Bluetooth how is it used

Bluetooth is named after Danish king Harold Bluetooth. The Bluetooth logo is a combination of the two Norse runes for Harold Bluetooth's initials. You've probably seen a few Bluetooth devices already, or you may even own one and not realize it. In many parts of the world, the most well-known Bluetooth devices are hands-free wireless headsets for mobile phones, allowing you to talk and make calls while your phone is still in your pocket. Many wireless speakers and car stereos use Bluetooth to play music from other devices like mobile phones and tablets.

Remote controls for televisions and entertainment systems are replacing infrared sensors and wires with Bluetooth technology. Bluetooth might be integrated into almost any technology you can think of. The adaptive hopping technique improves Bluetooth technology's coexistence with static nonhopping ISM systems, such as Wi-Fi networks, when these are located in the vicinity of a piconet. The physical channel or the wireless link is subdivided into time units known as slots.

Data is transmitted between Bluetooth-enabled devices in packets that are positioned in these slots. Frequency hopping takes place between the transmission or reception of packets, so the packets that make up one transmission may be sent over different frequencies within the ISM band. The physical channel is also used as a transport for one or more logical links that support synchronous and asynchronous traffic as well as broadcast traffic.

Each type of link has a specific use. For instance, synchronous traffic is used to carry hands-free audio data, while asynchronous traffic may carry other forms of data that can withstand more variability in the timing for delivery, such as printing a file or synchronizing your calendar between your phone and computer. One of the complexities often associated with wireless technology is the process of connecting wireless devices.

Users have become accustomed to the process of connecting wired devices by plugging one end of a cable into one device and the other end into the complementary device. Bluetooth technology uses the principles of device "inquiry" and "inquiry scan. When an inquiry is received, the scanning device sends a response with the information needed for the inquiring device to determine and display the nature of the device that has recognized its signal.

Mouse: There are many Bluetooth mice that will easily connect with your PC, tablet and even smartphone using Bluetooth. Keyboard: Bluetooth keyboards are also available for wireless Bluetooth connection with your PC, tablet and smartphone.

They are a good solution for using a full physical keyboard with your smartphone. Printers: Many Wi-Fi-enabled printers also come with Bluetooth connection to wirelessly print documents when you are near the printer. Bluetooth Gamepads: Bluetooth gamepads, like Playstation controllers, use Bluetooth connection to connect with the console.

This also enables them to connect directly with other Bluetooth-enabled devices like a PC, tablet or smartphone to play supported games. Many smart home security gadgets come with Bluetooth support to control them wirelessly. For example, you can use your smartphone as a key to lock or unlock your doors no need for a key. Some alarm systems also come with Bluetooth integration. Bluetooth and cars go really well together, but apart from making hands-free calls, you can do many other things with the right device and setup.

Bluetooth might seem like an old technology, but it still has many uses that will help it stay in the market and in the quick access menu of our smartphones. Although the above-mentioned functions of bluetooth should be easy to set up, if anyone is having problems configuring it, feel free to let me know for step-by-step instructions.

Above I have only listed six of the most common uses of Bluetooth. I am sure there are many other uses as well. Bluetooth is wireless communication standard which allows electronic devices to connect and interact with each other.

It can be found in a number of gadgets, from smartphones, to loudspeakers, to laptops and more. Bluetooth doesn't rely on Wi-Fi, or mobile data or a cell network: as long as devices are Bluetooth compatible, and in close proximity to each other, they can take part in the wireless, two-way communication. Bluetooth has been through a number of major iterations since it was first introduced in and its first version 1.

The greatest difference between these versions is the speed at which they can transfer data, with the latest iteration, Bluetooth 5 , being the fastest and most efficient of these. This is a low-cost, widely applicable and easy to implement component: unless your phone is extremely old or extremely cheap, it should have Bluetooth. If you simply want to check if you have it, just search in the Settings of your smartphone for the word Bluetooth.

The key differences are:. Bluetooth, on the other hand, is said to have a range of at least feet and it transfers data faster than NFC. Alternatively, pull down your notification shade by swiping downwards from the top of your phone and you will likely see the Bluetooth icon. Tap it to enable or disable it. Switch the Bluetooth device on, and then from your smartphone's Bluetooth menu the path to which you can find above look for the name of the device you wish to connect to and tap on it.

By default, the name of the device you want to connect to should be very clear. A few moments later the devices should be paired. Some Bluetooth devices require a PIN for the connection to be made: if you don't know what this is, consult the device manual.

One of the most common uses for Bluetooth is to connect your smartphone to wireless speakers or headphones. You can also find thousands of small and powerful Bluetooth speakers to fit all needs and these can be put to great use at house parties when you may not want to leave your smartphone in one spot pumping out music along a cable.

Making use of hands-free headsets is another popular use for Bluetooth. You can connect small, in-ear devices to your smartphone so you can quickly and easily make calls on the go. This is a good idea for when you need to transfer larger file types when you're out of a Wi-Fi signal's reach. You can also find Bluetooth in cars.
