Who invented Bluetooth?
Several organizations and engineers joined forces to invent Bluetooth technology in the late 1980s.
The Bluetooth wireless technology that connects devices and peripherals quickly became popular among users.
In 1998, different partners created the Bluetooth Special Interest Group (SIG), which was instrumental in strengthening and standardizing Bluetooth technology.
SIG brought together various players in the technology sector who collaborated to define and promote the Bluetooth standards.
However, some credit the invention of Bluetooth to engineer Jim Kardach, who worked at Intel Corporation at the time.
Besides, the Swedish telecommunications company Ericsson’s role was instrumental in developing Bluetooth technology.
IBM, Nokia, and Toshiba have also contributed to the development and standardization of this technology.
How does Bluetooth technology work?
Devices connected through Bluetooth promptly detect each other to communicate and exchange data over short distances without cables.
Anyone can use unlicensed Bluetooth’s 2.4 GHz frequency range for free, which has widespread this technology globally.
Devices featured with Bluetooth have built-in transmitters and receivers to communicate between them effectively.
When they are paired, one becomes the “host” or “master,” while the other becomes the “client” or “slave.”
The Bluetooth frequency hopping spread spectrum divides the available frequency band into numerous smaller channels.
Devices then rapidly switch between the hopping spread spectrum channels in a predetermined sequence to communicate.
Typical Bluetooth connections are either point-to-point when you connect two devices or point-to-multipoint when one device connects to multiple devices simultaneously.
Besides, various Bluetooth profiles define how different data types exchange between devices.
- The Standard shape’s Hands-Free Profile (HFP) connects audio calls.
- Advanced Audio Distribution Profile suits audio streaming connection.
- A Human Interface Device (HID) Profile lets you connect input devices such as keyboards and mice.
Furthermore, Bluetooth technology security features protect your data during transmission between devices.
This paragraph summarizes how Bluetooth technology works because the topic is too broad.

The ten uses of Bluetooth.
Wireless audio streaming.
Wireless audio streaming is the most popular use of Bluetooth, especially among younger people who are fond of trendy music.
Connecting your smartphone to Bluetooth headphones or a speaker lets you listen to your favorite songs from your phone.
Besides, portable Bluetooth speakers are more comfortable during picnics or on the go; they eliminate wire hassles.
Hands-free calls.
Bluetooth also makes it easier to use hands-free calls in different places; modern cars are typically equipped with this system.
This technology synchronizes with your car’s audio system and phone to conveniently make and receive calls quickly.
Bluetooth headsets and earphones also come with this feature that helps you stay focused on the road for your safety.
Wireless keyboards and mice.
Bluetooth keyboards and mice suit users looking for tidy workspaces and efficient use.
This wireless system connects seamlessly to your desktop, laptop, and tablet, eliminating cumbersome USB cables.
Fitness tracking.
You would have noticed that current fitness machines have Bluetooth technology to monitor users’ physical conditions.
Gadgets like smartwatches and fitness trackers also easily connect to smartphones via Bluetooth to provide helpful health information.
By tracking your daily steps, your tracker syncs this data with your phone’s health app to give you a complete performance overview.
IoT devices.
Many also use Bluetooth to connect Internet of Things (IoT) devices such as bright light bulbs, locks, etc.
By synchronizing with specific applications, loT helps control lighting, home temperature, etc.
Wireless printing.
Many would also have noticed that modern printers are wireless to simplify your printing in different locations.
You receive your impressions immediately by sending your documents or photos from your mobile device to a Bluetooth-enabled printer.
Control games.
Wireless controllers offer great freedom of movement during your favorite games on mobile devices, laptops, or desktops.
Watch how your children handle them while playing their favorite games on their smartphones to realize how essential control games are.
Data transfer.
Bluetooth is also useful for peer-to-peer data transfer between devices; it lets you quickly share photos, videos, and other files.
There is no longer any need to use messaging or electronic applications to share documents between your devices suitably.
Smart home automation.
You can also control your household appliances or the lighting in your home using the intelligent Bluetooth system.
Amazon Echo or Google Home app syncs with voice commands or other devices to track what’s happening in your home and help better secure your belongings.
Navigation and location services.
Lastly, there are navigation and location services that many undoubtedly know as essential in everyday life.
While improving navigation, Bluetooth beacons and indoor positioning systems help locate or locate different places.
Whether looking for shopping centers, airports, museums, etc., you can easily reach your destination thanks to the wireless tech.
