Abstract: Aspects of a method and system for installation and configuration of a femtocell are provided. In this regard, information for configuring a femtocell to operate in a specified location may be received by the femtocell and may be utilized to configure one or more parameters of the femtocell. Once the femtocell is operational the parameters may be updated and/or optimized based on one or both of characterizations of cellular signals and/or information received from a femtocell registry. In this manner the femtocell may be reconfigured utilizing the updated and/or optimized parameters. The one or more parameters may be configured based on attributes of the location in which the femtocell is to operate. The one or more parameters may be configured based on a location, number, and/or coverage area of other femtocells The parameters may comprise one or more of power levels, frequency of operation, and/or antenna beam pattern.

Abstract: A wireless device includes processing circuitry, a receiver section, a transmitter section, and an antenna. The processing circuitry determines a set of information signals of a RF Multiple Frequency Bands Multiple Standards (MFBMS) signal. The receiver section down-converts a portion of the RF MFBMS signal by one or more respective shift frequencies to produce a corresponding baseband/low Intermediate Frequency (BB/IF) information signal from which the processing circuitry extracts data. The transmitter section converts a respective BB/IF information signal received from the processing circuitry by a respective shift frequency to produce a corresponding RF information signal and a combiner that combines the RF information signals to form a RF MFBMS signal. The receiver section and the transmitter section include ADCs and/or DACs, respectively, that are adjustable based upon characteristics of the RF MFBMS signal, the BB/IF MFBMS signal, and/or based upon signals carried therein, e.g., modulation type, SNR requirements, etc.

Abstract: In some aspects, the disclosure is directed to methods and systems for coexistence management. A first access point is scheduled a time to begin transmission of a packet to a user device in an unlicensed frequency band using a first RAT. The time to begin the transmission is scheduled to avoid transmission overlap with a second access point using a second RAT in the unlicensed frequency band, and scheduled according to information from the second access point regarding operation in the unlicensed frequency band using the second RAT. One of the first and second RATs includes one of a WLAN RAT or a LTE based RAT, and another of the first and second RATs includes a remaining one of the WLAN RAT or the LTE based RAT, in one or more embodiments. The first access point receives updated information regarding operation in the unlicensed frequency band using the second RAT. Using the updated information, an updated time for the first access point to begin the transmission using the first RAT is determined, the updated time determined to avoid transmission overlap with the second RAT in the unlicensed frequency band. The first access point transmits, according to the determined updated time, the packet in the unlicensed frequency band using the first RAT.
