This is a quick file on the subject of what frequencies are used for Air Fone
Telephone while in-flight air-to-ground.  The following should give you some an
understanding of how it all works.

The FCC has issued rules on allocation of the 849-851/894-895 MHz bands for
air-ground radiotelephone service.

The most recent action was effective September 9, 1991:

     1) Changed channel spacing from GTE Airfone Inc.'s de facto standards;

     2) Ordered GTE to make its service available to other air-ground licensees
        at non-discriminatory rates;

     3) Divided each channel block into 6 control channels (P-1 through P-6)
        and 29 communications channels (C-1 through C-29);

     4) Provided for a communications channel bandwidth of 6 kHz;

     5) Gave GTE 22 months to modify its current control channel scheme; during
        this period, GTE can use the lower 20 kHz of each channel block, which
        includes channels C-1, C-2, and C-3, for control.  GTE then has another
        38 months during which it can only use a 3.2 kHz control channel in
        channel C-2 of each channel block.  After these transition periods end
        (September of 1996), GTE must switch to control channels marked P-1
        through P-6 in the tables below;

     6) Empowered the FCC to assign exclusively one control channel to each
        air-ground licensee;

     7) Limited the ERP of airborne stations to 30 watts maximum; and that of
        ground stations to 100 watts maximum;
 
     8) Limited the ERP of ground stations to 1 watt when communicating with
        aircraft on the ground.

(NOTE:  "GB" in these listings denotes Guard Band, a series of 3 kHz spacings
 to separate communications channels from control channels.)
