The SSID Solution No AAA protocol implications No EAP or NAI interoperability issues Does require APs to support multiple SSIDs If the number of advertised networks is large, can consume a lot of beacon bandwidth At 1 mbps, all bandwidth used for 100 network advertisements! A similar issue with the EAP/scan solution, but not dependent on number of networks -- instead, the number of logins per second x number of APs However, in the EAP/scan solution a higher speed can be chosen for the unicast communications For instance, 10 logins per second with 10 APs and 100 networks, with 10 mbps unicast speed would result in 10 * 10 * 10000 = 1 mbps or 10% of the bandwidth used |
