widely used in the technology is 802.11 families, it is the first wireless LAN standard published by IEEE in 1997, and now the 802.11b, which is frequently mentioned in the media, is approved in September 1999, and it is also called Wi-Fi (sounds a bit like the music enthusiasts say Hi-Fi), Can support a shared access rate of 11Mbps , similar to the 802.11A technology, it uses the 5GHz frequency band, its speed is as high as 54Mbps, the frequency div

Today, MediaTek announced today the launch of the 802.11AC high-order wireless network single chip MT7615. This chip supports multi-user multiple input multiple output (Mu-mimo, multi-user multiple-input multiple-output) and transmission beam forming technology. MT7615 runs in the 2.4GHz and 5GHz dual band, regardless of long distance communication, at the same time is one or more users, users can enjoy the ultra-high data throughput of wireless netw

connections, but it is still difficult to carry more and more data, video, voice, and so on, and most people will choose free Wireless LAN. In households, such traffic is not popular with residential broadband access. In the work area, Gast recommends using an employee-specific channel to connect to the company's Wireless LAN network, or at least to the portion of this setup. Prepare for 802.11AC and 802.11AD standards Just as before 802.11n became a market leader, most companies are waiting

most known of the typical system. Many of these products, such as the Alcatel Company's A9800 system, NEC's Dmmass, Datang's PMP1560, and IRC's June, have been operating at a 15ghz,19ghz,24hgz and higher frequency. System coverage can be 5-60 km (without relay station), can also be 500--600 km (plus relay station). Rural areas, deserts, mountains and islands are useful for such products.3, the use of satellite communications technologyAs we all kn

Wireless network card definition of the so-called wireless networks, is the use of radio waves as a medium of information transmission of the wireless local area network (WLAN), and the use of wired network is very similar to the largest difference in the transmission medium, the use of radio technology to replace the network cable, and wired network for backup, but too slow Wireless network card is the equipment of the terminal wireless networks, wireless LAN wireless coverage under the wirele

, from a single antenna to a dual antenna to the three-day line, signal intensity is from weak to strong, of course, the price is from low to high, on average, single antenna without line from the starting price of dozens of yuan, dual antenna without line from the start hundred Yuan, Three antennas without a line from the starting price will be 200 yuan. In addition, the route also has a single frequency of the two-frequency division, frequency refers to a simple 2.4GHz frequencies, dual-freque

International standard update and improve, Further standardizing the development and application of products with different frequency points and higher network rate products, in addition to the content of original IEEE802.11, the Management Information Base (MIB) based on SNMP (Simple Network Management Protocol) protocol is added to replace the management information base of the original OSI protocol. In addition, high-speed network content has been added. IEEE802.11 points ieee802.11a and iee

gigabit interface, at the same time does not support the 802.11AC 5GHz dual-frequency wireless transmission, the interface has not joined the support of USB devices, it can be said that relatively current mainstream configuration somewhat behind. But this also with its concise and practical positioning as well as the price of 99 yuan, it is more in the wireless content to do the article, can be shared in the LAN music membership account. le-View rou

The British Computing.co.uk Web site reported that Intel will "in a few weeks" launch the first 4GHz processor. This means that Intel and AMD will restart the war on CPU frequencies. The new core i7-4790k "Devil ' Canyon" processor will be the first of the Intel 3 LGA1150 interface Haswell processor. The specific parameters of this processor include: 4 CPU core, support Hyper-threading, 4.4GHz Core frequency acceleration, 8MB cache, thermal design power 88 watts. This processor integrates the H

If the user knows the caller's iphone 4 phone number, it can also be directly in the contact interface to enter the other number to achieve FaceTime call. However, the user must obtain a Wi-Fi connection. 10. What else does the new ipod touch have to share with the iphone 4? As already mentioned, the ipod touch uses the same Retina display

Recently, with Nvidia Tegra 4 game Equipment shield again ushered in OTA update, despite only 20 trillion of update package, but the home page you think this is only 20 trillion update files, has opened the mobile game and even the entire gaming industry a new era. The biggest change of OTA update is to join the grid cloud game function, is still in beta testing phase. Press the Nvidia button in the middle of the shield to find the grid icon in Tegra Zone There will be a few seconds of loading

From the application requirements, the wireless network is very suitable for schools of some sites that are not easy to network wiring applications. Now most of the campus has wired LAN, how to further expand the original network, so that every corner of the campus in the network, the formation of a true sense of the campus network? This article is to introduce how to use Wireless LAN technology to form a campus network. Wireless network Infrastructure Wireless LAN (Wireless local area network

network card, which is used by both the Centrino model and the non-Centrino wireless network card standard models. The advantage is that it eliminates the need for a PC card or USB slot and eliminates the hassle of carrying a PC Card or USB card at any time. At present, these kinds of wireless card in the price gap is not small, in performance/function is also similar, on demand and choose. Interface type 1.

fold. Receive Combining cannot be confused with antenna diversity (antenna diversity). The antenna diversity does not select signal elements based on the intensity of different signals in different frequencies or from the intensity of the signal enhanced by using two antennas. A receiver with an antenna diversity chooses only the antenna that provides the best performance, while the second antenna is not. Although this technique does have its advantages over the absence of any antenna diversit

The gradual entry of the IEEE 802.11-based WLAN into the mainstream network makes fault diagnosis and security for wireless networks as important as wired networks. An analyzer that supports multiple modes can scan all 802.11 bands, including all channels in the 2.4GHz and 5GHz bands, and graphically display them to see if the configuration is reasonable, what the SNR is, how much bandwidth is available, and other related issues. If an AP has a promi
