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 ...

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 ...

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 ...

在Wi-Fi技术演进的20年时间里，无线技术的发展速度已经超出了所有人的预料。而得益于智能手机等移动终端的全面普及，人们对Wi-Fi的需求也越来越高，即便是影响广泛的802.11n，似乎也正从主流电子设备的标配中消失。那么距离802.11n的全面终结还有多久时间呢？

When 802.11b first started getting popular in late 2000, no one imagined that it would still be the most dominant standard 6 years later and continue to dictate the design of the latest wireless LAN ...

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 ...

The 802.11 designation refers to the IEEE’s WLAN standard, commonly called by its trade name, Wi-Fi. The suffix indicates one alternative of the standard. Currently, 802.11n is the most widely ...

My normal network is Wifi 5, but I have 802.11n enabled on the guest network. The guest network runs on the same APs as my main network. I have 3 APs controlled by a controller. I might occasionally ...

Faster Wi-Fi: It's something we all crave. Fortunately, it's also something we can have, even on a budget. It's not just about fast Internet speeds to and from your service provider. It's also about ...
