Channel designation and frequency assignment

System	Channel	Cell site receive	Cell site transmit
		frequency (MHz)	frequency (MHz)
Not used	990	824.010	869.010
A"	991 - 1023	824.040 - 825.000	869.040 - 870.000
A	1 - 333	825.030 - 834.990	870.030 - 879.990
B	334 - 666	835.020 - 844.980	880.020 - 889.980
A’	667 - 716	845.010 - 846.480	890.010 - 891.480
B’	717 - 799	846.510 - 848.970	891.510 - 893.970

The relationship between the channel number (N) and the frequency is:

Channel number: 1 ≤ N ≤ 799

Receiver frequency (in MHz) = 0.03N + 825.000

Transmit frequency (in MHz) = 0.03N +870.000

Channel number: 990 ≤ N ≤ 1023

Receiver frequency (in MHz) = 0.03(N - 1023) + 825.000

Transmit frequency (in MHz) = 0.03(N - 1023) + 870.000

Both non-expanded and expanded spectrums are shown in Appendix B for the N=7 and N=4 frequency groups.

Important

For ALL Metrocell cell site configurations, the frequency plan used should have a minimum of 21 channel spacing (630 kHz) between the RF channels.
