What is Bluetooth Technology?

Bluetooth technology is a type of My Pro Blog the wireless technology that eliminates the need for the number of inconvenient cables and devices that are used to connect the computers, mobile phones, digital cameras, handheld devices and new digital appliances. Bluetooth enables the users to connect to a wide variety of telecommunication and computing devices easily, without cables.

What is Bluetooth Technology?

It makes fast ad hoc connections, electric, unconscious connections between two or more digital devices. Bluetooth provides the opportunity of using the mobile data in different applications. Bluetooth makes wireless communication between the two devices in a localized area of a room of office or home very quickly. Bluetooth technology uses radio-based links and all the connections between the devices and invisible and instantaneous.


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 it, therefore, works fine in the personal area network (pan) using radio frequency.

Bluetooth mobile wireless technology has become one of the leading technologies for wireless communication worldwide. The reason it has become so popular around the globe, in just a few short years since its introduction, is 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 with the intention of providing a secure and an inexpensive way to connect with and exchange information between other devices alike, all without the need of wires.

What is Bluetooth technology mainly used for? The Bluetooth mobile wireless technology has quickly become the standard for all wireless methods of communication. It can now be found 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 as one.

It is very simple to connect devices, and most cell phones and computer 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 extremely short range of the technology. It depends on the devices being connected, but they usually won’t work after even 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 seriously expensive.

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 some day 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 that are 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 they are produced by different manufacturers, 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 simply 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 alike 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 the Bluetooth devices like digital camera, mobile phone, and handheld PC can form a network. You can send emails to your mobile phones from your laptop without any physical connect between your laptop and your mobile phones.

How Bluetooth technology works

How Bluetooth technology works

Bluetooth is a high-speed wireless link technology that uses the radio waves. It is designed to connect the mobile phones, laptops, handheld devices and portable equipment with almost no work by the end users. Unlike infrared Bluetooth does not require 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 the 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 the 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 it can be used as an adapter. In a computer, it can be used with the 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. Bluetooth range is 10 meter, but it can be extended up to 100 meters by increasing the power.

Bluetooth devices are protected from the 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. Bluetooth guarantees security at the bit level and the authentication is controlled by the end user by using a 128-bit key. A prominent face of the Bluetooth technology is that it instantly forms a network when two or more devices come closer to the range of each other.
