Wi-Fi: Connect to the World

by Blaine Reynolds

Wi-Fi, short for wireless fidelity refers to a set of wireless networking technologies more specifically referred to as any type of 802.11 network, 802.11b and 802.11a, dual band. The word Wi-Fi was built by an organization called the Wi-Fi Alliance. They overlook tests that confirm the production.

A product that undergoes the alliance analyses is given the name "Wi-Fi certified". In earlier times, the term "Wi-Fi" was used only in place of the 2.4 GHz 802.11b.standard. It rapidly gained in fame with access points across the Unites States.

These standards are generally in used around the world, and allow users that have Wifi capable device, like a laptop or PDA to connect anywhere there is available Wi-Fi access point.

There are three standards referred to signify the speed of connection. Both the 802.11a and 802.11b are the ones capable of 54 MBPS with 802.11a additional capabilities.

802.11b are the most common of the three standards because it can transmit at 11 Megabits per Second even though the faster WI-Fi standards are quickly changing it. However, all these Wi-Fi standards are fast enough to generally allow a broadband connection.

Wireless Fidelity is an appearing technology that will probably be as common as electric outlets and phone lines in a few years. It adds great levels of convenience and high level of production for workers whose offices have a Wi-Fi access.

It is intentionally planned to be use for wireless devices but is now often used for Internet access. You can connect computers anywhere, in or out your home or office without needing wires. They are just connected to the network that uses radio signals. Even travelers can progressively equip Wi-Fi in airports, coffee shops, Internet cafes, malls, and hotels around the world.

How does W-Fi work?

Wi-Fi is the wireless way to handle networking. Wi-Fi allocates a worldwide Internet connection to be transmitted through radio waves. Radio waves are the ones that make Wi-Fi run and exist. They permit Wi-Fi networking occurs between many people. These waves are transmitted from antennae and Wi-Fi receivers are picking them up. The moment a device receives signal within the range of a Wi-Fi network, an Internet connection is produced without a chord and with the use of a Wi-Fi card that reads the signal. The user will be incited with login screen and password if needed once the connection is established between the user and the network.

How secure is Wi-Fi?

Wi-Fi maintains and continues to have numerous security issues. Wired Equivalent Privacy (WEP) is used in the physical and data link layers. It was planned to provide wireless security by protecting the data while it travels from one point to the other. Contrasting with the wired LANs, their networks are usually inside the building.

Even if it is protected by wireless LANs, they are more exposed due to the fact that the data travels over radio waves which are much easier to capture. One of the reasons why WEP is vulnerable, some other corporations do not even change their shared keys for a long time. The keys are too long to be used. With that much time, the key can get into other hands and use it in a wrong motive, which could be disastrous for the corporation.

Mobile Wireless Router Spotlight: WiFlyer Mobile

By: Dean Forster

With the introduction of wireless networks, people find it easier to install and configure a network. However, until a few years back, if you wanted to connect to the Internet or to connect to a network, you had to plug in a network cable and were restricted to stay near a UPT cable plug. If you wanted to move around, there were very difficult and expensive solutions. Engineers have developed a series of wireless devices able to transmit data around a building, but at very low speeds and huge costs. When the wi-fi standards had been established, people and organizations were given the opportunity to connect with one another without using any wires at all, at convenient costs and a decent connection speed in the same time. The technologies have evolved significantly. There are many devices that are wi-fi compatible that allow you to access the Internet from wi-fi spots and wireless networks: laptops, PDAs and 3g phones are just some of the mobile devices incorporating wireless chips. In fact, the networks have evolved so quickly, that they offer speeds similar to broadband connections.

Wireless equipment manufacturers design devices that are more and more advanced and this can be seen in their size. A mobile wireless router can be the size of a PDA. The WiFlyer router is a powerful device allowing you to set a wireless network in no time and to configure and secure it easily. You can connect between them all sorts of wi-fi compatible devices, such as modern laptops, video phones supporting wi-fi technologies and USB or PCI wireless network cards.

The WiFlyer mobile wireless router supports the latest 802.11 standards, the 802.11b and the 802.11g specifications. This translates to a speed of over 54Mbs and it is able to send and receive data for a radius of up to 200 ft (at these distances it supports a speed of over 11Mbs). If you are interested in securing your wireless network, the WiFlyer mobile wireless router supports 128-bit WEP protection to make sure no one accesses your network unauthorized. The WiFlyer is relatively simple to install and configure. All you have to do is to connect it to the main internet connection and it will automatically configure itself with the required settings. It also supports dial-up connections and it is able to share the available internet connection between several devices. It comes with an external power adapter, but it very compact (in fact it is smaller than the router itself), making the device a truly portable unit. In independent reviews, the WiFlyer mobile wireless router was able to send and receive data through concrete walls inside a bureau office, making it a viable solution for businesses and private networks.

Can I Build My WiFi Antenna?

By: David Faulkner

As the number of portable computing and communication devices grew, so does the demand to connect them to outside world. To go on line the computers had to be plugged into a telephone wall socket. Requiring a wired connection to fixed network meant that computers were portable, but not mobile.

To achieve true mobility the computers need to use radio(or wireless in that case) signals for communication. . In this manner, dedicated users would be able to read and send email while driving or moving to other rooms etc. A system of portable computers that communicate by radio are known as wireless LAN. Therefore to provide mobility to the systems, wireless local area networks were developed and now a new technology “Wi-Fi” or 802.11x(IEEE standard for wireless LAN setup), has become the most popular worldwide standard for the wireless communication in LAN..

Nowadays all major Laptop manufacturers provide an in built wi-fi system. Work is being done to make various devices like mobile phones, mp3 players etc to be wi-fi enabled.

In order to meet the growing demand for wi fi networks, various public places are provided with them.

In order to enhance the wireless capabilities the antennas are developed and are now available in the market, though they are easy to install but these antennas are very expensive. Hence it would be a great thing if it is possible to make our own antennas with some readily available goods. We would need a cable (also known as pigtail) to connect wireless interface card with the antenna. We would also need two kinds of connectors, a N-male connector to connect one end of the cable to antennas and an appropriate connector to connect the wireless interface card with cable. Since the making of antenna requires wire, we would also need a soldering iron to solder wires. For more info see http://www.topwifireviews.com/USB_Wi-Fi/ on USB Wi-Fi

ADVANTAGES OF DESIGNING OUR OWN ANTENAS

The construction of our own antennas provides various advantages to us. Apart from being cheaper than the antennas available in market they are also easy to configure into our system. So instead of investing huge amounts of money in antennas we can better manage that money by adding them to buy better Laptop systems.

There is also time factor involved in making our own antennas system. Since it is easy and faster to make and install our own antennas, it saves lot of time.Hence designing and making our own antennas would provide a better facility to the total cost involved in configuring the communication system
