4.8 Associating with Other Hubs

3-MBPS WIRELESS ETHERNET HUBS, ADAPTERS, AND BRIDGES

4.8 Associating with Other Hubs

When two or more adjacent Hubs are positioned close enough to each other, a part of the coverage area of the Hubs will overlap. In high-traffic-density areas, Hubs are sometimes positioned so that all of their coverage areas overlap. A workstation situated in an overlapping coverage area can associate with any one of the covering Hubs.

The process of selecting with which Hub to associate is performed automatically by the Adapter. However, if your workstation is located within the coverage area of more than one Hub and your reception quality is low, you may get better reception if you move your station to a slightly different location. This takes advantage of a clearer or less busy connection to another Hub.

Introduction 3.1 The 3-Mbps Wireless Ethernet Product LineThe LW001A and LW007A function exactly the same way, but the LW001A has permanently attached antennas, and the LW007A has detachable antennas. A third Hub, LW005A which is covered in a separate manual, has the same hardware as the LW007A, but different software. It works with portable computers equipped with the PCMCIA Wireless Adapter LW006A to connect to wired Ethernet LANs Figure 3-1.
