The wireless throughput in Bytes per second averaged over two seconds.
Wi-Fi Alliance
The Wi-Fi Alliance is a nonprofit international association formed in 1999 to
certify interoperability of wireless Local Area Network products based on
IEEE 802.11 specification. The goal of the Wi-Fi Alliance’s members is to
enhance the user experience through product interoperability. The
organization is formerly known as WECA.
Wi-Fi Protected Access (WPA)
The Wi-Fi Alliance put together WPA as a data encryption method for 802.11
wireless LANs. WPA is an industry-supported, pre-standard version of
802.11i utilizing the Temporal Key Integrity Protocol (TKIP), which fixes the
problems of WEP, including using dynamic keys.
Wide Area Network (WAN)
A WAN consists of multiple LANs that are tied together via telephone
services and / or fiber optic cabling. WANs may span a city, a state, a
country, or even the world.
Wired Equivalent Privacy (WEP)
Now widely recognized as flawed, WEP was a data encryption method used
to protect the transmission between 802.11 wireless clients and APs.
However, it used the same key among all communicating devices. WEP’s
problems are well-known, including an insufficient key length and no
automated method for distributing the keys. WEP can be easily cracked in a
couple of hours with off-the-shelf tools.
Wireless LAN (WLAN)
A wireless LAN does not use cable to transmit signals, but rather uses radio
or infrared to transmit packets through the air. Radio Frequency (RF) and
infrared are the commonly used types of wireless transmission. Most
wireless LANs use spread spectrum technology. It offers limited bandwidth,
usually under 11Mbps, and users share the bandwidth with other devices in
the spectrum; however, users can operate a spread spectrum device without
licensing from the Federal Communications Commission (FCC).
