Kingtone 20W Tetra800MHz ʻElua ala Radio UHF Band kohoHōʻailona hōʻailonaHoʻolālā ʻia ka ʻōnaehana Bi-Directional Amplifier e hoʻoponopono i nā pilikia o ka hōʻailona kelepona nāwaliwali, ʻoi aku ka maikaʻi ma mua o ka hoʻohui ʻana i kahi Base Station hou (BTS).ʻO ka hana nui o ka ʻōnaehana RF Repeater ka loaʻa ʻana o ka hōʻailona haʻahaʻa haʻahaʻa mai BTS ma o ka hoʻouna ʻana i ka lekiō a laila hoʻouna i ka hōʻailona hoʻonui ʻia i nā wahi i lawa ʻole ai ka uhi pūnaewele.A hoʻonui ʻia ka hōʻailona kelepona a hoʻouna ʻia i ka BTS ma o ka ʻaoʻao ʻē aʻe.
Hiʻona nui
- Nā hiʻohiʻona nui o TETRA Repeater:
PA linearity kiʻekiʻe;Loaʻa ʻōnaehana kiʻekiʻe；
ʻenehana ALC akamai;
Duplex piha a me ka hoʻokaʻawale kiʻekiʻe mai uplink a downlink；
ʻO ka hana maʻalahi ka hana maʻalahi;
ʻenehana hoʻohui me ka hana hilinaʻi;
Ka nānā 'ana i ka 'āina a me ka mamao (koho) me ka ho'āla hewa 'akomi & kaohi mamao;
ʻO ka hoʻolālā weatherproof no ka hoʻokomo ʻana i nā wā āpau;

TETRA800Mhz repeater noi
No ka hoʻonui ʻana i ka uhi hōʻailona o ka hoʻopiha ʻana i ka wahi makapō hōʻailona kahi nāwaliwali o ka hōʻailona
ʻaʻole loaʻa.
Ma waho: nā mokulele, nā wahi mākaʻikaʻi, nā papa kolepa, nā tunnels, nā hale hana, nā ʻāpana mining, nā kauhale etc.
Loko: Hotele, Hale Hōʻikeʻike, Basements, Kūʻai
ʻO nā hale kūʻai, nā keʻena, nā pahu pahu etc.
Hoʻohana nui ʻia i kēlā ʻano hihia:
Hiki i ka mea hana hou ke loaʻa kahi wahi hoʻokomo i hiki ke loaʻa i ka hōʻailona BTS maʻemaʻe ma ka pae ikaika e like me ka Rx Level ma ka pūnaewele repeater e ʻoi aku ma mua o ‐70dBm;
A hiki ke hoʻokō i ke koi o ka hoʻokaʻawale ʻana i nā antenna e pale aku iā ʻoe iho-oscillation.
