The internet is actually not all that cheap to use of you are living in a poor nation or even in a developing country, using the internet means having to pay quite an amount of money. The main reason why this is so is because of the basic lack in infrastructure that causes this shortage of ease of availability of easy networking, and so this problem of expenses arises. Also, there is the problem of having to use very expensive hardware and software which automatically ups the price of the internet technology in such countries.
This problem could be termed as the problem of the digital divide and to counter this the easiest thing to do is to device some sort of a wireless network solution, and the best answer to this is the Wi Fi technology. Wi Fi is thus spreading at a tremendous speed in such country for easy usage of the internet. Such a wireless mode of networking has some clear cut advantages such as the following.
For instance, Wi Fi can easily be connected through rooms and even buildings and other huge spaces without the requirement of a cable of any sort. They use radio waves to form the network and such a system comes in very handy as the wireless network can actually be constructed around a large space and thus be very useful. The Wi Fi network usually has an access point like a hotspot box for instance and all other computers and laptops etc can all access the internet connection through wireless connectivity through this hotspot. Modem, proxy, gateway card etc are all the wireless clients that make it possible for the radio receptions for the network to be received. The software used to make the Wi Fi connection is very easily available, you can use a card that would slide into a slot in the laptop or on your computer and can be installed very easily or the connection can also very easily be made using an adaptor and can be connected using an USB cable and so that entire process of setting the Wi Fi connection up is also very easy to do and can be taken care of.
If you can develop a Hotspot in an open kind of an area, then all kinds of laptops and internet connections can be made by anybody in the vicinity. So it works great for business places like the Mall etc. where people will turn up more if they can use a free internet connection.
