Wi-Fi

What is Wi-Fi?
It is wireless fidelity networks.
It is new, fast and easy way of going online - wirelessly. All u need is a laptop/mobile with 802.11b standard (will explain standards in the forthcoming blog of mine).

Wi-Fi networks consist of two key elements - a wireless access point router and a Wi-Fi enabled device.
The area where u can access Wi-Fi is called a 'hotspot'.

How Wi-Fi works?
A Wi-Fi hotspot broadcasts radio signals from antennas atop buildings, traffic lights, inside cafes, hotels and airports. An antenna has a range of about 300 to 500 feet. The antenna and router provide high-speed connectivity to the Internet.

Some of the hotspots in Chennai are Taj Coromandel, Sify I-Way, International Airport.

This was taken from an article I have read. This is to keep involved everyone in the latest technology.
