Wireless communication subsystem with a digital interface
First Claim
1. A wireless communication method, the method comprising:
- receiving, at an indoor unit at a subscriber location, first data over a first broadband digital interface, the first broadband digital interface comprising a fiber optic cable from a first outdoor unit located at a first location that receives first wireless signals and performs analog signal processing associated with the received first wireless signals;
performing, at the indoor unit, digital signal processing on the received first data;
transmitting, from the indoor unit, first subscriber data comprising Ethernet data over at least one Ethernet interface to at least one of a plurality of first local subscribers;
receiving, at the indoor unit, second data over a second broadband digital interface, the second broadband digital interface comprising a fiber optic cable from a second outdoor unit located at a second location that receives second wireless signals and performs analog signal processing associated with the second received wireless signals;
performing, at the indoor unit, digital signal processing on the received second data; and
transmitting, from the indoor unit, second subscriber data comprising Ethernet data over the at least one Ethernet interface to at least another of a plurality of second local subscribers;
where the first outdoor unit is adapted to transmit and receive first digital subscriber data over the first broadband digital interface and the second outdoor unit is adapted to transmit and receive second digital subscriber data over the second broadband digital interface with the indoor unit;
where the first outdoor unit transmits information comprising routing or switching information to the second outdoor unit.

Abstract
Systems and methods are disclosed which provide wireless communication systems implementing subsystems adapted for flexible deployment configurations and to resist the introduction of interference. Preferred embodiments of the present invention provide a wireless communication system configuration in which an ODU subsystem is coupled to an IDU subsystem using a fiber optic link. According to a preferred embodiment of the present invention, an ODU subsystem is adapted to provide conversion between digital and analog to thereby facilitate the use of a digital link between the ODU subsystem and a corresponding IDU subsystem. Embodiments of the present invention utilize a plurality of ODU subsystems configured according to the present invention to provide wireless communication coverage of a service area, such as to provide a wireless application termination system (WATS) hub for use in providing wireless communication links with respect to a plurality of subscriber units.
