The 5G terminals will be a reconfigurable multimode and cognitive radio- enabled. It will have software defined radio modulation schemes. All the required reconfigurable software should be downloaded from the Internet on the run. The 5G mobile networks will focus on the development of the user terminals.
Generations of Mobile Technology
Figure 1
0G Technology: The first generation of technology is a mobile radio telephone called 0 (Zero) Generation telephone system includes transceiver, dial, display and handset. It is also called Radio Common Carrier (RCC)
1G Technology: In 1980, the analog telecommunication system was included in telephone technology which was introduced as 1G technology. This technology has just an analog system with bandwidth up to 30kHz.
2G Technology: The digital communication system came into the market with 2G technology which makes spectral bandwidth possible up to 200kHz and SMS services among cellular phone users. GSM and CDMA are two systems of 2G technology. The text messaging service is the best part of 2G technology.
2.5G Technology: This technology includes a GPRS system with a packet data internet service. The MMS and mobile internet with WAP (Wireless Application Protocol) are the new features of 2.5G technology.
2.75G Technology: The GPRS system with EDGE (Enhanced Data rates for GSM Evolution) feature was possible because of 2.75 Technology that starts the advance technology in GSM internet system.
3G Technology: High speed internet on mobile, video calls and mobile TV are new features of 3G technology. 3GPP is a group of CDMA2000 and UMTS which broadcast internet speed up to 2 MBPS with high data rate. 3.5G and 3.75G technologies are something like 3G technology and includes features similar to a 3G system.
4G Technology: It’s the latest technology system used in the current mobile phone market. The mobile ultra-broadband internet access, video conference, 3D television and LTE (Long Term Evolution) are new features of 4G technology. 4G-LTE is a completely new technology that makes possible data transfer capacity up to 100MBPS and spectral bandwidth up to 40 MHz.
Architecture of 5G Mobile Telephony
A first remarkable feature of 5G network is the broadband internet in mobile phones that would be possible to provide internet facility in the computer by just connecting the mobile as depicted in figure 3.
Handheld Computer: Data sharing in 5G network is very easy. It omits the condition of putting both mobile face to face so that data could be shared. But 5G Bluetooth technology removes this condition and data could be transferred if it is shared in the range of 50m. It is not far away when we see the global mobiles all over the world.
A user can move everywhere in the world by holding just 5G mobile network. All the roaming would be exempt from the tariff plans. The rates of the call would not be different area to area. Figure shows the system model that proposes 5G – Introduction & Future of Mobile Broadband Communication Redefined 121 design of network architecture for 5G mobile systems, which is all-IP based model for wireless and mobile networks interoperability. The system consists of a user terminal (which has a crucial role in the new architecture and a number of independent, autonomous radio access technologies. Within each of the terminals, each of the radio access technologies is seen as the IP link to the outside Internet world.
Figure 2
Components of 5G Network Physical Layer / MAC Physical and Medium Access Control (MAC / PHY) is the first layer and second layer of the OSI (Open Systems Interconnect) which defines the wireless technology. In the second layer, the 5G cellular network tends to be based on pen Wireless Architecture (OWA).
Network Layer
Layer of the network used is most likely the IP (Internet Protocol) because no one else that can compete with the IP. Internet Protocol version 4 (IPv4) has spread almost all over the world and have some addressing issues such as limited space and lack of a definite possibility for QoS in support of each stream. These issues have been solved by IPv6, but IPv6 packet header traded with far greater. This makes the movement still has problems.
All mobile networks will use IP phones in the 5G, and any cellular connection using the FA (Foreign Agent), CoA (Care of Address) equipment to map the IPv6 fixed address and CoA address for the wireless network is now used. Phones can be attached to multiple cellular or wireless network at the same time. In some cases, it can maintain IP addresses are different for each radio interface, while each IP address will be for the FA CoA address placed on a cell phone. IPv6 has been enhanced to be applied on a cell phone 5G. 5G mobile phone will keep the wireless multivirtual network environment.
To that end, the network layer must be divided into two sub layers in the 5G cellular network, the Lower Network Layer (for each interface) and Upper Layer Network (for a cellular connection). The division is because the initial design of the internet, where all the routes based on IP addresses that should be different in each IP networks around the world. Middleware between the upper and lower layers of the network will retain the address of the network address translation upper (IPv6) to the IP address of a different lower network (IPv4 or IPv6), and vice versa.
Open Transport Layer Protocol (OTA)
Cellular and wireless networks differ from wired networks associated with the transport layer (Transport Layer). In all versions of TCP, segments are lost due to the blockage of the network, while on the wireless network, the loss of the 122 R. Gowri Shankar Rao & Ravali Sai segment is likely to occur due to error ratio is slightly larger in the radio interface. Therefore, the proposed TCP modification and adaptation for mobile and wireless networks, which sends back the parts are missing or damaged TCP is done only through a wireless link. For 5G phones, the connection would be appropriate to have a transport layer that allows it to be downloaded and installed. Each cell must have the ability to download such as TCP, RTP, or new transport protocol that is targeted to a specific wireless technology installed at the BTS. This is called Open Transport Protocol (OTP).
Application Layer
Speaking about the application, the main message of the 5G cellular connection is to provide intelligent QoS management through a diverse network. Today, in the mobile phone user can manually select the wireless interface to a particular internet service without having the ability to use the QoS history to choose the best wireless connection to a particular service. 5G telephone service must provide the ability for quality testing and measurement of information storage in the database of information on cellular connections. QoS parameters such as delay, loss, wide band, reliability, will be deposited into the cell phone database 5G with a view used by intelligent algorithms that run on cellular connections as a processing system, which in turn should provide the best wireless connection to one’s limitations and costs QoS is required.

5G Applications
5G mobile phone concept is proposed as an open platform designed in different layers, from physical layer to application layer. The proposed concept of adjusting to the Open Wireless Architecture (OWA).
The network layer is divided into two sub-layers to provide all IP connectivity in an environment surrounded by cellular or wireless technologies such as network providers and service providers. Open transport layer is proposed in order to allow the use of specific implementations of the protocol-protocol wireless carrier. 5G mobile phone concept is also possible to select a different wireless technologies to include the cost of QoS constraints.
To that end, 5G cellular network connection capable of providing the best QoS with the lowest prices for certain services provided using one or more wireless technologies at the same time from a cell phone 5G
