The IEEE 802.11h standard provides an addition 11 channels to the 802.11a standard's 12 non-overlapping channel for a total of 23 non-overlapping channels.

The IEEE 802.11b standard provides the lowest data rate at 1Mbps, but it also has the longest distance, which is about 350 feet.

The IEEE 802.11b standard provides 3 non-overlapping channels.

The IEEE 802.11g standard provides a maximum data rate of up to 54Mbps.

The split-MAC architecture allows the splitting of 802.11 protocol packets between the Cisco LWAPP-based AP, which handles real-time portions of the protocol, and the WLAN controller, which handles those items that are not time sensitive.

Extended Service Set ID means that you have more than one access point and they all are set to the same SSID and all are connected together in the same VLAN or distribution system so users can roam.

The IEEE 802.11g standard provides a maximum data rate of up to 54Mbps, but you need to be close to the access point, somewhere around 90 to 100 feet.

The IEEE 802.11b standard provides a maximum data rate of up to 11Mbps.

The Cisco Unified Wireless Solution is a great product, but you must purchase specialized devices. Cisco managed access points and a controller are the devices you need to purchase to run the Unified Wireless Solution.

The IEEE 802.11a standard runs in the 5GHz RF range.
