Making Life Simple With Wireless Technology

Wireless fidelity , or WiFi, is an amazing technology that allows you to network your computers, office, home, etc. without the need for wires. This makes networking so much easier and less messy because wires are not used. The computers simply connect to the network via radio signals.

Because of this easiness, many businesses, schools, malls, restaurants, cafes, stores, airports and other businesses have set up wireless hot spots that allow anyone to log onto the network. This is amazing for individuals that need to be able to work from any location, however there are some disadvantages because hot spots can be used by unauthorized users if not adequately protected through different security safeguards.

Hot spots are relatively new, but are growing in acceptance and popularity because of the incredible access it gives to students, travelers, business people and the like. Some hot spots are free, while others charge an hourly rate.

These days, if you go to an airport or hotel you will see signs that say internet zone or hotspot and will either say free or how to pay. Because of this evolution, individuals are able to work and study wherever they are, which makes traveling and working much easier and less downtime which is very important.

Wireless networking can also be installed in your home, which means you can work in any room in your home or even outside if you so choose. Many individuals are starting to realize how much easier this makes their lives and are installing the equipment necessary for a wireless network.

To get started, you will need an Internet connection, a router, and then wireless cards for your respective computers. The router allows the Internet signal to be routed throughout the home and the wireless cards that each computer has picks up the signal which eliminates the use of wires. All of this equipment can be purchased in your local computer store or online if you are looking for extra discounts.

If you are interested in installing a wireless network in your home, office, or business, then you can do some research online and install it yourself if you know even a little bit about computers. However, if you have a lot of computers you want to connect or are unsure of what you are doing, then you might consider hiring a professional to handle your wireless solution for you.

Once you have the wireless network setup anyone in your “hotspot” will be able to log onto the server as long as they are within range. However, if you want to exclude just anyone from logging on then you can use a virtual private network, Internet Protocol Security, or other security programs that will protect unauthorized users from logging onto your network.

How Do Wireless Networks Work?

Wireless networks work using radio waves instead of wires to transmit data between computers. That’s the simple version. If you’re curious to know what’s going on in more detail, then it’s all explained in this article.

Ones and Zeros.

I’m sure you know that computers transmit data digitally, using binary: ones and zeros. This is a way of communicating that translates very well to radio waves, since the computer can transmit ones and zeros as different kinds of beep. These beeps are so fast that they’re outside a human’s hearing range — radio waves that you can’t hear are, in fact, all around you all the time. That doesn’t stop a computer from using them, though.

Morse Code.

The way it works is a lot like Morse code. You probably already know that Morse code is a way of representing the alphabet so that it can be transmitted over radio using a dot (short beep) and a dash (long dash). It was used manually for years, and became a great way of getting information from one place to another with the invention of the telegraph. More importantly for this example, though, it is a binary system, just like a computer’s ones and zeros.

You might think of wireless networking, then, as being like Morse code for computers. You plug a combined radio receiver and transmitter in, and the computer is able to send out its equivalent of dots and dashes (bits, in computer-speak) to get your data from one place to another.

All About Frequencies.

You might wonder, though, how the computer could possibly transmit enough bits to send and receive data at the speed it does. After all, there must be a limit on how much can be sent in a second before it just becomes useless nonsense, right? Well, yes, but the key to wireless networking is that it gets around this problem.

First of all, wireless transmissions are sent at very high frequencies, meaning that more data can be sent per second. Most wireless connections use a frequency of 2.4 gigahertz (2.4 billion cycles per second) — a similar frequency to mobile phones and microwave ovens. As you might know, though, a frequency this high means that the wavelength must be very short, which is why wireless networking only works over a limited area.

In addition, wireless networks make use of a technique known as ‘frequency hopping’. They use dozens of frequencies in the range they are given, and constantly switch between them. This makes wireless networks more immune to interference from other radio signals than they would be if they only transmitted on one frequency.

Access Points.

The final step is when it comes to all the computers on a network sharing Internet access. This is done using a special piece of wireless equipment called an access point. Access points are more expensive than wireless cards for one computer, as they contain radios that are capable of talking to around 100 computers at the same time, and sharing out access to the Internet between them. Dedicated access points are only really essential for larger networks, though — if you only have a few computers, it is possible to use one of them as the access point, or you could just get a wireless router.

They Understand Each Other.

That’s all well and good, then, but how does wireless equipment made by entirely different companies manage to work together when this is all so complicated? Well, the answer is that there are standards that all wireless devices follow. These standards are technically called the 802.11 standards, and are set by the IEEE (Institute of Electrical and Electronics Engineers). It is thanks to people sticking to their standards that wireless networking is so easy and cheap to use today.

 

Tips to Fix Unreliable Wireless Connections

Generally speaking, wireless computer connections are reliable. However, nothing is perfect, and sometimes you may lose your connection or experience a weak signal. There are many factors that impact the reliability of your wireless connection. For example, if your wireless adapter is too close to a 2.4 GHz wireless telephone, you may notice a decrease in your computer’s wireless single strength. Why? Because the phone and the computer reside on the same frequency and can interfere with each other’s performance.

Handy Repair Checklist for Wireless Interruptions

1. First check to see if your cable or DSL is actually working. Usually located in your basement, most modems have four lights. You have a live Internet connection if the “data” or “status” light is on. If it’s off, or flashing, your cable is out.

2. If your cable/DSL is working, then reboot your computer. Sometimes, if your cable/DSL goes out for even 10 seconds, your computer and the wireless router may no longer be able to talk to each other. By rebooting your computer, a new IP address is assigned, allowing them to once again communicate.

3. If your desktop is wireless and you’ve moved the wireless adapter [the box that sits next to the computer with antennas], then you may need to move the adapter until you find a stronger signal.
