INTRODUCTION
Bluetooth wireless technology is an open specification for a low-cost, low-power, short-range radio technology for ad-hoc wireless communication of voice and data anywhere in the world.
BLUETOOTH HISTORY
What is Bluetooth
@Bluetooth is a short-range wireless communications technology.
Why this name
@It was taken from the 10th century Danish King Harald Blatand who unified Denmark and Norway.
When does it appear
@ 1994 “ Ericsson study on a wireless technology to page link mobile phones & accessories.
@ 5companies joined to form the Bluetooth Special Interest Group (SIG) in 1998.
@First specification released in July 1999.
TYPICAL BLUETOOTH SCENARIO
¢ Bluetooth will support wireless point-to-point and point-to-multipoint (broadcast) between devices in a Pico net.
¢ Point to Point Link
“ Master - slave relationship
“ Bluetooth devices can function as masters or slaves
¢ Pico net
“ It is the network formed by a Master and one or more slaves (max 7)
“ Each Pico net is defined by a different hopping channel to which users synchronize to
“ Each Pico net has max capacity (1 Mbps)
Ad-hoc Network “ the Scatter net
Inter-Pico net communication
Up to 10 Pico nets in a scatter net
Multiple Pico nets can operate within same physical space
This is an ad-hoc, peer to peer (P2P) network
BLUETOOTH COMPONENTS
A complete blue tooth system will require the following components:
A RF portion for receiving and transmitting data
A module with a base band microprocessor.
Memory.
An interface to the host device such as mobile.
RANGE
Data synchronization range is 10-100 meters.
1 Mbps for Version 1.2 and up to 3 Mbps for Version 2.0 +
Enhanced Data Rate (EDR).
Operates on ISM band at 2.4 to 2.485GHZ.
Divides this frequency into 79 channels 1 MHz apart (from
2.402 to 2.480 GHz).
BLUETOOT SECURITY
¢ Security Measures
“ Link Level Encryption & Authentication.
“ Personal Identification Numbers (PIN) for device access.
“ Long encryption keys are used (128 bit keys).
“ These keys are not transmitted over wireless. Other parameters are transmitted over wireless which in combination with certain information known to the device, can generate the keys.
“ Further encryption can be done at the application layer.
APPLICATIONS
Blue tooth will be used to replace cables to connect the devices.
Allow devices to find each other and form personal (ad hoc) networks and then share or synchronize data.
Allow devices to access the internet via other devices such as a cell phone, etc.
ADVANTAGES
Inexpensive chips
Low power consumption
Suitable for small devices such as
cordless phones, headsets, etc
FUTURE OF BLUETOOTH
Success of Bluetooth depends on how well it is integrated
into consumer products
! Consumers are more interested in applications than the technology
! Bluetooth must be successfully integrated into consumer products
! Must provide benefits for consumer
! Must not destroy current product benefits
Key Success Factors
! Interoperability
! Mass Production at Low Cost
! Ease of Use
! End User Experience
CONCLUSIONS
*A new global standard for data and voice
*Eliminate Cables
* Low Power, Low range, Low Cost network devices
*Future Improvements
~Master-Slave relationship can be adjusted dynamically for optimal resource allocation and utilization.
~Adaptive, closed loop transmit power control can be implemented to further reduce unnecessary power usage.
