Bluetooth Technology

Named after King Harald Bluetooth _ Viking King in Denmark, 910-940 AD Demark 910-940 AD First developed in 1994 by Ericsson Communication Computer implementations have grown exponentially Cable connecting devices have increased in complexity and length.

Aim of Bluetooth

Optimizes the usage model of all mobile computing and communications devices, and provides:
Global usage Voice and data handling Withstand interference from other sources Low power consumption Competitively low cost of units Very small in size and Ergonomic design

Frequency Hopping

Alternate Technology 1

IEEE 802.11 a , b , g (Wifi):
Data and Voice : BT designed-for-purpose audio channel capability. Chipsets and Cost : BT cheaper to produce with only one or two chips to implement. Security: Wifi suffers from Eavesdropping and False Authentication. BT Pairing said to be safer. WLANs are essentially ordinary LAN-protocols (TCP/IP) modulated on carrier waves. Bluetooth is more complex than that.

Alternate Technology 2

Infrared (IrDA):
IrDA is not omnidirectional, BT is. IrDA must have a free line of sight IrDA is point-to-point, only 2 units at a time can communicate
RF-enabled identification:
RFID only good for 1 or 2 metres Simultaneous connection to multiple units is limited

The Microcontroller

A microcontroller is a microprocessor (CPU) + + memory + I/O devices all on one chip. Microprocessors are programmable just like a computer Communicate with or control other devices such as computers using common protocols Cheap, Powerful and accessible IDEs WARP 13 is a device designed to program PIC family of microcontrollers Provides high level of utility functions, programming speed, reliability and ease of use.

Introduction to Thesis

Using BT Technology to monitor and track multiple personnel or objects
First test system launched in October 2003 in The Aalborg Zoo Denmark
Building on David Chews Thesis - BT and GPS in Automotive Applications
Monitor vehicle parameters using BT devices Data collected by GPS receiver and displayed on handheld via a microcontroller

Aim and Objectives

Investigate in further detail BT Wireless capability Build on and further develop David Chews project to monitor multiple moving objects Develop BT Module for monitoring Incorporate a BT Access Point instead of GPS receiver
Additional if Time Permits
Add notification function to BT module Increase range of BT Module by modifying antenna

Deliverables

Prototype to be develop consisting:
Several BT Modules for tracking in the range of 10-15 metres. Interfacing with BT Access point via Microcontroller Low level programming of BT modules.
