APM-40 Emergency phone

详情

During a disaster, all electricity may be down and also telecommunications, including dedicated public safety networks (TETRA- or LTE-based). You might have some radio P2P connections, but it would be very difficult to build a network—a network that quickly and reliably connects the spots handling a disaster crisis: disaster task forces, Red Cross units, hospitals, logistics centers, fire departments, weather stations, and so on.

APM**0 is a fast and reliable solution for establishing a comprehensive telephone network quickly and simply. All you need is a pair of copper/steel wires and several APM**0 telephone terminals. Each APM**0 terminal represents a simple building block of the network and is strung along wires over seven kilometers long. APM is a fully decentralized system. Each APM**0 telephone terminal has embedded PBX and MUX functionality, which means you can gradually build a network of two to forty telephones without any need for a centralized unit.

The network makes it possible to carry on seven duplex voice conversations at the same time over one pair of copper/steel wire. It also allows conference calls and many PBX functionalities. APM**0 is powered by standard AA batteries (available everywhere) or local power sources (solar panels or batteries), which ensures total independence from the electricity network. Furthermore, it is possible to make connections (via a special APM**0/I interface unit) to another APM network, to a PSTN network, and to radio stations.

All of these features make APM a comprehensive, easy-to-install, and easy-to-use means for establishing a voice communication network under exceptional circumstances. Quickly established and efficient communication between disaster relief forces enables them to fulfill their responsibilities to alleviate the suffering and damage caused by disasters such as floods, earthquakes, and hurricanes.

The APM**0 system also has many applications in other fields: refugee camps, large building sites, tunnels, mines, caves, sports, and other major events.
