Mobile people with mobile computers need mobile networks. Advances in basic radio technologies, very large scale integrated (VLSI) circuit technology (lower power consumption, lower cost and smaller form factors) and other radio components, network and wireless protocols, standards, reliability, security, management and, of course, total cost of ownership (TCO) have yielded sophisticated, capable, high-performance, and broadly-applied WLAN technologies and systems of today. These advances have remarkable end-user demand that continues to accelerate even today. We have thus moved to the wireless LAN as primary or default access in all key venues – businesses and organizations of all forms, the residence and public spaces. And, of course, such connectivity is more than appropriate for all applications and all forms of traffic, including time-bounded voice telephony and streaming video. The key challenge
to date has been increasing both capacity and coverage as users demand ever-higher
levels of service with an ever-growing arsenal of wireless devices. Find out how by downloading this paper.

802.11ac, the emerging standard from the IEEE, is like the movie The Godfather Part II. It takes something great and makes it even better. 802.11ac is a faster and more scalable version of 802.11n. 802.11ac couples the freedom of wireless with the capabilities of Gigabit Ethernet. Wireless LAN sites will see significant improvements in the number of clients supported by an access point (AP), a better experience for each client, and more available bandwidth for a higher number of parallel video streams. Even when the network is not fully loaded, users see a benefit: their file downloads and email sync happen at low lag gigabit speeds. Also, device battery life is extended, since the device’s Wi-Fi interface can wake up, exchange data with its AP, then revert to dozing that much more quickly. This paper provides a technical description of the next generation of Wi-Fi.
