  • Forwarding data between an array of baseband units and an array of radio heads in a distributed wireless system using TDM switches
    Patent number: 10938600
    Abstract: The present disclosure discloses a distributed system. The distributed system includes a plurality of radio heads and a plurality of controllers disposed in one or more chassis external to the plurality of radio heads. Each of the plurality of controllers includes a baseband unit (BBU), an uplink time-division multiplexing (TDM) switch and a downlink TDM switch. The uplink TDM switch and the downlink TDM switch forward data bits between a radio head and a BBU by using TDM cells which may reduce latency relative to using Ethernet frames.
    Type: Grant
    Filed: January 30, 2019
    Date of Patent: March 2, 2021
    Assignee: Cisco Technology, Inc.
    Inventors: David S. Kloper, Brian D. Hart, Dipankar B. Acharya
