M'zaka zaposachedwa, pofuna kupulumutsa ndalama ndi kuchepetsa kubwereza kwa zomangamanga, machitidwe ambiri ogawa m'nyumba atengera chitsanzo cha machitidwe ophatikizana ambiri omwe amagawana chipinda ndi ma sub-systems ena. Izi zikutanthauza kuti ma multi-system and multi-band signals amaphatikizidwa m'mapulatifomu ophatikizana komanso amagawidwa m'nyumba zogawanitsa kuti akwaniritse maulendo angapo, machitidwe ambiri, njira imodzi, kapena njira ziwiri.
Phindu lake ndikuchepetsa kubwereza kwa zomangamanga ndikusunga malo. Komabe, mavuto obwera chifukwa cha machitidwe ogawa m'nyumba otere akuyamba kukhala odziwika. Kugwirizana kwamitundu yambiri kumabweretsa kusokoneza kwadongosolo. Makamaka, magulu ogwiritsira ntchito pafupipafupi ndi ofanana, ndipo magulu apakati ndi ang'onoang'ono, kutulutsa kolakwika ndi PIM pakati pa machitidwe osiyanasiyana amakhudzidwanso.
Pamenepa, chipangizo chabwino chopanda phokoso chingachepetse zotsatira za kusokoneza uku. Chipangizo chopanda pake cha RF chokhacho chidzapangitsanso kutsika kwa zizindikiro zina zapaintaneti, ndipo zida zapamwamba kwambiri zidzakhala ndi zotsatira zabwino pamtundu wa netiweki, kuletsa kupezeka kwa mpweya woyipa, kusokoneza, komanso kudzipatula.
Mitundu yayikulu yosokoneza ma network opanda zingwe imagawidwa kukhala kusokoneza kwa dongosolo ndi kusokoneza kwapakati. Kusokoneza kwa dongosolo kumatanthawuza zosokera za gulu lopatsirana, zomwe zimagwera muzosokoneza za dongosolo lokhalo chifukwa cha gulu lolandira. Kusokoneza kwapakati pamakina ambiri kumakhala kutulutsa kwabodza, kudzipatula kwa olandila, ndi kusokoneza kwa PIM.
Kutengera ma netiweki wamba komanso momwe kuyezedwera, zida zongoyang'ana ndizofunikira kwambiri zomwe zimakhudza maukonde wamba.
Zinthu zazikuluzikulu zopanga chigawo chabwino chongokhala ndi:
1. Kudzipatula
Kudzipatula koyipa kungayambitse kusokoneza pakati pa machitidwe, kuwongolera kwa PIM yosokera ndi yonyamula zinthu zambiri, kenako kusokoneza chizindikiro chakumtunda.
2. VSWR
Pankhani ya VSWR yamagawo ocheperako ndi yayikulu, chizindikiro chowonekera chimakhala chokulirapo, zikavuta kwambiri malo oyambira amadziwitsidwa kuwonongeka kwa zinthu za RF ndi ma amplifiers.
3. Kukanidwa kunja kwa gulu
Kukanidwa koyipa kwakunja kudzakulitsa kusokoneza kwa machitidwe, koma luso loletsa kutsekereza, komanso kudzipatula kwa doko kumathandizira kuchepetsa kusokoneza pakati pa machitidwe.
4. PIM - passive Intermodulation
Zogulitsa zazikulu za PIM zimagwera mugulu lakumtunda zidzayambitsa kuwonongeka kwa magwiridwe antchito.
5. Mphamvu ya mphamvu
Pankhani ya zonyamulira zambiri, kutulutsa mphamvu kwamphamvu, ndi chizindikiro chapamwamba kwambiri, kusakwanira kwa mphamvu kumapangitsa kuti pakhale katundu wambiri. Izi zimapangitsa kuti intaneti ikhale yabwino kwambiri, zomwe zimapangitsa kuti arcing ndi moto. Pazovuta kwambiri, ndizotheka kuthyola kapena kuwotcha zida, zomwe zimapangitsa kuti network ya base station igwe.
6. Chipangizo processing ndondomeko ndi zipangizo
Zinthu zakuthupi ndi kukonza sikutsekedwa, zomwe zimatsogolera ku kuwonongeka kwa chipangizocho, pomwe kukhazikika kwa chipangizocho komanso kusinthika kwachilengedwe kumachepetsedwa kwambiri.
Kuphatikiza pazifukwa zazikuluzikuluzi, palinso zinthu zina monga izi:
1. Kuyika kutaya
Kutayika kwapang'onopang'ono kumapangitsa kuti chizindikirocho chiwononge mphamvu zambiri pa ulalo womwe umakhudza kufalikira, pamene kuwonjezeka kwa siteshoni yachindunji kudzayambitsa kusokoneza kwatsopano, ndikungowonjezera mphamvu yotumizira masiteshoni sikogwirizana ndi chilengedwe, ndipo kupitirira mzere wa amplifier ndi njira yabwino yogwiritsira ntchito. pamene khalidwe la ma transmitter lidzawonongeka, lidzakhudza kukwaniritsidwa kwapangidwe kagawidwe ka mkati.
2. Kusinthasintha kwamagulu
Kusinthasintha kwakukulu kumabweretsa kusayenda bwino kwa siginecha ya mkati mwa gulu, pakakhala zonyamulira zingapo zomwe zingakhudzire zomwe zikuchitika, ndikukhudza kukhazikitsidwa koyembekezeka kwa kapangidwe kagawidwe kanyumba.
Chifukwa chake, zida zomwe zimagwira ntchito zimathandizira kwambiri pomanga ma ae communication network base station.
Jingxin amayang'ana kwambirikukonza mwamakonda magawo ongokhalazofunika kwa makasitomala, kaya kuchokera kuwunika koyambirira, upangiri wapakatikati wanthawi yayitali, kapena kupanga mochedwa kwambiri, timatsatira mtundu woyamba, kuti tipereke chithandizo kwa makasitomala padziko lonse lapansi.
