ABSTRACT 4G TECHNOLOGIES Wireless technology has transformed our lives in many ways. Until very recently‚ we needed a computer wired to a port‚ to get online. Even wired telephones are becoming a thing of past. Nowadays‚ we use our mobile phones for banking‚ to check ticket availability at a Cinema Hall‚ and many more. Wireless communication is the transfer of information over a distance without the use of enhanced electrical conductors or "wires”. And‚ Wireless networking refers to any kind

Microwave Oven Who invented the Microwave oven Percy Spencer invented the first microwave oven after World War II from radar technology developed during the war. Named the "Radarange"‚ it was first sold in 1946. Raytheon later licensed its patents for a home-use microwave oven that was first introduced byTappan in 1955‚ but these units were still too large and expensive for general home use. The countertop microwave oven was first introduced in 1967 by the Amana Corporation‚ which was acquired in
