EVOLVED DISTRIBUTED ANTENNA SYSTEM
First Claim
1. A distributed antenna system (DAS) comprising:
- a host unit; and
a plurality of remote units communicatively coupled to the host unit;
wherein the host unit comprises;
a plurality of base transceiver stations; and
a switch;
wherein each of the base transceiver station is configured to operate on a radio frequency (RF) channel and wherein each of the base transceiver stations is configured to provide a downstream baseband digital signal to the switch and to receive an upstream baseband digital signal from the switch, wherein each downstream baseband digital signal and upstream baseband digital signal is a digital representation of the RF channel at baseband of the respective base transceiver station;

Abstract
One embodiment is directed to a distributed antenna system (DAS) including a host unit and a plurality of remote units. The host unit includes a plurality of base transceiver stations and a switch. Each of the base transceiver stations is configured to provide a downstream baseband digital signal to the switch and to receive an upstream baseband digital signal from the switch, wherein each downstream baseband digital signal and upstream baseband digital signal is a digital representation of the RF channel at baseband of the respective base transceiver station. The switch is configured to route each of the downstream baseband digital signals to a respective subset of the remote units as one or more downstream serial data streams and to route each of the upstream baseband digital signals from one or more upstream serial data streams to a respective subset of the base transceiver stations.

26. A method for generating and distributing wireless RF signals at a host unit in a distributed antenna system comprising the host unit which is communicatively coupled to a plurality of remote units, the method comprising:
-
receiving Internet Protocol (IP) data at the host unit, from an IP network entity, wherein the IP data corresponds to a radio frequency (RF) signal; routing the IP data to a respective base transceiver station within the host unit; at the host unit, baseband processing the IP data at each base transceiver station such that each base transceiver station generates a digital representation of an RF signal for transmission from a remote unit to a wireless device, wherein the digital representation of the RF signal is at baseband; at the host unit, multiplexing the digital representations of an RF signal together to form a serial data stream; and sending the serial data stream from the host unit to one or more of the remote units. - View Dependent Claims (27, 28, 29)
