advantages and disadvantages, and analysis of its application in the power system prospects. second, wireless technology introduction (i) The concept of wireless communication technology at present, wireless communication and its application has become one of the most active research fields of information science and technology nowadays. It is generally co

With the development of the routing industry, wireless technology has become its development direction. Here we mainly explain the differences and connections between wireless routers, wireless APs and wireless bridges, I hope to have a deeper understanding of wireless devic

the same network. Like 802.11b, IEEE802.11g also works in the 802.11 GHz band, which is 5 times faster than the current general 802.11b and fully compatible, when purchasing a device, we recommend that you check whether the protocol standard is supported. Select the one that suits you. The 802.11g standard is now available. 4. What are wireless networks? Wireless Personal Network (WPAN):

with certain mobile features. Users are primarily laptop terminals and 802.16e terminal holders. 802.16e can access the IP core network and provide VoIP services. 3G was initially designed for both voice and data services. For voice services, core networks still adopt circuit switching to ensure high QoS. 802.16e sacrifices mobility in exchange for improved data transmission capabilities. Its data bandwidth is superior to that of 3G systems. However, the 3G data capability is constantly improvi

　　Wireless AP: AP for access point abbreviation, generally translated as "Wireless Access Node", which is mainly to provide wireless workstations to the wired LAN and wireless workstations from the wired LAN access to the wireless workstation in the access points covered by

Whenever we walk in and out of the elevator corridor or underground tunnel, we will inadvertently pull out their own mobile phone, to test the position of the communication signal strength at this moment. In fact, wireless internet also has the problem of signal strength, when wireless internet nodes or wireless router devices placed in different locations in the

criteria To reduce costs, ensure synergy and improve the wider use of wireless technology, many organizations (e.g. the Institute of Electrical and Electronic Engineers (IEEE), Internet Engineering Task Force (IETF), Wireless Ethernet Compatibility Alliance (WECA) and the International Telecommunication Union (ITU) ) have been involved in several major standardization efforts. For example, the IEEE workgr

Wireless network card is the equipment of the terminal wireless networks, wireless LAN wireless coverage under the wireless network for Internet access to the use of radio terminals. Specifically, the wireless card is a device tha

high-speed Downlink packet Access (HSDPA) (known as 3.5G), the rate can reach 10mbit/s above, and then further in the R6 to increase the high-speed uplink packet Access (HSUPA), the core network is also evolving to the full IP network. To compete with WiMAX, 3GPP developed a long-term evolution (LTE) program (known as 3.9G) at the end of 2004. 3.2 Wireless Broadband access Technology Broadband Wireless a

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,

Use of ruijie in Wireless AP (Wireless Router ruijie wireless Internet access cannot authenticate AP) [tested: win7, xp, ubuntu 12.04 LTS are OK]Many campus networks or enterprise networks require ruijie verification. Although ruijie tries to control the use of wireless routers to prevent a single account from being sh

WDS (Wireless distribution system), wireless distributed systems: is constructs under HFSS or DSSS, may allow the base station and the base station to be able to communicate, compared is has the WDS function is may when the wireless network repeater, and may many Taiwan base station to one station, There are currently many wi
