NB-IoT is low power wide area networking technology which uses existing GSM LTE technology and has many advantages versa LoRa:
- GSM network quality of service
- single GSM cell can talk to up to 100 000 devices
- high communication speed 25.5 kbps up and downlink
- secure communication using LTE encryption
- better range than LoRa both in urban and rural area (* depend on cell operating frequency – best range is om 850Mhz)
NB-IoT is already deployed in many applications:
- Remote metering of electricity, water and gas;
- Environmental monitoring;
- City waste management, parking management, Lighting management;
- Storage monitoring, logistics;
- Healthcare patient monitoring;
- Agroculture monitoring and management, remote irrigationi;
- Industrial machinery monitoring and control.
The only disadvantage is the need of SIM card from operator, but in Europe there are many options for low cost SIM cards, to not make advertisement we will not quote but prices start from EUR 1 per year.
We add 4 new modules in stock:
- NB-IoT-BC66 bare PCB module you can integrate in your PCB
- NB-IoT-BC66-ANT same as above but including GSM antenna
- NB-IoT-BC66H PCB module with soldered connectors for DIP insertion
- NB-IoT-BC66H-ANT same as above but including GSM antenna

Does anyone know of cheap network providers for these? There are some prepaid GSM re-sellers in the US like H20 Wireless that charge ~$10 USD for a 90-day plan. Some of the CDMA re-sellers like Page Plus extend that to 120-days. This is too expensive for a device that only sends a few kilobytes of data per day.
