 The Freedom of Bluetooth
Wouldn’t it be great to quickly connect your PC to another
PC to share music, data and calendar info, without using
any wires? Or wirelessly access phone numbers on your
PDA from your cell phone? Wouldn’t talking on a phone
while driving be easier – and dramatically safer – if you
didn’t have to be distracted holding the phone or be
tethered to a wired headset?

Wouldn’t it be cool to be able to enjoy rich stereo audio
from your MP3 player or home entertainment system
wirelessly, with complete freedom to walk from den to
kitchen without interruption? Want to get rid of the yards
of cables snaking through your office but still be able to
use your computer to access the Internet, print files, sync
data with your PDA, and print photos taken from your
digital camera minutes ago, wirelessly?

With more and more cars coming equipped with
Bluetooth technology, imagine the convenience as well
as safety of conversing with family, friends and business
associates without taking your hands off the wheel. Won’t
it be nice to be able to wirelessly navigate even the most
difficult routes in foreign cities using Bluetooth and GPS

Now you can. Bluetooth is here!

 The Freedom of Bluetooth

Bluetooth is a standard for a small, low-cost, power
efficient radio chip that can be used by computers,
printers, mobile phones, headsets, headphones, and
numerous other consumer electronics. This technology
allows multiple devices to communicate with each other,
or one device can control and manage several other

Much in the same way that King Harald Bluetooth united
Denmark and Norway, Bluetooth was designed to unite
computers, phone equipment and many other electronics
devices. Back in 1994, Ericsson Mobile Communications
began a feasibility study on an inexpensive low-power
radio solution between cell phones and phone accessories.
Four years later, Ericsson, along with Nokia, IBM, Toshiba
and Intel formed the Bluetooth Special Interest Group
(SIG). This association represented leading companies
in mobile telephony, notebook computers and a market
leader in digital signal processing technology.

Bluetooth was positioned as “easy to use” link that would
create a personal area network. Immediately, the media
and public raised unrealistically high expectations even
before the first hardware products arrived. The technology
initially delivered more failures than successes, with
numerous bugs, complexities, and incompatibilities.

By 1999 – the year Bluetooth Spec 1.0 was introduced
 The Freedom of Bluetooth
- 850 companies had joined the SIG. A year later, when
spec 1.1 was accepted, the Group boasted well over
1,000 members and a full 2000 companies had become
involved by Fall 2003 when Bluetooth Spec 1.2 was

Today, the Bluetooth SIG counts among its members
3,400 companies.

  Instant Multi-device Network
  A Bluetooth to USB Adapter such as IOGEAR’s
  GBU311 or GBU211 allows any computer to become
  a Bluetooth-enabled computer, and be able to send
  to and receive information from a wide variety of
  other Bluetooth products.

 The Freedom of Bluetooth

How does it work?

Bluetooth takes the information normally carried by a
wire and transmits it at a special frequency to another
Bluetooth device. Both the sending and receiving devices
have what is called a Bluetooth receiver chip, which
translates data into a wireless transmission and then
back to normal again, depending on if it is sending or
receiving data.

 The Freedom of Bluetooth

Bluetooth vs. WiFi
Perhaps pitting these two wireless technologies against
each other is unfair since both offer unique advantages
and complement rather than compete with each other.
WiFi offers a means to wirelessly connect one or more
computers to each other and to a router so they can access
the Internet. WiFi range can reach longer distances than
Bluetooth and transfers data faster as well.
Bluetooth is a short-range wireless medium but offers a
means to link not just computers, but PDAs, headphones,
headsets, printers and other technology with each other.

      The Freedom of Bluetooth
    You can link your computer, printer and cell phone with each
    other, so both the computer and cell phone can print without
    cables. You can sync the address book on your computer
    with your cell phone. Using your Bluetooth headset, you can
    wirelessly communicate with friends using SKYPE, Vonage
    or other Voice over IP (VOIP) phone system.

    A computer can use both Bluetooth and WiFi simultaneously.
    A wireless WiFi connection can connection the computer
    to the Internet access point, while Bluetooth adapter can
    allow the computer to print wirelessly and well as “speak’
    with other Bluetooth-enabled devices such as a headset,
    PDA, etc.

Bluetooth Specs and Classes
Since its introduction in 1994, the specifications for
Bluetooth have continuously improved.

