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
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 there’s Wi-Fi’s 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. Since these networks are
intentionally or unintentionally unsecure, malicious users
can sniff the data of other people sent and received by
others in the network and use it for criminal purposes such
as identity theft.
But this can be addressed by having an antivirus program
and a firewall installed on an individual’s computer.
