SAE is a system specially designed for mining operations, it allows voice and visual/sound alerts to be sent in real time between the tunnel and the surface.
The high-power sound alert allows personnel inside the mine who are working in the area where the SAE node is installed to be alerted in real time, so that they can act immediately to safeguard their physical integrity.
It allows emergency communication in real time via Radio Tetra 400MHz, with the option of using Eth, Wifi, F.O, VHF, LTE.
