LoRaWAN sells itself as kilometers of range from a coin cell, and the pitch is true — but only because chirp spread spectrum trades bandwidth and airtime for link budget in ways most builders never think through. This post walks the CSS modulation, the spreading-factor and airtime math, the star-of-stars architecture, duty-cycle regulations, and where LoRaWAN genuinely beats Wi-Fi and cellular versus where the marketing outruns the physics.

Matter, Thread, and Zigbee Untangled Matter, Thread, and Zigbee are not competitors — they live at different layers of the stack, and most of the confusion in smart-home discussions comes from pretending otherwise. We separate the application layer from the transport, walk the IPv6 mesh that Thread builds, explain border routers and commissioning, and look honestly at what interoperability delivers in 2026 versus what the marketing claims.
