Become a Wireless Connectivity Ninja 101
summary
Explains measurable RF tradeoffs: link budget as TX power minus receiver sensitivity and why that predicts range and coexistence; shows a multi‑protocol wireless MCU with inverted F PCB antenna and micro‑SMA, a sleep crystal to hit coin‑cell lifetimes and tiny TX bursts to reach months/years (claim: coin cell for ~15 years with right duty cycle); details BLE beacon packet layout and channels 37 38 39 versus Wi‑Fi channels 1/6/11, and stresses testing in real environments because simulations mislead.
