With new electrical devices being produced every day, the problem of connecting things is becoming more and more complex in nature.  The system that comprises computers and other electronics makes use of varieties of wires, cables, etc.

These parts will communicate through light beams, lasers, radio signals, and infrared.  The problem however, is the devices and technology is often the connection between each component.  Therefore, most electronic systems aren’t used to their full extent due to the problems and imperfections.

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 connect with their hands free kit as well. (more…)

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. (more…)

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.

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 joined the initiative. According to reports, the Bluetooth technology is expected to be built into more than 100 million devices, with over 670 million enabled Bluetooth devices. (more…)

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 the implementation, Bluetooth can have a range of up to 100 meters. (more…)

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. (more…)

Bluetooth is a high speed, low powered wireless link technology that’s designed to connect phones or other portable equipment together with little to no work required by the user.  Unlike infrared, Bluetooth doesn’t require line of site positioning to work.

Current prototype circuits are contained on a board that is 0.9 cm square, with a much smaller circuit board being developed.   (more…)

The new Apple powerbook G4 are among the first computers to offer Bluetooth technology 2.0+EDR. The 2.0+EDR technology, which still backwards compatible with 1.0, is up to three times faster than previous versions, offering maximum data rate transfers of up to 3 MBps.  Being the first company to certify a system with 2.0+EDR, Apple continues to make great use of the Bluetooth technology.

Full support
In addition to the powerbook G4 portables, there are other Bluetooth enabled computers available from Apple, including the iBook, iMac G5, eMac, and the Power Mac G5.   (more…)

The networking standards of Bluetooth will transmit data via low power radio frequency.  Bluetooth communicates on a 2.45 GHz frequency.  This very band of frequency has been set aside by international agreement for the use of industrial and medical devices.

Many devices that you already known and use take advantage of this frequency band.  Garage door openers, baby monitors, and the next generation of mobile phones all use this frequency within the ISM band.  Ensuring that Bluetooth and the other devices don’t interfere with each other is a crucial part of the design process.
