Ikhebula le-AISG lokuxhuma i-8 Pin Port Jumper Control DB9 Owesifazane Owesilisa

Kuyini i-AISG?
I-Antenna Interface Standards Group (AISG) idala futhi igcina amazinga esixhumi sokulawula nokuqapha phakathi kwesiteshi sesisekelo kanye nemishini eyahlukahlukene ye-tower-top. Lokhu kufaka phakathi ama-antenna ane-remote electrical tilt (RET), ama-amplifier afakwe kwi-tower kanye nezinzwa ezahlukahlukene ezisetshenziselwa ukuqapha ukusebenza kwemishini ye-tower-top. Lezi zibizwa ngokuthi ama-subunit. Uhlu oluphelele lwalawo asekelwayo njengamanje lungatholakala lapha.
Izindinganiso zifaka phakathi izendlalelo ze-PHY ezihlukile, ibhasi le-RS-485 kanye nohlelo lwe-OOK olusebenzisa isignali yemvamisa yomsakazo ye-MF edluliselwa ngaphakathi kwezintambo ze-coaxial ezijoyina ama-antenna, ama-amplifier kanye neziteshi eziyisisekelo.
Inguqulo yakamuva yezindinganiso (v3.0) inikeza amadivayisi anezimbobo zokulawula eziningi ezingaxhunywa ngakunye kubalawuli abahlukene (ngokuvamile iziteshi eziyisisekelo), kanye nekhono lomlawuli lokuhlanganisa ukuxhumana kwesistimu ye-RF phakathi kwamadivayisi axhunywe ebhasini. Izinga liqukethe izinga eliyisisekelo kanye nezindinganiso zohlobo ngalunye lweyunithi encane.
