More than that. 2G, 3G and VoLTE often distort the DTMF signal. Only VoIP technology, using a SIP protocol, guarantees reliable DTMF transmission, something that is essential for the identification of the lift when calling for help. At the same time, it delivers clear audio and saves on charges. Plus, l but not least, IP offers centralised management and monitoring of IP devices in the lift.
A single gateway with one SIM card offers you reliable emergency communication with the operator. And not just for one lift. With our modular 2N Lift8 solution, the gateway can serve up to 8 shafts. In addition, each shaft can have up to six communicators.
You can make similar savings with our 2N LiftGate IoT gateway. This combines the functions of several devices – an LTE router, switch, converter and backup power supply. It also provides voice and data communication for smart devices in the lift cabin, for the controller and the IP phone in the machine room via a single SIM card.
Easy, and you don’t even need a UTP cable in the lift shaft. Install a 2N® LiftGate IoT gateway in the machine room, ensuring data connection via a SIM or WAN port. With just two wires in the travelling cable, connect it to the 2N LiftGate Cabin Switch located on the roof of the cabin. Then you can even connect an IP communicator, camera, advertising panel or reader.
