NB-IoT

NB-IoT is LPWAN technology for IoT with many advantages over LoRa and SigFox.

NB-IoT technology works over existing GSM network. This means all existing GSM networks with LTE can support NB-IoT if the protocol is installed by your GSM operator. One base cell can talk up to 100 000 NB-IoT nodes. One base cell can establish connection in urban area 1-10km and in rural area 10-100km One NB-IoT node can last on battery up to 10 years if less 200 bytes per day are transmitted

NB-IoT-DevKit board has these features:

  • BC-66 all world wide GSM bands coverage
  • NB-IoT 25.5 kbps up and down link
  • Ultra low power design
  • Build in Li-Po battery charger
  • Nano SIM
  • Level shifters for 5x GPIOs, I2C, SPI, UART
  • Micro UEXT connector
  • U.FL antenna connector
  • Status LEDs
  • Dimensions 40x25 mm
