A.2 Performance of Transmitter
A.2.1 Frequency Requirements
I. Frequency coverage
450MHz band: 460 - 470MHz
800MHz band: 869 - 894MHz
1900MHz band: 1930 - 1990MHz
II. Frequency tolerance
Within the working temperature range, the average difference between the actual
carrier frequency of CDMA transmit sector and the carrier frequency of the dedicated
transmit sector is less than !5%10
A.2.2 Modulation Requirements
I. Synchronization and timing
Time tolerance for pilot frequency: The pilot time alignment error should be less than 3
µs and shall be less than 10 µs. For BTSs supporting multiple simultaneous CDMA
