Wifi is short for wireless fidelity. WiFi has gained acceptance in many environments as an alternative to a wired LAN. Many airports, hotels, and other services offer public access to WiFi networks so people can log onto the Internet and receive emails on the move. These locations are known as hotspots.
However wifi network puts restrictions â€“ you must be within the range of the WAPs, the wireless end user has a full network connection with the benefit of mobility. One IEEE 802.11 WAP can typically communicate with 30 client systems located within a radius of 100 m.
A Venezuelan techie apparently has set a new record for longest WiFi link. Networking guru Ermanno Pietrosemoli established a wireless connection between a PC in El Aguila, Venezuela, and one in Platillon Mountain, a distance of about 237 miles, mostly using off-the-shelf equipment and a few hacked parts.
