AP to Wireless Clients Configuration

AP to Wireless Clients Configuration
The AP enables wireless clients to move from the coverage area of one AP into the
coverage area of another AP while maintaining LAN connectivity. This capability is
called roaming. Figure 1-2 illustrates a wireless client roaming from one AP coverage
area to another. Each coverage area is called a cell, where a cell is a single AP and its
wireless clients within a network of multiple APs.
Figure 1-2: Roaming
In Figure 1-2, Cell 1 and Cell 2 share overlapping areas of coverage. As a wireless
client moves from Cell 2 to Cell 1, the necessary network information is passed from
AP2 to AP1.
When a wireless client (such as the laptop computer in Figure 1-2) approaches the
boundary of a coverage area, the wireless client searches for a new AP that provides a
better quality signal, resulting in more reliable data throughput.
