It's something so many of us use on a daily basis, not only in the car but also in the home and office - but how does Bluetooth technology actually?
Firstly, let's start with the name 'Bluetooth' - where has that been derived from? Well interestingly it is actually used in tribute to a Dane King from the late 900s. Harald Bluetooth united Denmark and part of Norway while also introducing Christianity to the country. While the Scandinavian countries are not as prominent in mobile phone development as they were 10 years ago, they have had a lasting effect on the industry.
Bluetooth is essentially a networking tool that transmits data via low-power radio waves which means that it is wireless, automatic and inexpensive. It is extremely efficient, Bluetooth has little effect on the battery of the device which is important due to the nature of its usage.
It operates on both a physical and protocol level. The physical side is that both devices must be Bluetooth enabled while the protocol level ensures that both devices agree to the connection and sharing of data.
The power of Bluetooth is that it cleverly avoids interfering with other systems such as Baby Monitors and Car Garage Doors by sending out very weak signals. For example, your mobile phone transmits a signal of 3 watts, 3,000 times stronger than the signal of Bluetooth. The low power mentioned previously restricts the range at which it can operate, devices must be within 10 metres of each other to connect. We can make use of this fact with Car Kits by only activating the connection when we are sitting in the car itself.
