INCEPTION OF WIRELESS 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.
