0G (Radiotelephone)


0G (pre-first generation) refers to the earliest public wireless telephone systems. In the US, Motorola and Bell Telephone provided MTS, the first commercial such service available, beginning in 1946.

RCC (Radio Common Carrier) was an alternative to MTS, and was offered from the 1960's into the 1980's, when AMPS (G1) became the prominent technology, with the advent of the cellular network.

As data devices were uncommon at the advent of the 0G era, bandwidth estimates are difficult to ascertain.
