The Hama DECT Repeater could easily be with the Fritz! Box 7270 couple (firmware .59 and .67), thus achieving a normal DECT coverage. The Fritz! Box stands in the basement, the DECT repeater on the ground floor. This connects the repeater to the base and gives his signal on. Calls are made in this setting automatically with the DECT repeater; This then has the strength DECT signal throughout the building / garden (unless I'm in the basement, can be checked with the pilot tone of the DECT repeater) and works as well as in the attic, garden and the neighbor (a circumstance that with the miserable DECT range of the Fritz! Box [at the same place on the ground], was never achieved even only partly).
Technically: works perfectly, can be linked easily with the 7270 and is completely transparent (even a DECT handover works fine ()!). DECT range perfectly
Deduction of a star due to high cost (I think the price of 120, - EUR for this device (or this device class: Other DECT repeater costs about the same) grossly overdrawn).
