Dans divers modes de réalisation, l'invention concerne un dispositif électronique pouvant comprendre un premier processeur de communication (CP) basé sur une première technologie d'accès radio (RAT), un deuxième CP basé sur une deuxième RAT, ainsi que des antennes multiples raccordées opérationnelles au premier et au deuxième CP. Le premier CP peut communiquer avec une première station de base (BS) qui utilise la première RAT selon une première bande de fréquences, et peut identifier une première distance entre la première BS et le dispositif électronique, tout en communiquant avec la première BS. Le premier CP peut identifier une deuxième BS qui utilise la deuxième RAT selon une deuxième bande de fréquences, différente de la première bande de fréquences, au moyen du deuxième CP, tout en communiquant avec la première BS, et peut identifier une deuxième distance entre la deuxième BS et le dispositif électronique en réponse à l'identification de la deuxième BS. Le premier CP peut acquérir une première puissance maximale liée au premier CP et une deuxième puissance maximale liée au deuxième CP, selon au moins la première distance, la première bande de fréquences, la deuxième distance ou la deuxième bande de fréquences, et peut transmettre des informations relatives à la deuxième puissance maximale au deuxième CP, en réponse à l'acquisition de la deuxième puissance maximale.
