Bluetooth is a new standard developed by a group of electronics manufacturers that will allow any sort of electronic equipment -- from computers and cell phones to keyboards and headphones -- to make its own connections, without wires, cables or any direct action from a user.
A key difference with other existing wireless technologies is that bluetooth enables combined usability models based on functions provided by different devices.
The Name –Bluetooth
The name is attributed to Harald Bluetooth was king of Denmark around the turn of the last millennium.
Choosing this name for the standard indicates how important companies from the Baltic region (nations including Denmark, Sweden, Norway and Finland) are to the communications industry
It provides agreement at the physical level -- Bluetooth is a radio-frequency standard.
Provides agreement at the data link level where products have to agree on
when bits are sent
how many will be sent at a time
how the parties in a conversation can be sure that the message received is the same as the message sent
The Basic Idea
Bluetooth is a standard for a small , cheap radio chip to be plugged into computers, printers, mobile phones, etc
Bluetooth chip is designed to replace cables.Information normally carried by the cable, is transmitted at a special frequency to a receiver Bluetooth chip.
These devices can form a quick ad-hoc secure “piconet” and start communication.
Connections in the “piconets” can occur even when mobile.
Bluetooth Architecture
Core Specification -Deals with the lower layers of the architecture and describes how the technology works.
Profile Specification -
Focuses on how to build interoperating devices using the core technology.
