Bluetooth Network

Prepared By:Sara Ayad Aldehany

What is Bluetooth?

Bluetooth is a very simple type of wireless networking that can allow up to eight devices to be connected together in a mini-network.

It is very short range in operation, and so is considered to be for 'personal' networking. With a range typically under 30ft, this allows enough distance to perhaps communicate across your office, but not any further.

Bluetooth Applications

Bluetooth Overview

Bluetooth is designed to be compatible across a range of very different operating systems and devices (including things that you would not normally think of as being 'computer' type items )

for example, some types of headset. Bluetooth networking can enable the headset to connect with other devices such as your phone, your MP3 player, your computer.

Bluetooth can also help different devices to communicate with each other. For example, you might have a phone, a PDA, and a computer. If all three devices have Bluetooth capabilities, then (with the appropriate software on each device) you can probably share contact information between all three devices quickly and conveniently. And you can look up a phone number on your PDA (or laptop) and then place a call direct from the laptop or PDA, without needing to touch your cellphone.

How to communicate ?

Each device needs to have the appropriate software as well as the basic Bluetooth communication capability

Bluetooth Design and Development Tools

Design tools: RF and digital design tools, simulators, and other tools

Development tools: including modules, chipsets, RA and digital kits, protocol implementations and other tools

Testing/evaluation tools

Devices that Use Bluetooth :

Digital cameras and camcorders Printers Scanners Cell Phones PDAs Laptops Keyboards and Mice

Devices that Use Bluetooth :

Headsets In-car handsfree kits GPS navigation receivers Home appliances (microwaves, washers,

driers, refrigerators) In addition, add on Bluetooth adapters

are available for computers (eg with a USB interface) and for PDAs (eg SD cards).

Summary

Bluetooth promises to be a low cost, convenient, and simple way of enabling your various computer devices to talk to each other and to their peripherals. The reality has yet to match the promise, but Bluetooth is becoming more widespread and functional every day. Bluetooth is almost certainly in your future.
