Then in case of 2G Narrow Band Wireless Digital Network is used. Both the 1G and 2G deals with voice calls and has to utilize the maximum bandwidth as well as limited to sending messages i.e. SMS. In 3G Wide Band Wireless Network is used with which the clarity increases and gives the perfection as like that of a real conversation. In addition to verbal communication it includes data services, access to television/video, categorizing it into triple play service. 3G operates at 2100MHz and has a bandwidth of 1520MHz . -

In-cell touch by Vcom blocks has been a dominant touch technology for thin-film-transistor liquid- crystal display (TFT-LCD) displays in mobile phone application. However, the growth has slowed down after its high penetration rate. Panel makers will extend the technology to larger-sized tablet and notebook PC applications. Panel makers will prioritize the in-cell touch development for tablet PC application because of its bigger market size. The in-cell touch technology for notebook PC application will grow remarkably from 2021 onwards. Although in-cell touch by Vcom blocks already accounts for more than 93% shipment shares of the total in- cell TFT-LCD shipments in mobile phone application, it seems that its remarkable growth in recent years will end soon (78% YoY in 2018 and 56% YoY in 2019). The reason is that AMOLED display demands, including on-cell and GF2 touch sensors, are surging and they are replacing in-cell TFT-LCD, especially in the midrange and high-end segments. Furthermore, two in-cell touch technologies—Apple’s Vcom pattern type and Japan Display’s (JDI) hybrid type—are declining because major smartphone brands are shifting to on-cell AMOLED. -

History of Mobile Telephony MAS 490: Theory and Practice of Mobile Applications
History of Mobile Telephony MAS 490: Theory and Practice of Mobile Applications Professor John F. Clark Everything I know about mobile telephony, I learned from: Evolution is not a theory when it concerns cell phones Early History of Radiophones Nicola Tesla and Guglielmo Marconi were the founders of wireless technology Ship to shore radiotelegraphy employed wireless use of Morse Code Later, radiophones and radiotelephony transmitted speech In 1900 Reginald Fessenden invented early broadcasting, transatlantic two-way voice communication, and later television Tesla, Marconi, and Fessenden The Great Wireless Fiasco Early History of Radiophones In 1926 radiophones connected people traveling on trains in Europe A little later, they were introduced in planes, but this was too late for World War I Radiophones made a huge difference in WWII – planes, tanks, and field communication via backpack radios and walkie-talkies. Later, in the 1950s, radiophones made civil and commercial services possible Military Field Communications Civil Field Communications Civil Field Communications, pt. 2 Early History of Mobile Telephony The 60s and 70s saw a variety of commercial car services – the earliest weighed 90-100 pounds These services operated using high power transmissions The concept of low power transmission in hexagonal cells was introduced in 1947 The electronics were advanced enough by the 60s to pull it off, but there was no method for handoffs from one cell to the next High Power Mobile Phone Low Power Mobile Phone System Early History of Mobile Telephony That problem was solved with the first functioning cell system and first real cell phone call in 1973. The phone, which weighed about six pounds, was developed by Martin Cooper of Motorola Bell Labs and Motorola were the main competitors in the US. -

Motorola Micro Tac Classic
Motorola Micro Tac Classic Product: Motorola Micro Tac Classic Date of Design: 1992 Designer / Retailer: Motorola Cost 1992: - Cost 2007: £40 Retro Brick state… The Motorola MicroTAC phone set a new design standard for 1989 with a flip-lid mouthpiece. As the smallest and lightest phone on the market, the unit weighed 12.3 ounces, measured 6.75 x 2.25 x 1.25 inches and retailed between £1,200 and £1,800… ouch. This phone is actually third generation of this particular design and was launched in 1991/2 ‘This was a whole new direction for Motorola. New technological advances meant that the equipment could be radically downsized. And so began the quest to be the smallest, lightest and most portable. The original MicroTAC was a completely new design and was the first phone to use this radical flip. There are also few things about it which are quite unusual.... The small hole in the front of the flip gave you the impression that there was a microphone in the flip which was positioned directly in front of your mouth, however, the microphone is actually situated just behind a tiny hole in the main part of the phone just between the right hand hinge and the call end button on the bottom right. Another puzzling design feature was the retractable aerial. In fact, the aerial does absolutely nothing as it is purely for show. The unit features an internal antenna, however, the pull up plastic was added after focus groups in the US felt that any phone should have a visible aerial. -

Establishing Galapagos Ke-Tai's Dominant Industrial Design
Annals of Business Administrative Science 16 (2017) 287–300 http://doi.org/10.7880/abas.0170916a Received: September 16, 2017; accepted: October 25, 2017 Published in advance on J-STAGE: November 8, 2017 Establishing Galapagos Ke-tai’s Dominant Industrial Design Atsushi AKIIKEa) Abstract: The folding “clamshell” mobile phone was chosen as the dominant industrial design in the Japanese mobile phone industry due to the importance of mail functionality, and NEC actively pushed this style and acquired major market share. As a result, at the start of the 21st century, the dominant design “Galapagos ke-tai,” unique to Japan, was established. However, this dominant industrial design along with the functionality of these phones became a barrier to the Japanese mobile phone industry when they shifted to smartphones. In other words, a dominant industrial design determined the competitive positions of companies.

Introduction Japanese mobile phones evolved in a unique fashion through a process called “Galapagosization.” As a result of this unique evolution, Japanese mobile phones are generally known as Galapagos ke-tai (ke-tai meaning “mobile phone” in Japanese).
