Patent number: 10278138Abstract: Embodiments of the disclosure relate to selective multichannel amplification in a distributed communication system. In this regard, a remote antenna unit (RAU) in the distributed communication system receives downlink digital signals associated with downlink channels having respective downlink channel bandwidths. The RAU digitally scales the downlink digital signals based on respective digital scaling factors to generate scaled downlink digital signals having a substantially equal channel power density in the downlink channels. By digitally scaling the downlink digital signals to provide the substantially equal channel power density in the downlink channels, it is possible to provide substantially uniform radio frequency (RF) coverage range across the downlink channels, thus helping to improve overall RF coverage and user experience in a coverage area of the distributed communication system.Type: GrantFiled: March 14, 2018Date of Patent: April 30, 2019Assignee: Corning Optical CommunicationsInventor: Liav Moshe Daniel

Patent number: 10277323Abstract: Embodiments of the disclosure relate to combining uplink radio frequency (RF) communications signals in a remote unit in a wireless distribution system (WDS) using a differential mixer. A remote unit in a WDS receives a first uplink RF communications signal(s) and a second uplink RF communications signal(s). A differential mixer, which is typically configured to combine a pair of differential input signals, is controlled to combine the first uplink RF communications signal(s) and second uplink RF communications signal(s) without requiring the first uplink RF communications signal(s) and second uplink RF communications signal(s) to be converted into the pair of differential input signals. As a result, it may be possible to eliminate a signal combiner and a BalUn circuit from the remote unit, thus helping to save component costs and board space, and to reduce insertion loss and ripple to improve uplink signal quality in the remote unit.Type: GrantFiled: May 16, 2018Date of Patent: April 30, 2019Assignee: Corning Optical Communications LLCInventor: Dror Ben-Shlomo
