  • Methods and apparatus to analyze communication system transceivers
    Patent number: 8447293
    Abstract: Methods and apparatus to monitor communication system transceivers are disclosed. For example, the disclosed system may determine the number and locations of available cellular stations. An example method includes receiving a first message from a base station, receiving a second message from the base station, extracting a first parameter from the first message, extracting a second parameter different from first parameter from the second message, determining if the first message and the second message were received from the same base station based on the first parameter and the second parameter, and reporting that the first message and the second message were from the same base station if the first message and the second message were received from the same base station. Some implementations of the disclosed methods and apparatus enable pseudorandom number codes received over-the-air from base stations to be grouped by base station.
