Windows 7: DECT 6.0 and 802.11b/g WiFi ??

I used to have a 5.8 ghz phone that runs right in the middle of the router and laptops/wireless devices but after a display breakdown, i decided to go out and buy a DECT 6.0 Uniden phone which claims to be WiFi friendly and not interrupting signals.

The problem with this new phone is that handsets #2 and 3 that are docked in other rooms, rely on the main phone to communicate. so i assume that there will be more signals that go around the apartment.

(might be hard to understand but im saying that the separate phones that are in other places in the house rely on the main Phone Station which is beside the router)

I also have a weak ZIO brand router which supports only b/g.



I was wondering if this new DECT 6.0 technology works well alongside with WiFi because the laptop signal i am getting in my room is very weak.

New Router soon, anyway lol.
