Information technology group Wi-Fi Alliance or WFA has been testing a next generation, yet still pre-standard wireless networking program that would define wireless Internet of the future. Much ado has been tackled about the technology called 802.11n. For the average Internet user, who knows not too much about the standards and technicalities of the information …
WPA (Wi-Fi Protected Access) is an interim standard by the WiFi Alliance to comply with the security protocol designed for wireless security. WPA will most likely be rolled into an eventual IEEE 802.11i standard. This protocol was an outcome of numerous severe flaws researchers had discovered in the preceding wireless security system called Wired Equivalent …
A wireless router is a wireless device that connects one computer or a whole network to another computer or network. It is possible to have a wireless network in a home or office. Travelers definitely come across wireless networks at most international airports. A wireless router, which is responsible for sending information from one computer …
WiMAX stands for Worldwide Interoperability for Microwave Access. WiMAX is a broadband wireless point-to-multipoint specification from the IEEE 802.16 working group. Unlike wireless LAN technologies such as Wi-Fi (802.11), WiMAX is designed to operate as a wireless MAN (Metropolitan Area Network). This places WiMAX in the same class as the earlier 802.16 standards, MMDS and …
Wireless routers are network devices that combine the functionalities of a router and a wireless access point. Wireless routers can be connected to broadband modems to provide wireless access to the Internet to two or more computers or laptops within a home environment. They enable greater mobility for laptops and other portable computers. They can …

Westell products generally have the same features as other routers, such as dual antennas, four Ethernet ports, and WPA encryption, but connect to …
A smart antenna is one that transmits or receives multiple radio frequencies at once. Smart antennas increase data transfer rates and reduce errors by handling several copies of the same information. Conventional antenna systems consist of one antenna that serves as a transmitter and one that serves as a receiver. This is starting to change, …
South Korea developed the WiBro (Wireless Broadband) technology in order to provide a high speed Internet solution for local consumers. The technology is based on the 802.16e standard which is more commonly known as the WiMAX standard in other countries. At the time of this writing, the capacity of the WiBro connections available in South …
TKIP (Temporal Key Integrity Protocol) is part of a draft standard from the IEEE 802.11i working group. TKIP utilizes the RC4 stream cipher with 128-bit keys for encryption and 64-bit keys for authentication. TKIP is an enhancement to WEP (Wired Equivalent Privacy) security. TKIP enhances WEP by adding a per-packet key mixing function to de-correlate …
