Signal Map: Communication Protocol Explorer

Long-range, low-power radio using chirp spread spectrum. Very robust at low data rates.

Ultra-narrowband LPWAN service with operator-managed network; tiny uplink messages.

Narrowband IoT over cellular networks, optimized for low power and deep indoor coverage.

Mainstream 4G cellular standard with high-speed mobile broadband.

4G as a family of systems, mostly LTE, for all-IP high-speed mobile networking.

Classic Wi-Fi band; good range, high interference (microwaves, BLE, Zigbee).

Low-power wireless standard for short bursts of data and beacons.

Low-power mesh networking standard for simple, reliable device-to-device links.

Higher-frequency Wi-Fi with more channels and throughput; slightly less range than 2.4 GHz.

Extension of Wi-Fi 6 into 6 GHz with many clean channels for very high throughput.

Very wideband pulses for precise time-of-flight ranging and localization.

Next-generation cellular with low latency, high throughput, and dense device support.
