GPS coverage has become a fundamental tool for emergency services, significantly improving their intervention capabilities. Yet, when entering an underground area such as a subway station or tunnel, they lose that advantage as the GPS signal is lost. SubWAVE products extend 100% GPS coverage to underground areas such as tunnels, stations, parking, bus stations & airports, thus enabling localisation of any equipment or person with a standard GPS receiver (smartphone, TETRA radio or future Emergency Services Network handsets).


Syntony's SubWAVE emits a perfect emulation of the "real" GPS signal and enables the localisation of any equipment with a standard GPS chipset (safety forces, isolated staff, assets) by expanding the coverage to underground areas.


SubWAVE+ is designed to bring precise GPS positioning to GPS denied zones.  SubWAVE+ emits a signal similar to standard GPS, enabling all existing and future chipsets to receive GPS; and is the only solution worldwide that has this capability.
