Patent number: 11750280Abstract: In one embodiment, an over-the-air millimeter wave repeater for a communications network comprises: a donor unit including a first plurality of modular electronic components and an access point including a second plurality of modular electronic components. The donor unit communicates downlink mmWave spectrum wireless signals received from a base station to the access point and radiates uplink mmWave spectrum wireless signals received from the access point to the base station. The access point radiates the downlink mmWave spectrum wireless signals received from the donor unit into a coverage area, receives the uplink mmWave spectrum wireless signals received from the coverage area, and communicates the uplink mmWave spectrum wireless signals to the donor unit. The first and second plurality of modular electronic components includes at least one of a modular antenna component, a modular signal conditioning component, a modular signal interface component, and a modular controller.Type: GrantFiled: February 4, 2021Date of Patent: September 5, 2023Assignee: COMMSCOPE TECHNOLOGIES LLCInventors: Daniel Schwab, Felix Lübbers, Joerg Stefanik, Patrick Braun, Thomas Kummetz, Alfons Dussmann, Klaus Uwe Rosenschild, Ahmed H.

Patent number: 11646702Abstract: Techniques are provided to more accurately determine reflected power, reflection coefficient, and/or voltage standing wave to permit prompt protection of components such as power amplifiers and notify communication system operators. This is accomplished by more accurately determining an amplitude and phase of an output reflected signal at an output port of a bidirectional coupler as a function of the following: an amplitude and a phase of a coupled forward signal coupled into a forward coupled port of the bidirectional coupler; an amplitude and a phase of a coupled reverse signal coupled into a reverse coupled port of the bidirectional coupler; an electrical transmission parameter from an input port of the bidirectional coupler to the forward coupled port; an electrical transmission parameter from the input port to the reverse coupled port; and an electrical transmission parameter from an output port of the bidirectional coupler to the reverse coupled port.Type: GrantFiled: June 17, 2021Date of Patent: May 9, 2023Assignee: Andrew Wireless Systems GmbHInventors: Peter Gunzner, Johannes Steigert, Felix Lübbers, Peter Schmid, Patrick Braun

Patent number: 11277211Abstract: A method comprises: measuring reflected and forward power at a power amplifier output; determining if the reflected power equals to or exceeds a first level; if the reflected power is equal to or exceeds the first level, then reduce power of a power amplifier input signal; determining if a standing wave ratio at the power amplifier output equals or exceeds a second level; if the standing wave ratio at the power amplifier output equals or exceeds the second level, then reducing the power amplifier input signal power level and/or sending an alarm; determining if the power amplifier output power equals or exceeds a third level; and if the power output from the power amplifier equals or exceeds the third level, then reducing the power amplifier input signal power level until such power level is less than or equal to the third level and/or sending an alarm.Type: GrantFiled: August 5, 2019Date of Patent: March 15, 2022Assignee: Andrew Wireless Systems GmbHInventors: Felix Lübbers, Rainer Friedrich
