ComputerTV Host Bauer shows of some of the many ways bluetooth can be used in your every day live. Devices in this showcase include a wireless mouse, a headset, a audio transmitter and a bluetooth adapter. All of these items connect through the bluetooth protocol so you never have to worry about wires again.
Below, you’ll find a list of the most used terms in Bluetooth technology. They can serve as a look up, or to help you learn more about Bluetooth terms in general.
2 in 1 handset
The situation where a subscriber’s handset is acting as a remote handset to a base unit that provides a network connection.
3G
Third generation, referring to the next generation of digital phone technology.
802.11 WLAN
A wireless LAN specification defined by the IEEE.
Access code
Each base band packet will start with an access code, which can be one of 3 types – CAC, DAC, and IAC.
ACK
Acknowledge.
ACL
Asynchronous Connectionless Link. This is one of the two types of data links that are defined for Bluetooth.
ACO
Authenticated Ciphering Offset.
Active mode
During the active mode, the unit will actively participate on the channel. The master will schedule the transmission based on traffic demands from the different slaves.
AP
Access point.
Authentication
The process of verifying who is at the opposite end of the link.
Authentication device
A device whose identity has been verified during the lifetime of the current link based on the authentication procedure.
Baseband
This describes the specification of the digital signal processing aspect of the hardware – the controller – which carries out the baseband protocols.
BB
Abbreviation of baseband.
BD
Bluetooth device.
BER
Bit Error Rate.
The above is more of an intro to the terms that are used with Bluetooth. Bluetooth currently has hundreds of devices, making it the best wireless solution in the world. With more coming out every day, you can bet that Bluetooth will be around for many years to come.
If you are new to Bluetooth, the terms used can be very helpful. There are hundreds of glossary terms that apply to Bluetooth, many of which describe shortcuts to common terms. You can learn a lot by reading over the meanings, especially if you have never used Bluetooth technology before.
Those of you who have experience with Bluetooth, can look over the glossary of terms to brush up on your knowledge or just check out what an unfamiliar term actually means. Nothing is complicated with the meanings, although they make take some getting used to.
Once you have been around Bluetooth for a while, you’ll find yourself right at home with the terms and meanings to the technology. All you need to do is play around with it, and read books or manuals whenever you get the chance. Before you know it, you’ll be a professional in the vast world of Bluetooth wireless.
Bluetooth has a lot to offer with an increasingly difficult market place. Bluetooth helps to bring with it the promise of freedom from the cables and simplicity in networking that has yet to be matched by LAN (Local Area Network).
In the key marketplace, of wireless and handheld devices, the closest competitor to Bluetooth is infrared. Infrared holds many key features, although the line of sight it provides doesn’t go through walls or through obstacles like that of the Bluetooth technology.
Unlike infrared, Bluetooth isn’t a line of sight and it provides ranges of up to 100 meters. Bluetooth is also low power and low processing with an overhead protocol. What this means, is that it’s ideal for integration into small battery powered devices. To put it short, the applications with Bluetooth are virtually endless.
Disadvantages
Bluetooth has several positive features and one would be extremely hard pressed to find downsides when given the current competition. The only real downsides are the data rate and security. Infrared can have data rates of up to 4 MBps, which provides very fast rates for data transfer, while Bluetooth only offers 1 MBps.
For this very reason, infrared has yet to be dispensed with completely and is considered by many to be the complimentary technology to that of Bluetooth. Infrared has inherent security due to its line of sight.
The greater range and radio frequency (RF) of Bluetooth make it much more open to interception and attack. For this reason, security is a very key aspect to the Bluetooth specification.
Although there are very few disadvantages, Bluetooth still remains the best for short range wireless technology. Those who have tried it love it, and they know for a fact that Bluetooth will be around for years to come.
Bluetooth is a specification for the use of low power radio communications to wireless phones, computers and other network wireless devices over short distances. The name Bluetooth is actually borrowed from Harald Bluetooth, a Denmark king more than 1,000 years ago.
The technology of Bluetooth was primarily designed to support simple wireless networking of devices and peripherals, which includes cell phones, PDAs and wireless headsets. The wireless signals that are transmitted by Bluetooth cover short distances of up to 30 feet, generally communicating less than 1 MPps (Mega Byte per second).
The networks of Bluetooth feature dynamic topology called PAN or a piconet. The piconets contain a minumum of two and a maximum of eight peer devices. The devices will communicate using protocols that are part of the specification.
Even though the Bluetooth standard will utilize the same 2.4 GHz range as 802.11b and 802.11g, the technology isn’t suitable for a Wi-Fi replacement. When compared to Wi-Fi, Bluetooth is much slower, limited in range and actually supports less devices.
For short range devices, Bluetooth is rapidly becoming the best. The technology is more popular with cell phones, as Bluetooth headsets are the way to go these days. To use Bluetooth, your cell phone will need to have it enabled, or an infared device somewhere on the phone.
Upcoming devices are utilizing Bluetooth as well, such as PS3 and the Nintendo Revolution. The wireless controllers will be Bluetooth enabled, which will give players the cutting edge.
If you own a cell phone or other wireless device, you should look into Bluetooth. The technology is nothing short of spectacular, making it something that will be around for years and years to come. As technology gets bigger and bigger, you can expect Bluetooth to advance as well.
The profile found in Bluetooth will describe how the technology is used. Profiles can be best described as vertical slices through the protocol stack. It will define options in each protocol that are mandatory for the profile.
The profile will also define the parameter ranges for each protocol. The concept of the profile is used to decrease the risk of interoperability problems between the different products. These profiles won’t normally define any additions to the Bluetooth specification, which is why you can add new profiles where you need them. The Bluetooth underlying technology is the same, only the specific method that it’s used is defined.
Generally speaking, all profiles of Bluetooth are based on the GAP (Generic Access Profile).
There are 9 profiles that fall in the GAP category and they are below:
To put it another way, usage models will describe Bluetooth device applications and the associated profiles that are used. The usage model focuses mainly on three categories – voice/data access points, peripheral interconnects and PAN (Personal Area Networking).
The voice and data access points involve connecting computing devices to communicating devices through a wireless link. This way, data can be transferred in a wireless manor, without the need of cables or other types of connectivity.
PAN is another very important usage model with strong appeal to business customers. Bluetooth networks are easy to set up in virtually any type of environment. An example would be meeting others at a trade show.
Instead of having contact information beamed via infrared, business cards can quickly and easily be transferred via Bluetooth wireless. The fact is that many documents can be exchanged this very same way – making the uses and possibilities virtually endless.
The Bluetooth profile is very important to the specification, as it enables you to do so much more. You can use peripherals and devices with the profiles and virtually anything else that you decide.
As Bluetooth expands and gets bigger and better, you can count on the profiles to expand and get even more functions. If you have experience with Bluetooth profiles, you should know exactly what they are and what you can do with them. If not, all you need is a Bluetooth device – and a vivid imagination.
