Abramson‚ a professor at the University of Hawaii‚ developed the world’s first wireless computer communication network‚ ALOHAnet (operational in 1971)‚ using low-cost ham-like radios. The system included seven computers deployed over four islands to communicate with the central computer on the Oahu Island without using phone lines. Definition A wireless local area network (WLAN) links two or more devices using some wireless distribution method (typically spread-spectrum or OFDM radio)‚ and usually

INTRODUCTION Communication is always necessary in building relations to mankind‚ when two persons meet they need some medium to interchange their views but due to distance barriers some tools are required to communicate each other. At the end of 19th century‚ reckoned \scientist Graham Bell laid the first stone in the field of communication using different tools regardless of distance. He invented first wired base telephony equipment. It was the solution for the voice communication for the people

Abstract: Wireless technologies have experienced an enormous growth in the last decades. The wireless personal area networks (WPANs) and wireless local area networks (WPANs) are heterogeneous networks which are used in different applications. Two networks‚ called Wifi (IEEE 802.11 WLAN) and ZigBee (IEEE 802.15.4 WPAN)‚ which operates in 2.4 GHz frequency. Spectrum sharing is an effective technique which is used to enhance spectrum utilization. However the coexistence and Interoperability is a critical

WIRELESS VIBRATION MEASUREMENT SYSTEM Vibrations are caused due to mechanical oscillation of a structure about an equilibrium point. There will be vibrations involved everywhere where there is any rotating system‚ mechanical system is involved. The vibrations involved at in these places will of high frequency. There will some places where the vibrations of lo0w frequency will be present which will also disturb the normal operation of the system or faultiness in the values measured by the system
