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 ...

随着无线多媒体设备的普及以及高带宽应用需求的增加，WLAN必须具有更高的数据率。802.11n基于MIMO空中接口技术，覆盖范围扩大2倍，性能提升5倍，改变了Wi-Fi配置和使用方式，支持更大的海量数据应用，包括视频。从性能指标上看，802.11n已然成为下一代主流 ...

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 ...

OFDM调制技术是将高速率的数据流调制成多个较低速率的子数据流，再通过已划分为多个子载体的物理信道进行通讯，从而减少ISI（码间干扰）机会。 MIMO（多入多出）技术是在链路的发送端和接收端都采用多副天线，将多径传播变为有利因素，从而在不增加信道 ...

WiFi网络发展至今，已经可以说是达到了一个非常不错的水准。今天在市面上能见到的先进无线局域网设备普遍都能支持802.11n标准，达到300Mbps的无线传输速率对我们来说已经是非常简单的事情。 我们知道，11n标准最高可支持高达600Mbps的无线传输速率，也就是说 ...

曾经有很多朋友问我，他们在买无线路由的时候，都会看到有关于802.11a、802.11b、802.11g等一些标示，虽然知道这是有关无线路由传输速率的协议，但是对于这些协议却鲜有了解。尤其是今年又将是11n转正的关键时期，所以今天我们就从最初开始，慢慢的来了解 ...
