GPRS Gateway
Made in Germany by Virtenio


The PreonGate GPRS Gateway with GPS functionality connects any PreonCube to the VIRTENIO online portal PreonLive. It uses a mobile radio connection and transmits the data of the numerous measuring points, such as those of PreonCube Logistics Advanced, to the online portal. The PreonCubes also transmit their data wirelessly via IEEE 802.15.4, so that all communication from the sensor to the cloud is wireless. IEEE 802.15.4 provides the cubes and gateways of VIRTENIO with a standardized framework format that can be used to implement simple point-to-point communication protocols up to 6LoWPAN (multi-hop network) with duty cycling. For operation, the gateway uses a powerful lithium-ion battery, which can also be used for several months without being connected to the mains. The battery can also be recharged during operation via a USB A socket. The robust housing (IP65) with pressure compensation valve allows use under demanding ambient conditions. The data can be viewed, analysed and exported via the PreonLive online portal using a web browser. Thus, they can monitor their remote measuring cubes from any PC, smartphone or tablet with Internet access and have an overview of their local environmental conditions at any time (24/7).


The PreonGate GPRS Gateway connects the local VIRTENIO radio network directly to the IP-based Internet. This means that there are no other requirements for the communication infrastructure on site apart from a GPRS mobile radio connection worldwide. There is no need for additional hardware, software nor power supply. The PreonGate GPRS gateway is prepared for future applications in the area of “Internet of Things and Services” and can be updated to support 6LoWPAN (multi-hop functionality) with duty cycling via IEEE 802.15.4 through a software update.In addition, the gateway supports IPv4 and is ready for IPv6.
