Way, way, way back in the day there was Mobile Telephone Service [0]. Instead of a cellular network it was just a two-way VHF radio. MTS was operator dialed which meant you picked up your end in the car and an operator dialed a landline and patched it through to the radio. When cellular phones debuted in the 80s they were described as such to distinguish them from MTS phones. The MTS phones needed a whole channel assigned to a phone which was dedicated in the whole service area. Cellular systems allowed geographic channel reuse so you could have a lot more users in a given area. [0] https://en.m.wikipedia.org/wiki/Mobile_Telephone_Service |
