Wireless communication is defined as "electronic products and systems that interact by using electromagnetic energy, to carry information between them, so they can communicate with each other." (Wireless Technology Advisor). We use wireless communication to send information that is transmitted into the universe Wireless is a technology that transmits signal without using cables as the medium to communicate from one end to other(s) end. Communications via wireless can be anything from radio broadcasting, SOS signal from a ship at sea, or day-to-day Wi-Fi Essay On Wireless Communication • Individuals can work and access internet anywhere and anytime without carrying any cables or wires, anywhere there go. • It helps to complete the work anywhere on time, it improves productivity. • It is a solution in the areas where installation of the cables are
wireless communication networks - Essay - words
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. Wireless networking has proven to become a vital fragment in companies and homes. Wireless LANs has exemplified its advantage in mobility, productivity, convenience and deployment compared to wired LANs.
The Institute of Electrical and Electronics Engineers, Essay on wireless communication, has continually expanded upon the original The new standard for WLAN, The benefits of Wireless LAN has continually propagated as new stan middle of paper lacing traditional Wi-Fi. This will allow us to gain a more fundamental insight in the possibilities and restrictions of wireless LAN.
Generally, essay on wireless communication, wireless LAN proved to be a reliable and reasonably fast mobile networking solution. For most purposes, the bandwidth it provides should suffice, although cabled LANs offer more possibilities to extend the bandwidth.
In situations where mobility is as good a criterion as bandwidth, a wireless LAN should certainly be considered a serious option. Our Project demonstration is based solely on wireless internet technology. Basically, what we set out to do was to prove that a wireless internet connection could actually be made, and that it could made to be, at least somewhat, secure. Our goals are listed below: 1. Wireless Technology Wireless technology is an industry that has seen much growth and progress in the years following the inception of the internet and cell phones.
Our society has progressed to the point to where we can no longer function without this technology. Business, travel, and everyday life now are dependant on wireless essay on wireless communication. Wireless technology is just what its name implies, communicating or computing without wires and phone lines. Most Common Wireless Networking Access Methods 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 essay on wireless communication methods are Bluetooth and WiFi. The Personal Area Network PAN created can operate at a distance up to meters feet depending on the individual device specifications.
This can be a burden for small organizations that do not have a large information technology IT staff to keep them updated with the latest technologies Cisco, A significant way for employees to stay in touch besides cell phones, laptops and hand held computers is wireless local area networks WLAN. Also known as LAWN, a wireless local-area network uses high frequency radio waves rather than wires to communicate between computers or other devices Webopedia, Business owners are now recognizing the benefits of incorporating wireless network into their organizations.
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.
Wired ones are practically safer. So, it is important to secure the wireless network by utilizing small time to be saved in future, essay on wireless communication. The security of wireless networks becomes more vital because it is most commonly used in every field. Wireless Network Security 1.
Wireless Networking Basics According to Vacca, JR The term wireless networking means the technology that facilitates two or more computers to communicate using standard network protocols, but without network cabling. Wi-Fi is a technology that connects your computer to an internet access point using essay on wireless communication signals.
Also this technology is very similar to smartphones and TVs as they all use radio waves. Wi-Fi is a very important part of technology today as it allows people to connect with each other and to access information that was probably difficult to obtain before Wi-Fi.
Wi-Fi is just accessing the internet like you are directly connected with an Ethernet cable however with Wi-Fi you can access the internet wirelessly as long as you are in the routers radius. Wi-Fi is a very important part of peoples live and there are many companies that make a lot of money form just selling their Wi-Fi packages such as Virgin Media and BT.
Home Page Essay On Wireless Communication. Essay On Wireless Communication Good Essays. Open Document. Essay Sample Check Writing Quality. Introduction Wireless communication has improved dramatically in the last few years, essay on wireless communication. Their networks are indispensable providing the means for mobility, city-wide Internet connectivity, essay on wireless communication, distributed sensing and outdoor computing [10]. It essay on wireless communication the transfer of messages between people that are on the other side of the world.
Without wireless communications people would not have a lot of the devices many 21st century citizens could not live without, namely the smartphone. It is also required for devices using Bluetoothremote controls, Wi-Fi; really any electrical devices that communicate via a wireless or wired channel [1]. However, in the least developed countries only 89 out of the million use the internet. This is only a 9. These statistics inform us just how important the work in the field of wireless communications is.
Work will continue so that the less fortunate have more of a chance to get access to things like cellular networks and the internet. This will put pressure on maintaining the excellence of wireless essay on wireless communication in terms of rate, spectral efficiency and power consumption, essay on wireless communication. An attempt is made also to keep the data transmission system as essay on wireless communication and reliable as possible.
All of this has motivated researchers to integrate various wireless platforms such as cellular networks, WLANS and also, MANETs which is a mobile ad hoc network which continuously is a self-configuring, infrastructure-less …show more content… These are amplify-and-forward, decode-and-forward and compress-and-forward.
The amplify-and-forward AF is the most simple and quickest of the three. It acts as an analogue repeater and was introduced in Whenever this type of relaying receives a signal all that it does is amplify the received signal from the source and transmit essay on wireless communication to the destination. The destination receives two independently faded versions of the information so that it is able to make better decisions.
Obviously errors will occur using this strategy. No encoding or decoding takes place here and the noise gained by the signal from the source to the relay will also be amplified! The decode-and-forward DF, may also be described as digital regenerative repeaters strategy decodes the message received at the relay.
It performs very well here but when it does fail to decode properly, essay on wireless communication, an error propagation phenomenon is observed, essay on wireless communication. To counter this methods have been introduced where the relay detects and forwards the source information only is case of high instantaneous source-to-relay link signal-to-noise. Get Access.
