Bluetooth is a wireless technology that was created and invented for the purpose of connecting two devices wirelessly so they can communicate with each other and exchange information.

Today Bluetooth is used for a wide variety of applications. Bluetooth is a method for data communication that uses short-range radio links to replace cables between computers and their connected units. Bluetooth is great for in-car use. An example of this is if your car stereo is Bluetooth capable you can use Bluetooth built in to smart phones so that your cell phone essentially ‘merges’ electronically with your car stereo so you can hear people you are talking to on your cell phone through your car stereo speakers allow you to drive safer, hands free. Bluetooth, in this context, is merely a safer way to make calls while driving, but there are many more reasons to wirelessly connect your phone with your car via Bluetooth.

Bluetooth Inventor

Bluetooth was invented in 1994 by Dr. Jaap Haartsen, former Ericsson employee, nominated as Inventor of the Year by European Patent Office. Bluetooth was born in an Ericsson lab in Lund, Sweden in the 1990’s

Why Bluetooth was Invented

The main purpose of Bluetooth is the doing away with the need for cables in most instances. Many, if not most, smart phones, mp3 players, tablets and laptops come equipped with Bluetooth connectivity. Bluetooth also allows devices from different industries and manufacturers to connect with each other. Bluetooth is present in nearly every phone and car sold today. Bluetooth is particularly convenient in certain situations like when transferring files from one mobile phone to another without cables. It can be turned on or off quickly by simply accessing Bluetooth settings of a particular device to turn the Bluetooth on or off or make the device ‘invisible’ to other Bluetooth electronic devices. Bluetooth can be used for other purposes like networking between computers, wireless Bluetooth headsets, wireless transfer of data and lots more.

Bluetooth Range

The effective range of Bluetooth can vary (maximum distance two Bluetooth enabled devices can be from each other) is approximately 100 meters. It is a standard for the short-range wireless interconnection of cellular phones, computers, and many other electronic devices.

Bluetooth Hacking

Initially Bluetooth had serious security flaws and risks in that the communication between electronic devices could be intercepted unknowingly by a third party. An example of this is a project called Blooover which was a cell phone spy and a way of exploiting this flaw with cell phones and use the Bluetooth technology to cell phone spy on a persons cell phone with Bluetooth. This security flaw has since been patched and taken care of.
