Abstract: Aspects of a method and system for mitigating interference among femtocells via intelligent channel selection are provided. In this regard, signals which may interfere with cellular communications between a femtocell and a cellular communication device may be detected via the femtocell. Based on the detection, the femtocell may be configured to transmit and/or receive signals on one or more frequencies and/or channels. The one or more frequencies and/or channels may be determined in the femtocell and/or in a network management entity. Detecting interfering signals and configuring the one or more femtocells may occur periodically, upon installation of a femtocell, upon power-up of a femtocell, and/or upon command from a network administrator. The results of the detection may be communicated to one or more other femtocells and/or to a network management entity.

Abstract: Aspects of a method and system for controlling data distribution via cellular communications with an integrated femtocell and set-top-box (IFSTB) device are provided. In this regard, a cellular enabled communication device may detect when it is within cellular communication range of a femtocell. Upon detection of the femtocell, the cellular enabled communication device may communicate instructions to a content source instructing the content source to deliver multimedia content to the femtocell. In instances that multimedia content is already being delivered to the cellular enabled communication device prior to the detection, the instructions from the cellular enabled communication device may instruct the content source to redirect the multimedia content to the femtocell. In this regard, the multimedia content may be delivered from the content source to the cellular enabled communication device via the femtocell. The femtocell may deliver at least a portion of the multimedia content to other communication devices.

Abstract: Upstream frequency response measurement and characterization. Signaling is provided between respective communication devices within a communication system. Based upon at least one of these signals, one of the communication devices captures a number of sample sets corresponding thereto at different respective frequencies (e.g., a different respective center frequencies, frequency bands, etc.). Then, spectral analysis is performed with respect to each of the sample sets to generate a respective and corresponding channel response estimate there from. After this number of channel response estimates is determined, they are combined or splice together to generate a full channel response estimate. In implementations including an equalizer, different respective sample sets may correspond to those that have undergone equalization processing and those that have not.
