Nā hiʻohiʻona nui
- ʻenehana FPGA Base SDR, Hoʻomaʻamaʻa i ka hōʻole ʻana o ka band gain;
- Hoʻohana i ka nānā ʻana i ka naʻauao, maʻalahi ke ʻimi i nā hewa no ka mālama ʻana;
- ʻO ka hoʻohana haʻahaʻa haʻahaʻa, hoʻopau wela maikaʻi loa;
- Linearity kiʻekiʻe PA, kiʻekiʻe pūnaewele loaʻa;
- Ka nānā 'ana i ka 'āina a me ka mamao (koho) me ka ho'āla hewa 'akomi & kaohi mamao;
- ʻO ka nui paʻa, hiki ke maʻalahi no ka hoʻokomo a me ka neʻe ʻana;
- ʻO ka hoʻolālā weatherproof no ka hoʻokomo ʻana i nā wā āpau;
- Hiki i hoʻokahi MU ke hoʻokele iā Max 32 RU, mālama i ke kumukūʻai a me ka maʻalahi o ka hoʻokomo.
- Kākoʻo i ke apo, daisy kaulahao, star topology, hoʻomaikaʻi i ka maʻalahi o ka pūnaewele.
- ʻO ka hoʻolālā ʻana i nā mea lawe nui, ʻoi aku ka nui o 16 mau mea lawe, Hoʻohana maʻalahi i nā hiʻohiʻona noiʻi kiʻekiʻe
