      How Does WiFi Work?

      Over the past decade, WiFi/wireless networking has become very popular. Low cost and simplicity are some of the reasons why WiFi is so popular. Today,  it is almost impossible to buy a laptop that doesn’t have a wireless card built into the screen, which is why WiFi’s popularity continues to grow. What Does WiFi Stand For?

    • WPA (Wi-Fi Protected Access)

      WPA (Wi-Fi Protected Access)

      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

    • WEP Key Passphrase

      WEP Key Passphrase

      A wireless network key is an encryption key for that prevents unauthorized users from accessing a specific wireless network. The user creates wireless network keys, which either a wireless router or a computer that is connected to that wireless router can manage. Wireless network keys can be any length greater than eight characters and can

      How to Access a Netgear Router

      You can manually connect to a Netgear router by plugging an Ethernet cable into both the router and computer. Once this connection is established, you can type 192.168.1.1  (the default IP address) in the browser in order to access the Netgear router interface. A dialog box should appear asking for the username and password, which

      802.11i

      The 802.11i wireless standard was released by the IEEE on June of 2004 and implements improved encryption for wireless networks than realized on past standards released. Commonly referred to as the WPA2 implementation, the 802.11i implementation requires newer encryption standards than seen with the WEP implementation by requiring TKIP (Temporal Key Integrity Protocol) and AES

    • W-CDMA (Wideband Code Division Multiple Access)

      W-CDMA (Wideband Code Division Multiple Access)

      WCDMA (Wideband Code Division Multiple Access) is the radio access scheme used for third generation cellular systems that are being rolled out in various parts of the globe. The 3G systems support wide band services like high speed Internet access and video and high quality image transmission with the same quality as the fixed networks.

    • What is Intersymbol Interference?

      What is Intersymbol Interference?

      Intersymbol interference is a signal distortion in telecommunication. One or more symbols can interfere with other symbols causing noise or a less reliable signal. The main causes of intersymbol interference are multipath propagation or non-linear frequency in channels. This has the effect of a blur or mixture of symbols, which can reduce signal clarity. If
