He aha ke kahua kahua
I nā makahiki i hala iho nei, ʻike mau ʻia nā nūhou e like me kēia i kēlā me kēia manawa:
Ua kūʻē ka poʻe nona nā hale noho i ke kūkulu ʻana i nā kahua kahua a ʻoki i nā uwea optical ma kahi pilikino, a ua hana pū nā mea hana nui ʻekolu e wāwahi i nā kahua kahua āpau o ka paka.
ʻOiai no nā kamaʻāina maʻamau, i kēia lā, i ka wā i komo ai ka Pūnaewele kelepona i nā ʻano āpau o ke ola, e loaʻa iā lākou ka manaʻo maʻamau: hoʻokuʻu ʻia nā hōʻailona kelepona paʻa e nā kahua kahua.No laila pehea ke ʻano o ke kahua kahua?
Hoʻokumu ʻia kahi ʻōnaehana kahua kahua piha me BBU, RRU a me ka ʻōnaehana feeder antenna (antenna).
Ma waena o lākou, ʻo ka BBU (Base band Unite, baseband processing unit) ʻo ia ka mea ʻoi loa o nā mea hana ma ke kahua kahua.Hoʻokomo ʻia i loko o kahi lumi kamepiula huna a ʻaʻole hiki ke ʻike ʻia e nā kamaʻāina maʻamau.ʻO ka BBU ke kuleana no ka hana ʻana i ka hōʻailona a me ka ʻikepili o ka pūnaewele kumu a me nā mea hoʻohana.Hoʻokomo ʻia nā protocols paʻakikī a me nā algorithm i nā kamaʻilio kelepona paʻa i ka BBU.Hiki ke ʻōlelo ʻia ʻo ka base station ka BBU.
Mai ka hiʻohiʻona, ua like loa ka BBU me ka pahu nui o kahi kamepiula desktop, akā ʻo ka mea ʻoiaʻiʻo, ua like ka BBU me kahi kikowaena hoʻolaʻa (ma mua o ka hoʻokipa kamepiula nui).Hoʻomaopopo ʻia kāna mau hana nui e nā ʻano ʻelua.Hoʻomaopopo ʻia nā papa kī e ka papa mana nui a me ka papa baseband.
ʻO ke kiʻi ma luna he kiʻi BBU.Hiki ke ʻike maopopo ʻia aia he 8 mau pahu huki like i loko o ke kiʻi BBU, a hiki ke hoʻokomo ʻia ka papa mana nui a me ka papa baseband i loko o kēia mau kau, a me kahi kiʻi BBU Pono e hoʻokomo ʻia kekahi mau papa mana nui a me nā papa baseband. e pili ana i ka pono o ke kahua kahua e wehe ʻia.ʻOi aku ka nui o nā papa i hoʻokomo ʻia, ʻoi aku ka nui o ka mana o ka base station, a ʻoi aku ka nui o nā mea hoʻohana i hiki ke lawelawe ʻia i ka manawa like.
ʻO ka papa mana nui ke kuleana no ka hoʻoponopono ʻana i ka hōʻailona (RRC signaling) mai ka pūnaewele kumu a me ke kelepona paʻa o ka mea hoʻohana, nona ke kuleana no ka hoʻopili ʻana a me ka launa pū me ka pūnaewele kumu, a nona ke kuleana no ka loaʻa ʻana o ka ʻike hoʻonohonoho GPS a me ka ʻike kūlana.
Ua hoʻokomo mua ʻia ka RRU (Remote Radio Unit) ma ke kiʻi BBU.Ua kapa ʻia ʻo RFU (Radio Frequency Unit).Hoʻohana ʻia ia e hoʻololi i ka hōʻailona baseband i hoʻouna ʻia mai ka papa baseband ma o ka fiber optical i loko o ka band frequency nona ka mea hoʻohana.Hoʻouna ʻia ka hōʻailona kiʻekiʻe i ka antenna ma o ka mea hānai.Ma hope mai, no ka mea, ua ʻike ʻia he nui loa ka nalowale o ka hoʻouna feeder, inā hoʻokomo ʻia ka RFU i loko o ke kiʻi BBU a waiho ʻia i loko o ka lumi mīkini, a kau ʻia ka antenna ma kahi hale kiaʻi mamao, mamao loa ka mamao hoʻouna feeder a me ka nalowale. nui loa, no laila e lawe wale i ka RFU.E hoʻohana i ka fiber optical (ʻuʻuku ka liʻiliʻi o ka lawe ʻana i ka fiber optik) e kau ma luna o ka hale kiaʻi me ka antenna, no laila e lilo ia i RRU, ʻo ia ka ʻāpana lekiō mamao.
ʻO ka mea hope loa, ʻo ka antenna i ʻike pinepine ʻia e nā mea a pau ma nā alanui a me nā ala o ke kūlanakauhale, ʻo ia ka antenna e hoʻouna maoli i ka hōʻailona uila. i ka manawa like, a ʻoi aku ka nui o ka lawe ʻana i ka ʻikepili.
No nā antenna 4G, hiki ke ʻike ʻia a hiki i 8 mau ʻāpana transceiver kūʻokoʻa, no laila aia he 8 mau pilina ma waena o ka RRU a me ka antenna.Hiki ke ʻike maopopo ʻia nā ʻaoʻao 8 ma lalo o ka RRU 8-channel ma ke kiʻi ma luna, ʻoiai ke kiʻi ma lalo e hōʻike nei He antenna 8-kanal me 8 mau pilina.
Pono e hoʻopili ʻia nā 8 interfaces ma ka RRU i nā interface 8 ma ka antenna ma o 8 feeders, no laila hiki ke ʻike pinepine ʻia kahi puʻupuʻu o nā uea ʻeleʻele ma ka pou antenna.
