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).

Channeling Plan
|
|||
|
|
|
|||
|
|
Channels are separated by 6 KHz except for the last channel assigned to each
|
|||
|
|
location, which is 10 KHz higher than the preceding channel. For example, if
|
|||
|
|
the first channel in a group is 944.204, the sequence would be:
|
|||
|
|
|
|||
|
|
|
|||
|
|
944.204 944.210 944.216 944.222 944.228 944.234 944.240
