Abstract

Aspects of the subject disclosure may include, for example, a communication node having a modem that receives first data streams from a source communication node via a first plurality of twisted pair transmission lines. A multiplexer selects a first subset of the first data streams and a second subset of the first data streams. A wireless transceiver wirelessly transmits the first subset of the first data streams as radio frequency signals via an antenna to at least one device. A distribution point unit transmits the second subset of the first data streams on a second plurality of twisted pair transmission lines to a destination communication node of a distributed antenna system.
