2W TETRA UHF BDA 400mhz band koho hou

2W TETRA 400mhz band koho hou
Nā mea hoʻokani leo kani
Hoʻolālā ʻia ka ʻōnaehana Kingtone 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.

Kelepona hou
Hoʻohana ʻia kēia e hoʻonui i ka laulā o nā hōʻailona kelepona ma kahi laina kelepona.Hoʻohana pinepine ʻia lākou i nā laina ʻōpala e lawe i nā kelepona lōʻihi.I loko o kahi laina kelepona analog me nā uea ʻelua, aia i loko o kahi kaapuni amplifier i hana ʻia me nā transistors e hoʻohana ana i ka mana mai kahi kumu DC o kēia manawa e hoʻonui i ka mana o ka hōʻailona leo o kēia manawa ma ka laina.No ka mea he ʻōnaehana kamaʻilio duplex (bidirectional) ke kelepona, lawe ka paiea uea i ʻelua hōʻailona leo, hoʻokahi hele i kēlā me kēia ʻaoʻao.No laila, pono nā mea kelepona kelepona i bilateral, e hoʻonui i ka hōʻailona ma nā ʻaoʻao ʻelua me ka ʻole o ka hoʻopuka ʻana i nā manaʻo, e hoʻopiʻi nui i kā lākou hoʻolālā.ʻO nā kelepona kelepona ʻo ia ke ʻano o ka mea hana hou a ʻo ia kekahi o nā noi mua o ka amplification.ʻO ka hoʻomohala ʻana i nā kelepona kelepona ma waena o 1900 a me 1915 i hiki ke lawelawe kelepona lōʻihi.Eia nō naʻe, ʻo ka hapa nui o nā kelepona kelepona i kēia manawa he mau kaula fiber optic e hoʻohana ana i nā mea hoʻihoʻi optical (lalo).

Mea hoʻopuka kelepona
He leka uila kēia no ka hoʻonui ʻana i ke kelepona kelepona ma kahi palena.Ke hana nei ka mea hana e like me ke kahua kahua pūnaewele liʻiliʻi, me kahi antenna kuhikuhi e loaʻa ai ka hōʻailona mai ka hale kiaʻi kelepona kokoke loa, kahi amplifier, a me kahi antenna kūloko e hoʻolaha hou i ka hōʻailona i nā kelepona pili kokoke.Hoʻohana pinepine ʻia i nā hale keʻena o ke kaona.
 

Nā hiʻohiʻona nui
◇ PA linearity kiʻekiʻe;Loaʻa ʻōnaehana kiʻekiʻe
◇ ʻenehana ALC akamai
◇ Duplex piha a kaʻawale kiʻekiʻe
◇ Pipi kānana ʻoi
◇ Hana maʻalahi ka hana maʻalahi
◇ Hoʻolālā modular maʻalahi e mālama
◇ Kaohi mamao/nānā/alarm ma RF MODEM a i ʻole Ethernet
◇ Hoʻolālā chassis IP65 no ka hoʻohana ʻana i loko a me waho

Nā noi hana hou
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;
