IOE Technologies Limited


Beside HF and UHF RFID tags and readers, IOE is developing UWB based chipless RFID system.  It will open a lot of cost-effective opportunities for retail, IoT and healthcare industries.


We supply Ultra-Wide Band (UWB) and mmWave radars for healthcare and indoor location service.  The main applications are contactless vital signs sensing, blood pressure & arterial stiffness measurement, and high-precision range measurement.


The coverage of a LoRaWAN network in a city is greatly hampered by the harsh propagation environment. Sensors are sometimes placed under the ground or in places with strong electromagnetic attenuation. IOE provides range extension to LoRa mesh networking with Repeater Node.  The Repeater Node runs OTAA protocol between LoRaWAN gateways and is compatible standard sensor nodes.
