Abstract:
1. A method for CDMA signal testing at indoor and other locations where a global time synchronization signal is obstructed from a signal tester comprising: receiving periodically the global time synchronization signal at a local CDMA transmitter to periodically set an internal clock of the local CDMA transmitter; transmitting at least one signal from the local CDMA transmitter; marking the at least one local CDMA transmitter signal with a unique pattern; including time information in the at least one local CDMA transmitter signal; receiving the at least one local CDMA transmitter signal containing the time information and the unique pattern at a signal tester that is otherwise obstructed from receiving the global time synchronization signal; receiving at the signal tester at least one signal from a CDMA base station; distinguishing at the signal tester the at least one CDMA base station signal from the at least one local CDMA transmitter signal, wherein the signal containing the unique pattern is identified as the at least one local CDMA transmitter signal; setting an internal clock within the signal tester based on the time information included in the at least one local CDMA transmitter signal; measuring at the signal tester the at least one CDMA base station signal; and evaluating at the signal tester the at least one CDMA base station signal for signal propagation and coverage.
