There are 79 frequencies each Bluetooth network can choose from, so frequencies that are already being used by other devices, such as your garage door, can easily be avoided. This means that the connection jumps between different frequencies within its range to maintain a strong, stable connection. One of the great things about Bluetooth is that it uses frequency hopping. All the other devices, speakers in different locations in your home, for example, are вЂњreceivers.вЂќ Frequency Hopping However, only one device, the вЂњmaster,вЂќ can send data. ItвЂ™s even possible to connect up to eight devices on one network. The songs you listen to, for example, are sent instantly from your Spotify app to your headphones. Once devices connect for the first time, the pairing is usually remembered and future connections will happen automatically, at least when both devices have Bluetooth activated and are near each other.ДЄlthough a Bluetooth connection is relatively weak, it is still effective. You have to approve each new connection, which makes Bluetooth relatively secure. When you connect two Bluetooth devices for the first time, this is called pairing. Because the broadcast signals are very weak, they usually have no effect on other devices operating at the same frequency. Easy, Fast, and SecureД«luetooth devices must be in close proximity to one another to be able to exchange information, usually within a distance of 10 meters (30 feet). Bluetooth operates at frequencies between 2.402 and 2.480 GHz. Bluetooth technology uses short-wavelength UHF radio waves to establish the connection, making it essentially a radio connection. It eliminates the need for a (USB) cable when you want to exchange data between two devices. How Does Bluetooth Work?Д«luetooth wirelessly connects different devices, such as your phone and your laptop. The method for wirelessly connecting cell phone headsets was named after the Viking leader, in recognition of the important role Nordic countries played in the development of cell phone technology.

In the tenth century, the Danish Viking leader Harald Denmark, also called Harald BlГҐtand (which translates to вЂњBluetoothвЂќ), was crowned the king of Denmark. Wondering how Bluetooth got its name? We can thank the Vikings for that. Virtually every newly manufactured device comes with built-in Bluetooth functionality. Today you can find almost everything with Bluetooth connectivity вЂ“ from wireless headphones to speakers to the refrigerator in your kitchen. The technology was developed in the early nineties by Jaap Haartsen, who worked for Ericsson. This is one of the main reasons why Bluetooth is so popular and is built into more and more devices every day. In other words, with Bluetooth, you can share information between, for example, your phone and your headphones without needing a cable.Д«luetooth is an open standard, meaning anyone can freely use the technology without a license. What is Bluetooth?Д«luetooth technology is a protocol for establishing a local network to exchange data wirelessly between nearby devices. Now is the time to get up to speed about all things Bluetooth: what it is, how it works, common Bluetooth attacks, and tips for maximizing Bluetooth security. Bluetooth could expose a great deal of data from your mobile phone, laptop, or computer. ItвЂ™s not only about people discovering which music you stream to your Bluetooth headphones, either. However, as with any wireless system, your data could be seen by unintended recipients.

In most cases, Bluetooth is more secure than Wi-Fi. The question is: how secure is Bluetooth? From smartphones to keyboards to cars, people connect devices invisibly and automatically without thinking twice.

Only connect to trustworthy sources and get rid of any suspicious connections when you notice them. Not only does this secure your device, but it also helps reduce battery drain. When youвЂ™re not using Bluetooth, turn it off. Put your Bluetooth in hidden mode, so it canвЂ™t be detected by nearby cybercriminals. Make sure your apps, operating system, and devices are regularly updated so the most recent bugs and vulnerabilities have been patched. There are several things you can do to keep your Bluetooth-enabled devices safe from these types of attacks. Bluebugging вЂ“ using a Bluetooth connection to gain backdoor access to your device.Bluesnarfing вЂ“ extracting information from a device through a Bluetooth connection.Bluejacking вЂ“ using one Bluetooth-enabled device to hijack another and send phishing messages.Clever cybercriminals rely on three tried-and-true strategies to covertly access devices through the Bluetooth function. No wireless technology is hack-proof, and Bluetooth is no exception.