Bluetooth 1.0 and 1.0B
The original Bluetooth specifications had numerous
problems and the various manufacturers had great dif-
ficulties in making their products interoperable. Because
of the way Bluetooth devices had to communicate with
each other, anonymity was impossiblel

Bluetooth 1.1
In version 1.1 added support for non-encrypted channels
was added

Bluetooth 1.2
This version is backwards compatible with 1.1. Major
enhancements include:
• Adaptive Frequency Hopping (AFH), which improves
   resistance to radio interference by avoiding the use
   of crowded frequencies
• Higher transmission speeds

Bluetooth 2.0
This version is backwards compatible with 1.x. The main
enhancement is the introduction of Enhanced Data Rate
(EDR) of 2.1 Mbit/s.
• 3X faster transmission speed (up to 10 times in
   certain cases).
• Lower power consumption
 The Freedom of Bluetooth
Bluetooth devices are known as Class 1, Class 2 or
Class 3.

 Connecting with Bluetooth

Can anyone connect with my Bluetooth devices?

You can easily connect with your friends’ and colleagues’
Bluetooth devices to share information, pictures, Internet
access, and a wide range of other uses. However,
Bluetooth features three types of built-in security to
prevent unwanted connections with your equipment:
Pairing, Encryption, and Pass Key Protection

             Bluetooth Built-in Security:
                       - Pairing
                    - Encryption
                     - Pass Key



This function enables Bluetooth devices to remain
permanently linked to each other. Even if a “paired”
Bluetooth device is turned off, or just out of range, it will
be visible to the Bluetooth devices it has been paired
with when it is powered on again or comes within range.
 Connecting with Bluetooth
Bluetooth features 128-bit security encryption to make
sure that no other devices can receive transmissions
that you send.

Pass Key
This is a unique, case-sensitive password that is set
by the user and is required in order to access and
communicate with the Bluetooth device. The Pass Key is
continually incorporated into the 128-bit Encryption; also
it reinforces pairing by only allowing devices to pair if the
password matches.

Bluetooth on the Road
As noted earlier, nowhere is Bluetooth more at home
as on the road. By eliminating wires, Bluetooth allows
drivers to converse telephonically without jeopardizing
safety. Voice operated Bluetooth-enabled cell phones and
Bluetooth headsets were quite literally made for each
other, and give drivers complete freedom to get to their
destination safely while staying in touch.

Car manufacturers from BMW to Chrysler to Toyota
equip their cars with Bluetooth technology as standard
equipment. With a compatible Bluetooth-enabled phone,
drivers can place and answer calls as well as browse
and select phone book contacts simply by using buttons
often found on steering wheels and keys on their radios.
 Connecting with Bluetooth
On some vehicles, it’s even possible to activate these
functions using voice commands that interface with
the vehicle itself. Just say, “Phone home,” and you’ll be
connected in moments, without having to lift a finger off
the wheel.

Getting lost while driving is becoming a thing of the past with
Bluetooth GPS systems such as IOGEAR’s GBGPS201.
This palm-sized device wirelessly communicates with
GPS satellites and Bluetooth-enabled PDAs, notebook
computer, or car-mounted PCs that are gaining in
popularity. Guidance information is transmitted from the
satellites to the GPS and wirelessly from the GPS to the
PDA/notebook/dashboard-mounted PC monitor. These
GPS systems can be carried from one vehicle to another,
including rental cars, ending frustration and optimizing
business travel.

 Bluetooth Networking
Can I use Bluetooth to create a network?

All that is needed to connect to a network is a Bluetooth
enabling device, such as IOGEAR’s Bluetooth to USB

  �������������������������        ��������

 Bluetooth Networking
As many as eight Bluetooth devices can be connected at
once! For example, you can have a couple of Bluetooth-
enabled computers, a mobile phone, a video camera, a
printer, a PDA, and a Bluetooth access point all working
together to share an Internet connection, synchronize
address books and calendars, share a printer, and
perform various other functions.

If there are more than eight Bluetooth devices in the same
area, only eight of them can be linked together via pairing
to communicate at the same time. Any other devices will
not interfere with the Bluetooth network.


 Bluetooth Networking
Will Bluetooth interfere with other wireless

Bluetooth™ operates at the 2.4 GHz range. While wireless
Ethernet 802.11 and some cordless phones do share the
2.4 GHz band range, Bluetooth is designed to operate
in a noisy-frequency environment; moreover, by using
constant frequency hopping, any possible interference
would be minimal and intermittent.


Bluetooth offers a very affordable, high-speed, secure,
simple and dependable way to communicate and share
data wirelessly. Today Bluetooth technology spans the
technology, automotive, medical, gaming, entertainment,
communications and other industries worldwide.

That’s why companies including Lexus, Texas Instruments,
Apple, Hewlett Packard, BMW, Sony Ericsson, Chrysler,
Microsoft, Motorola, Nokia, Toshiba, and hundreds of
other developers are introducing more and more new
Bluetooth-enabled products that incorporate this new
proven standard in communications.
