Digital Enhanced Cordless Telecommunications (Digital European Cordless Telecommunications), usually known by the acronym DECT, is a standard primarily used for creating cordless telephone systems. It originated in Europe, where it is the universal standard, replacing earlier cordless phone standards, such as 900 MHz CT1 and CT2.
Beyond Europe, it has been adopted by Australia, and most countries in Asia and South America. North American adoption was delayed by United States radio frequency regulations. This forced development of a variation of DECT, called DECT 6.0, using a slightly different frequency range. The technology is nearly identical, but the frequency difference makes the technology incompatible with systems in other areas, even from the same manufacturer. DECT has almost universally replaced other standards in most countries where it is used, with the exception of North America.
DECT is used primarily in home and small office systems, but is also available in many private branch exchange (PBX) systems for medium and large businesses. DECT can also be used for purposes other than cordless phones. Voice applications, such as baby monitors, are becoming common. Data applications also exist, but have been eclipsed by Wi-Fi. 3G and 4G cellular also competes with both DECT and Wi-Fi for both voice and data. DECT is also used in special applications, such as remote controls for industrial applications.
Everything I've ever done
And everything I have
Amounts to nothing
Keeps on crushing you within
Sometimes you want to be alone
It won't find the time to understand
And concentrate on everything you see
If you think about it hard you'll know
