Wireless Internet has numerous advantages, but there are also certain limitations. For example, your computer has to be within the range of wireless broadcasters like routers and WiFi hotspots. Sometimes your computer may be in the range of one of these broadcasters, known as “wireless access points”, but it may not be getting much of …
802.11b is the standard that is popularly used for high speed wireless networks. The standard is set by IEEE (Institute of Electrical and Electronics Engineers) and uses a 2.4 gigahertz radio frequency. There are several standards that are in use today for wireless communication from one computer device to another; however 802.11b is cost effective, …
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 …
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 …
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 …

A message integrity check (MIC), is a security improvement for WEP encryption found on wireless networks. The check helps network administrators avoid attacks that focus on using the bit-flip technique on encrypted network data packets. Unlike the older ICV (Integrity Check Value) method, MIC is able to protect both the data payload and header of …
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 …
