COMMUNICATING WITH NOISE: STANFORD STUDY
SOURCE: PNAS & WIRELESS INSTITUTE OF AUSTRALIA
================================================================
DATE: 03-NOV-2026
----------------------------------------------------------------
TECHNICAL SUMMARY:
STANFORD UNIVERSITY RESEARCHERS HAVE DEMONSTRATED A NOVEL WIRELESS
COMMUNICATION APPROACH THAT REDUCES ENERGY CONSUMPTION BY UP TO
1,000 TIMES USING THERMAL NOISE OR JOHNSON-NYQUIST NOISE (THE
FAMILIAR BACKGROUND HISS IN RADIO RECEIVERS).
HOW IT WORKS:
RATHER THAN GENERATING A CONVENTIONAL RF CARRIER, THE TRANSMITTER
ALTERNATES BETWEEN TWO CIRCUIT STATES:
- ABSORBING: ABSORBS SOME OF THE NATURAL THERMAL NOISE.
- REFLECTING: REFLECTS THAT NOISE TOWARDS THE RECEIVER.
THE RECEIVER AMPLIFIES AND ANALYZES THE RESULTING CHANGES TO
INTERPRET THEM AS DIGITAL ZEROS AND ONES.
POTENTIAL APPLICATIONS:
- LOW-POWER MEDICAL DEVICES AND ENVIRONMENTAL SENSORS.
- RADIO ASTRONOMY (MINIMIZING INTERFERENCE IN SENSITIVE RECEIVERS).
- SCIENTIFIC INSTRUMENTATION.
IMPLICATIONS FOR RADIO AMATEURS:
THERMAL NOISE, WHICH WE USUALLY TRY TO MINIMIZE VIA LOW-NOISE
AMPLIFIERS AND CAREFUL DESIGN, IS NOW EXPLORED AS A COMMUNICATION
RESOURCE, OPENING DOORS TO ULTRA-LOW-POWER EXPERIMENTATION.
