Systems and methods for IP communication over a distributed antenna system transport

摘要

Systems and methods for IP communication over a distributed antenna system transport are provided. In one embodiment, a method for providing Ethernet connectivity over a distributed antenna system comprises receiving internet protocol (IP) formatted data from an internet protocol device coupled to a remote unit of a distributed antenna system; sampling wireless radio frequency (RF) signals received at the remote unit to produce digitized RF samples; generating a serial data stream for output to a host unit of the distributed antenna system, the serial data stream further comprising a multiple-timeslot communication frame providing a first partition of bandwidth for transporting the digitized RF samples and a second partition of bandwidth for implementing an Ethernet pipe for transporting the IP formatted data.

主权项

1. A distributed antenna system, the system comprising:
a host unit; at least one remote unit for wirelessly communicating with one or more subscriber units, the at least one remote unit coupled to the host unit over a point-to-point communication link, wherein the at least one remote unit receives uplink radio frequency signals from the one or more subscriber units and samples the uplink radio frequency signals to generate digitized radio frequency signals, the at least one remote unit further comprising an Ethernet interface for receiving Internet Protocol formatted data; and an internet protocol device coupled to the Ethernet interface; wherein the at least one remote unit outputs a serial data stream to the host unit, the serial data stream including digitized radio frequency signals corresponding to distinct spectral regions of analog radio frequency spectrum and an Ethernet pipe for transporting the Internet Protocol formatted data received via the Ethernet interface; wherein the serial data stream comprises a multiple-timeslot communication frame, the digitized radio frequency signals including first bits within a timeslot of the multiple-timeslot communication frame and the Ethernet pipe including second bits within the timeslot.
