What is a Network?
In classic computer terms a network is something by which a bunch of computers are hooked together so they can share things. These “things” may be a connection to the internet, a printer or scanner, maybe also data like document and picture files. Now days these “computers” can come in many forms, the classic desktop PC, a laptop, a tablet, your phone, television and even your watch can all be computer devices that can connect to a network.
What is a Wireless Network?
A wireless network is where devices use radio waves to connect to a network. It is usually pretty easy to wirelessly connect to a local area network (LAN) that is set up at your home or place of work. You can connect to a business’s wireless network if they provide a “WiFi hotspot”. Many cafés, hotels and airport lounges do this. My favourite place to visit when travelling tends to be a multinational fast food outlet, not because I like the fare in particular but they usually have a free WiFi hotspot. Internet services can also be supplied directly to households and businesses over large areas using wireless.
Wired vs Wireless
Traditionally computers were networked with each other using cables. This still happens in many instances where large amounts of data are required to be transferred through the network. Once there was a large difference between wired and wireless. Speed was a big factor with wire carrying data much faster and security was another reason that wired networks were favoured by business in particular. The gap has rapidly closed however and will close further with continued enhancements made to wireless technology. There are less reasons to hard wire your network than ever before.
Why go Wireless?
It’s easy. No more need to run cable everywhere you need a connection. I for one will not miss crawling through dusty, hot confined roof spaces to run wires.
Coverage – go mobile. With wire you are tied to that wall socket, now you can drag your tablet into the back yard or someone else’s office and stay connected.
Expand. With WiFi range extenders and bridges you extend a wireless from your office to the poolside and even your office across town.
Cost. Don’t like running cables? Neither do electricians, so they will charge you well for the pleasure. A wireless network can be set up with one relatively cheap device.
The future is here, with smart phones and pads even Dick Tracey style watches and glasses all capable of becoming “connected”. Two of the world’s most flamboyant entrepreneurs, Richard Branson and Elon Musk are currently in a space race to provide the whole world with wireless internet via low earth orbit satellite. No more cables, wires or even fibre optic. Great news for those folk in remote areas. Wireless is here and won’t be going anywhere soon. Are you ready to get “connected”?
