• Black Box LW001A, 31 3-MBPS WIRELESS ETHERNET HUBS, ADAPTERS, AND BRIDGES Antennas Make sure the antennas are extended vertically in relation to the floor. Central Location Install the Hub in a central location in the coverage area you intend to include in the cell. Good positions are: • At the center of a large room. • At the center of a corridor. • At the intersections of two corridors. Many modern buildings have metallic partitions. We recommend that you install the Hubs in the corridor ceilings. The radio waves propagated by the Wireless Ethernet LAN may be reflected along the metal partitions and enter the offices through the doors or glass sections. Metal Furnitur

• Black Box LW001A, 95 3-MBPS WIRELESS ETHERNET HUBS, ADAPTERS, AND BRIDGES 5.1.5 WLAN P ARAMETERS 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-writ

• Black Box LW001A, 92 3-MBPS WIRELESS ETHERNET HUBS, ADAPTERS, AND BRIDGES All addresses may be set using regular IP address notation (four bytes separated by periods), together with the subnet mask. To access a host belonging to a different subnet, the Wireless Ethernet Hubs send the traffic through the default IP gateway. The gateway IP address should also be specified if such access is required. To set the Hub IP parameters: 1. From the System Configuration menu, type 2. The IP menu appears. 2. From the IP menu, select the requi
