Antenna Loss
Free space not to exceed -3db
TRP/TIS
Including cable loss the total radiate power (TRP) at the antenna shall be
no less than +22/24.5 dBm for 850/1900 MHz respectively, and the total
isotropic sensitivity (TIS) at the antenna shall be no less than -99/101.5
dBm for 850/1900 MHz respectively.
PTCRB Requirements for the Antenna
There cannot be any alteration to the authorized antenna system. The antenna system must maintain the same specifications.
The antenna must be the same type, with similar in-band and out-of-band radiation patterns.
