How Does Wireless Internet Work?

Remember the days of dial-up Internet where you had to have your desktop computer plugged into a router and listen to the telephone line be hacked? Connections would be slow and intermittent and would always interrupt an important phone call or cut out right in the middle of that vital e-mail you were writing. Well, gone are the days of the busy signal and crackle of a pending connection. It’s hard to even remember that with all of the new connections available, from cable connections, satellite connections and the newest .
The wireless connection is a still a relatively new concept, despite how widely accessible and used it is. What most people are unaware of is how it works. Upon installation, most people just have the provider hook it up for them and they never have to worry about it unless they have to use the troubleshooter for a dropped connection. Internet allows us to have the high speeds no matter where we are; at work, at home, school or even while on the road, if it is available for your cell phone or PDA. The connection is not as complex as it may sound, though. It is similar to that of the wireless router you may currently have set up in your home.
There is a router that will receive a signal from your DSL or cable modem currently set up and it takes that signal and sends it through the airways to be picked up by the connection installed to your home or office computer, no matter if it’s a laptop, netbook, desktop or even personal device like a Blackberry. The signal is sent out through a mobile tower not unlike the gigantic, often tree-disguised cell towers. The best part about the connection is that the mobile signal does not weaken the further away you move from it, which is very different from that of a normal high speed wireless Internet connection.
With the old Internet connection, as your move away from the wireless router the signal will weaken. With the newer connection, if the mobile air card is installed the signal will not weaken as you get far away from it. The card also sends signals back to mobile tower to make sure it stays strong. Many newer versions of cell phone and netbooks already have , or at the very least the cheaper 3G option, installed on them. For laptops, however, all that needs to be done is purchase a mobile Internet card and use the driver to install it onto your computer. After it’s been purchased and installed, to make it work all you need to do is plug it into the USB port on your computer. If your phone does not have access to the connection, the card is available for installation on phones, even if you installed it on your computer.
