FRITZ!DECT 301 Service - Knowledge Base
Using a radiator control outside the range of the FRITZ!Box
The radiator control works according to the DECT ULE (Ultra Low Energy) standard. You can use a FRITZ!DECT Repeater 100 to extend the range of DECT ULE-based devices. DECT repeaters from other manufacturers generally do not support the repeating function for DECT ULE devices.
