Nowadays nearly all new notebook computers have built-in 802.11a/b/g/n/ac wireless adapters. However, the built-in wireless adapters on some old notebooks may support 802.11b only. Besides, some older notebooks have no built-in wireless adapters at... Read More

IEEE 802.11 is the wireless local area network (WLAN) standard developed by the Institute of Electrical and Electronics Engineers (IEEE). 802.11a, 802.11b and 802.11g are 3 most well-known 802.11 specifications. 802.11b and 802.11g standards use... Read More

On some occasions, you need to remove the eduroam setting on your device.  For example, when you change your ITSC account password, you need to remove the eduroam setting and re-create it. Please visit the corresponding sections to follow the... Read More

Temporal Key Integrity Protocol (TKIP) is a security protocol used in Wi-Fi Protected Access (WPA). TKIP provides per-packet key mixing, a message integrity check and a rekeying mechanism. Advanced Encryption Standard (AES) is a block cipher... Read More

Wi-Fi Protected Access (WPA and WPA2) is a class of systems to secure Wi-Fi networks. They are designed to replace the deficient older Wired Equivalent Privacy (WEP) standard. WPA implements the majority of the IEEE 802.11i standard, and was... Read More

A service set identifier (SSID) is a unique code attached to all packets on a wireless network to identify each packet as part of that network. This code is a case sensitive text string that consists of a maximum of 32 alphanumeric characters.... Read More

The actual data throughput of a 802.11b connection can be up to 5-6 Mbit/s while actual data throughput of a 802.11g connection can be up to 20-22 Mbit/s. The actual bandwidth will be inversely proportional to the number of simultaneous ... Read More

802.11n builds upon previous 802.11 standards. The expected data throughput of a 802.11n connection is up to 300-600 Mbit/s, which is similar to the rate of a typical wired connection. 802.11n tries to increase the data rate by using MIMO ... Read More

Many people are concerned about the radio power of wireless devices and worry that they may be harmful to the bodies and may lead to health problems. In May 2007, ITSC and SEPO has worked together to conduct a measurement on the Wi-Fi radio power... Read More
