Fingerprint vs Smart Triangulation

Fingerprint vs Triangulation

There are currently two different methods used for indoor navigation and location:

Fingerprint Technology: This builds up a radio map in your premises by recording the Bluetooth fingerprint of the beacons surrounding you.

OnYourMap Smart Triangulation: Our method works in a similar way to GPS and satellites, but with beacons. We create a triangulation to obtain your coordinates, on top of which we use smartphone sensors and map information to increase accuracy.

Let’s have a more detailed look at the difference between the two methods.

The deployment of fingerprint technology is more tedious than our Smart Triangulation due to the high quantity and complexity of measurements and the amount of technical skill it requires to set up and maintain.

The problem with Fingerprinting is that as soon as its surroundings change the radio map changes, which disables its indoor navigation capabilities.
Smart Triangulation is able to compute positions even if the surroundings change, with only a slight decrease in accuracy.

You can achieve high levels of accuracy with both methods by adding beacons, but ultimately Fingerprinting’s long-term deployment will be less effective.

Smart Triangulation performs more efficiently than Fingerprinting in temporary infrastructures like malls or pop-up venues because it can amalgamate new structures without having to re-set up an entire indoor navigation system.

Crowds have a big impact on a radio map’s effectiveness – they significantly decrease the accuracy of Fingerprinting. Smart Triangulation, using its beacon contingency system, analyzes and records all beacons’ previous positions which keeps positioning accuracy high. Consequently, it performs better than Fingerprinting in airports, train stations and other heavily crowded areas.


Last but not least, as soon as a beacon is broken, stolen, out of battery or just stops working, the radio map will be compromised and Fingerprinting won’t work. Smart Triangulation, on the other hand, doesn’t rely on every beacon, so it can maintain high levels of accuracy at all times.

Facing one of these challenges means needing a maintenance manager re-setting up a part of the premises at a moment’s notice. This maintenance operation is far quicker and easier with Smart Triangulation, making it more suited to places with high expectations in term of service availability.


We started developing indoor navigation and location with Fingerprinting back in 2013. Initially the method showed promise thanks to the high levels of indoor accuracy it provided. However we quickly realised it just wasn’t flexible or stable enough to deal with many of the problems our first projects threw at us.

We solved these problems using Smart Triangulation technology, which we have been developing and improving for two years now. Our customers are really happy with its efficiency and ease of use and we couldn’t be more confident that it’s the best method of indoor navigation and location.
