Imikhiqizo
Umhlangano wokuhlukanisa amandla we-RF POI
| Umholi-mw | Isingeniso senhlangano yokuhlukanisa amandla ye-POI |
1. Ukuze kusetshenziswe kaningi izinhlelo ze-antenna zangaphandle kanye nokumbozwa kwangaphakathi, kuyadingeka ukuhlanganisa amasignali avela eziteshini zokuxhumana zeselula zabaqhubi abaningana namanethiwekhi.
I-2.POI isetshenziselwa ukuhlanganisa iziteshi zokuxhumana zeselula ezingaphezu kwezintathu ezinemvamisa ehlukene, ngaleyo ndlela ivumela abahlinzeki bezinsizakalo abaningana ukuthi basebenzise ndawonye izintambo eziningi ze-antenna feeder noma ama-antenna amaningi.
I-3.POI isetshenziselwa ukuhlanganisa izimpawu zeziteshi ezimbili noma ngaphezulu kuma-antenna amaningi.
