applications in any field are designed mostly based on the latest technologies. The wireless network is the most used technology in any field. The wireless networks had bought drastic changes in the human life. With recent developments in the wireless networks field, new and innovative medical applications based on this technology are being developed in the research as well as commercial sectors. This trend has just started and we predict wireless networks are going to become an integral part of medical solutions
Wireless technology has had a great impact on how we carry out our day to day activities. We no longer have to be at a specific point in order to receive information. Today we can receive information on the go making us more efficient and flexible. The greatest effect wireless technology has had in our lives is the effect it has had at our work places. Today with wireless technology you do not need to be at your desk to receive work emails. The smart phones allow us to receive emails wherever we
volume terms. Wireless Sensor Network is an emerging field which has found varied applications, especially for the Military. Applications using Sensor Networks, including underwater sensors need to be explored and developed further. Competitor Landscape The Global market share is quite distributed over many companies. No company has an overall Monopoly. A consolidation wave is expected to continue in the sensor markets, with Amphenol (APH), TE Connectivity and Sensata Technologies among the strategic
Competing Wireless Technologies - 802.11 vs. 802.16 vs. 4G mobile telephony IEEE 802.11 commonly known as Wi-Fi is a set of media access control and physical layer specifications for implementing wireless local area network computer communication in various frequency bands such as 2, 3, 3.6, 5 and 60 GHz. 802.16 however is a group of broadband wireless communications standards for metropolitan area networks developed by a working group of the IEEE. On the other hand 4G mobile telephony is the short
Abstract—Wireless sensor networks (WSN) is a key innovation for the wireless network technology. It generally has a large number of sensor nodes with a power unit, a sensing unit, a processing unit, a storage unit, and a wireless transmitter & receiver. They are more vulnerable to attack then wired ones due to its nature and resources limitations. So as to overcome this security problems we can different types of Key Distribution and Hierarchical WSN. This paper gives more solutions to all problems
computing and communication technologies. And a new technology evolves which is known as Wireless Sensor Networks (WSNs). Wireless Sensor Networks are a new kind of distributed systems that are an integral part of the physical space they inhabit. The massive growth in this technology has gathered the heed and imagination of many researchers, providing a broad spectrum of ideas to be implemented in various applications [2]. The grouping of various sensor nodes makeup a huge Wireless Sensor Network (WSN)
challenge in a wireless system design is to overcome the eects of the wireless channel, which have multiple transmission paths and dierent delays. OFDM has a promising future as a new technology in several next generation wireless communication systems. The OFDM systems ability to combat the eects of multipath propagation with a relatively simple receiver structure made it the modulation of choice for some of the most prominent wireless technologies such as the IEEE 802.11 wireless local area
Battery Span and Talk time Having a wireless hearing device does put you in an advantageous position as the user does not have to sit in one position and use it. Instead, he can move about and use the headset in a comfortable manner. However, if you end up with a wireless headset that does not have a good battery life; you would be spending half of your day in recharging it. The users of Plantronics Voyager Edge definitely do not fall in this category and they do not have to go through the trouble
Wireless Sensor Networks (WSNs) present universally and growing rapidly due to its unique features, such as their less weight, cheap, and wireless nature. However, due to its highly constrained computational and energy resources this network is exposed to numerous attacks that affect its security. So, it is important to address these security issues from the beginning of the system design. but, due to inherent resource and computing constraints, security in sensor networks poses diverse challenges
communicate with people who have more access to technologies. Every part of the globe is now probably covered with wires that stretch for millions of miles. After this, the next stop was to make communications possible with wireless technology.1 Innovations in communication, particularly the development of wireless technology, have allowed people to reach out to virtually anyone wherever they are on the planet. The great thing about wireless technology is that they make it possible to talk to someone
