800 MHz CDMA Channels
Figure D-2 shows the valid channels for the North American cellular
telephone frequency spectrum. There are 10 CDMA wireline or
non–wireline band channels used in a CDMA system (unique per
customer operating system).

Calculating 800 MHz Center
Frequencies
Table D-2 shows selected 800 MHz CDMA candidate operating
channels, listed in both decimal and hexadecimal, and the corresponding
transmit, and receive frequencies. Center frequencies (in MHz) for
channels not shown in the table may be calculated as follows:
S Channels 1–777
TX = 870 + 0.03 * Channel#
Example: Channel 262
TX = 870 + 0.03*262 = 877.86 MHz
S Channels 1013–1023
TX = 870 + 0.03 * (Channel# – 1023)
Example: Channel 1015
TX = 870 +0.03 *(1015 – 1023) = 869.76 MHz
S RX = TX – 45 MHz
Example: Channel 262
RX = 877.86 –45 = 832.86 MHz
