LoRaWAN Wide Area

LoRaWAN is a low-power, wide-area network protocol for IoT devices. LoRa (Long Range) is the physical layer; LoRaWAN is the MAC protocol on top. Devices communicate with gateways via LoRa radio. Gateways forward to a network server. Users retrieve data via HTTP API or MQTT. LoRaWAN covers entire cities with public gateways (The Things Network). Devices run for years on AA batteries. Data rates are low (300 bits/sec) but latency is acceptable (seconds). Perfect for environmental monitoring, smart metering, and industrial IoT. IoT is expanding rapidly. Cellular (LTE, 5G) and WiFi cover many cases but not all: deep indoors, rural areas, power-constrained devices, areas without cell service. LoRaWAN fills the gap: extremely low power, long range, and no subscription. Learning LoRaWAN positions you for smart city projects, agriculture IoT, and environmental monitoring. The skill is specialized: most engineers don't know LoRa yet. First-movers earn premium salaries.
