How to choose an IoT radio access network
summary
Compares real radio hops and deployments — satellite (Iridium) for polar remote sensors, GSM/LTE for ubiquitous backhaul, Wi‑Fi/Bluetooth for home, and LPWANs (LoRa, Sigfox) for low‑power long‑range — and shows tradeoffs: energy per bit, frequency choice (868/433 MHz versus 2.4 GHz), bidirectional needs, and operator vs private networks. Uses shelf‑edge labels, cow‑stomach pH tags and street‑light controllers as examples and stresses provisioning choices: per-device keys, manufacturing key injection, and when firmware upgrade capability is mandatory.
