AIRFONE FREQUENCIES ------------------- Copied by: John Johnson, KWV8BP Source: Monitor America On October 15, 1984, Airfone, Inc. began to offer air-to-ground telephone service for commercial airline passengers. Using special cordless Tele- phones which accept standard credit cards, the system offers three-minute calls for a minimum charge of $750. A network of ground stations carries the transmissions; computer control "hands off" calls from one gound station to another as airliners move in & out of range. Thirty-two channels are assigned to each transmission site, following the same pattern in each case except for the lowest frequency assigned. All stations transmit on AM single sideband (A3A).
