When explaining long-range LoRa-class municipal sensor links at a conceptual RF level, which modulation association is most appropriate?
Select an answer to reveal the explanation.
Short Explanation
LoRa's party trick is chirp spread spectrum—long, swooping tones that dig signals out of noise for tiny payloads. It is not AM radio and not Wi-Fi OFDMA in disguise. When someone says LoRa reach, think CSS, not café Wi-Fi.
Full Explanation
LoRa-class physical layers are widely described using chirp spread spectrum techniques that favor link budget and range at low data rates. That conceptual association helps architects distinguish LPWAN links from Wi-Fi OFDMA or legacy AM schemes. Treating CSS as meaningless marketing ignores a core RF characteristic of many long-range IoT deployments.
