Introduction
There has been a rapid growth and development in the wireless network filed from the past several years. Till now the main focus of wireless networking is to provide high-speed and long range applications. There are many applications which requires low data rates, long battery life, and in expensive solution. What the market need is a standard which meets all the requirements such as secure data communication, low data rates, long battery life and inexpensive. Many solutions have been proposed to satisfy these needs but they are very expensive. A new standard called ZigBee has developed by the ZigBee Alliance which is based on the IEEE 802.15.4 standard for all wireless applications which satisfies all the needs in less cost. The expected applications where zigbee can be widely used are home/office automation, environmental monitoring, distributed sensor networks. The zigbee networking standard is emerging slowly and has taken an important share in wireless market. More and more types of zigbee are coming out and vendors of this product are increasing day by day.
History
Professor Shaofang Gong was very much interested in new wireless standards and applications. The Communication Electronics research group was leaded by Professor Shaofang Gong started working on the project in 1998. The entire project was carried out at ITN, Campus Norrkoping. As there is no particular standard which is covering the wireless sensor networking, professor Shaofang Gong, and the research group started investigate and working on how to manage large number of wireless networks and how to optimize the life time of the battery of a wireless sensor networks. The main aim of this project was to develop a fully functional wireless ZigBee .

Stephen Kern, a professor of history at The Ohio State University, wrote the chapter “Wireless
Wireless is a methodical account of the early development of wireless telegraphy and the inventors who made it possible. Sungook Hong examines several early significant inventions, including Hertzian waves and optics, the galvanometer, transatlantic signaling, Marconi's secret-box, Fleming's air-blast key and double transformation system, Lodge's syntonic transmitter and receiver, the Edison effect, the thermionic valve, and the audion and continuous wave. Wireless fills the gap created by Hugh Aitken, who described at length the early development of wireless communication, but who did not attempt "to probe the substance and context of scientific and engineering practice in the early years of wireless" (p. x). Sungook Hong seeks to fill this gap by offering an exhaustive analysis of the theoretical and experimental engineering and scientific practices of the early days of wireless; by examining the borderland between science and technology; depicting the transformation of scientific effects into technological artifacts; and showing how the race for scientific and engineering accomplishment fuels the politic of the corporate institution. While the author succeeds in fulfilling these goals, the thesis, it seems, is to affirm Guglielmo Marconi's place in history as the father of wireless telegraphy.
Research suggests that managers and employees in the wireless industry have faced tough challenges in their daily work. Managers have had the difficult job of crafting appropriate business strategies and human resource practices in the face of technological uncertainty, volatile demand, and heightened price competition in markets plagued by overcapacity (Batts, Colvin, Katz & Keefe (2005). This paper will examine the challenges facing the wireless industry the near future and recommend ways in which my new organization, Twenty1Wirless, can meet those challenges. First we will discuss the challenges we are facing as an organization. Next, we will explore the opportunities Twenty1 Wireless has to overcome these challenges. Finally, we will discuss

The widespread application of The Internet of Things (IOT) can not only change the extensive management mode in agriculture, but also develop the strength in epidemic control for animals and plants to ensure the safety of the agricultural products quality. So it’s of great significance to intensify research efforts on the application of IOT in agriculture and forestry. In recent years, IOT has been applied in some agriculture and forestry fields. Now we’ll give a basic overview of it.
A network is merely a series of interrelated components, sharing information, linked by one common lifeline, spanning across a large area. When most people think of networks in the computer sense, cyberspace and the internet are usually types of networks that come to mind. However, these are just small pieces that complete the network puzzle. Many other types of networks include Local Area Networks (LANs), Wide Area Networks (WANs), and also wireless networks as well. This paper will provide some insight into the development, objectives, and impact of various network systems.
Some patients with chronic illness sometimes need to be monitored closely by medical team. By having the patients attached with suitable sensors which can transmit data over the network, it is possible for the patients to have long-term monitoring without the need for a long and expensive stay in hospital.
The world has gone through a lot of changed as time passes by. With advancements in the technological field people are can communicate with ones from around the world without having to even lift a finger. To make things more efficient and more cost saving industries have made technology wireless. Wireless technology gives people the chance to get up from their stationary computer, or cord phone and able to freely move without restrictions. The IT, or Information Technology has become a standard and very critical part of today’s society. Wireless technology came from the basic just cellular usage to sensors in the medical field. Wires are now a thing of the past in today’s world with forever revitalizing technology.

Introduction: This is a 21th century, technology is the most important and improved thing of the human life. It makes life easier and faster. Development of faster sophisticated technology we have better and fast life. So all we are connect each other by computer network. There are two different way of network: Wired and wireless. Now day we can found network almost everywhere. Home, business, public place, Airport, Planes, hospitals, school, train everywhere we can found networking. Therefore, almost every sector of the economy that has affected by wired and wireless technology. Wired network and wireless protect both has security, But in general wireless network is less secure than wired networks. For proper security AP (access point) and its antenna should be right position. Also add a wireless access point or use a wireless router we can connect to network wirelessly. AS we using more and more of devices (smart phones, tablet and computers) rely on wireless networking, we have to improve our network security too.
In today’s technological culture the term Wi-Fi is omnipresent and almost every device intended to connect to the internet has corresponding hardware. In the following chapters the components of this transmission standard will be examined and the basic concepts explained. The specifications and changes to this standard are extensive and therefore only the most important aspects are considered. The information originates from the IEEE standardization committee and two independent and recently published books. The standard will be explained, followed by the historical details and the protocol changes over time. After this the actual use and functionality is described and in the end will be a look at future trends.
Wireless communication has created an ever-evolving need for devices that are faster and applicable to a variety of lifestyle situations. As new devices are created, security measures have to be implemented and policies have to be adapted as the way we live changes in response to the technology available to us. Two of the most common wireless communication access methods are Bluetooth and WiFi.
