Zig Bee Standard For Personal Area Networks

1397 words - 6 pages

1. An introduction

ZigBee is the new standard which is developed by ZigBee Alliance for personal area network (Pans). Consisting of over 270 companies (including Freescale, Ember, Mitsubishi, Philips, Honeywell, and Texas Instruments), ZigBee Alliance is a consortium that promotes the ZigBee standard for wireless sensor and control network low-rate/low-power. ZigBee protocol stack designed for IEEE 802.15.4, which defines the Media Access Control (MAC) and physical layer for low rate wireless personal area networks (LR-WPAN). ZigBee standard offers a profile that defines the network layer stack, security, and applications. Developers must be responsible for their own created application profile or integrate with public a profile which is developed by the ZigBee Alliance. ZigBee specification is an open standard which allows manufacturers to develop their own specialized applications requiring low cost and lower energy.

The manual was prepared an introduction to the various components of the ZigBee network. After a quick overview of ZigBee, we begin with a description of high level concepts which are used in wireless communications and move to specific protocols required to perform communication standards. This is followed by a description using the Rabbit-based boards and Dynamic C library to create a ZigBee network.

2. The technology’s application: where, how it works and who is using it.

Where it works?
Freescale has wide portfolio of ZigBee-enabled ICs and low-power microcontroller (MCU) which forms an ideal platform for ZigBee-enabled network. MC13224V Freescale ZigBee ™ Platform package (PIP) is the newest low-power our platform for ZigBee devices. The highly integrated pip MC13224V simplify RF design, allowing many clients that does not have wide experience in RF still create ZigBee-enabled design firm. Freescale also has several reference designs, including details of the design for the hardware in the development kit. You can pick up bill of materials, Gerber files and schema and either copy our design or integrate into your. Complete platform approach helps reduce development time and speed time to market.

How it works?
ZigBee networking works as a peer-to-peer. For this you can communicate through the radio frequency reliably as long as there are other devices in the area. For the Zigbee alliance it is a group of companies that produce wireless communication device that is reliable, affordable, and have low power requirements. ZigBee standard was created in the late 1990s, when it becomes clear that Bluetooth will not be a suitable for certain applications. It is designed as a lower-cost, lower power version of a personal wireless network. Currently, ZigBee devices meet the very different requirements of Bluetooth devices, and thus do not interfere with the Bluetooth market. These devices have very low power usage, which extends battery life significantly.

Who is using it?
Actually zigbee is also like the other internet Unifi,...
