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 …
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 …
Wireless networking has grown from only being a tool employed by academia and Fortune 500 companies to being deployed in locations such as McDonald’s, Starbucks, and gas stations for free consumer use over the past decade. Consumers can install a wireless network in the home for minimal cost today, and many home theater set-top boxes …
Bluetooth dial-up networking (DUN) is a wireless Internet technology that refers to connecting to the Internet with a Bluetooth enabled cell phone as a modem. Bluetooth DUN offers a low band alternative where there are no local hotspots to provide high speed wireless Internet access. Bluetooth is a wireless protocol that allows wireless communication to …
What is a Wireless Router? A wireless router is a device that wirelessly connects multiple computers and devices to the Internet. Wireless routers’ design and capabilities vary and they drastically range in price, but are used for the same function. Wireless routers are usually very easy to setup and many provide the user with built-in …
SMS (Short Message Service) is a protocol for sending and receiving brief text messaging over digital cellular networks. Most people send SMS messages from the very small keypads on their mobile phones, and most people who receive SMS messages read them on the tiny screens of their mobile phones. Because of those considerations, and because …
802.1x is an IEEE standard that provides the definition for the encapsulation of EAP (Extensible Authentication Protocol) and is also known as EAPOL (EAP over LAN). The standard was first defined in 2001 and later clarified in 2004 to be used with other IEEE 802 working group defined technologies such as the 802.11 wireless standard. …
An ad hoc network is a type of peer to peer wireless network mode where wireless devices communicate with each other directly, without the aid of a Wireless Access Point (WAP) device. Wireless networks typically depend on a base station or WAP device to manage and direct the stream of data between wireless devices. In …
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 …
Multicast is the transfer of messages to multiple destinations simultaneously, using fewer networks. The information is delivered to each of the links only once, and copies are created when the links to the destinations split, thus creating an optimal distribution path. Multicasting reduces unnecessary packet duplication. A wireless network utilizes radio communication, unlike wired networks, …
