|Mobile phones started life as the two way radio, which was also called mobile rigs. These were installed in vehicles such as minicabs, police cars and ambulances, but were not strictly mobile phones as they were not normally connected to the telephone network. While the very first mobile phones were installed permanently in vehicles, later versions such as the transportable, also called bag phones, could also be carried, and can be used as either portable or as mobile two-way radios. |
