Abstract: A system for channel access in Long Term Evolution (LTE) License-Assisted Access (LAA) is disclosed. The system includes a controller and a plurality of radio points. A level one radio point transmits a first reservation signal in response to a first backoff counter reaching zero. The first reservation signal indicates that the level one radio point will begin a first transmission of a first duration starting in a next subframe. A candidate level two radio point receives the first reservation signal and determines whether the candidate level two radio point received the first reservation signal with a signal to interference noise ratio (SINR) that exceeds a reservation detection threshold for the candidate level two radio point.

Abstract: A network includes an audio signal producing device, a content distributor communicatively coupled to the audio signal producing device, a router, a network communication medium communicatively coupling the content distributor and the router, and a plurality of addressable loudspeakers communicatively coupled to the network communication medium, wherein each of the addressable loudspeakers are configured to function as a network peripheral in the home network.
