I am a 9km5 SFR relay. I multiplied by 2.5 the quality of my signal (64k kb / O ---> 160 Kb / s) C not bad for my need but far far away from the desired result. But it suits my remote to control home automation. That is also, I tested with a FREE subscription (Orange roaming) with a relay to 4 km5; ---> = 6 result k0 / s Orange :-) Thanks .... I have not tried Bouygues ... but I think it would be better!
