Wireless Connectivity

ISM, WLAN, WMAN,Bluetooth et al.

Wireless data communication is the latest rage. From wireless mice to Formula-1 telemetry systems, digital radio systems are used in many applications, and they are penetrating intomany new areas. In this article, we examine the current state of affairs in the ‘airwave jungle’.
The enormous popularity of wireless communication is a direct consequence of international agreements to designate certain regions of the radio spectrum as ‘ISM bands’, since widespread use of wireless connectivity would otherwise never have been possible. The demand for unrestricted mobile communication is the driving force behind the rapid development of technologies such as Bluetooth, WLAN, HomreRF, and other new technologies with resplendent names.
