Components Needed To Expand A Wireless Network
Once the basis of a wireless network has been installed it is easy to expand
the network to cover a wider range or to implement a separate wireless
network alongside the existing one. All that is required is another Wi-Fi
certified wireless access point (such as the 3Com Access Point 2000), and
Ethernet access to the wired network. If the network is being expanded from a
wireless gateway then this can be achieved by connecting the new access
point into the built-in switch incorporated into the gateway. If the network is
being expanded from an access point then this can be achieved by
connecting the new access point into the existing network, or by purchasing a
switch or hub to connect the access points.
This is all the networking equipment that is required. Wireless NICs will be
needed if there are new clients that are being added to the wireless network.

A wireless network can be extended simply by adding another access point to
your LAN and by configuring the new access point with the same ESSID or
Service Area Name, and WEP security settings as the first access point or
gateway. The access points should be placed so that the wireless ranges are
just overlapping – allowing roaming between the two This will enable wireless
users to roam between the two access points with no break in connection.
To calculate where to position the new access point it is necessary to know
the range of the both access points and therefore where the overlap occurs.
