By Reading this Paper you are able to Understand the Meaning of Technology and Zigbee Technology and Comparison between them in Technical term . 2. INTRODUCTION In the Past, Information is Transferred from one device to the another device with the help of the Cable. This Process is Expensive and not suitable for the faithful Communication due to its Hardware Complexity. technology first developed by Ericsson in 1994. Main aim of this Technology was to Remove the need of the Cable Connection between Devices such as PDA and PCs. Although the Infrared Communication Existed at time. It required Line of Sight Contact. Due to Unlimited Potential of BWT the special group was formed in 1998 to develop the Specification IEEE 802.15. ZigBee-style networks began to be conceived around 1998, when many installers realized that both WiFi and were going to be unsuitable for many applications. ZigBee is a specification for a suite of high level communication protocols using small, low-power digital radios based on an IEEE 802 standard for personal area networks. ZigBee has a defined rate of 250 kbit/s, best suited for periodic or intermittent data or a single signal transmission from a sensor or input device. 3. BLUETOOTH The SIG adopted the code name as a tribute to the tenth-century Viking king Harald Blatand who peacefully united Denmark and Norway. Harald liked to eat blueberries, which gave his teeth the coloration that lead to the nickname Bluetooth. technology was invented in 1994 by engineers at Ericsson, a Swedish company. In 1998, a group of companies agreed to work together using technology as a way to connect their products. These companies formed the Special Interest Group (SIG), an organization devoted to maintaining the technology. This means that no single company owns technology, but that many members of the SIG work together to develop technology. technology was originally intended to be a wireless replacement for cables and wires between things like phones and headsets or computers, keyboards and mice. technology has continued to mature and now you can create new connections that weren't possible using wires, like connecting your mobile phone to your car stereo, or printing a picture directly from your camera phone. 3.1 BASIC OF BLUETOOTH The key features of technology are robustness, low power, and low cost. The Specification defines a uniform structure for a wide range of devices to connect and communicate with each other. When two enabled devices connect to each other, this is called pairing. The structure and the global acceptance of technology means any enabled device, almost everywhere in the world, can connect to other enabled devices located in proximity to one another. IJSER International Journal of Scientific & Engineering Research, Volume 4, Issue 6, June-2013 227 ISSN 2229-5518 IJSER © 2013 http://www.ijser.org Connections between enabled electronic devices allow these devices to communicate wirelessly through shortrange, ad hoc networks known as piconets. Piconets are established dynamically & automatically as enabled devices enter and leave radio proximity meaning that you can easily connect whenever and wherever it's convenient for you. Each device in a piconet can also simultaneously communicate with up to seven other devices within that single piconet and each device can also belong to several piconets simultaneously. This means the ways in which you can connect your devices is almost limitless. The range of technology is application specific. The Core Specification mandates a minimum range of 10 meters or 30 feet, but there is no set limit and manufacturers can tune their implementations to provide the range needed to support the use cases for their solutions. It separates the frequency band into hops. This spread spectrum is used to hop from one channel to another, which adds a strong layer of security. Signals can be transmitted through walls and briefcases, thus eliminating the need for line-of-sight. Devices do not need to be pointed at each other, as signals are omni-directional. Both synchronous and asynchronous applications are supported, making it easy to implement on a variety of devices and for a variety of services, such as voice and Internet The Aim of Bluetooth has been set quite high. It is to arrive at a specification for a technology that optimizes the usage model of all mobile computing and communications devices, and providing Global usage ,Voice and data handling. The ability to establish ad-hoc connections.
