At the end of the installation, we advise you to connect to your  Backend Sigfox account  to verify that a [R xx%] appears next to the frame of your repeated products, verify the quality of the radio link of your REPEATER and its statistics (available 24H later). 

For your information: R70% signify that the REPEATER contribute at 70% of the frame reception on the backend, and so only 30% of the frame are sent directly from the product to the network.
