Kugwiritsa ntchito Duplexers mu Indoor Distribution Systems

Chifukwa cha kuchuluka kwa mauthenga okhudzana ndi chitetezo cham'manja ndi pagulu, makina a indoor distributed antenna (DAS) amagwiritsidwa ntchito kwambiri m'malo monga ma eyapoti, njanji zapansi panthaka, zipatala, ndi malo akuluakulu ogulitsa kuti athe kuthana ndi malo osawona m'nyumba komanso kutsika kwa ma sign. Pakati pazigawo zambiri zofunika mu machitidwe a DAS, ndiduplexerndi gawo lofunikira komanso lofunikira.

Theduplexer'sntchito yayikulu ndikupangitsa ma sign a uplink ndi downlink kuti agawane mlongoti womwewo, kulekanitsa bwino mazizindikiro awiriwa kudzera pakupanga kwapadera kodzipatula kuti asasokonezedwe. Izi zimapereka zabwino zotsatirazi mu machitidwe a DAS:

Kuchepetsa chiwerengero cha antenna: Ma antenna omwe amagawidwa amachepetsa kwambiri zovuta zoikamo ndi mtengo wa cabling;

Kupititsa patsogolo khalidwe lazizindikiro: Kusunga kulankhulana kokhazikika m'madera ambiri, magulu ambiri;

Imathandizira kutumizidwa kwamitundu ingapo: Kaya muchitetezo cha anthu DAS, nyumba zamalonda, kapena ma network ambiri ogawana nawo,duplexersakhoza kuchita modalirika.

M'makina olumikizana ndi chitetezo cha anthu,duplexersonetsetsani kulumikizana kosalala kwa VHF/UHF kwa apolisi, ozimitsa moto, ndi mauthenga azachipatala. M'malo akuluakulu azamalonda, amachepetsa kuchuluka kwa zida ndikuwongolera kufananiza. M'malo ovuta ngati ma eyapoti ndi ma subways,duplexersthandizirani kukwaniritsa kudzipatula koyenera komanso kulumikizana kosasunthika kwa ma siginecha amitundu yambiri.

Ndi kudzipatula kwakukulu, kutayika kochepa koyikapo, mphamvu yamphamvu yogwiritsira ntchito mphamvu, ndi mapangidwe osinthika,duplexerskuonetsetsa kuti machitidwe a DAS akugwira ntchito kwambiri m'madera omwe miyezo ingapo, monga LTE, 5G, ndi chitetezo cha anthu zimakhalira limodzi. Iwo ndi zigawo zofunika kwa masiku ano m'nyumba kulankhulana Kuphunzira.
