Abstract: 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.

Abstract: Systems and methods for improved digital RF transport in a DAS are provided. In one embodiment, a transceiver comprises: a receive path circuit including an RF reception interface coupled to an ADC, the ADC receiving a down-converted analog RF spectrum from the RF reception interface and producing a digitized RF spectrum at an input sampling rate; a logic device receiving the digitized RF spectrum and producing a first set of baseband data samples at a first sampling rate, corresponding to a first spectral region of the analog RF spectrum and a second set of baseband data samples at a second sampling rate, corresponding to a second spectral region of the analog RF spectrum. The logic device maps the first set and second sets of baseband data samples to a respective first set and second set of timeslots of a serial data stream transport frame.
