During the deployment of the first convergent TETRA + LTE system put into operation in the world, the next great challenge was to adapt the system designed and verified at Teltronic’s facilities to the Spanish Navy’s oceanographic research ship Hespérides.
After coordination between the company GMV, responsible for designing the secure PRS communication system for the GALILEO, and the Spanish navy, Teltronic went to the army’s installations in the city of Cartagena (Murcia), where an initial meeting was held to decide on the location where the radio communications systems should be placed, both the base stations of both technologies and the Control Nodes of the NEBULA infrastructure.
Qualified installers to carry out work on the ship equipped Hespérides with the antennas required by both TETRA and LTE systems to provide the simulated coverage, as well as they placed the communications systems in the defined compartments of the ship
Likewise, we deployed TETRA terminals for voice communications over narrowband technology and multimode terminals which allow the dual use of technologies, both for voice calls and broadband data transmission. LTE routers were also supplied to provide connectivity to the PRS data capture application, allowing broadband data to be sent to the ship from the shore.
Once the radio communications equipment was installed, rigorous test protocols were carried out to verify both the correct installation and the proper functioning of the system miles away from the Hespérides, thus leaving everything ready until its arrival to Antarctica.
After concluding the test protocol, everything was in place for Antarctica to be the next witness to the operation of the first TETRA + LTE convergent system.
