Hopping Sequence

3-MBPS WIRELESS ETHERNET HUBS, ADAPTERS, AND BRIDGES

5.1.5WLAN PARAMETERS

The WLAN Parameters Menu contains the following sub-menus:

Hopping Sequence

The hopping sequence is a parameter that is set for the Hub. The stations learn it from the Hub at the association process.

Changing this parameter is useful when several Hubs are co-located. This reduces the probability of frame collision between co-located cells.

Range

The Hopping Sequence must be in the range between 1 and 22.

Default Value

The default value is 1.

Access Rights

This value is read-write on the Hub, and read-only on the stations.

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.
