Isikhulisi se-Trunk Line ekhethwayo se-UHF TETRA engabizi kakhulu ukuze ifakwe ngaphakathi kwe-DAS

I-China ehamba phambili ye-UHF/TETRA Repeater 5W 10W 20W 30W Abakhiqizi Nabahlinzeki- I-Kingtone ihlinzeka ngekhwalithi ephezulu I-UHF TETRA Isiteshi Sokukhetha I-Trunk Line Amplifier yokufakwa kwangaphakathi kwe-DAS.

I-UHF / TETRA BDA yakhelwe ukuhlinzeka ngesixazululo esingabizi kakhulu kunokwengeza i-Base Station (BS) entsha ukuze kuthuthukiswe ukumbozwa kwesignali futhi i-UHF / TETRA Line Amplifier (LA) isetshenziselwa ukunweba indawo yokufakwa ohlelweni lwe-antenna lokusabalalisa ( I-DAS) exhuma ngamakhebuli angama-coaxial ukuze ifakwe ngaphakathi endlini yokuthuthukisa isignali ukuze inikeze ukuxhumana okuthembekile nabasebenzisi bomsakazo (I-Portable).

Sekela uhlelo lwe-UHF / TETRA, njenge:

I-Uplink: 380-385MHz, i-Downlink: 390-395MHz;

I-Uplink: 410-415MHz, i-Downlink: 420-425MHz;

Isikhulisi se-Trunk singafinyelela ukukhuliswa okuphindwe kabili kwesignali ye-uplink ne-downlink, ithuthukise ikhwalithi yokukhuluma, futhi itholakale indawo eyimpumputhe yokwandisa nokugcwalisa isignali, inwebe ububanzi bokuhlanganisa.Isetshenziswa ngempela ukulinganisa ukulahleka kwesignali kwezintambo zesiqu ze-Micro-honeycomb Indoor Distribution System kanye ne-Wireless Connection Indoor Distribution System.
