For Tenants that require a different number of RF channels, then the forward PA output
powers are changed using the following equation:
• Forward PA output change = 10*log10(baseline # RF channels /new # RF channels).
For example, if a PCS/CDMA WSP requires 6 RF channels, then the forward PA output power
per RF channel is adjusted by 10*log10(3/6) = -3.0 dB. The per RF channel power is changed
from 34 to 31dBm.
If the operator requires a different reverse link budget, then the simulcast # can be changed.
The equation for this calculation is:
• New simulcast # = (baseline simulcast #) / 10^(Reverse link budget change/10)
For example, if a Cellular/CDMA WSP requires a change of +3dB in the reverse link budget,
then the simulcast # is changed to (8 / 10^(3/10)) = 4;
The following tables define the RAN output power as a function of:
• Carrier count
• Maximum composite PA output power
• RAN configuration (4 or 8 Tenant RAN)
All numbers are in dBm except for carrier counts.
