can not meet the growing business needs, so IEEE in 1999 has launched a 802.11b, 802.11a two standards. And at the end of 2001 through the 802.11G Trial hybrid scheme, which can achieve 54Mbps data rates in the 2.4GHz band, and compatible with the 802.11B standard. 802.11b work in 2.4GHz ISM (industrial, technical, medical) band, using direct series spread spectrum and complement keying, can support 5.5Mbps and 11Mbps two kinds of speed, can with the rate of 1Mbps and 2Mbps 802.11 DSSS (direct

Denial of interference to solve the biggest problem with Wi-Fi802.11 technology has grown dramatically over the last 10 years – faster, more powerful, and more scalable. But one problem still haunts Wi-Fi;There is nothing more than users complaining about Wi-Fi performance is not stable, coverage is not good, often drop the network manager to crash. Addressing Wi-Fi, an invisible and changing environment, is really a problem. and radio frequency interference is also a culprit.RF interference com

it works in both 2.4Ghz and 5Ghz unlicensed bands.When a 802.11 client device hears other signals, whether or not the signal is a WiFi signal, the device will suspend the transfer of data until the signal disappears. Interference in data transmission can result in packet loss, forcing WiFi to retransmit data. Retransmission results in decreased data throughput and a pervasive impact on users sharing the same AP.While the spectrum analysis tools are n

Over the past decade, 802.11 technology has made great strides----faster, stronger and more scalable. But there is a problem in the troubled Wi-Fi: reliability. for network administrators, the most frustrating for them is that users complain about the poor Wi-Fi performance, the coverage is not stable, often drop the line. Dealing with a Wi-Fi environment that you can't see and change frequently is a tricky problem. The culprit of this problem is radio frequency interference. almost any device

6GHz, for short-range wireless communication, Officially designated as the successor of 802.11N, the other is 802.11AD, working in 60GHz, market positioning and UWB similar, mainly for home entertainment equipment. At that time, however, the 802.11AC standard had not even entered the draft stage. The new draft standard was expected to be available by the end of 2011 and will eventually be completed by November 2012. The difference between 802.11AC and 802.11n From the core technol

of high speed can only be achieved under the 5Ghz band)Another: Some people may say, my home bandwidth is limited, 54M is enough to use, high bandwidth is useless, in fact, I said, those are only negotiated rate, the actual use of the entire wireless system throughput, delay or even signal, may be due to different negotiation speed, even if your home only 6 m broadband, It's likely that after you switch to a high-end wireless card and a relatively go

WLAN.8.1.1 Frequency and Channel1, the general Wireless frequency band can be divided into: industrial, scientific and pharmaceutical ism Wireless band.2, 802.11 can work in the ISM band at 2.4GHz or 5GHz, and a 802.11n device can define the bands it can run.3, in the 5GHz band, all channels are non-overlapping.Establishment of 8.1.2 sessionTwo main types of wireless networks: Infrastructure netwo

interfere with the normal use of wireless routers. In particular, part of the digital cordless phone use of 2.4GHz band, so that when the network is unstable through the wireless router to replace a signal transmission band is a good way. Set the method as shown in the following illustration: ▲ Frequency Bands Division As can be seen from the above figure, this router can simultaneously provide 2.4ghz/5ghz dual-band wireless signal!

2.4GHz ISM band, and the total data transmission rate is designed as 2mbit/s. Communication between the two devices can be done in a device to device (ad hoc) manner, or in coordination with the base station (base station, BS) or access point (Access Point,ap). In order to obtain good communication quality in different communication environment, the hardware communication mode of CSMA/CA (Carrier Sense Multi access/collision) is adopted. In 1999, two additional versions were added: 802.11A def
