Wireless range extension for CoSi ISM transmitters

The ISM-LoRa gateway enables the reliable transmission of wireless alarms over longer distances, thereby significantly extending the range of CoSi ISM wireless transmitters. It receives signals from energy-efficient transmitters in the 2.4 GHz ISM band and relays them via LoRa long-range radio to receiving units in neighbouring buildings. Depending on the building and landscape conditions, transmission is possible over a distance of up to approximately 2 km.

Integration is flexible: in conjunction with a LoRaWAN gateway, alarms can be forwarded directly to a CLAS server and then signalled, for example, via mobile CLAS end devices. Alternatively, stand-alone operation with a LoRa alarm receiver as the receiving unit is also possible.

The gateway features a loudspeaker and a device button. The loudspeaker can be used to confirm receipt of self-triggered alarms via a voice announcement to reassure users. The device button allows the quality of the radio connection to the receiving unit to be easily checked at any time and also communicated via a voice announcement.

Thanks to simple commissioning, integrated power failure protection and reliable wireless technology, the ISM LoRa Gateway is ideally suited for applications where alarms from any CoSi ISM wireless transmitters need to be reported over long distances.
