Abstract: The subject matter discloses a tower mount amplifier device (TMA device), comprising a reception circulator for receiving a reception signal transmitted from an antenna to a base station and a low noise amplifier unit for amplifying the reception signal. The TMA device also comprises a band pass filter for filtering the reception signal amplified by the low noise amplifier unit and a transmission circulator for transmitting the reception signal filtered by the band pass filter to the base station. In some cases, the tower mount amplifier further comprises a switch for switching the signal from the reception circulator directly to the transmission circulator, wherein the switch operates according to a functionality of the low noise amplifier unit.

Abstract: A noise reduction system in a wireless communication network, including: two or more input antennas adapted to receive wireless signals; wherein each input antenna has a different receiving characteristic, so that the signals provided by the input antennas constitute a distinct combination of the received signals; a filter coupled to each of the input antennas except one, wherein the filter is adapted to estimate the correlation between the signal provided by its associated input antenna and the signal provided by the input antenna not coupled to a filter and mitigate a dominant component of the received signals responsive to the estimation; a summator that is adapted to combine the filtered signal and the signal provided by the input antenna not coupled to a filter and provide the result as feedback to the filter; and wherein the filtered signals from all the filters are combined to form an output signal.

Abstract: An apparatus and method for Repeater-based cellular coverage switching across cellular donor sites in a wireless network is disclosed. The method involves measuring capacity load levels of cellular donor sites, determining cellular switching schemed based on the capacity loads establishing cellular switching configurations based on the cellular switching schemes, and performing cellular coverage switching to cellular donor sits.
