Origin of Cellular Telephony


0

1947

 

Bell Laboratories introduced the idea of cellular communications with the police car technology. The basic concept of cellular phones began, when researchers looked at crude mobile (car) phones and realized that by using small cells (range of service area) with frequency reuse they could increase the traffic capacity of mobile phones substantially. However at that time, the technology to do so was nonexistent

1968

 

AT&T and Bell Labs proposed a cellular system to the FCC of many small, low-powered, broadcast towers, each covering a ‘cell’ a few miles in radius and collectively covering a larger area. Each tower would use only a few of the total frequencies allocated to the system. As the phones traveled across the area, calls would be passed from tower to tower.
