The demonstrated data link ensures that it cannot be detected beyond a designed range from the transmitter, while still providing reliable communication. A demonstration chipset of this sub-thermal concept was implemented in a 28 nm CMOS technology and when combined with an InP receiver was shown to decode signals up to 30 dB below the thermal noise floor by spreading a 9600 bps signal over 1 GHz of RF bandwidth from 93 to 94 GHz using a 64 bit spreading code. The transmitter for this chipset consumed 62 mW while the receiver consumed 281 mw."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Sub-thermal spread spectrum data-link","description":"We have demonstrated that the bandwidth millimeter wavelengths offer can be leveraged to deeply spread a low-data rate signal below the thermal floor of the environment (sub-thermal) by lowered transm","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11483027","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
