Bluetooth actually has nothing to do with teeth. It’s a wireless technology standard for exchanging data over short distances using short-wavelength UHF radio waves.
So, what’s the story behind the name? The original standard was developed by telecom vendor Ericsson in 1994 as a wireless alternative to rs-232 data cables. It didn’t receive the name “Bluetooth” until 1997 when Jim Karthik, who developed a communication system between mobile phones and computers, proposed it while reading The Long Ships, by Frans Gunnar Bengtsson—a historical novel about Vikings and the Scandinavian King Harald Bluetooth. Legend has it that he united the Danish tribes of that period into a single unified nation, much like what the introduction of the Bluetooth standard did for communication protocols.
What does Bluetooth do?
Simply put, it facilitates communication between two to eight devices where there is one master device and up to seven slave devices. While it was only intended to replace serial cables, it can do so much more. You can wirelessly control and communicate between a mobile phone or tablet and a hands-free headset, car audio system, speaker system, or intercoms. You can network with a PC to transfer files or control printers and computer peripherals, barcode scanners or traffic control devices, and even replace infrared scanning in some cases. And that list is not exhausted by any means.
How does Bluetooth work?
There are two main components. At the physical level, it works like any other radio-frequency standard with antennas that can broadcast and receive signals in the appropriate bands. But at the protocol level, things are a little bit different. To achieve a robust enough connection for communication and use, even in environments with massive interference, Bluetooth communicates with very short transmission bursts and then quickly does micro hops around to the various frequencies within its range. It allows more than one device to transmit on the same frequency at the same time. But constant transmission of data means higher power consumption, and for years, most Bluetooth devices suffered from short battery life that pained users and made the standard not practical for many applications.
Bluetooth smart arrives
A few years ago, Bluetooth 4.0—or Bluetooth Smart—arrived on the scene. It’s basically the power-efficient version of Bluetooth that has enabled amazing stuff like devices with one to two years of battery life on a single button cell. However, one issue with Bluetooth smart accessories is that they can only be used with Bluetooth Smart-ready primary devices—smartphones, notebooks, and tablets. This is a qualification given to phones that are by definition compatible with Bluetooth Smart accessories, meaning that there is no backward compatibility between phones with older versions of Bluetooth and devices that are equipped with Bluetooth Smart.
Bluetooth Smart-ready primary devices, on the other hand, are backward compatible with accessories that run older versions of Bluetooth.
One other cool Bluetooth 4.0 fact is that range is no longer locked down, so while manufacturers can opt to optimize for more traditional 10 meter or 30-metre ranges, it’s possible for devices to work at 60 meters or beyond.
To sum it up, Bluetooth is a low-speed, interference-resistant communication protocol that allows devices to transfer data across multiple platforms at short range with excellent efficiency.
Using Bluetooth in your vehicle
The main advantage of having access to Bluetooth in your car is that you can pair your radio system with your cell phone to be able to hear the caller’s voice thru the radio speakers, see caller info on the display, and stream audio or music from the phone.
Most importantly, it lets you focus on driving without taking your eyes off the road.
There are three ways to use a Bluetooth device in your car:
- Universal Bluetooth kits which can work in almost any vehicle
- Model-specific adapters that connect to the car’s factory radio
- Installing a new radio that has Bluetooth capability
Of course, using a universal adapter will always be the easiest way to do this.
