Just like everything else in the world, Wi-Fi has its set of advantages and disadvantages. Below is a low down of how Wi-Fi may or may not work for you.
The biggest thing that attracts people to Wi-Fi is that one can find a wireless connection almost everywhere, in larger cities at least. This aspect makes mobile computing a reality.
Aside from that, one can connect to a Wi-Fi network for free or for a minimal fee. There are coffee shops and restaurants that offer this connection to their patrons in exchange for a minimum purchase.
Also, there are cities and municipalities where Wi-Fi is offered for free. This service is often offered by local governments although sometimes they also work with broadband providers to create the infrastructure for this.
Then theres Wi-Fis downside. First of all, its range is very limited. Unless an area has several hotspots, one has to be as near the source of the signal as possible. Otherwise, the connection would be terrible.
Even the next generation of IEEE802.11 protocol, the 802.11n, can only offer a range of 250 m outdoors.
There are also security concerns regarding the use of public Wi-Fi networks....
