What's with the new DECT?
As I've alluded to above, the new DECT phones are often confused with being 6Ghz phones due to the "DECT 6.0' label on the boxes. The DECT phones operate in the unregulated 1.9Ghz frequency, where devices have to negotiate amongst themselves for air time. Right now, the main advantages of the 1.9Ghz range is it does not overlap with computer WiFi signals (2.4Ghz) and is far enough away from microwave signals that your 20 year old leaky microwave won't shut it down. DECT phones will have a better 'real world' range because of this, and won't jam up your home Wireless B/G/N router. The security measures on DECT are solid, but as I've said before, if you've got the equipment to crack any digital signal, you're probably NASA.

In short, DECT is the no-brainer choice for most people. The phones are feature-rich and the play well with others
