What is Bluetooth Technology?

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

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

Bluetooth technology lets your laptop send a print request to a printer in your next room. Bluetooth is a standard for wireless communication between devices in a relatively small area and, 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 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 devices 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, headsets, and 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 various devices, including cell phones, computers, car stereos, and headsets. It can be used to access data between these devices, whether that data is actual files or audio. Bluetooth 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 for a king in the tenth 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, allows for hands-free talking in the car or on the go, and uses no wires. This 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. However, be careful when trying this, as some wireless carriers charge extra for that connection.

Bluetooth also has its shortfall. One sits in a concise range. It depends on the connected devices, 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 many glitches, so don’t be surprised if you have trouble connecting a device or keeping it connected from time to time.

In addition to Bluetooth wireless phone models, probably the most prevalent type of devices on the market, you can now find its headphones and speakers. Other Bluetooth wireless audio and video products are expected to 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 cables 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 to implement.

The need for a standardized communication convention prompted the development of Bluetooth technology. Rather than needing each manufacturer to establish their standards and 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 benefits the end-user significantly.

Some of the other advantages of Bluetooth are fast data transfer, communication with other devices that are not in a direct line of sight (as required by the infrared protocol), inexpensive circuitry and components, and 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, such as digital cameras, mobile phones, and handheld PCs, can form a network. You can send emails to your mobile phone from your laptop without any physical connection between your computer and your mobile phone.

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.
  • Bluetooth offers a speed of 1-2 Mbps.
  • Bluetooth chipsets are less expensive, though more costly than IrDA.

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 end-user work. 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 on a circuit board of 0.9 cm square, and a much smaller single-chip version is in development and will soon be in use. The cost of the Bluetooth device is expected to fall rapidly. Bluetooth chips have to be equipped with many devices. In Bluetooth technology, small and inexpensive transceivers have been placed in digital devices. The radio waves operate at the 2.45 GHz band on Bluetooth devices. Bluetooth supports data speeds up to 721 Kbps and three voice channels. The Bluetooth chip can be built into the devices or used as an adapter. Itt can be used on a computer with a USB port. Each Bluetooth device has a 48-bit address according to 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, which guarantees security at the bit level and authentication 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 each other’s range.

Benefits of Bluetooth technology

Bluetooth technology is a convenient choice of communication in a wire-free, short-range environment. Bluetooth is a globally available standard for connecting devices to mobile phones, digital cameras, laptops, mp3 players, cars, stereo headsets, etc. Bluetooth enables devices not to need to install any drivers.
