Mesh technology is not new. It is a technique that has been tried with varying success by a number of vendors of proprietary broadband wireless technology for some time. Some firms have met with great success in developing mesh technology for military applications for example. It is basically a physical ...

The term "base station" was first used to refer to the towers you see on the side of the road that relay cell phone calls. These stations handle all cellular calls made within their area, receiving information from one end of the call and transmitting it to the other. In the ...

The current implementations of code signalling, message delivery, and code protocol fall short of providing adequate call party authentication, end-to-end integrity, and confidentiality of messages with VoIP. VoIP converts voice signals from the telephone into digital signals ...

With respect to the International Standards Organization’s (ISO) seven layer Open Systems Interconnection (OSI) model, the 802.11 standard directs only layer one (Physical) and layer two (Data Link or Medium Access Control (MAC)) specifications. The encapsulation of data within each successive layer enables all lower layers to function without regard for their higher layer payloads. This chapter ...

The 802.11 standard describes the communication that occurs in wireless local area networks (LANs). The Wired Equivalent Privacy (WEP) algorithm is used to protect wireless communication from eavesdropping. A secondary function of WEP is to prevent unauthorized access to a wireless network; this function is not an explicit ...

 A passive eavesdropper can intercept all wireless traffic, until an IV collision occurs. By XORing two packets that use the same IV, the attacker obtains the XOR of the two plaintext messages. The resulting XOR can be used to infer data about the contents of the two messages. IP traffic ...

When setting up a system which strictly demands the usage of WEP encryption for all data transmissions, all the WavePOINTs in the system must be configured to have the parameter “Deny non-encrypted Data” set to ON (checked in the tickbox). This will assure that only stations with WEP encryption enabled can connect to the ...

The 802.11b standard includes a provision for encryption called WEP (Wired Equivalent Privacy). Depending on the manufacturer and the model of the NIC card and access point, there are two levels of WEP commonly available - one based on a 40-bit encryption key and 24-bit Initialization Vector (also called 64-bit ...

SAN DIEGO — July 02, 2007 — QUALCOMM Incorporated (Nasdaq: QCOM), a leading developer and innovator of advanced wireless technologies and mobile data solutions, and NTELOS, (Nasdaq: NTLS), a leading provider of wireless communications services in Virginia and West Virginia, today announced plans to launch the first BREW® ...

Interference can severely degrade the performance of wireless LANs, finds a new technical note from Farpoint Group. Just how bad is it? Consider the throughput reductions caused by these common devices: Microwave oven - 62%; another wireless LAN - 89%; Bluetooth headset - 20%; cordless ...

WEP is now severely broken. For those not familiar with the subject: WEP is a mechanism that protects sensitive data transmitted over a wireless network (conforming to IEEE 802.11 x standards) from being revealed to an attacker. It uses an algorithm called RC4 (designed by Ron Rivest). The following is ...

There are many reasons why a wireless signal strength is low or experiencing interruption, including: Range of the wireless modem/router - for the average home, the range of the wireless signal should not be a problem. Range is limited by the number of walls, ceilings, or other objects that the ...
