Five Reasons to do Wireless Networking

I believe that wireless networks represent one of the most significant inventions in human history – almost as important as sliced bread.

Now, seriously, bread is certainly easy enough to cut yourself, but try to wire up a network and you will think of this invention in a different way.

Just to make the whole picture clearer for you, let me give you five reasons why using a wireless network is definitely worth it.

Sharing Web Access

With wireless networking, you can easily and cheaply share one single Internet connection among different computers, without having to use more modems. If that wasn’t enough, you can even include new computers in your network only by using a wireless card and switching them on to have an immediate Internet connection! Not many wired networks would be able to do that.

Sharing Printers and Files

A wireless network guarantees access to your files regardless of where you are within your house, and with a home computer it also facilitates the synchronization of data on a laptop. Using wireless networks makes it so much simpler to send files between computers as compared to the traditional emails or CDs.

Moreover, if your printer is connected, you can write your documents anywhere you want and finally print them through a printer connected to another computer. In other words, a printer plugged into one of the computers on the network is available to all the computers saving you the expense of having multiple printers at home.

Playing Games Online

As might have already seen, games have often the option to play over a LAN. As previously mentioned, wireless networks are LANs, meaning that people can play together without having to be physically near each other.

Isn’t it more exciting to play with your family and friends instead of unknown people on the Internet and be able to make the whole game work much faster? Actually, you can even ask your friends to bring their own computers in and join a thrilling 'LAN party'!

With wireless networking you can easily connect any games you wish to play to the Internet, and start playing online. Playing online with a wirelessly connected to Xbox or PlayStation 2 is definitely simpler than having to use your modem for connection all the time.

Always On Access

What made the spread of broadband possible was that it let Internet connections be constantly on, eliminating the need of dialing in all the time. With wireless networking, network connections are always on, so that every time you wish, any of your computers is able to connect to the Internet!

Regardless of where you take your laptops to within your home, they will have instant access! Moreover, wireless networks offer you the convenience of eliminating usernames and password systems, as they operate without logging in. Talk about convenience!

No More Wire Running Everywhere!

Being able to eliminate wires from running all over your house is probably the biggest reason why you should turn your network to wireless. Believe me, you will be so pleased when you get rid of problematic, costly, ugly and unsafe wires.

Although the average Ethernet wire doesn't cost much, once you've bought the necessary quantity to do what you need to do, but getting everything you need for a wired LAN it adds up quickly.

Plus, whenever you wish to have wires running between rooms or floors, you are forced to have holes in the walls, which might not even possible if the house is not yours.

Many people living in rented apartments have to limit their network to a particular room until they finally decided to switch to wireless allowing them to even take their computers outside, if they wish to!

Using wireless networks also enables you to have more safety, as there is no danger of tripping over uncovered wires.

Furthermore, if you are moving, you do not have to pack all the wires up and re-connect them again. Finally, with wireless networks there’s no need for you to check every single wire if your Internet connection doesn’t work.

Personal Wireless Networking

If you've got a wireless network for your computers already, well, you might get a bit excited about what I'm going to say next. How would you feel if your PDA, your mobile phone, your mp3 player and almost everything else you connect to your computer could be wireless too? You'd like that? Well, it's already a reality and has been for some time now.

Bluetooth is wireless and automatic, and has a number of interesting features that can simplify our daily lives. Bluetooth is a standard developed by a group of electronics manufacturers that allows any sort of electronic equipment -- from computers and cell phones to keyboards and headphones -- to make its own connections, without wires, cables or any direct action from a user. Read on...

Personal Area Network.

Using wireless networking with your personal gadgets is often called PAN, which stands for Personal Area Network. The idea is that, in the future, we'll all have laptop computers with their batteries charged and no more need to connect any wires to them at all -- you just place your Bluetooth device near the computer, and the computer sees it and can use it straightaway.

Bluetooth has been around and in-use since 1999, and it's only getting more popular. It was designed to be secure, low cost, and easy to use from day one.

There are two classes of Bluetooth that are in popular use: class 1 and class 2. Class 2 is the most common and cheaper standard, allowing you to use a device that is up to 10 metres (32 feet) away. Class 1 is rarer, but you can still find devices that use it easily enough, and it has ten times the range: 100 metres or 320 feet.

How Does It Work?

Bluetooth is more flexible than 802.11 wireless networking, in exchange for the shorter range. Essentially, a Bluetooth-enabled computer has one Bluetooth receiver installed in it, and this receiver can then be used with up to 7 nearby Bluetooth devices. On the other end, wireless devices do not need to have Bluetooth installed if they support it -- it is already integrated.

Like 802.11, Bluetooth works by using radio signals to create bandwidth. It is not, though, the same thing as an old-style wireless mouse or keyboard, which required a receiver to be plugged into one of your computers' ports, and didn't have range or stability anywhere near that of Bluetooth.

Many computers now come with built in Bluetooth, especially Apple Macs. If you want to add Bluetooth to a computer that doesn't come with it pre-installed, you should probably use a USB to Bluetooth adapter, although internal Bluetooth devices to install in your computer are available. If you have a laptop and a spare PCMCIA slot, you can get Bluetooth cards for that too.

What Can You Do With Bluetooth?

Mobile phones with Bluetooth are very popular, and so are PDAs -- the instant synchronisation of addresses and calendars to a computer is a useful feature. Other than that, almost anything that would usually use USB can be done using Bluetooth, including digital cameras, mp3 players, printers, and even mice and keyboards. If you take a look through the comprehensive list of Bluetooth 'profiles' (kinds of devices that could, in theory, be Bluetooth enabled), it includes cordless phones, faxes, headsets, and even video.

Basically, more than anything, Bluetooth is a replacement for USB: some say that while 802.11 wireless networking is wireless Ethernet, Bluetooth is wireless USB.

Not Just for Computers.

Part of the power of Bluetooth is that it isn't just used to connect things to computers -- it can be used to connect almost anything to anything else, if both things are Bluetooth-enabled and recognise each other.

Mobile phones, in particular, take advantage of this. Hands-free headsets often use Bluetooth to communicate with the phone. Some cars, for example, now have on-board computers that will connect with a Bluetooth phone and allow you to make hands-free calls, regardless of where the phone is in the car (even if you've left it in your bag in the trunk!)

On top of that, of course, Bluetooth devices can communicate with each other. This has led to some people sending messages from their Bluetooth PDAs to others in close range -- not an especially useful feature, but quite fun. This is called 'bluejacking', and the first recorded instance of it was a man who sent a Bluetooth message to another man's Nokia phone while they were in a bank together. What did the message say? 'Buy Ericsson'.

Since then, it has become possible to send images by bluejacking, and it is widely believed to be the newest advertising medium -- yes, it lets billboards send messages to your phone, a practice known as 'bluecasting'. Whether you think that's cool or annoying, of course, is your choice.
