Much like everything else in the world, Wi-Fi has its own set of advantages and disadvantages. Below is a low down of how Wi-Fi may or may not function for you.
The greatest thing that attracts people to Wi-Fi is that one can locate a wireless connection just about everywhere, in larger cities at least. This prospect makes mobile computing a reality.
Apart from that, one can connect to a Wi-Fi network free of charge or for a minimal fee. There are cafes and restaurants that offer this connection to their patrons in exchange for a minimum purchase.
Additionally, there are cities andmunicipalities where Wi-Fi is offered up for free. This service is often provided by local governments although occasionally they also work with broadband providers to produce the infrastructure for this.
Then there’s also a Wi-Fi’s downside. Firstly, itsrange is rather limited. Unless an area has numerous hotspots, one has to be as close to the source of the signal as possible. Otherwise, the connection will be terrible.
Even the following generation of IEEE802.11 protocol, the 802.11n, could only offer a range of 250 m outdoors.
There are likewise security concerns involving the use of public Wi-Fi networks. Since these networks are purposely or unintentionally unsecure, malicious users can sniff the data of others that are sent and received in the network and use it for criminal purposes like identity theft; but this can be covered by having an antivirus program and a firewall set up on an individual’s computer.
