RESOLUTION 909 (WRC12) Provisions relating to stations located on board vessels which operate in fixed-satellite service networks in the uplink bands 5 925-6 425 MHz and 14-14.5 GHz The World Radiocommunication Conference (Geneva, 2012), considering that introduced provisions relating to the use of earth stations a) on board vessels (ESVs) in certain bands allocated to the fixed-satellite service (FSS); that the technology used by ESVs has advanced considerably since b) their introduction, including the use of spread-spectrum modulation and other techniques which may improve compatibility with terrestrial services; that ESV applications can provide high-bandwidth connectivity in c) where no alternative exists; that ESVs may have the potential to unacceptable interference d) to terrestrial services operating in the same bands; that earlier ITUR studies, using technical criteria appropriate at the e) time, resulted in a set of limitations on the operation of ESVs contained in Resolution 902 (WRC03), in order to protect terrestrial services operating in the same bands; that these limitations and restrictions need to be reviewed in light of f) the new technologies being deployed; that there are situations where there is no potential for unacceptable g) interference but current rules still require that an agreement be obtained from concerned administrations, recognizing that there are several other services than FSS to which the a) frequency bands 5 925-6 425 MHz and 14-14.5 GHz are allocated; that these other services need to be protected, b)
