DECT 6.0 for the USA Marketplace

DECT 6.0 technology (versus DECT) was developed for the USA market and meets FCC regulatory requirements. Please read the DECT 6.0 Wikiedia Link above for clarifications of how this technology has evolved and how it relates to usage in other countries.


This resource page applys to DECT 6.0 for the USA. Validity to pure DECT technology for other countries is open to experimentation by our foreign amatuer friends. Look at my CS520 Part Numbers Document for more information about pure DECT for non-USA applications.
