Point Start up An Access Point unit starts and immediately begins transmitting periodic messages called beacons These beacon messages are messages contain information for Clients on how to establish a link with the Access Point Any Client that hears the messages which are not already linked to another Access Point unit will respond and links will be established between the new Access Point and these Clients Client Start up When a Client powers up 1t immediately scans for messages from Access Point units The Client will continue to scan for twice the configured beacon interval in the Client During the scan the RX led will flicker now and again indicating messages received perhaps from an Access Point If the Client finds suitable Access Points during the scan it will then attempt to establish a link with the Access Point with the strongest radio signal Link Establishment When the Client wishes to establish a link with an Access Point it follows a two step process The first step is authentication During this step the Client and Access Point check if they can establish a secure link based upon the configured security encryption Once the Client has been authenticated it will then request a link This step is called association While no links have been established the LINK led will be OFF Once a single link has been established the LINK led is ON After the link is established data may be transferre
