D. candidate: Remo Pomposini
39. Idea: available operating frequencies for each femtocell can include all the bands allocated to the (several) mobile operators (e.g. mutual frequency exchange)7

78. Since the interference conditions prevent the femtocell from transmitting, it temporarily disables transmission and just performs spectrum sensing.12

166. network operators make arrangements one with each other to allow the reciprocal exchange of operating frequency channels
167. the simultaneous mutual interchange of spectrum bands among network operators is not currently permitted
168. Policy programmefor the use of the European Union’s radio spectrum foresees an efficient and flexible spectrum management as well as the promotion of collective use of spectrum.
