From wikipedia
DECT 6.0
The "6.0" in DECT 6.0 does not specify a spectrum band, but is a marketing term coined by Siemens, for DECT devices manufactured for use in the U.S. and Canada. Although DECT 6.0 operates at 1.9 GHz, Siemens decided the term DECT 1.9 might have confused customers who equate larger numbers (such as the 2.4 and 5.8 in existing 2.4 GHz and 5.8 GHz cordless telephones) with later products. The DECT and DECT 6.0 technologies are essentially identical, except for operating frequency.
The term DECT 6.0 is also used in Australia [6]. |
