Wireless networks are those computer networks that use electromagnetic waves instead of wires in order to carry signals over the various parts of the network. Wireless networks which run over other wireless networks often utilize the lower layer networks to provide security and encryption. Stand-alone wireless networks either provide their own security and encryption features …
The SSID (Service Set IDentifier) is a name that identifies a specific 802.11 wireless network. The name is set by the network administrator who configures the router. Some vendors refer to the SSID simply as the “network name.” The SSID is the name of the wireless network and should not be confused with the host …
A wireless router is a computer networking device that routes data packets across another computer or across a wireless IP network. The wireless router comes with an 802.11 interface card and antenna. The wireless router antenna is generally what determines the signal strength of the wireless router. If your signal strength is weak, then you …
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 …
CDMA-2000 1xRTT is a 3G wireless technology based on the CDMA platform. The 1x in 1xRTT refers to 1x the number of 1.25MHz channels. The RTT in 1xRTT stands for Radio Transmission Technology. The CDMA-2000 1xRTT protocol was developed by Qualcomm. CDMA-2000 1xRTT is a CDMA version of the IMT-2000 standard which was developed by …
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 …
Windows and other operating systems have a WiFi signal strength meter, but this is usually basic software and does not really tell the user much about the wireless signal. Fortunately, there are many other programs that do the same thing, but show the user more details about the wireless connection. We will describe some of …
The first thing you can try to increase a WiFi signal is to move the laptop computer or mobile device closer to the source of the network that is being accessed. If you have control over the router of the network, you can increase the wireless signal by placing the router on a high area …

Westell is a provider of DSL routers and other DSL-based devices that telephone companies and DSL subscribers use for wireless Internet in homes or offices, instead of using cable or satellite Internet. Westell products generally have the same features as other routers, such as dual antennas, four Ethernet ports, and WPA encryption, but connect to …
