The activity of taxicab fleets is usually monitored and controlled by a central office, which provides dispatching, accounting, and human resources services to one or more taxi companies. Taxi owners and drivers usually communicate with the dispatch office through either a 2-way radio or a computer terminal, called a mobile data terminal.
Taxi frequencies are generally licensed in duplex pairs. One frequency is used for the dispatcher to talk to the cabs, and a second frequency is used to the cabs to talk back. This means that the drivers generally cannot talk to each other. Some cabs have, or had a CB radio in addition to the company radio so they could speak to each other without interfering with the dispatcher.
In the United States, there is a Taxicab Radio Service [LX] now merged with Business Radio Service [IB] with pairs assigned for this purpose. A taxi company can also be licensed in the Business Radio Service. Business frequencies in the UHF range are also licensed in pairs to allow for repeaters, though taxi companies usually use the pair for duplex communications.
The FCC Rules and Regulations for the TaxiCab Radio Service [LX] is Sec. 90.93
