Wireless mobile data technology has been advancing in the last decades have been able to see great changes and also seen great impact. There have been large advancement in wireless technology since inception. We have had the mobile generation technology evolve from 1G to the current one 5G which is more advanced than the rest. This advancement has been accomplishing various goals at their different stages. In the last decade, we have witnessed a lot of progress in regards to the mobile data generation let’s look at a various generation at a glance from 1G to the thrilling 5G technology.

The first generation technology (1G) was introduced in the year 1979 in Tokyo Japan. Then the mobile phones were built in cars. They had a cellular network with 88 cell sites that had radio towers covering all the districts of Tokyo. In 1981 Norway and Sweden created the first one g mobile network based on Nordic mobile telephone (NMT). Most phones in this era weighed 3-4Kg. lol! I know that sounds crazy now. The 1G gadgets were very expensive going for about 3000$. This meant that only a few people had devices. They were for the super-rich and people of a very high class.

1G in summary

  • Speed of up to 2.4Kbps
  • Poor sound/voice quality
  • Analog mode of communication
  • Limited coverage voice calls were in a small location
  • Weak security prone to interference

The second-generation technology (2G) came to solve various challenges that 1G had. It emerged in the late 1980s. It was based on GSM (Global System for Mobile communication) which was established in 1988. Unlike the previous generation used digital signals in its transmission. It’s advancement yielded to the use of SMS (Short Messaging Service). Eng. Neil Papworth became the first person to send an SMS in 1992 his message was “Merry Christmas”.

2G in summary

  • Speed of up to 64Kbps
  • Better quality and capacity
  • Improved to allow phone calls
  • Allowed sending and receiving emails
  • Allowed the use of picture messages (MMS)

GSM technology was later upgraded to 2.5G to provide better services. It utilized General Packet Radio Service (GPRS) which supports packet switching for data rates up to 160Kbps. Around 1997  there was an introduction of Enhanced Data Rates for GSM Evolution (EDGE) many referred to it as 2.75G whose speed went up to 500Kbps.s

The third-generation mobile data technology (3G), is the most widely known it was an upgrade of GPRS and EDGE. It was also based on GSM and was launched in 2000. It was also known as IMT 2000. 3G revolutionized television production, video streaming and video calls, clarity of the data sent increased. 3G  technology is commonly used in smartphones and laptops. It leads to high usage of the internet since inception. Its speed is 10 x more than the 2G. With the 3G there was the introduction of the Global Positioning System which is used to determine the ground location of objects and even ourselves.

3G in summary

  • Its speed of up to 10Mbps
  • High-speed web browsing
  • Video conferencing, and High bandwidth requirements
  • The capability of sending larger emails
  • High-quality picture and video
  • The phones were expensive

This are the three generations that kicked off our mobile data technology, in my next artcle in this section I will be sharing on the remaining 2. 4G and 5G. Any comment of question kindly leave it in the comment section below.
