Within Europe, the main interest in this allocation is for measurements over oceans and so the parallel proposals for EESS and MS allocations may not conflict Canadian studies show that given certain technical constraints, sharing between indoor/outdoor RLANs with EESS is feasible. Without the EIRP mask on the outdoor RLANs, EESS service will receive significant interference from RLANs
