  • Page 15: 3. Wireless Topologies

    9 3. Wireless topologies rangelan2 products look and operate similar to ethernet products. The only difference is that a radio replaces the wire between various nodes. This means that all of your existing applications that operate over ethernet will work with rangelan2 without any special wireless n...

  • Page 16: Infrastructure

    10 infrastructure many companies have an existing ethernet or token ring lan infrastructure and want to be able to extend that capability to wireless nodes. This is accomplished by attaching an access point to the wired lan. This allows the wireless clients to access the network resources. Figure 4 ...
