Power management in distributed antenna systems (DASs), and related components, systems, and methods
Patent number: 9497706Abstract: Power management in a distributed communications system, such as a distributed antenna system (DAS), that includes determining user activity at remote units of the DAS. When user activity in one or more remote units falls below or above a specified threshold, power usage by the one or more remote units is reduced or increased accordingly. The power usage may reduced and/or increased by turning select remote units on or off, by increasing or reducing an operating voltage of one or more power amplifiers, and/or by turning select multiple-in, multiple-out (MIMO) front ends on or off. Power may be reduced such that wireless coverage within a specified area is maintained.Type: GrantFiled: February 20, 2013Date of Patent: November 15, 2016Assignee: Corning Optical Communications Wireless LtdInventors: Nissim Atias, Isaac Shapira -

Patent number: 9131511Abstract: Backoff snooze wake power consumption within single user, multiple user, multiple access, and/or MIMO wireless communications. If a communication (e.g., transmission) attempt fails (e.g., by a wireless station (STA), smart meter station (SMSTA), etc.), then a backoff snooze countdown may be performed before a subsequent communication is attempted. Also, if communication activity is detected on the communication medium, then such a backoff snooze countdown may be performed before monitoring the communication medium or a subsequent communication attempt is made. Such a backoff snooze countdown may be based on a codeword value (e.g., such as provided within a beacon received from an access point (AP)), and different respective backoff snooze countdowns may be made based on different respective codeword values. Such backoff snooze countdowns are performed outside of a restricted access window (RAW) in which only devices of a particular class (e.g., low-power, Z, etc.) have access to the communication medium.Type: GrantFiled: January 11, 2013Date of Patent: September 8, 2015Assignee: Broadcom CorporationInventor: Matthew James Fischer
