Publication number: 20110250854Abstract: A wireless transmission system supporting at least first and second high-isolation transmission modes. In the first TX mode, first and second incoming data streams are processed independently within first and second TX paths to generate first and second analog outgoing signals for separate transmission via first and second antennas. In the second TX mode, the two incoming data streams are combined to form a combined data stream. First and second versions of the combined data stream are processed by the first and second TX paths to generate two analog signals that are combined for transmission via a single antenna. In the second TX mode, a feedback signal, based on differences between the two analog signals, is used to adjust the relative phase and/or delay of the two versions of the combined signal in the digital domain to reduce phase differences between the two analog signals, thereby increasing signal transmission power.Type: ApplicationFiled: April 9, 2010Publication date: October 13, 2011Applicant: ANDREW LLCInventor: Simon Hamparian

Publication number: 20110201269Abstract: A method of monitoring an element in wireless communication system is provided. An operational noise measurement is obtained by measuring a noise value outside of a bandwidth of a first device, but within a bandwidth of a second, subsequent device. The operational noise measurement is alternatively obtained by tuning an input band of the element to shift the input band partially or completely outside of a bandwidth of a first device to create an open band or by suppressing an input of the antenna and measuring noise within the open bandwidth of the element of the wireless communication network. A stored parameter is retrieved and compared to the measured operational noise. Alternatively, a leakage signal of the element may be received at a signal receiver and compared to a reference. The reference is a function of components of the wireless communication system in a leakage path of the leakage signal.Type: ApplicationFiled: February 16, 2010Publication date: August 18, 2011Applicant: ANDREW LLCInventors: Neil T.
