Low-Power Sub-GHz Antennas: The Core of Long-Range IoT Terminal Deployment

Sub-GHz band antennas gradually become mainstream for long-distance IoT device networking thanks to superior signal diffraction capability compared with conventional 2.4GHz antennas. Remote countryside smart water meters install these low-power antennas to transmit consumption data to municipal management platforms across several kilometers without intermediate signal repeaters.Cold-chain logistics temperature tags mounted on transport containers leverage miniature sub-GHz chip antennas, continuously uploading cargo temperature data during cross-city long haul. Mountain forest fire early-warning sensor nodes also depend on such antennas to realize reliable wireless data transfer in sparsely-signal woodland terrain.
