Getting Broadband access over wifi
These days getting broadband access over WiFi is pretty simple and more and more affordable. Firstly, lets look at what WiFi actually is.
WiFi stands for Wireless Fidelity and it is away of transmitting information using radio waves, the same way that your cell phones and television do except more sophisticated. Most PCs and laptops come with a wireless adapter these days, or if you dont you can by a wireless network adapter to use externally. This wireless adapter will translate data and transmit it using an antenna to a wireless router which is connected to the internet using an Ethernet cable. This process works in reverse as well.
So as you can see, in order to get broadband access over WiFi you need these things:
1. A PC or laptop with a wireless adapter
2. A wireless router (these usually come with the necessary Ethernet cables)
These days it is not a hard to meet these requirements because the wireless adapter is inbuilt into most computers and wireless routers are easily purchased or often free when you go into a broadband contract with your Internet Service Provider.
If you have many computers in your home you have a few options in how make use of WiFi. If your computers are already networked using cables, you can create a wireless network using a wireless access point. Then only one computer needs to have a wireless adapter. On the other hand, if all of the computers have wireless adapters and you want to ditch messy cables you can create a network using your wireless router. This router will connect to your broadband port and will allow everyone to access the internet via WiFi.
Most routers cover about 100 feet and it is good to be aware that anyone in that 100 feet can access your internet unless you protect it. There are several ways to do this but the most common for homes is to use a WEP network key which is a long numbered password that you have to enter in order to connect to your router. If you dont take these precautions you may find that your neighbours are able to connect to your internet and download to their hearts content while you have to pay for it.
Security is an important part of a home wireless network, as well as public WiFi hotspots. If you set your router to create an open hotspot, anyone who has a wireless card will be able to use your signal. Most people would rather keep strangers out of their network, though. Doing so requires you to take a few security precautions.
WiFi is a very accessible technology these days, and most routers will come with instructions that will talk you through setting up the network and the security.
