The activity of the MERLIN project (Innovative Radio Mechanisms for Indoor Location) consists of building a prototype of a distance measurement system based on Ultra Wide Band (UWB) technology, which implements as a differentiating technology sequences with unique properties that make them especially valuable for allowing numerous nodes to share space and radio spectrum efficiently and reliably. This will be combined, in the proposed scenario, with the use of GPS technology outdoors and with an indoor solution developed based on commercial chips, and therefore with limitations in terms of the number of nodes to be deployed, seeking to make an exhaustive comparison of both alternatives and trying to find the meeting point between them that will make it possible to deploy a highly accurate service demanded by the market.

The product to be developed with the project’s technology will be a distance estimation system that will calculate, for proprietary UWB nodes, their separation with an accuracy better than 5cm.

An application will also be developed that allows, combining the distance information of several nodes, to calculate the position of each node in a precise way.

The main difference with existing equipment is the ability to obtain accurate measurements, with high frequency (several per second) and reliability (without failed attempts), in scenarios with a high density of nodes. The state of the art has service degradation with more than 10 nodes, while this project is expected to be perfectly operational with up to 100 nodes, without a significant increase in production costs.
