The device has an integrated antenna under the front cover. Please consider that when mounting the device so that you leave enough free space in front of the device.
The device is not rated for outdoor use without additional protective casings. As long as you use a plastic casing the built in antenna will be enough to get cell coverage in most areas. NB-IoT/LTE-M uses the following frequencies: 703-803 and 2520-2620 MHz.
When using the Telenor MIC platform to monitor the device you can see the cell coverage in the dashboard. For other IoT-platforms, the signal strenght is sent on each update, but requires a bit more hands actions to visualise it.
2500 MHz – 2700 MHz
791 – 960 MHz
