Various aspects of a method and system for indicating the link quality between wireless base station units are presented. The establishment of a wireless network involves the placement of and communication between several base station units. To facilitate the operational capability of such a wireless network, a method for continuously displaying the quality of the links between these base station units is introduced. The method provides each base station with the information necessary to individually display the quality of the links between itself and its neighboring base stations. The displays can take on a variety of formats. Additionally, link quality of neighboring base stations can be collected by a central controller which can process the information and create a grid showing the link quality throughout the wireless network. |

DETAILED DESCRIPTION A method for indicating the quality of the links between wireless base stations is described in detail below.
In the following description, numerous specific details are provided to provide a thorough understanding of, and enabling description for, embodiments of the invention.
One skilled in the relevant art, however, will recognize that the invention can be practiced without one or more of the specific details, or with other symbols, methods, etc.
In other instances, well-known structures or operations are not shown, or are not described in detail, to avoid obscuring aspects of the invention.
At the simplest level, wireless communication takes place between a mobile unit ("MU") and a base station unit ("BSU").
This communication can take place at will as the MU moves throughout a region defined by the coverage area of the BSU.
Coverage area is limited by environmental factors, technological limitations, structural characteristics, government regulations and the like.
To overcome these limitations, several BSU's with limited range can be combined to form a network often referred to as a local area network.
Arranging the BSU's in such a manner that their coverage: area overlaps allows a MU to extend its mobility by transferring, or handing off, its connectivity from one BSU to the next BSU.
For this to take place each BSU, or alternatively a central controller, must know what other base stations are within handoff range.
With this knowledge each base station can establish a station to station autonomous handoff without the necessity of a central system or network controller.
Station to station autonomous handoffs require each base station to detect and communicate with other BSU's.
In one embodiment of the claimed invention, the base station units ("BSUs") communicate with each other on a dedicated radio frequency or frequencies.
Base stations can thereby detect one another and autonomously determine a list of "neighboring base stations".
Each base station can then store the list of discovered neighboring base stations internally and update the list as conditions change
