Airbridge cBTS3612 CDMA Base Station
A.1.4 Receiving Performance
I. Sensitivity
450MHz band and 1900MHz band:
The R-TCH FER shall be <1.0% with 95% confidence when -126dBm/1.23MHz
CDMA RC3 signal level is inputted at BTS RF main and diversity input ports.
800MHz band:
The R-TCH FER shall be <1.0% with 95% confidence when -127dBm/1.23MHz
CDMA RC3 signal level is inputted at BTS RF main and diversity input ports.
II. Receiver dynamic range
450MHz band and 1900MHz band:
The
R-TCH
-126dBm/1.23MHz~ -65dBm/1.23MHz CDMA signal level is inputted at BTS RF main
and diversity input ports.
800MHz band:
The
R-TCH
-127dBm/1.23MHz~ -65dBm/1.23MHz CDMA signal level is inputted at BTS RF main
and diversity input ports.
III. Single-tone desensitization
450MHz band:
Input the single-tone interference deviated from the center frequency at the BTS RF
input port: when the single-tone interference deviates from the center frequency
+900kHz and -900kHz, the input single-tone interference power is 87dB higher than
the output power of the mobile station simulator. When R-TCH FER maintains <1.5%,
the output power of mobile station simulator changes less than 3dB whether there is
single-tone interference or not.
800MHz band:
Input the single-tone interference deviated from the center frequency at the BTS RF
input port: when the single-tone interference deviates from the center frequency
about + 750kHz and -750kHz, the input single-tone interference power is 50dB higher
than the output power of the mobile station simulator; when the single-tone
interference deviates from the center frequency +900kHz and -900kHz, the input
single-tone interference power is 87dB higher than the output power of the mobile
