GSM/HSPA/GPRS Antenna Requirements/Specifications
824 – 960 MHz / 1710 – 1990 MHz
VSWR shall not exceed 2.0:1 at any point across the bands of operation
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
Do not alter 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.
