A WiFi antenna is a device that sends and or receives radio signals that computers and other electronic devices use to facilitate wireless communication with each other. While WiFi antennas have many uses, they are most commonly found in or on wireless routers. A wireless router is a device that creates a wireless computer network …
The Linksys network router is one of the most popular home and office networking pieces of equipment sold by Cisco. The company has produced Linksys routers supporting the latest version of the 802.11 standard for more than a decade with the most current models capability of supporting the 802.11N standard supporting extremely high throughput for …
CCMP (Counter Mode with Cipher Block Chaining Message Authentication Code Protocol) is the preferred encryption protocol in the 802.11i standard. CCMP Cryptography CCMP is based upon the CCM mode of the AES encryption algorithm. CCMP utilizes 128-bit keys, with a 48-bit initialization vector (IV) for replay detection. The Components of CCMP The Counter Mode (CM) …
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, …
In antenna engineering, a dipole is the most basic type of antenna and serves as basic framework for all other antennas. Dipoles consist of a metal rod that acts as a conductor with a radio feed line at its core. The conductor splits the signal and creates a positive electrical charge on one end of …
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 …
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 …
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 …
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 …
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 …
