Enhanced Channel Scanning Schemes for Next Generation WLAN System

Free registration required

Executive Summary

The IEEE 802.11 standard based Wireless Local Area Networks (WLANs) are widely deployed and have gained greater popularity. It is anticipated that WLAN will play an important rule in the future wireless communication systems in order to provide several gigabits data rate. However, it has been a challenging problem to support the IEEE 802.11 WLAN devices to fully exploit the high throughput gains offered by the IEEE 802.11 standard whenever possible since the current channel scanning mechanisms in standard may result in unacceptable delay for network discovery.
