What is ELTRES ?

ELTRES is an LPWA (Low Power Wide Area) wireless communication standard that can be used in IoT networks, developed by combining various technologies cultivated by Sony.

Many IoT systems are configured to transmit information obtained from the various sensors to cloud servers via wireless communication, store and process data in the cloud, and finally display the results on users' smartphones and tablets. LPWA network technologies are wireless communication technologies that only transmit a small amount of data but consume low power and can be used over a wide area.
Sony has developed ELTRES to meet the needs for collecting sensor data outside of the conventional mobile phone service area, such as at sea and in mountainous areas, and to provide an inexpensive means of communication that is resistant to interference even within the mobile phone service area in urban areas.

ELTRES has three major features: long distance stable communications, reception even while moving at high-speeds, and low power consumption. It can efficiently collect information acquired by various sensors over a wide area and can be used to enable completely new use cases for IoT.

Three Features of ELTRES

  • Robust long-distance communication

    Transmission at ranges of over 100 km

  • High-speed mobility communication

    Even when moving at over 100 km/hr

  • Low power consumption

    Operates on a single coin battery
