The technology of Bluetooth will take small area networking
to the next level by removing the need for user intervention and help keep
transmission power very low to preserve battery power. Each transmission signal to and from your
cellular phone will use just 1 mw of
power, giving you plenty of space on
your battery to talk.
Bluetooth is a networking standard that will work on two
levels:
1. It will provide agreement at the physical
level, as Bluetooth is a radio frequency standard.
2. It will provide agreement at the level of
protocol, where products will have to agree on when bits are sent, how many are
sent, and how the parties in conversation can be sure the message recieved is
the same one that was sent.
The major draws to Bluetooth is the fact that it's wireless, inexpensive, and automatic.
There are other ways to get around wires, including infrared. Infrared uses light waves of a lower
frequency than the human eye can, and is normally used in television remote
controls.
The technology of Bluetooth is intended to get around the
problems that normally come with infrared systems. The 1.0 older standard of Bluetooth has a max
transfer speed of 1 MB a second, while the 2.0 Bluetooth standard can manage up
to 3.0 MB a second. To make things
better, 2.0 is compatible with 1.0 devices.
As a solution to wireless, Bluetooth will eliminate the need for messy cords,
keeping everything nice and neat. It's perfect for those who like to talk on
cell phones, as you no longer need to hold the phone next to your ear - which
is great for those who travel a lot.
