a supplement to the original GMSK modulation scheme. EDGE is still widely used because of its ease of upgrade from existing 2G GSM infrastructure and cell phones. EDGE, combined with GPRS 2.5G technology called EGPRS, allows peak data transmission in 200 kbps, like the original versions of the UMTS WCDMA, and thus formally meets the IMT2000 requirements for 3G systems. EDGE shows slightly better system spectral efficiency than the original UMTS and CDMA2000 systems, but it is difficult to achieve much higher peak data speeds due to the limited spectral bandwidth of the GSM 200 kHz, and this is thus a dead end. EDGE was also mode in the SYSTEM IS-136 TDMA, today stopped. Evolved EDGE, the latest edition, has peaks of 1 Mbps downstream and 400 kbps upstream, but is not used in commercial companies. A universal mobile telecommunications system created and revised by 3GPP. The family represents 1000 m. in terms of coding methods and equipment, although some GSM sites can be upgraded for UMTS/W-CDMA broadcasting. W-CDMA is the most common deployment typically used at 2100 MHz. Some others use ranges of 850, 900 and 1900 MHz. HSPA is a combination of multiple updates to the original W-CDMA standard and offers speeds of 14.4 Mbps down and 5.76 Mbps up. HSPA is compatible with feedback with and uses the same frequencies as W-CDMA. HSPA, a further revision and update of the HSPA, can provide theoretical peak data speeds of up to 168 Mbps in downlink and 22 Mbit/s in uplink, using a combination of improved air interface as well as multi-carrier HSPA and MIMO. Technically though, MIMO and DC-HSPA can be used without I improving the HSPA' CDMA2000 system, or IS-2000, including CDMA2000 1x and CDMA2000 High Rate Packet Data (or EVDO), standardized 3GPP2 (different from 3GPP), evolving from the original IS-95 CDMA system, is used, especially in North America, China, India, Pakistan, Japan, Korea, Southeast Asia, Europe and Africa. CDMA2000 1x Rev. E has an increased voice capacity (over three times) compared to the Rev. 0 EVDO Rev. B offers downstream peak rates of 14.7 Mbps while Rev. C expands existing and new terminals to the user experience. Although DECT wireless phones and WiMAX mobile standards also formally meet the IMT-2000 requirements, they are not usually considered due to their rarity and unsuitability to use with mobile phones. In 1992, 3G (UMTS and CDMA2000) 3G systems (UMTS and CDMA2000) began researching and developing. In 1999, ITU approved five IMT-2000 as part of the ITU-R M.1457 Recommendation; WiMAX was added in 2007. There are evolutionary standards (EDGE and CDMA) that are backward-compatible extensions to pre-existing 2G 2G and revolutionary standards that require ever-new network hardware and frequency distributions. Cell phones use UMTS in conjunction with 2G GSM standards and bandwidth, but do not support EDGE. The last group is the UMTS family, which consists of standards developed for IMT-2000, as well as independently developed DECT and WiMAX standards, which were included because they met the definition of IMT-2000. While EDGE performs 3G specifications, most GSM/UMTS phones report EDGE (2.75G) and UMTS (3G) functionality. History 3G technology is the result of research and development carried out by the International Telecommunication Union (ITU) in the early 1980s. The specifications were available to the public under the name IMT-2000. The range of communications from 400 MHz to 3GHz was allocated to 3G. Both the government and communications companies approved the 3G standard. It was first available in May 2001 as a pre-release (test) of W-CDMA technology. The first commercial launch of 3G was also NTT DoCoMo in Japan on October 1, 2001, although initially it was somewhat limited in scope; The wider availability of the system has been delayed because of apparent concerns about its reliability. The first European pre-anchor network was the UMTS network on the Isle of Man from Manx Telecom, the operator then owned by British Telecom, and the first commercial network (also UMTS founded by W-CDMA) in Europe was opened for Telenor business in December 2001 without commercial phones and thus without paid customers. The first network to become a commercial company was SK Telecom in Korea using CDMA-based 1xEV-DO technology in January 2002. By May 2002, the second South Korean 3G network was CT on EV-DO and thus the South Koreans