Calculating 2100 MHz Channel Center Frequencies
T able C -5 shows the valid 2100 MHz CDMA channels, listed in both decimal and hexadecimal,
and the corresponding transmit and receive frequencies for each. Center frequencies (in MHz)
for channels not shown in the table may be calculated as follows:
• TX = 2110 + 0.05 * Channel# Example: Channel 262 TX = 2110 + 0.05 * 262 = 2123.10
MHz
• RX = 1920 + 0.05 * Channel# Example: Channel 262 RX = 1920 + 0.05 * 262 = 1933.10
MHz
Actual frequencies used depend on customer CDMA system frequency plan.
Each CDMA channel requires a 1.77 MHz frequency segment. The actual CDMA carrier is 1.23
MHz wide, with a 0.27 MHz guard band on both sides of the carrier .
Minimum frequency separation required between any CDMA carrier and the nearest
NAMPS/AMPS carrier is 900 kHz (center -to -center).
