Cellular phone channel construction
===============================================================================
Here is a method of determining which frequencies are used in a cellular
system, and which ones are in what cells. If the system uses OMNICELLS, as
most do, you can readily find all the channels in a cell if you know just one
of them, using tables constructed with the instructions below.
Cellular frequencies are assigned by channel number, and for all channel
numbers, in both wireline and non-wireline systems, the formula is:
Transmit Frequency = (channel number x .030 MHz) + 870 MHz
Receive Frequency = (channel number x .030 Mhz) + 825 Mhz
"Band A" (one of the two blocks) uses channels 1 - 333. To construct a
table showing frequency by cells, use channel 333 as the top left corner of a
table. The next entry to the right of channel 333 is 332, the next is 331,
etc., down to channel 313. Enter channel 312 underneath 333, 311 under 332,
etc. Each channel across the top row is the first channel in each CELL of the
system; each channel DOWN from the column from the the first channel is the
next frequency assigned to that cell. You may have noted that each channel
down is 21 channels lower in number. Usually the data channel used is the
highest numbered channel in a cell.
"Band B" uses channels from 334 to 666. Construct your table in a similar
way, with channel 334 in the upper left corner, 335 the next entry to the
right. The data channel should be the lowest numbered channel in each cell
this time.

This represents how a cellular system might be laid out. Cells A and B
never share a common border. Neither do B and C, A and G, etc. Cells that
are next to each other are never assigned adjacent frequencies. They always
differ by at least 60 kiloHertz. To track a mobile phone as it changes cells,
let's put the mobile in a B cell. When the mobile switches frequencies, you
know that he could only go to an D, E, F or G cell because A and C have
adjacent frequencies. The two tables below will help you determine which
channel cells can go next to each other. You can contact your local cellular
phone company and see if they have any maps of the cells available. This is
not a sure thing, but it couldn't hurt to try.
Cells that can go next to each other:
Cell Compatible cells
A C, D, E, F
B D, E, F, G
C E, F, G, A
D F, G, A, B
E G, A, B, C
F A, B, C, D
G B, C, D, E
Here is a frequency/cell layout chart. The cell frequencies are used by
the cell site towers, and the mobile frequencies are the input frequencies
used by the cars.

Monitoring of the base sites is obviously going to be easier than
monitoring the mobiles. The cell base sites are towers (usually blue) with a
triangle shaped "head" on top, and sporting a couple of what appear to be
vertical antennas. These base sites have a range of 3-5 miles. If you take a
look at the honeycomb diagram, you can see how they are laid out. The cell
transmitter is in the middle of the cell. It is possible to hear many, most,
or all of the cells in your city, depending on your location. The closer you
live to a boundary, the greater the chances of your being able to receive more
cells. Due to the nature of radio signals, the actual cell shape is more or
less round. However, the hexagon shape lends itself better to show how the
system is laid out. With a circular coverage area, there will be some
overlapping between adjacent cells.

If, for example, you live near the asterisk (*) in the above diagram, you
will be able go easily hear the G, C, E, and A cells you're near. Since the
maximum _practical_ range of a cell is 3-5 miles, you'll be able to hear them
a bit farther away. However, due to the nature of the FM transceivers at the
cell sites (they capture only the _strongest_ signal), you should be able to
hear all seven cells. Which _one_ of each cell you hear will depend on your
location and the strength of the received signal. In the above diagram,
you'll most likely hear the F cell in the upper right, rather than the one on
the left.
Mobile reception is almost a waste of time unless you have an outdoor
antenna. And, since the mobile will be repeated on the cell site, it's better
to listen to the cell frequencies. You may not be able to hear both sides of
the conversation if you listen only to the mobile frequencies!!! It is useful,
however, for determining which channel cell you're in. If you use the antenna
that came with the scanner, mobile range will be decreased down to 1 or 2
miles. By checking the scanner readout against the cell list above
(825.030-844.980 MHz), you can tell what cell the mobile is in. This is also
useful on the cell site frequencies. If you hear someone say, "I'm at the
corner of highway FF and 37," and you know where the cell site antenna is in
that area, you can check the frequency listing above and determine what cell
that antenna belongs to.
