Bluetooth Introduction & History

Definition of Bluetooth
Bluetooth technology is a short-range
communications technology that is simple, secure,
and everywhere. It is intended to replace the
cables connecting devices, while maintaining high
levels of security. The key features of Bluetooth
technology are robustness, low power, and low
cost. The structure and the global acceptance of
Bluetooth technology means any Bluetooth enabled
device, almost everywhere in the world, can
connect to other Bluetooth enabled devices located
in proximity to one another.

The Bluetooth SIG
 The name “Bluetooth” and its logo are trademarked by
the privately held trade association named the Bluetooth
Special Interest Group (SIG).
 Founded in September 1998, the Bluetooth SIG is a
unification of leaders in the telecommunications,
computing, network, industrial automation, and
Automotive industries. Today, the Bluetooth SIG is
responsible for encouraging and supporting research and
development in Bluetooth technology.
 The Bluetooth SIG includes promoter member
companies Microsoft, Ericsson, IBM, Intel, Agere,
Motorola, Nokia, and Toshiba, plus thousands of
Associate and Adopter member companies
(BlueTomorrow.com's parent company, SP Commerce
LLC, is a licensed and certified Adopter member of the
Bluetooth SIG).

In 1994, Swedish company Ericsson Mobile
Communications launched the Bluetooth wireless
technology movement. The specification was
developed in 1994 by Jaap Haartsen and Sven
Mattisson, who were working for Ericsson at the
time. Ericsson wanted to investigate a radio interface
that would prove low-cost and low-power.
History

History of Bluetooth
Name
Bluetooth is named for king Harald Blatand
(1940-1981).Jim Kardach , who worked for
Intel, heard about King Harald Bluetooth. King
Harald Bluetooth united Denmark and Norway
and helped bring Christianity to Scandinavia.

Version
Version 1.X
Buletooth 1.0 was established in the early days
of the product's standardization. As a result,
many manufacturers' equipment did not work
with other products. Bluetooth 1.1 and 1.2 fixed
some of these interoperability problems.
Version 2.X
Bluetooth Version 2.0 was released in
November 2004. Version 2.0 increased the
speed of the Bluetooth protocol. It was
backwards compatible with Bluetooth 1.1. In
July 2007, Bluetooth 2.1 was released.
Version 3.0
Bluetooth Version 3.0 will increase data speed
and reduce power consumption. As of April
2009, it has not yet been released

Bluetooth Technology Over the Years
1998 - Bluetooth technology is officially introduced and the
Bluetooth SIG is formed.
1999 - Bluetooth 1.0 Specification is introduced.
2004 - Bluetooth Version 2.0 + EDR (Enhanced Data Rate)
is introduced.
2005 - Devices using Version 2.0 + EDR begin to hit the
market in late 2005.
2007 - Bluetooth Core Specification Version 2.1 + EDR is
adopted by the Bluetooth SIG.
2009 - Bluetooth Core Specification Version 3.0 + HS
(High Speed) is adopted by the Bluetooth SIG.

Communication & working of Bluetooth

How does Bluetooth work?
Bluetooth uses a radio technology which is called
frequency-hopping spread spectrum. It works by
chopping up the data that is being sent, and
transmitting sections of it on up to 79
frequencies.
Spread-spectrum is good for several reasons.
Firstly, the signals are very resistant to
narrowband interference, which means the
transmissions are more likely to reach their
destination quickly and intact.

 Frequency hopping spread spectrum
 Piconet
 Master device
 Slave device
 Scatternet
 Physical link

Bluetooth Profile
To use Bluetooth wireless technology, a
device has to be able to interpret certain
Bluetooth profiles, which are definitions of
possible applications and specify general
behaviors that Bluetooth enabled devices
use to communicate with other Bluetooth
devices. These profiles include settings to
parameterize and to control the
communication from start.

Data Rate
The data transfer rate of Bluetooth
technology varies depending on the
version.
 Version 1.2 offers up to 1Mbps.
 Version 2.0 + Enhanced Data Rate (EDR)
offers up to 3Mbps, and
 Data can be transferred at up to 24Mbps
for Version 3.0 + High Speed (HS)
enabled devices.

Range of Bluetooth
As for the operating range, this also varies
depending on the class of the Bluetooth device.
Class 1 radios, used primarily in industrial use
cases, have a range of 100 meters or 300 feet .
Class 2 radios, which are most commonly found
in mobile devices, have a range of 10 meters or
33 feet.
Class 3 radios have a range of up to 1 meter or
3 feet.

Bluetooth Chips - CSR
 BlueCore2 chip Bluetooth v1.1, 16-bit
XAP2 processor, A/D, audio options
 BlueCore3 chip Bluetooth v1.1-1.2, XAP2
processor, audio DSP option
 BlueCore4 chip Bluetooth V2.0, XAP2
processor

Security of Bluetooth

Bluetooth Security
Overview
These days, all communication technology faces the
issue of privacy and identity theft, with Bluetooth being
no exception. Almost everyone knows that email services
and networks require security. What users of Bluetooth
need to realize is that Bluetooth also requires security
measures as well. The good news for Bluetooth users is
that the security scares, like most scares, are normally
over dramatized and blown entirely out of proportion.
According to Bluetooth specialists, in order to
hack into a Bluetooth device, the hacker must:
1. Force two paired devices to break their connection.
2. Steal the packets that are used to resend the pin.
3. Decode the pin.

Fundamentals of Bluetooth
security
The "pairing process" is one of the most basic
levels of security for Bluetooth devices. Pairing,
is two or more Bluetooth devices that recognize
each other by the profiles they share - in most
cases they both must enter the same pin. The
core specifications for Bluetooth use an
encryption algorithm, which is completely and
entirely secure. Once the devices pair with each
other, they too become entirely secure. Until
they have successfully paired, the Bluetooth
devices won't communicate with each
other. Due to this pairing process and the fact
that it is short range - Bluetooth technology is
considered to be secure.

Bluetooth Security Issues
Bluetooth can operate in one of three security
models:
Mode 1 is non security.
Mode 2 provides security at the service level,
after the channel is established.
Mode 3 provides security at the link level, before
the channel is established.
Each Bluetooth device has a unique 48-bit
device address. The authentication scheme is
challenge-response, using symmetric keys, and
encryption is done with a key that can be up to
128 bits

Why Does Bluetooth Security
Matter?
Many Bluetooth users only use the
technology to connect a wireless headset
or similar device to their portable
computers, and they may wonder why
security is a big deal. Implementing
security, even for these types of device
pairings, can prevent an unauthorized
user from using the headset.

 If Bluetooth is in the ON mode, it does drain the
battery.
 if a user happens to leave his/her device in the
'discoverable' mode, a hacker can eavesdrop or
establish a connection with the 'discovered'
device without the user knowing about it.

Use of Bluetooth in now a days & its Future

Use of Bluetooth in now a days
 Medical & Health Devices
 Sports & Fitness Devices
 Communications
 Entertainment
 GPS (Global Positioning System)
 Education
 Internet access

•Bluetooth with mobile
 Bluetooth Technology and
Internet Access

Developing in Bluetooth
 The newest modules make it pretty easy
to go wireless. Most modules can be used
as serial cable replacements.
 The next simplest step is to add a
microprocessor to act as controller (PIC
etc.), using the module’s serial profile.
 You can develop for the native processor,
but you will need to buy some expensive
development tools.

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
