The Bluetooth Solution

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.
