Wifi Hotspots

If you have a computer and live in the city then you have seen people sitting in café’s searching the internet on their own computers all over town. You might be thinking to yourself, I don’t see any wires connected to their computer, how can they be connected to the internet? Wifi is the answer.

Wifi is a relatively new technology that enables a person with a computer (usually laptop) with a Wifi card to send and receive information through the air. Most Wifi cards can send and receive signals within a short distance of less than 100 feet, but that is usually enough for patrons to enjoy their coffee and check their email at the same time.

There is new technology that will be out shortly that drastically expands the reach of the Wifi signal to more than half a mile. This can help bring more people onto the internet without the expense of laying heavy infrastructure underground.

Many smaller to mid size cities are now planning on adding Wifi throughout the entire city. Just recently Philadelphia has made a deal with a telecommunications company to cover the whole city with Wifi signals. Other cities such as San Francisco are looking to cover their entire city with Wifi signals as well.
