Bluetooth wireless hotspots

Bluetooth is the name of a wireless technology standard for connecting devices in a way that have already started to replace cables. This is a technology of the future as more and more networks are likely to be connected through bluetooth in the days ahead. As a result, networks would finally be able to break free from the clutches of cables. But more importantly, this would enable people who are in this network to finally become mobile.

But the problem is, this is still not possible from anywhere. It works only at places and these places are popularly referred to as wireless hotspots. Though these hotspots can be extended with the help of routers and antennas, but to a large extent the reach of the wireless hotspots are still limited.

The technology uses radio frequencies in the 2.45 GHz range to transmit information over short distances of generally 33 feet, which is 10 meters or even less. By embedding a bluetooth chip and receiver into products, cables that would normally carry the signal can be eliminated.

There is an interesting story behind how this came to be known as 'Bluetooth'. Bluetooth is named after King Harald Bluetooth of Denmark, who in the 1930s consolidated warring factions of Denmark, Norway and Sweden into a force to be reckoned with. His ability to establish peace between differing peoples has been used as a metaphor for the ability to connect devices from differing technologies.

With the spread of bluetooth wireless hotspots in the years to come, all sorts of devices like the cell phone, headsets and earpieces, digital cameras and computers will easily be able to communicate with each other and work together without cables or the need for complex setups.

Experts feel that this is how bluetooth devices that have to work with one another will work in the future. They will initiate their own separate PAN and synchronize a random hopping scheme to create interference free communications. Known as spread-spectrum frequency hopping, the devices will jump among 79 random frequencies within a specified range, changing about 1,600 times per second in perfect unison.
