RF POI imayimiraRF Point ya Interface, chomwe ndi chipangizo cholumikizirana ndi matelefoni chomwe chimaphatikiza ndikugawa ma siginecha angapo a wailesi (RF) kuchokera kwa ogwiritsa ntchito maukonde osiyanasiyana kapena machitidwe popanda kusokoneza. Imagwira ntchito posefa ndi kuphatikizira ma siginecha kuchokera kumagwero osiyanasiyana, monga malo oyambira oyambira osiyanasiyana, kukhala chizindikiro chimodzi, chophatikizika cha pulogalamu yolumikizira m'nyumba. Cholinga chake ndikupangitsa maukonde osiyanasiyana kuti agawane zomanga zamkati zomwezo, kuchepetsa ndalama komanso zovuta ndikuwonetsetsa kuti ma siginecha odalirika amaperekedwa pazinthu zingapo monga ma cellular, LTE, ndi kulumikizana kwachinsinsi.
Momwe zimagwirira ntchito
• Uplink: Imasonkhanitsa ma siginecha kuchokera ku mafoni a m'manja mkati mwa dera ndikutumiza ku masiteshoni oyambira pambuyo powasefa ndi kuwalekanitsa ndi ma frequency ndi oyendetsa.
• Downlink: Imapanga zizindikiro kuchokera kwa ogwira ntchito angapo ndi maulendo afupipafupi ndikuwaphatikiza kukhala chizindikiro chimodzi kuti chigawidwe m'nyumba yonse kapena m'deralo.
• Kupewa kusokoneza: POI imagwiritsa ntchito zosefera zapamwamba ndi zophatikizira kuti zilekanitse ndi kuyang'anira ma sigino, kuletsa kusokoneza pakati pa maukonde osiyanasiyana a operekera.
Gawo la RF POI lingaphatikizepo:
| Chigawo | Cholinga |
| Zosefera / Duplexers | Gwirani njira za UL/DL kapena ma frequency osiyanasiyana |
| Othandizira | Sinthani milingo yamphamvu kuti mufanane |
| Zozungulira / Zodzipatula | Pewani zowunikira zazizindikiro |
| Ogawa Mphamvu / Ophatikiza | Gwirizanitsani kapena kugawa njira zazizindikiro |
| Directional Couplers | Yang'anirani kuchuluka kwa ma siginoloji kapena konzani njira |
RF POI imadziwika ndi mayina ena angapo kutengera dera ndi ntchito. Mayina ena odziwika kwambiri ndi awa:
| Nthawi | Dzina lonse | Tanthauzo / Kagwiritsidwe Ntchito |
| RF Interface Unit | (RF IU) | Dzina lachidziwitso lachigawo chomwe chimagwirizanitsa magwero angapo a RF ndi DAS. |
| Multi-Operator Combiner | MOC | Ikugogomezera kuphatikiza zonyamulira angapo / oyendetsa. |
| Multi-System Combiner | MSC | Lingaliro lomwelo, lomwe limagwiritsidwa ntchito pomwe chitetezo cha anthu + chamalonda chimakhalira limodzi. |
| MCPA Interface Panel | MCPA = Multi-Carrier Power Amplifier | Amagwiritsidwa ntchito pamakina olumikizana ndi MCPA kapena BTS. |
| Mutu-End Combiner | - | Amagwiritsidwa ntchito m'zipinda zam'mutu za DAS asanagawane ma sign. |
| POI Combiner | - | Kusintha kwachindunji kosavuta kwa mayina. |
| Signal Interface Panel | SIP | Kutchula mayina amtundu wamba, nthawi zina amagwiritsidwa ntchito pachitetezo cha anthu DAS. |
Monga katswiri wopangaZigawo za RF, Apex sikuti imangopereka magawo amtundu uliwonse pazogwiritsa ntchito zosiyanasiyana, komanso imapanga ndikuphatikiza RF POI monga chofunikira kwa kasitomala. Chifukwa chake ngati mukufuna zina zambiri, ndinu olandiridwa kuti mutilankhule.
