Wireless Network Standards 802.11A 802.11a operates at the 5 GHz band and supports data rates at up to 54 Mbps. For those organizations demanding even higher speeds, a "turbo mode" feature can boost throughput rates up to 108 Mbps. And because there are fewer devices in the 5 GHz band, there's less potential for RF interference. However, because it is at an entirely different radio spectrum, it is not compatible with 802.11g. The higher spectrum provides about 50 meters (164 feet) of coverage-about half what 802.11g offers. Consider 802.11a when you need high throughput in a confined space and you are: „ Running high-bandwidth applications like voice, video, or multimedia over a wireless network that can benefit from a fivefold increase in data throughput „ Transferring large files like computer aided design files, preprint publishing documents or graphics files, such as MRI scans for medical applications, that demand additional bandwidth „ Supporting a dense user base confined to a small coverage area. Because 802.11a has a greater number of non-overlapping channels, you can pack more access points in a tighter space.
