IMPACT OF NEXT GENERATION WIRELESS LAN ON LEGACY DEVICES

The next generation wireless LAN Technology which offers new challenges and opportunities called 802.11n is a set of IEEE standard specification. It promises for designing and delivering data on wireless networking that is four to six times faster than earlier 802.11a/g (legacy WLAN devices) networks and improve transmission range. It has been proven that the 802.11n technology having wide bandwidth channel that satisfy next generation application and maintaining backward compatibility with previous generations of hardware by making two comparison. The first comparison has been made between different Legacy Devices on 802.11n to show throughputs of these devices. The second comparison has been made between the rate and range to evaluate the effect of higher rate on both sides of the link. The next-generation WLAN would also need to provide native support for wireless voice and video, with high levels of accessibility, availability, and security to reduce service-impacting incidents.
