It said the FCC should require ending or reducing ESIM emissions to prevent harmful interference. Kymeta said existing licensees holding blanket authority for ESIMs to communicate with GSO satellite systems should be allowed to file streamlined modification applications to add blanket authority to communicate with non-geostationary satellite systems in the relevant Ku- or Ka-band.
