Weatherproof Phone FernTel-GSM

The FernTel-GSM has been designed for use wherever wired telephone networks are either unavailable or the installation of such networks is too complicated or expensive. When connected to a solar panel (optional) it can even be fully operated without a power supply network. In case of an alarm it is still possible to use it to report an emergency. This possibility is guaranteed by virtue of the fact that two SIM cards from two different providers can be operated in the telephone simultaneously.


Design
The telephone is constructed in a housing made of polycarbonate with a protection degree of IP65 and is usable as a wall or desk mounting telephone. It incorporates a rechargeable lithium ion battery with a capacity of approx. 5 Ah, which, when fully charged, translates to a standby time of approx. 30 days or a speaking time of 21 hours. It features a quad-band GSM with the frequency bands GSM 850, GSM 900, GSM 1800, and GSM 1900.