were the first to see competition among 3G operators. The second operator of the 3G network in the U.S. Verizon Wireless in July 2002 is also on CDMA2000 1x EV-DO. Att Mobility was also the real 3G UMTS network, which completed the upgrade of the 3G network to HSUPA. The first commercial 3G network in the UK was launched by Hutchison Telecom, which was originally behind Orange S.A. In 2003, the company announced the first commercial network of third generation mobile phones or 3G in the UK. The first pre-regional demonstration network in the southern hemisphere was built in Adelaide, southern Australia, by the m.Net Corporation in February 2002 using UMTS at 2100 MHz. It was a demonstration network of the 2002 World IT Congress. 3G's first commercial network launched launched Telecommunications under the brand Three or 3 in June 2003. In India, on December 11, 2008, the first 3G mobile and Internet services were launched by the state-owned Mahanagar Telecom Nigam Limited (MTNL) in the cities of Delhi and Mumbai, which focused only on megacities. After MTNL, another state-owned company, Bharat Sanchar Nigam Limited (BSNL), began deploying 3G networks across the country. Emtel has launched the first 3G network in Africa. Adoption of Japan was one of the first countries to adopt 3G, which was caused by the distribution of the 3G spectrum, which in Japan was awarded at no particular cost. The frequency spectrum has been allocated in the U.S. and Europe through auctions, which requires huge initial investment for any company wishing to provide 3G services. Nepal Telecom first hosted the 3G Service in South Asia. However, its 3G was relatively slow to be adopted in Nepal. In some cases, 3G networks do not use the same radio frequencies as 2G, so mobile operators need to create brand new networks and license entirely new frequencies, especially to achieve high data speeds. Delays in other countries were related to the cost of upgrading transmission equipment, especially for UMTS, whose deployment required the replacement of most broadcast towers. Because of these problems and deployment difficulties, many carriers have been unable or delayed the acquisition of these upgraded capabilities. According to the Global Association of Mobile Device Suppliers (GSA), 190 3G and 154 HSDPA networks operated in 40 countries in December 2007. In Asia, Europe, Canada and the United States, telecommunications companies use W- CDMA technology, supported by about 100 3G mobile terminal projects. Licensing fees in some European countries were particularly high, backed up by government auctions of a limited number of licenses and closed auctions, and initial excitement about the potential of 3G. This led to a telecommunications accident that occurred at the same time as similar accidents in fiber optic and dot.com areas. The 3G standard may be well known due to the massive expansion of the mobile market after 2G and the advances of the consumer mobile phone. A particularly notable event during this time is a smartphone (e.g. iPhone and Android family), combining the capabilities of the PDA with a mobile phone, which leads to a wide demand for mobile Internet communication. 3G has also introduced the term mobile broadband because its speed and capabilities make it a viable alternative browsing the Web, and USB Modems connecting to networks are becoming more common. Infiltration by June 2007, 200 million 3G subscribers were connected of which 10 million were in Nepal and 8.2 million in India. This 200-millionth share is only 6.7% of the 3 billion mobile phone subscriptions worldwide. (When counting CDMA2000 1x RTT customers-max bitrate 72% of 200kbit/s, which determines the 3G-total size of almost 3G subscriber base was 475 million as of June 2007, which accounted for 15.8% of all subscribers worldwide.) In countries where 3G was launched first - Japan and Korea - penetration of 3G is more than 70%. In Europe, the leading country for 3G penetration is Italy, a third of whose subscribers migrated to 3G. Other leading countries that use 3G include Nepal, the UK, Austria, Australia and Singapore at the migration level of 32%. ITU estimates that as of the fourth quarter of 2012, there were 2,096 million active mobile broadband subscribers out of 6,835 million subscribers, just over 30%. About half of mobile broadband subscribers for subscribers in developed countries, 934 