If you are planning on intercepting
these, do it from Canada as I'm fairly certain these freqs are covered by
the ECPA.
Some people in our hobby find that listening to 800 mhz cellular
communications is interesting. Those who do, might find that some real
inside, juicy stuff could be found being broadcast from the private jets
carrying entertainment industry executives, business leaders, and
goverment officials across this great land of ours.
The frequency assignments are as follows:
Channel Ground Plane
1 454.950 459.950
2 454.900 459.900
3 454.850 459.850
4 454.800 459.800
5 454.750 459.750
6 454.700 459.700
7 454.725 459.725
8 454.775 459.775
9 454.825 459.825
10 454.875 459.875
11 454.925 459.925
12 454.975 459.975
CALL 454.675 459.675
The Ground stations broadcast an annoying tone when not in use. The
Planes broadcast in simplex only, while the Ground station broadcast
duplex similar to cordless phone base/handset operation. The easiest way
to monitor this service is to load first a Plane frequency then a Ground
frequency for each channel. After loading all the channels go back and
lock out all of the Ground frequencies. Scan the Plane frequencies for
simplex transmissions and when you get a hit, press your manual key to
jump to the next frequency... the locked out ground frequency
broadcasting in duplex!
Please keep in mind that the services provided on these frequencies are
Common Carrier and perhaps subject to the same laws covering the
monitoring of Cellular Phones. In which case it is a violation of
federal law to listen to these frequencies.
The FCC has issued rules on allocation of the 849-851/894-
895 MHz bands for air-ground radiotelephone service.
The new action, effective September 9, 1991:
1) changes channel spacing from GTE Airfone Inc.'s de
facto standards;
2) orders GTE to make its service available to other
air-ground licensees at non-discriminatory rates;
3) divides each channel block into 6 control channels
(P-1 through P-6) and 29 communications channels
(C-1 through C-29);
4) provides for a communications channel bandwidth of 6
kHz;
5) gives 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) empowers the FCC to assign exclusively one control
channel to each air-ground licensee;
7) limits the ERP of airborne stations to 30 watts;
maximum, and that of ground stations to 100 watts
maximum;
8) limits the ERP of ground stations to 1 watt when
communicating with aircraft on the ground.
(ground stations using the same channel block must be at
least 300 miles apart)
