Abstract: Techniques are provided for accurately determining actual and prospective location(s) of radio(s) located in a structure and controlled by a shared spectrum system. By more accurately knowing the location(s) of the radios, the shared spectrum system can more efficiently allocate maximum transmission power(s) to the radio(s), enhance corresponding radio coverage area(s), and/or diminish interference to other radio(s) and/or primary user(s).

Abstract: A method for selecting at least one channel for a network element in a shared spectrum communication system is provided. The method includes identifying a plurality of candidate channels of a frequency band of the shared spectrum communication system. For each channel of the plurality of channels, the method further includes: evaluating the channel based on one or more of a plurality of criteria for the network element; scoring the channel based on the evaluation of the channel for the network element; and ranking the plurality of candidate channels based on the assigned scores for each of the plurality of channels. The method further includes selecting at least one channel based on the ranking of the plurality of candidate channels.

Abstract: A method for diminishing passive intermodulation (PIM) is provided. The method comprises: upsampling an uplink baseband modulated signal; upsampling a downlink baseband modulated signal; determining a time delay for the upsampled downlink baseband modulated signal; time delaying the upsampled downlink baseband modulated signal by the determined time delay; estimating a third order PIM distortion (PIMD) product by filtering the time delayed, upsampled downlink baseband modulated signal with a third order power series kernel; generating a first filtered signal by subtracting the estimated third order PIMD product from the upsampled downlink baseband modulated signal; estimating a Nth order PIMD product by filtering the time delayed, upsampled downlink baseband modulated signal with a Nth order power series kernel; generating a nth filtered signal by subtracting the estimated Nth order PIMD product from the n−1th filtered signal; and downsampling the nth filtered signal.

Abstract: A signal power tester in provided. The signal power tester includes at least one interface to communicatively couple the signal power tester unit to a front-haul communication link used for communicating front-haul data to a remote radio head (RRH) having one or more antenna ports. The signal power tester further comprises a programmable processor, coupled to the interface, configured to execute software, wherein the software is operable to cause the signal power tester to do the following: determine a representative segment indicative of a noise floor of a communication signal; determine whether the representative segment meets selected criterion; determine a translation factor for the representative segment; and measure power of the communication signal based on applying the translation factor.

Abstract: A system and method for estimating a location of a wireless device receiving signals from plural nodes of a communications network. A wireless device may be directed to transmit a first signal having one or more predetermined parameters. At one or more location measurement units (“LMU”) an uplink time of arrival (“TOA”) measurement between the wireless device and one or more of the plural nodes or LMUs may be determined as a function of the first signal transmitted from the wireless device. Downlink signal measurements of signals received by the wireless device may be collected, and a location of the wireless device determined as a function of the uplink TOA measurements and the collected downlink signal measurements.
