Nordic Semiconductor’s nRF9160
RAM-1 is a cellular IoT- and BLE-powered remote monitoring device, allowing power grid operators to remotely monitor smart power grids and thus take immediate action in cases of failures. Institute IRNAS helped us in the development of the device. To provide RAM-1 with wireless connectivity, they have selected Nordic Semiconductor’s nRF9160 low power SiP with…

Radio measurements on the Bluetooth antenna
Nordic Semiconductor has performed tuning of the BLE antenna as well as did a quick check on GPS and mobile antenna (note the latter did not have the tuning applied yet). A set of value changes has been suggested as shown below. No geometry changes are required. Performance improvement with tuning Before: Bluetooth: around -73,…

Bluetooth low-energy interface (BLE)
In addition to NB-IoT connectivity we implemented BLE as well. Each user can connect directly to the RAM-1 device via the Bluetooth low-energy (BLE) wireless communication from a smartphone. When in range of the device, press scan and select the RAM device from the list. Upon successful connection RAM-1 replies with the latest information and…
