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.

Claims

1. A wireless communication system, said system comprising:

a first station comprising;

a first indoor unit comprising a first fiber optic interface and an Ethernet interface, wherein said Ethernet interface receives Ethernet signals from a local subscriber; and

a first fiber optic cable providing digital communication of subscriber data received from said local subscriber via said first Ethernet interface between said first indoor unit and a first outdoor unit comprising a second fiber optic interface and a wireless interface;

wherein said first outdoor unit transmits information comprising routing or switching information to a second outdoor unit located at a second station.

2. The wireless communication system of claim 1 wherein said first outdoor unit receives data comprising routing or switching information from said second outdoor unit located at said second station.

3. The station of claim 1 wherein data received at said wireless interface is transmitted to said local subscriber via said Ethernet interface.

4. The station of claim 1 wherein said Ethernet interface links said first station to a network backbone via an Ethernet link.

5. A wireless communication system comprising:

a first station comprising;

a first outdoor unit comprising a wireless interface and a first fiber optic interface; and

a fiber optic cable between said first outdoor unit and a first indoor unit comprising a second fiber optic interface and an Ethernet interface that receives Ethernet signals from a local subscriber;

wherein said fiber optic cable provides digital communication of subscriber data received from said local subscriber via said Ethernet interface between said first indoor unit and said first outdoor unit;

wherein said first outdoor unit transmits information comprising routing or switching information to a second outdoor unit located at a second station.

6. The wireless communication system of claim 5 wherein said firs outdoor unit receives data comprising routing or switching information from said second outdoor unit located at said second station.

7. The station of claim 5 wherein data received at said wireless interface is transmitted to said local subscriber via said Ethernet interface.

8. The station of claim 5 wherein said Ethernet interface links said first station to a network backbone via an Ethernet link.
