+With Cisco’s UWN Split-MAC operation, the control and data messages are split. Lightweight Access Points (LWAP) communicate with the WLCs using control messages over the wired network. LWAPP data messages are encapsulated and forwarded to and from wireless clients. The WLC manages multiple APs, providing configuration information and firmware updates as

 ISM - Industrial, Scientific and medical - frequencies are set aside by ITU-R radio regulations 5.138 and 5.150. In the U.S., the Federal Communications Commission (15.247) specifies the ISM bands for unlicensed use. Several bands are specified in the following ranges:
 *900 to 928 MHz

 *5.75 to 5.875 GHz
 Of these, channels located in the 2.4-GHz range are used for 802.11b and 802.11g. As shown in Figure 1, 11 overlapping channels are available for use. Each channel is 22 MHz wide. It is common to use channels 1, 6, and 11 in the same areas, because these three channels do not overlap.
 === UNII ===
 The UNII - Unlicensed National Information Infrastructure - radio bands were specified for use with 802.11a wireless. UNII operates over three ranges:
