Me yasa Motoci marasa matuki ke buƙatar FHSS?
●Juriya na juriya - FHSS yana hana rushewar sigina a cikin yanayin yaƙin lantarki (EW).
●Amintattun ƙaƙƙarfan ƙaƙƙarfan ƙaƙƙarfan ƙaƙƙarfan ƙaƙƙarfan tsalle-tsalle yana sa ya zama da wahala matuƙar tsangwama ko satar bayanai.
●Amintaccen filin yaƙi - Yana tabbatar da ci gaba da sarrafa UGVs masu cin gashin kansa ko da ƙarƙashin tsangwama na RF.
