GPS and Bluetooth have become part of our daily lives, but have you ever stopped to think about what these terms really mean? And what’s the difference? 

What Does Bluetooth Mean? 

Did you know the term “Bluetooth” was named after the 9th century king of Denmark Harald Bluetooth? The name was chosen to honour the role Nordic countries have in the communications industry. 

Little did King Harald know that one day his name would be synonymous with a wireless technology found in a range of smart devices like smartphones, speakers and computer keyboards. 

Bluetooth allows your devices to communicate to others nearby without pesky wires.  Bluetooth has a typical range from up to 100 metres (and in some cases up to 400 metres) so that battery drain can be kept to a minimum, and has been popular since it first came on the scene in the 1990s.

How Does GPS Work? 

GPS, stands for Global Positioning System. This is when a group of satellites in space are connected to your smart device like a laptop, car or smartwatch. A GPS tracker needs to  read the signal of at least three satellites to be able to locate where an object is in the world. 

GPS trackers are able to provide more accurate location positioning, and the more satellites the GPS tracker is able to connect with, the faster your device can be found. However, you may have found yourself in a situation where you’re surrounded by very high buildings or a dense forest and have had a harder time connecting using just GPS. This is because a clear line of sight between your device and the satellites is being interrupted. 

Bluetooth technology, in comparison, only searches for Bluetooth-enabled devices close by and isn’t necessarily able to “track” locations but will be able to detect if a Bluetooth-enabled device is close to your current location.
