System Conﬁgurations

The Aironet 4000 Series Wireless LAN Adapter can be used in a variety of network system conﬁgurations. Aironet Access Points (AP4500 or AP4800) provide connections to your Ethernet or Token Ring networks or act as repeaters increasing wireless communication range. The maximum communication range is based on how you conﬁgure your wireless infrastructure.

Examples of some common system conﬁgurations are shown on the pages that follow, along with a description of each.
