Since the beginning of October of this year, further laboratory interoperability tests of Polish and abroad radio stations were carried out at the premises of RADMOR S.A in Gdynia (a associate of the WB Group) as part of the ESSOR task (European safe Software-defined Radio) Operational Capability 1 (EOC1). The attempts confirmed the full cooperation of all platforms utilized with the implemented waveform ESSOR-HDR (High Data Rate).
