802.11n的优势（Advantages of 802.11n） The advantage of 802.11n 802.11n has the incomparable advantage of other protocols. Technology advantage The advantage of 11N technology is mainly reflected in the transmission speed and signal range, the transmission rate of 802.11N due to MIMO (multiple input multiple output) and OFDM (orthogonal frequency division multiplexing) technology to greatly enhance the transmission rate was got. In the scope of coverage, 802.11n using smart antenna technology, antenna array with multiple independent antenna components, can dynamically adjust the beam, ensure that WLAN users receive stable signal, and can reduce the interference from other signals, which greatly enhance the mobility of WLAN. Application: high quality speech. We know that as long as the mobile phone support WI-FI download software can make Internet phone calls, but due to the speed limit on the wireless router call quality is not ideal. But the 802.11N wireless router can be a very good solution to this problem, 11N theories that the speed of 300Mbps, but from the actual use and test, in the normal environment (signal interference and some barrier) transmission speed of most 11N products are 100%, but even at this speed also means that people can with the Wi-Fi mobile phone to dial the IP telephone in the office, but also enjoy higher quality voice calls. Application: two HD video transmission HD video 802.11N product is a bright spot in the application. We have done on this test, the traditional 54M wireless router and 802.11N routing significantly compared to the gap from the test results, for home users of wireless devices support HD video playback is a trend. For enterprise users, office use wireless VOD service to make a video call, the hotel wireless network will allow users to truly experience the mobile office and mobile entertainment convenience. Three: mobile application portability Because 802.11N uses a unique antenna technology, the maximum extent to reduce th
