The generation of Mobile Network from the first generation in the 1980s to the fifth generation in year 2020 has evolved over time with a lot to technological advancement. Below is a brief order of the technologies.

• 1G: This is the first generation of wireless telephone technology. It is the only analog radio signal  telecommunication standards that has been till date and was introduced in 1979 and the early to mid 1980s. After this phase the 1G network was replaced with the 2G network which started the digital radio signal era.
  digital signaling is also used for voice on a 1G system (Phone) but the signal is always modulated to higher frequency in other to connect to other radio signals.
• 2G: 2G cellular networks were commercially launched on the GSM standard in Finland by Radiolinja in 1991.The 2G mobile networks has a lot of benefits over the 1G mobile network.
  • Introduction of SMS (Short Messaging System)
  • Introduction of MMS (Multimedia Messages)
  • Picture Message
  • Enabled more user in each frequency band
  • Made use of the radio frequency Spectrum
  • Phone conversation were digitally encrypted with only the intended receiver getting the messages/calls

  In no time the 2G network also increased its data transfer speed while introducing the 2.5G (General Package Radio Service [GPRS]) with a transfer speed of 40kbps and then to the 2.75G (Enhanced Data Rates for GSM Evolution [EDGE]) with a data transfer speed of 384kbps

   

• 3G: 3G technology introduced mobile data and fast internet to the mobile world as the technology become faster and gave access to several Mbps to smartphones and mobile modems in laptop computers. This also applied to:
  • wireless voice telephony
  • mobile Internet access
  • fixed wireless Internet access
  • video calls
  • mobile TV technologies.
  • etc.

  New generation of cellular standards appear to be released approximately every ten years since the 1G technology system was introduced in 1981/1982 with each generation characterized by new frequency bands and on the higher degree. The first 3G networks were introduced in 1998

• 4G: in addition to the usual voice and other services gotten from the 3G Network, brought to rise the mobile broadband Internet access and the following facilities:
  • amended mobile webaccess
  • IP telephony
  • gaming services
  • high-definition mobile TV
  • video conferencing
  • 3D television
  • cloud computing
  • etc.

  Also, the 4G LTE (Long Term Evolution)in its acquired 700MHz Band was also commercially deployed in Norway and Stockholm in 2009 and in the United States by Verizon in.

  The Outbreak of 4.5G also provides better performance than 4G systems, as a process step towards deployment of full 5G Technology capabilities.

  5G: 5G Technology is the fifth generation of wireless communications technologies supporting cellular data networks. Read about 5G Network HERE!
