Abstract

A system for networking Wi-Fi Access Points in a Distributed Antenna System includes a plurality of Digital Access Units (DAUs). The plurality of DAUs are coupled and operable to route signals between the plurality of DAUs. The system also includes a plurality of Digital Remote Units (DRUs) coupled to the plurality of DAUs and operable to transport signals between DRUs and DAUs and a plurality of DAU ports and DRU ports. The system further includes a Framer/Deframer, wherein the cellular payload data is separated from the IP data and a network switch. The IP data from a plurality of DAU and DRU ports are buffered and routed to a plurality of DAU and DRU ports. Furthermore, the system includes a plurality of Wi-Fi access points coupled via a mesh network to Wi-Fi access points connected to a plurality of DRUs.

Claims

1. A system for networking Wi-Fi Access Points in a Distributed Antenna System, the system comprising:

a plurality of Digital Access Units (DAUs), wherein the plurality of DAUs are coupled and operable to route signals between the plurality of DAUs;

a plurality of Digital Remote Units (DRUs) coupled to the plurality of DAUs and operable to transport signals between DRUs and DAUs;

a plurality of DAU ports and DRU ports;

a Framer/Deframer, wherein the cellular payload data is separated from the IP data;

a network switch, wherein the IP data from a plurality of DAU and DRU ports are buffered and routed to a plurality of DAU and DRU ports; and

a plurality of Wi-Fi access points coupled via a mesh network to Wi-Fi access points connected to a plurality of DRUs.

2. The system of claim 1 wherein the plurality of DAUs are coupled via at least one of Ethernet cable, Optical Fiber, Microwave Line of Sight Link, Wireless Link, or Satellite Link.

3. The system of claim 1 wherein the plurality of DAUs are coupled to the plurality of DRUs via at least one of Ethernet cable, Optical Fiber, Microwave Line of Sight Link, Wireless Link, or Satellite Link.

4. The system of claim 1 wherein the DRUs are connected in a daisy chain configuration.

5. The system of claim 1 wherein the DRUs are connected to the DAUs in a star configuration.

6. The system of claim 1 wherein the DRUs are connected in a loop to a plurality of DAUs.

7. The system of claim 1 wherein the DAU and DRU ports for the Network Switch are a plurality of either optical, router, Ethernet, or microprocessor ports.

8. The system of claim 1 wherein the Wi-Fi Access Points are integrated into the DRUs.
