Devices and methods are provided for providing self-timing and self-locating in an access point (AP) base station. In one embodiment, the method involves receiving Satellite Positioning System (SPS) signals from a first data source (e.g., plurality of satellites), wherein the SPS signals may include SPS time data, SPS frequency data, and SPS position data. The method may further involve obtaining from a second data source (e.g., cell site, terrestrial navigation station, server, user input interface, etc.) at least one of second time data, second frequency data and second position data, and determining relative reliability of the first and second data sources.

Method and system for femto cell self-timing and self-locating

A system for displaying performance characteristics of a circuit in a telecommunications network. The system is adapted for use with a CDMA telecommunications network and includes a Markov call testing system for performance testing the telecommunications circuit. A computer stores the results of the performance test. Software running on the computer determines a subset of the results sufficient to reflect the performance of the telecommunications circuit. A monitor on the computer displays information corresponding to the subset. In the illustrative embodiment, the system further includes a method for determining if one or more receive antennas in the telecommunications network are balanced. The telecommunications circuit corresponds to a cell site modem chip in a base station. The subset includes a number of finger signal peaks. The number is determined by calculations performed on a scan set to determine a floor above which signal peaks are chosen for inclusion in the subset. In the specific embodiment, the subset includes the eight highest signal peaks of a scan set. The scan set corresponds to a set of signal peaks as is provided by a temporal analyzer. In the illustrative embodiment, the display shows finger signal peak data resulting from Markov call testing of a cell site modem chip having one or more fingers. A first field in the display depicts a subset of signal peaks that includes n of the highest signal peaks. A second field illustrates an operational state for each of the fingers.
