The Chair of Hydrogea at the Polytechnic University of Cartagena (UPCT) has led to the development of a new technology that is characterized by low consumption and long range, in addition to working in the free frequency band ISM, which makes them ideal for distance reading of water consumption meters.
The new doctor for the Polytechnic of Cartagena Jesús Rubio Aparicio, a three-year fellow of the Hydrogea-UPCT Chair, has created during his thesis in the PhD program in Industrial Technologies three data transmission devices of smart meters that solve problems of coverage by combining several technologies in a mixed architecture.
"This thesis is an example of accelerated transfer of newly created technologies from the University to the Company," said Juan Suardiaz, who has directed the thesis with Fernando Cerdán, co-director of the Hydrogea chair.
The researchers developed a device that sends data through the wireless networks of the French operator Sigfox, another meter designed to use LoRa technology, characterized by the low consumption of its transmissions, its long range and the efficiency of its frequencies to cross walls, and a third device that links both coverages.
“Inside the building, LoRa is used and Sigfox outwards, to combine the best of both networks,” says Jesús Rubio.
During the thesis, the PhD student studied Sigfox's coverage in Cartagena and deployed his own LoRa network in Cartagena with a small antenna installed in the UPCT ELDI building with a four-kilometer radius of action.
The research has included a pilot project with meters in real residences in Cartagena and in the Sierra de la Pila to verify technology in urban and rural environments, as one of the objectives of this technology is to avoid the movement of operators to areas without coverage .
"We have improved the temporal resolution of the meters, reducing the frequency of data transmission from 15 to 10 minutes," adds Suardiaz.
The developments have been carried out within the scope of the TELIoT project 'Optimization of Hydraulic Supply Infrastructures with Smart Meter-Based Telecommunications Reading.
