Wireless

Navigation: Main page

Wireless is a method of communication that uses low-powered radio waves to transmit data between devices. The term refers to communication without cables or cords, chiefly using radio frequency and infrared waves. Common uses include the various communications defined by the IrDA and the wireless networking of computers. Low-powered radio waves, such as those used in networking to transmit data between devices, are often unregulated. High powered transmission sources usually require government licenses to broadcast on a specific wavelength. This platform has historically carried voice and has grown into a large industry, carrying many thousands of broadcasts around the world. Radio waves are now increasingly being used by unregulated computer users. Optimal bandwidth routes within wireless networks requires the calculation in real-time of the best way to direct traffic. Software and hardware developers are creating smaller computer networks which form ad-hoc wireless network, with protocols such as WiFi and ZigBee. The IEEE 802.11 standard is for wireless, Ethernet-like LANs. The insecurities in this protocol have popularized the concept of war driving.
