CDMA 800 MHz Channel Numbering
General information:
The 800 MHZ CDMA channel numbering evolved
from the Amps analog system which shares the
same spectrum.
The Amps channel spacing is 30 KHz, because the
CDMA signal BW=1.25 MHz, the actual CDMA
signal must be spaced every 41 channels
(41*30 KHZ = 1.23MHZ)
In a dual-mode system, CDMA signals would
never occupy analog control channels 313 to 354.
A -System preferred channels: primary =283,
Secondary = 691
B- System preferred channels: Primary =384,
Secondary = 777
The lowest valid CDMA channel is 1013.
The highest valid CDMA channel is 777.
