Title: Radio Telephones - Description Post by: Daniel Franklin on October 13, 2007, 03:26:22 PM Radio telephones are communication devices, which allow two people to talk to one another using a radio. Although they are similar to cell phones for practical purposes, they work somewhat differently, operating on radio frequencies of 60 to 900 MHz. A "walkie talkie" is an example of a simple radiotelephone. In recent years, the popularity of cell phones has made the radiotelephone largely obsolete as a consumer device, but they are still used in police communications, and by Private Mobile Radio (PMR) networks.
