The Evolution Of Wireless Networks
Could you imagine a world without the use of a wireless network? You wouldn’t be able to use any of your mobile devices such as your notebook computers, any of your tablets, or any other mobile device. Before there was any kind of wireless networks you had to be physically connected to a network using a network cable, something along the lines of a RJ-45 Ethernet cable (a cable used for transferring data).Having to be physically plugged into some kind of network port, this caused many problems, some of the problems it caused are as follows. First you had to be stationery, meaning you couldn’t get up and take it with you, and a fast paced world that we live in today who really has time to stay stationery for

In 2003 a new amendment was created that was called 802.11g. Just like the previous standards radio frequency, this one ran on the 2.4 GHz as well. This standards throughput would increase a little bit. For the throughput it was published to be 54 mbps but in all actuality it ran at about. According to PC Magazine “802.11g is full backwards compatible with 802.11b”, meaning they can run on the same radio frequency. Seeing how they run on the same frequency they have the same indoor and outdoor range of 802.11b which was 150 feet for the indoor range and the outdoor range of 300 feet.
In 2007 the Institute of Electrical and Electronics Engineers started to create a new standard. It wasn’t until 2009 until the new standard that was known as the 802.11n standard was officially established. With the world turning to more devices with wireless networks the IEEE had to come up with something to be able to transfer data at a faster rate and a longer radio frequency range. With this new standard it did just that. Cisco has actually stated that “The 802.11n standard can optimize your network by up to 6 times the performance from any of the earlier standards the radio frequency that this standard uses is both 5 GHz and 2.4 GHz. An article from Intel said that “802.11n quadruples the throughput performance than the original standards with up to 600 mbps but on average about 200 mbps”. Consumers were amazed by how fast the

You wouldn’t be able to connect to a network with your mobile devices. Also some medical supplies run solely on wireless so those devices wouldn’t work. There are many other things you will need to connect to a wireless network but this paper was about the evolution of it. The IEEE is actually always looking for ways to improve their wireless network standards. We are up to 1 Gig of throughput performance as of 2014 but as time passes more advanced technology will come about and data throughput can only grow from here.

Wireless networks – While the term wireless network may technically be used to refer to any type of network that is wireless, the term is most commonly used to refer to a telecommunications network whose interconnection between nodes is implemented without the use of wires, such as a computer network. Wireless telecommunication networks are generally implemented with some type of remote information transmission system that uses electromagnetic waves, such as radio waves, for the carrier and this implementation usually takes place at the physical level or “layer” network.
Broadcasting involves specific rules and regulations that must be followed. The paramount justification for regulating broadcast is the scarcity rationale. The radio spectrum is extremely large, and cannot assist the needs of everyone who wants to broadcast. The spectrum as a whole relies on the government to manage and operate it. It is up to them to decide what broadcasters will best serve the public. A scarcity rationale case, NBC v. United States arose when regulations and restrictions were put on radio stations that were to protect “public interest.” Radio Networks proceeded to test the guidelines and licensing laws, resulting in the FCC gaining strong power over regulations of the radio spectrum. Although the Communications Act provides equal opportunities to all candidates with equivalent broadcast time, it still did not confine the FCC from having overall control.
With all the technology today, the Internet is still off-limits to certain people. Everyone does not own a computer and because of this, everyone is not computer literate. Mostly middle and upper class people have their own laptops, or computers, and are able to pay for Internet service. Other people, like student's who use their schools computers or people who go to libraries, are forced to use whatever equipment is available, which is, in most cases, not top of the line and sometimes may or may not have the Internet. Soon this world will be computer-based and if you do not have your own computer or at least access to one, you will be behind. The Internet is an important part of computers considering the many uses it offers.
You have probably taken advantage of Wi-Fi access when traveling, at airports, in your hotel room, shopping, enjoying a latte at your favorite coffee shop or even waiting for your doctor to see you. In today’s world, Wi-Fi is an important feature whether you are in the hospitality industry, (free, high speed, in-room Internet access ranks as the most desired guest-room amenity), at an event (free Wi-Fi affects the choice of venue ), or in an office/hotel lobby, bar, restaurant or conference room. As a business owner or IT manager selecting the right wireless solution can have either an adverse effect on business or be a highly beneficial

The propose research will address a problem confronting many two year institutions in the present-day (i.e. how to best plan, design, and implement WLAN technologies). While WLAN technologies offer the benefits of mobility, reduced installation time, and decreased cost, many challenges must be met by institutions deploying them (Geier, 2005). These issues are related to security, speed, interoperability, and equipment selection, ease of use, reliability, signal interference, installation, and health risks.

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.
Days, months, and years go by and we do not notice them. Living in such a busy world, we are not always aware of the changes in our lives. Twenty years ago, if someone was told we would be able to buy groceries, pay our bills, buy stocks or even a car through the use of a computer, we might have laughed and blamed too much science fiction television for such wild accusations. However, as the next generation of children grows up, they may find it funny that people still send letters to each other through the post office. The development of the Internet has given us the ability to communicate and exchange information instantly across vast distances. The Internet has caused a huge impact in the communication field, and has made our way of living and working a lot easier, faster, and cheaper than before.

Often companies will even discontinue their business meetings and will participate in a video conference, for example two businesses will meet to discuss the purchase of a product. In essence this will take away the personal time and could rush a purchase, and cause the company to deny a deal.
The presence of computers, phones, internet and wireless devices have broadened the web of connectivity by changing long distances to short ones where everyone is equal distance from the other through the present connections. Leaving without technology will be totally impossible as this has become every day’s application as more and more people are gaining knowledge on how to make use of the communication tools to improve their ways of living and staying informed on the current technology to avoid being left behind. New technologies are being developed daily which shows that the industry will continue to grow and expand. People will continue using these technologies to improve their standards and to stay informed
Wherever you look you can find a transportation device, when you go out you can find a car, a bus or even a plane flying over your house, almost everyone in the world uses one of these on a daily basis, whether it is going to the grocery store or work.
