What is a DECT phone?

[zoiks]

I see these phones advertised for cheap prices everywhere. What the heck is a DECT phone. I saw the explanation online but I can't tell whether these are different from the other regular cordless phones.

They have a wider range and will have much less interference with other devices due to the band they operate at.

They operate at the 6GHz range.

I see. So would these work fine with voip and a wireless router?

No.

Wiki:

Frequency: 1880 MHz?1900 MHz in Europe, 1920 MHz?1930 MHz in the US

And even in that range they interfere with WiFi if too close.

Saying that, I use three DECT phones, one on each floor of the house, and the WiFi is OK. You just need to play with the Channel you use.

From Wikipedia:

DECT was developed by ETSI but has since been adopted by many countries all over the world. The original DECT frequency band (1880 MHz?1900 MHz) is used in all countries in Europe. Outside Europe, it is used in most of Asia, Australia and South America. In the United States, the Federal Communications Commission in 2005 changed channelization and licensing costs in a nearby band (1920 MHz?1930 MHz, or 1.9 GHz), known as Unlicensed Personal Communications Services (UPCS), allowing DECT devices to be sold in the U.S. with only minimal changes. These channels are reserved exclusively for voice communication applications and therefore are less likely to experience interference from other wireless devices such as baby monitors and wireless networks.

and then below:

DECT 6.0
This is a marketing term, not a spectrum band reference. The term "6.0 GHz" for DECT 6.0 phones is incorrect, since it operates at 1.9 GHz. Calling it DECT 1.9 might have confused customers; the larger a number, typically, the better (or later) a product is. But 1.9 GHz cordless phones can operate over a greater distance than 2.4 GHz or 5.8 GHz phones can.

FWIW, until I read the Wikipedia entry just now, I thought DECT6 operated at 6GHz too. 🙂

It's misleading because it says DECT 6.0 like it operates in the 6.0GHz range.

So price aside, a DECT phone would be slightly better in regards to 802.11x interference than a 5.8Ghz phone or no?

Was curious about this as well.

Yes, much better. I have VOIP so my phone is sitting next to my router and the WIFI works fine. Granted the farthest I go is about 50 feet so if you need further distance you may want to move them farther apart but I don't have any issues. I got a set with 4 handsets for $50 from Radio Shack on black friday last year, very happy with them.
