Cellular Connectivity for IoT
summary
Cellular IoT now offers NB‑IoT 20 kbps for ultra‑low power/low cost devices and LTE‑M ~300 kbps (up to 1 Mbps multi‑tone) for higher throughput, both added to 4G in 2016 to replace 2G hardware. Real hardware: u‑blox modules require AT‑style UART commands (demo sends UDP "ABC" to echo.ublox.com), Pycom boards run MicroPython but currently Pycom MicroPython has a compatibility issue with the Telia SIM, and Nordic nRF91 targets tiny integrated modules; Telia also offers private APN and a DataPoint backend.
