Patent number: 10785827Abstract: A master unit and a remote unit is provided for a multiband transmission system for distributing and combining signals of at least one wireless communication network and at least one digital network. A reference frequency generator is arranged in the master unit, the reference frequency generator being designed to clock a master modem for converting the signals of the at least one digital network. The reference frequency signal emitted by the reference frequency signal is restored via a reference frequency receiver and is used for closing a remote modem that is located there for demodulation.Type: GrantFiled: October 26, 2018Date of Patent: September 22, 2020Assignee: Andrew Wireless Systems GmbHInventors: Oliver Braz, Stefan Eisenwinter, Mathias A.

Patent number: 10623340Abstract: Certain features relate to improving the link-fault tolerance in a distributed antenna system (DAS) by utilizing a series of synchronous communication frames. A receiving remote unit or a head-end unit in the DAS can predict the start of incoming communication frames based on frame information extracted from previously received communication frames. For example, a remote unit can be configured to receive one or more communication frames, each of the one or more communication frames including a start-of-frame field. After a period of time corresponding to the frame repetition rate, the remote unit can search for an additional start-of-frame field, indicating the receipt of the next communication frame. The remote unit can extract the payload data from the next communication frame based on the predicted value for the additional start-of-frame field.Type: GrantFiled: March 26, 2018Date of Patent: April 14, 2020Assignee: CommScope Technologies LLCInventors: Christopher Goodman Ranson, Mathias A. Schmalisch, Van E. Hanson

Patent number: 10251154Abstract: Certain features relate to configuring a remote unit in a distributed antenna system (DAS) to switch between a baseband mode of operation and a measurement receiver mode of operation. In the baseband mode of operation, the remote unit can transmit a subset of baseband channels to a head-end unit or an extension unit of the DAS. The subset of baseband channels can carry wireless communication information. In the measurement receiver mode, the remote unit can transmit wideband data to the head-end unit or the extension unit of the DAS. The wideband data can include one or more of a measurement data for additional baseband channels other than the subset of baseband channels and information for use by the head-end unit to modify a configuration of the distributed antenna system.Type: GrantFiled: February 12, 2015Date of Patent: April 2, 2019Assignee: CommScope Technologies LLCInventors: Christopher Goodman Ranson, Mathias Schmalisch
