...ZIGBEE TECHNOLOGY Raghda Al-dwaimeh . University of Jordan. Abstract—this document describes the concept of ZigBee. It is wireless network standard. Possible network topologies and device types are shown. Finally, the application of ZigBee devices in everyday life was proposed. 802.15.4 standard for wireless networks and full mesh networking support, 128bit AES security. III. HISTORY ZigBee-style networks began to be vision around 1999, when many installers recognized that both Wi-Fi and Bluetooth were going to be unsuitable for many applications. ZigBee 2004: The IEEE 802.15.4-2003 standard was completed in May 2003. ZigBee 2006: In September 2006, the ZigBee 2006 specification was announced. The 2004 stack is now, more or less ignored ZigBee PRO: In 2007, ZigBee PRO, the enhanced ZigBee Pro Specification, was posted on 30 October 2007, and was finalized that same year. I. INTRODUCTION ZigBee is a low-cost, low-power, wireless mesh networking standard. The low cost allows the technology to be widely deployed in wireless control and monitoring applications, the low power-usage allows longer life with smaller batteries, ZigBee devices can transmit data over long distances by passing data through intermediate devices to reach more distant ones, and the mesh networking provides high reliability and larger range. The ZigBee Alliance, the standards body which defines ZigBee, also publishes application profiles that allow multiple OEM vendors to create interoperable...

...a whole new network structure for the purpose of being more optimal and maintaining standards that keep up with advances in new technology. In most cases, a hospital’s network can transition over time with new technology and evolve into meeting the demands it requires to perform effectively. However, upgrading a hospital’s entire network can often be very expensive to implement and sustain. There may be a case where components or parts are no longer being produced to meet current and future demands. In the last several years, changes in healthcare put a demand on hospitals to maintain their networks with new, more efficient solutions that can enhance performance, keep cost low, but most one that is reliable . The Network architecture at Patton-Fuller hospital was designed for each department to rely on information flow between each department. In other words, if the accounting department needed information from the pharmacy or admissions in order to create invoices or insurance billing, it would be rely on those departments to share real time information through the network. It is important for a facility as large as a hospital to have a Networking system that information management (IM) can efficiently support the information flow. The Network architecture must have a design that is capable of supporting large amounts of data being transmitted through the Network server because it is the largest consumer of an information system (IS). By having a Network that is “efficient”...

...[pic] ZigBee Wireless Mesh Networking for Monitoring & Control What is ZigBee? ZigBee is a consortium of software, hardware and services companies that have developed a common standard for wireless networking of sensors and controllers. While other wireless standards are concerned with exchanging large amounts of data, ZigBee is for devices that have smaller throughput needs. The other driving factors are low cost, high reliability, high security, low battery usage, simplicity and interoperability with other ZigBee devices. ZigBee can be used in commercial applications such as building maintenance for monitoring and controlling lights, Heating, Ventilation and Air Conditioning (HVAC), smoke alarms, fire alarms, burglar alarms, landscaping sprinklers and lights and many other uses. In health care, ZigBee can be used for patient monitoring equipment, fitness monitoring and other uses. Industrial environments can use ZigBee for asset monitoring, process control, assuring compliance with environmental standards and energy management. Used correctly, ZigBee enabled devices can give a warning before a breakdown occurs so that repairs can be made in the most cost effective manner. They can also be used to maintain quality and reduce waste. Soon, ZigBee enabled devices will show up in our homes. They will be used for controlling our home entertainment systems, lights, garage door openers, alarms, panic buttons, and many other uses. Imagine your...

...Introduction (100-User Wireless LAN-Design & Implementation Analysis) In this document, I will endeavor to provide a written analysis concerning the design and implementation of a wireless LAN (WLAN) for a firm comprised of one hundred employees. In illustration of the WLAN design, I will make reference to several sources regarding any related content that I’ve found to be pertinent and of practical benefit to this document’s purposes, not least of which is “ Top-Down Network Design ”, by Priscilla Oppenheimer, an instructional text detailing a method of network design that’s based upon what can be readily found evident throughout the overall networking community to be the most logical and efficient sequence of steps necessary in the creation of a network. Having stated this, it is of value for the reader to know that the aforementioned sequence of steps, as examined in Oppenheimer’s work, will correspond closely to the order of WLAN design and management issues that are addressed in this document, and can be followed up by way of documentation found under the same title and author at the end of this article. The major design and management issues found unique to a WLAN involve those pertaining specifically to the transmission and reception of radio frequency (RF) waves. For example, there is the strategic placement of access points (AP), which are devices designed to send and receive radio signals between nodes. This, in turn leads to a consideration of any possibility...

...up a Home Network Srikanth Gunda Wilmington University 1. Overview of wireless networking technology There are various types of wireless network which are wireless Local Area Network (WLAN), Wireless personal Area Network (WPAN), Wireless mesh Network. Wireless networks are convenient in home network, small schools and offices. Wireless network are basically suitable to interconnect cell phones and computers, printers, TVs which helps in easy communication. Wireless network uses radio frequency rather than wire to communicate. Clients unite their gadgets which helps to communicate Wireless access points. The speed is relative to distance between the transmitter and receiver due to the utilization of radio frequency; consequently, the closer the client is to the transmitter the more the speed is. 2. Advantages of wireless networking technology Wireless networking technology gives various benefits to the household and office use, some of these benefits are below:- I. Most of the working class families have few computers which are arranged in various rooms. It is expensive, and time-consuming to introduce cables to a network that are situated in rooms which helps them to impart the broadband communication hence a wireless router resolves the issue. II. As the clients stay in the coverage of the signal, he/she can move their gadgets easily around the house. This protects hours of cable reconnection as the gadgets can get web by long wireless facility. ...
