4.6 Setting up Overlapping Wireless Ethernet Cells

3-MBPS WIRELESS ETHERNET HUBS, ADAPTERS, AND BRIDGES

Suggested maximum distance between Hub and workstation: 1000 m (3200 ft.)

With high-gain antennas: 1500 m (5000 ft.)

5.Obstructed Outdoor Areas—Outdoor areas with obstructed line-of-sight between the Hub and the Wireless Ethernet workstation.

Suggested maximum distance between Hub and workstation: 500 m (1600 ft.)

With high-gain antennas: 800 m (2500 ft.)

4.6 Setting up Overlapping Wireless Ethernet Cells

When two adjacent Hubs are positioned close enough to each other, a wireless Ethernet part of the coverage area of Hub #1 will overlap the coverage area of Hub #2. This overlap area has two important attributes:

1.Any workstation situated in the overlapping area can communicate with both Hub #1 and Hub #2.

2.Any workstation can move seamlessly between the overlapping coverage areas without losing its network connection. This attribute is called Seamless Roaming.

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.
