  11. This is a quick file on the subject of what frequencies are used for Air Fone
  12. Telephone while in-flight air-to-ground.  The following should give you some an
  13. understanding of how it all works.
  14.  
  15. The FCC has issued rules on allocation of the 849-851/894-895 MHz bands for
  16. air-ground radiotelephone service.
  17.  
  18. The most recent action was effective September 9, 1991:
  19.  
  20.      1) Changed channel spacing from GTE Airfone Inc.'s de facto standards;
  21.  
  22.      2) Ordered GTE to make its service available to other air-ground licensees
  23.         at non-discriminatory rates;
  24.  
  25.      3) Divided each channel block into 6 control channels (P-1 through P-6)
  26.         and 29 communications channels (C-1 through C-29);
  27.  
  28.      4) Provided for a communications channel bandwidth of 6 kHz;
  29.  
  30.      5) Gave GTE 22 months to modify its current control channel scheme; during
  31.         this period, GTE can use the lower 20 kHz of each channel block, which
  32.         includes channels C-1, C-2, and C-3, for control.  GTE then has another
  33.         38 months during which it can only use a 3.2 kHz control channel in
  34.         channel C-2 of each channel block.  After these transition periods end
  35.         (September of 1996), GTE must switch to control channels marked P-1
  36.         through P-6 in the tables below;
  37.  
  38.      6) Empowered the FCC to assign exclusively one control channel to each
  39.         air-ground licensee;
  40.  
  41.      7) Limited the ERP of airborne stations to 30 watts maximum; and that of
  42.         ground stations to 100 watts maximum;
  43.  
  44.      8) Limited the ERP of ground stations to 1 watt when communicating with
  45.         aircraft on the ground.
  46.  
  47.  
  48. GROUND TO AIR CHANNELS
  49.  
  50. (NOTE:  "GB" in these listings denotes Guard Band, a series of 3 kHz spacings
  51.  to separate communications channels from control channels.)
