0G to 5Gl

  1. 1.  Mobile wireless technology came early in 1970s.  Mobile Wireless Technology has experienced different generations of Technology mainly from 0G to 4G. Implementation work of 5G is going on.  Mobile radio telephone systems (0G) preceded modern cellular mobile telephony technology.  The mobile wireless communication was possible only by the introduction of 1G technology.  2G technology replaced the analogy technology by digital communication .
  2. 2. 0G 1946 - 1978 1G 1978-1995 2G 1991-Now 3G 2003-Now 4G 2008 - Now ?
  3. 3.  MTS(Mobile Telecommunication service) • Analog system telecommunication • Setup By Operator • There were initially only 3 channels for all the users in the metropolitan area
