Multiple-Wireless-Sensor Operation on Ultralow-Power IoT Gateway Driven by Power-over-Fiber

We demonstrate ultralow-power operation of an IoT gateway with multiple-wireless sensors that can be driven by power-over-fiber. The power consumption is successfully reduced due to an intermittent algorithm on the gateway. We numerically show that the power-saving algorithm enables >10-sensor connections, allowing data acquisition from distant places in unelectrified areas.
