3-MBPS WIRELESS ETHERNET HUBS, ADAPTERS, AND BRIDGES

Figure 4-21. Basic Wireless Ethernet Cell.

Once the Adapters establish association, you can communicate with all the other wireless stations in the cell and via the Hub’s Ethernet connection, with all the network facilities.

Once the Bridge establishes association, the Hub starts forwarding data packets to the wireless LANs connected to the Wireless Bridge.

IntroductionThe 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 3-MBPS WIRELESS ETHERNET HUBS, ADAPTERS, AND BRIDGES Figure 3-1.
