DMS-MTX DualMode Metrocell Cell Site Description
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.
