(Editor's note: This popular feature article, which was first published May 2007, is being republished in response to its great popularity and the likelihood that the 802.11n spec will be ratified in ...

The antennas used by wireless devices have a major impact on WLAN coverage, security and performance. This becomes increasingly evident in new draft 802.11n access points (APs), which use multiple ...

802.11n is expected to be ratified later this year and to provide speeds of up to 600 Mbps, which is over ten times faster than the existing standards. 802.11n also has other benefits such as ...

In theory, 802.11n can zip by your 100Mbps Fast Ethernet at a real-world 160Mbps, but the practice it’s usually much slower. No, the Wi-FI vendors aren’t lying; the problem is that you have to set 802 ...

IEEE 802 is a collection of networking standards that cover the physical and data link layer specifications for technologies such as Ethernet and wireless. These specifications apply to local area ...

Given a choice between fast, 802.11b; faster, 802.11g; and fastest, 802.11n, most people will pick the fastest every time. But, while the IEEE 802.11n Wi-Fi standard, with its up to 300Mbps burst ...

Illustration: Mick Wiggins What a difference a couple of years makes. In our first roundup of draft-802.11n Wi-Fi routers (see “Wireless Routers: The Truth About Superfast Draft-N“), we found so many ...

The MacWorld keynotes given this past January will probably go down in history for the announcement of the iPhone, but lost in the signal of that announcement was the launch of a very important ...

Like lets say under "ideal" conditions, the 802.11n is transferring at 300Mbps. If a router is rated 900 for that band (5Ghz), does this mean there is still 600Mbps available for ac connections? Or ...

Backward compatibility with the legacy devices (IEEE 802.11b/g) The typical 802.11n network consists of legacy 802.11b/g enabled systems and new 802.11n enabled MIMO-OFDM systems. The channel access ...

Wi-Fi's biggest advantage is that it provides mobility and coverage. But early versions of Wi-Fi did not achieve data rates on par with the wireline network. Recent advancements in wireless research ...
