The amazing technology of Bluetooth presents a great
way of exchanging data between two wireless devices.
Unlike telephones, there are no wires or messy
leads to worry about. You can enjoy wireless
communications with short distances of up to thirty
feet.
Bluetooth also offers interoperability, meaning that
you can use your portable Bluetooth device to connect
with existing Bluetooth points. [...]
Because it meets the basic needs of connectivity in
close range, Bluetooth has a very bright future
ahead of it. Bluetooth is actually the result of
initiatives from nine leading communications and
computer industry giants, including 3-COM, Sony,
Lucent, IBM, Nokia, Microsoft, etc.
Since the forming of the original group, more than
1,800 manufacturers around the world have [...]
The technology of Bluetooth will take small area
networking to the next level by removing the need
for user intervention and help keep transmission
power very low to preserve battery power. Each
transmission signal to and from your cellular
phone will use just 1 mw of power, giving you
plenty of space on your battery to talk.
Bluetooth is [...]
Bluetooth is easily the best in wireless handheld
technology. When it comes to learning, Bluetooth
can get quite complicated. To help you, you’ll find
the key learning points of Bluetooth below:
1. Bluetooth is an energy efficient, low
overhead communication protocol that’s ideal for
interdevice communications.
2. Unlike infrared, Bluetooth doesn’t require
a line of sight.
3. Depending on [...]
Bluetooth was designed to allow low bandwidth wireless
connections to become easy to use so even those who
are new to wireless can use them. Version 1.1 of
Bluetooth describes a low power, short range wireless
networking technology that uses radio waves to send
data at rates up to 720 kilobits a second.
The specification for Bluetooth provides for [...]
Bluetooth devices will normally operate at 2.4 GHZ
in the license free, globally available ISM radio
band. The advantage to this band includes worldwide
availability and compatibility. A disadvantage to
this however, is that the devices must share this
band with other RF emitters. This includes
automobile security systems, other wireless devices,
and other noise sources, [...]
Constantly evolving, the technology of Bluetooth
started off as a basic wireless connection standard
but has since then been adapted and proven with many
different uses and functions.
A good example is Bluetooth for cell phones. It
enables mobile users to connect to their hands free
headset without using wires. Bluetooth technology
will also allow mobile phone users to [...]
Creating a good wireless headset for Bluetooth is
actually difficult to do. The regular wired headsets
are easy to design – with ranging styles.
Bluetooth headsets can never be as small or as light
as wired headsets, simply because it needs to include
the battery and extra functions. This extra size
will impact how the headset mounts on [...]
Bluetooth technology offers three different types
of defined ranges, based on output ranges. Class
1 devices are the most powerful, as they can have
up to 100 mW of power, with a regular antenna
giving them a range of around 130 – 330 feet.
The class 2 devices are lower power, offering up
to 2.5 mW of power. A [...]
Version 1.1 and earlier
Since the technology of Bluetooth was introduced in
1998, several specification versions have been
released. Versions 1.0 and 1.0B had too many issues
and problems for manufacturers to develop devices
for Bluetooth. The main issue was the lack of
communication among the devices.
The core specification version 1.1 is the first
successful operating version of [...]
