Technology

Hello, i had to pick a type of technology and i picked cell phones along with my group, randy, and crystal, and here is some info about cell phones: At first, two-way radios(known as mobile rigs) were used in vehicles such as taxicabs, police cruisers, and ambulances, but were NOT mobile phones because they were NOT normally connected to the telephone network. Users COULD NOT dial phone numbers from their mobile radios in their vehicles.
