Calculating 1700 MHz Center
Frequencies
Center frequency for channels may be calculated as follows:
Direction
Formula Example
TX 1840 + (0.05 * Channel#) Channel: 1840 + (0.05 + 25) = 1841.25
RX 1750 + (0.05 * Channel#) Channel: 1750 + (0.05 + 25) = 1751.25
– 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).
