By Bluetooth technology, your laptop can send a print request to a printer in your next room. Bluetooth is a standard for wireless communication between the devices in a relatively small area and is, therefore, works fine in the personal area network (pan) using radiofrequency.
Bluetooth mobile wireless technology has become one of the leading technologies for wireless communication worldwide. It has become so popular worldwide in just a few short years since its introduction because it allows phones, computers, PDAs, and other electronic devices to communicate with the other enabled devices nearby easily. The range of its networking is limited to a short range of about 30 feet.
Bluetooth utilizes radio waves in the non-licensed range of 2.4 Gigahertz. This system has been designed to provide a secure and inexpensive way to connect with and exchange information between other devices alike, all without the need for wires.
What is Bluetooth technology mainly used for? Bluetooth mobile wireless technology has quickly become the standard for all wireless methods of communication. It can now be integrated into the latest and most popular models of handheld computers, laptops, PDAs, printers, and headsets, not to mention cellular phones. Manufacturers are finding more and more products to add the technology to as the demand for this enhancement increases.
What is Bluetooth Technology
Bluetooth, in its essence, is simply a wireless connection between two devices. It can connect all kinds of devices, including cell phones, computers, car stereos, and headsets. I can be used to data between these devices, whether that data is actual files or audio.
It was created in 1994 by Ericsson in the hopes that it would become the standard for connecting all kinds of devices. In fact, that is where the name came from. Bluetooth is a variant of a Danish name of a king in the ten century who brought many small kingdoms together.
It is effortless to connect devices, and most cell phones and computers come with it installed. The technology itself could be compared to the technology in your remote control at home, although that technology is typically only one way, whereas Bluetooth technology is two-way. However, the concept is the same. Your remote control is simply sending data to your television wirelessly.
Bluetooth technology also has some serious advantages. It is a free connection, it allows for hands-free talking in the car or on the go, and it uses no wires. The fact that no wires are involved makes file sharing simple.
One little-known use of Bluetooth technology is known as tethering. With tethering, you can connect your phone to your computer via Bluetooth and use your phone’s data connection to connect to the internet. This is a great option when there are no Wi-Fi hotspots around. Now that many phones have 3G connections, the internet can have a decent speed when connected. Be careful when trying this, though, as some wireless carriers charge extra for that kind of connection.
Bluetooth also has its shortfalls as well. One is the concise range of the technology. It depends on the devices being connected, but they usually won’t work after getting a few feet apart. Also, if your device, such as your computer or car stereo, does not already have it installed, adding Bluetooth technology can be costly.
Also, in my experience, connections of this type can be sporadic. The technology has not been around long enough to be refined, and it still has a lot of glitches, so don’t be surprised f you have trouble connecting a device or keeping it connected from time to time.
In addition to the Bluetooth wireless phone models, which are probably the most prevalent type of devices on the market, you can now also find its headphones and speakers. It is expected that other Bluetooth wireless audio and video products will continue to be brought to the marketplace.
With this type of advancement, it is conceivable that someday the only wires you will need to tame will be the power cords that some of these devices will need for their power supply. That would be a welcomed change from the tangles of cords and wires common in home offices and entertainment areas.
One of the best features is that all its enabled devices function on a standard protocol. This means that all transmission of data and voice signals between two of its devices, even if different manufacturers produce them, is straightforward and simple to implement.
It was the need for a standardized communication convention that prompted the development of Bluetooth technology. Rather than the need for each manufacturer to establish their standards and thereby limit the connectivity to other devices made by the same company, they can implement the Bluetooth wireless technology networking standard. This simple approach has made it a global solution used by all manufacturers and benefiting the end-user significantly.
Some of the other advantages of Bluetooth are data transfers that are fast; communication with other devices that are not in a direct line of sight (as required by the infra-red protocol); inexpensive circuitry and components; the ability to transmit both data and voice concurrently.
Any two devices that follow the Bluetooth standard can communicate with each other. Many Bluetooth devices like digital cameras, mobile phone, and handheld PC can form a network. You can send emails to your mobile phones from your laptop without any physical connection between your laptop and your mobile phones.
Features of Bluetooth technology
- Bluetooth technology uses radio waves for communication in 2.4 GHz
- It supports multipoint communication, not just point to point.
- Bluetooth works in a small area of 10-15 meters.

How Bluetooth technology works
Bluetooth is a high-speed wireless link technology that uses radio waves. It is designed to connect mobile phones, laptops, handheld devices, and portable equipment with almost no work by the end-users. Unlike infrared, Bluetooth does not require a line of sight between the connecting units. Bluetooth technology is a modified form of the current wireless LAN technology, and it’s more acceptable for its relatively small size and low cost.
The current circuits are contained on a circuit board of 0.9 cm square, and a much smaller single-chip version is in development, and soon it will be in use. The cost of the Bluetooth device is expected to fall rapidly. Bluetooth chip has to be equipped with many devices. In Bluetooth technology, small and inexpensive transceivers have been placed in digital devices. The radio waves operate at 2.45 GHz band on the Bluetooth devices. Bluetooth supports the data speed up to 721 Kbps and three voice channels. The Bluetooth chip can either be built into the devices or used as an adapter. In a computer, it can be used with a USB port. Each Bluetooth device has a 48-bit address from the IEEE 802 standards, and the Bluetooth connections can be either point to point or multipoint. The Bluetooth range is 10 meters, but it can be extended up to 100 meters by increasing the power.
Bluetooth devices are protected from external interference because they change their frequency up to 1600 times in a second. Bluetooth radio technology provides the bridge between the existing data network. The end-user controls Bluetooth guarantees security at the bit level and the authentication by using a 128-bit key. A prominent face of Bluetooth technology is that it instantly forms a network when two or more devices come closer to the range of each other.
