WDS (Wireless Distribution System) is the best way how to interconnect many access points and allow users to move around without getting disconnected from network. Using this system you can cover large areas and allow users to move for large distances while still being on-line. This system allows packets to pass from one wireless AP (Access Point) to another, just as if the APs were ports on a wired Ethernet switch. APs must use the same standard (802.11a, 802.11b or 802.11g) and work on the same frequencies in order to connect to each other.
