Bluetooth Technology

Introduction

With the passage of time, technology has advanced to an entirely different level where automation and feasibility of technological tool consumption have grown to immense heights. One such technology is known by the name of Bluetooth which is a replacement for all the physical wires and cables used for the transmission of data and voice signals.

Among the major advantages of the Bluetooth devices, less power consumption, flexibility, mobility and no requirement of physical installation are worth noticing. In order to better understand about how the Bluetooth technology works and the physical and link layers used within the system; an in depth discussion regarding the relevant theories is required.

System Overview

Bluetooth is a technological tool which is based on the radio technology that provides a low power and low cost communications over the short range. Moreover, it is being thought of as a possible replacement for the cables currently being used to connect fixed or portable electronic devices, provide access points for voice and data, and building ad hoc networks.

The general characteristics of the Bluetooth technology include a 732 KBPS data rate, 10m~100m operating range, a Gaussian shaped BFSK modulation and a link layer encryption and authentication system for security.

Theory

Also known as IEEE 802.15.1, the Bluetooth system works through the correspondence of multiple layers working in a sequential as well as combined manner. Moreover, the technologically advanced working of the technology which allows the users to communicate and transfer data and voice easily is dependent on the working of the two most important layers of the Bluetooth technology including:

Physical Layer

The Physical layer of the Bluetooth technology is responsible for a multitude of functions including:

Transferring information pieces among nearby systems through the interface of air.

Interacting with the MAC sub layer for the reception and transmission of the radio waves to the connected ...
