NB-IoT-DevKit is OSHW certified Open Source Hardware with UID BG000058
NB-IoT-DevKit is IoT board with BC66 LTE GSM module which covers all world wide GSM bands.

NB-IoT (Narrowband Internet of Things) technology is a direct competitor to LoRaWAN and SigFox and has a few advantages:

  • higher speed 25.5 kbps up and down link
  • single GSM cell can connect to up to 100 000 NB-IoT nodes
  • single GSM cell can cover up to 10-100km rural and 1-10km urban distance
  • can work up to 10 years on Lithium 3V battery if less than 200 bytes are sent per day
Note: All GSM cells which work with LTE can also support NB-IoT, but this requires new protocol installation and licensee fee, so not all operators provide it by default. You have to check with your local GSM operator if he offers NB-IoT. Also SIM card must have this protocol enabled. SIM with LTE may or may not work with NB-IoT, this depends on your operator.
