We're excited about
our new ezTalker Bluetooth® wireless
headsets for cordless hands-free communications. ezTalker is
compatible with all mobile phones that feature Bluetooth V1.1
technology. But what exactly is "Bluetooth"
and what makes it unique?
One of the newest technologies that has been announced for
use with various personal electronic devices (mobile phones,
PDAs, etc.) is called Bluetooth, named after a Danish King
called Harold Bluetooth who was able to unite all of Denmark.
Bluetooth is designed to provide local connections between
devices and peripherals that are close in proximity to one
another. These peripherals may include your PC for synchronization,
a mobile phone for internet access or remote headphone support,
and possibly internet access via an access point. Some call
this concept a Personal Area Network or PAN.
Bluetooth wireless technology is designed to support up to
eight (8) devices operating within a small radius of 30 feet
from each device with 2.4 GHz frequency spectrum. Bluetooth
technology operates at one megabit per second for high speed
communications. The one megabit connection is divided between
a 64k connection for synchronous voice and a 768k connection
for data so you can't get a true one megabit data connection.
Some users are concerned about security and according to
the Bluetooth consortium, the Bluetooth technology specifications
includes device authentication, user authorization, and voice
encryption features to ensure no one else is intercepting
Services provided by Bluetooth technology are defined as
a series of profiles. Profiles are described as usage scenarios
for devices including the communication speed, voice support,
etc. For example, there are profiles for voice for remote
headsets, data emulating a serial connection, and for a network
connection. So far each vendor has to define how they plan
on using Bluetooth technology and which profiles will be
supported. Each device that you wish to communicate with
needs to support a profile that is compatible with a profile
on your master device.
Currently there are two versions of Bluetooth technology:
Bluetooth 1.0 and Bluetooth 1.1. With Bluetooth 1.0, users
are required to "bind" with only one device at
a time to use them with Bluetooth. With Bluetooth 1.1, users
are allowed to communicate with up to eight (8) devices at
the same time. Of course all of these devices must be compliant
with Bluetooth 1.1 technology.
Bluetooth technology brings the promise of wireless interoperability
between different electronic communication systems; mobile
phones, PDAs, and computers. Based on our experience, it's
not just hype. Bluetooth really does work and, best of all,
it works well.