million out of 1600 million in total, and more than 50%. Note, however, that there is a difference between a phone with mobile broadband and a smartphone with a large display and so on, Although according to ITU and informatandm.com the U.S. has 321 million mobile subscriptions, including 256 million that are 3G or 4G, which is as 80% of the subscriber base and 80% of the U.S. population, according to ComScore only a year earlier in the fourth quarter of 2011 only about 42% of people surveyed in the U.S. reported that they owned a smartphone. In Japan, 3G penetration was similar at around 81%, but smartphone ownership was down about 17%. China had 486.5 million 3G subscribers in June 2014, with a population of 1,385,566,537 (UN 2013 estimate). Decline and decommissioning Since the ever-increasing introduction of 4G, the use of 3G has been in decline. Several operators around the world are already or are in the process of closing their 3G networks. In several locations, 3G is now closed while its old predecessor 2G is being kept in operation - Vodafone Europe does so, citing the fact that 2G is a useful low power retreat. In the U.S., Verizon plans to close its 3G services by the end of 2020, while T-Mobile plans to do so in January 2021, and ATT plans to do so by 2022. It is estimated that there are nearly 8,000 patents declared necessary (FRAND) related to the 483 technical specifications that form the 3GPP and 3GPP2 standards. Twelve companies in 2004 made 90% of patents (Kvalcomm, Eriksson, Nokia, Motorola, Philips, NTT DoCoMo, Siemens, Mitsubishi, Fujitsu, Hitachi, InterDigital and Even so, some of the patents required for 3G may not have been announced patent holders. Nortel and Lucent are believed to have the undisclosed patents required for these standards. In addition, the existing 3G Patent Platform Partnership patent pool has little impact on FRAND's protection as it excludes the four largest 3G patent holders. Loburhanstandard and say that the bets he determines will not be met. In the commentary, that is expected that the IMT-2000 will provide higher transmission speeds: a minimum data rate of 2 Mbps for landline or walking users, and 348 kbps in a moving car, in fact ITU does not clearly specify the minimum required rates, nor require an average rate, no clarification modes are required as 3G, so the various vague rates of data are sold as 3G in the market. In the implementation of the market, the speed of data transmission of 3G, determined by telecommunications service providers, varies depending on the deployed technology; up to 384kbit/s for WCDMA, up to 7.2Mbit/sec for HSPA and a theoretical maximum of 21.6 Mbit/s for HSPA' (technically 3.5G, but usually clubbed under 3G tradename). (quote is necessary) Compare data speed with 3.5G and 4G networks. Security See also: Mobile security and attacks based on GSM 3G networks provide more security than their predecessors 2G. By allowing UE (User Equipment) to verify the authenticity of the network, to it attaches, the user can be sure that the network is a intended, not an imitator. 3G networks use the KASUMI block cipher instead of the old A5/1 stream cipher. However, a number of serious flaws in the KASUMI cipher have been identified. In addition to 3G network infrastructure security, access to the infrastructure basics of an application such as IMS is still offered security, although this is not strictly a 3G feature. 3G Applications Bandwidth and Location Information available for 3G devices leads to applications previously unavailable to mobile phone users. Evolution 3GPP and 3GPP2 are working to expand 3G standards based on IP network infrastructure that use advanced wireless technologies such as MIMO. These specifications already reflect the characteristics specific to IMT-Advanced (4G), the successor to 3G. However, without meeting 4G bandwidth requirements (which is 1 Gbps for stationary and 100 Mbps for mobile work), these standards are classified as 3.9G or Pre-4G. 3GPP plans to meet 4G's LTE Advanced goals, while Kvalcomm has halted UMB's development in favor of the LTE family. On December 14, 2009, Telia Sonera announced in an official press release that we are very proud to be the first operators in the world to offer 4G services to our customers. With the launch of their LTE They initially offer pre-4G (or outside 3G) services in Stockholm, Sweden and Oslo, Norway.
