| DeviceRadio | IoT could allow drones to deliver defibrillators directly to critical heart patients - 15 minutes faster than an ambulance. IoT could increase the crop yield for farmers in developing countries, while reducing water consumption and need for artificial fertilizers. Today there are countless hardware solutions for IoT, almost one thousand commercialIoT platforms and a multitude of connectivity options ranging from cellular to LoRa and Bluetooth. The lack of common infrastructure to bring everything together creates complexity and a huge knowledge gap. DeviceRadio is building this infrastructure. Our mission is to make it possible for millions of existing developers to be part of building a better future powered by IoT. | $279.2K | Angel | Feb 12, 2018 | http://www.deviceradio.com/ |
