If you have been around for a while, you are a witness to the fastest evolution of technology in history. Wireless Phones (also called mobile phones and cell phones) are no exception to this statement. Since 1983 ,they changing shape so fast that it is breathtaking to watch to advancements. If someone slept all the time from 1980′s to this day, It would be very difficult for him to recognize most of the stuff around him. He sure will be unable to tell the use of an iPhone.Â It is indeed very hard to find a similarity between a Motorola DynaTAC 8000X( from 1983) and Apple’s iPhone(2007).
Wireless technology behind the wireless phone also evolved from 1G to 3G over time. According to techbiz.blog.com
First generation of cellphones (1G) used analog signal transmission technique for communication between mobile and base stations. FDMA (Frequency Division Multiple Access) was the de facto protocol for distributing available frequency band among concurrent users. 1G cellphones were predated by mobile radio telephone technology (usually considered as 0G). Both 0G and 1G supported basic voice communication only.
2G introduced digital signal transmission technique along with TDMA (Time Division Multiple Access) and CDMA (Code Division Multiple Access) protocols. 2G needs much more careful consideration in order to understand the cellphone convergence as the two most prominent standards groups in worldwide cellular arena today â€“ GSMA and CDG â€“ have their roots here.
