Wireless communication subsystem with a digital interface
First Claim
1. A wireless communication method comprising:
- providing a first outdoor unit comprising a first wireless interface and a first broadband digital interface to communicate subscriber data, wherein the first outdoor unit performs analog signal processing associated with a wireless communication system;
providing a second outdoor unit comprising a second wireless interface and a second broadband digital interface to communicate subscriber data, wherein the second outdoor unit performs analog signal processing associated with the wireless communication system;
configuring the first and second outdoor units to communicate received signals to an indoor unit over a first and second broadband digital link for digital signal processing; and
where the first outdoor unit is adapted to transmit and receive digital subscriber data between said first broadband digital interface of the first outdoor unit and a first interface of the indoor unit and the second outdoor unit is adapted to transmit and receive digital subscriber data between said second broadband digital interface of the second outdoor unit and the first interface of the indoor 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.
