Chingwe cha AISG Cholumikizira cha Ma Pin 8 Port Connection Jumper Control DB9 Yaimuna Yaikazi

Kodi AISG ndi chiyani?
Gulu la Antenna Interface Standards Group (AISG) limapanga ndikusunga miyezo yolumikizirana ndi kuyang'anira pakati pa siteshoni yoyambira ndi zida zosiyanasiyana za tower-top. Izi zikuphatikizapo ma antenna okhala ndi remote electrical tilt (RET), ma amplifiers okwera pa tower ndi masensa osiyanasiyana omwe amagwiritsidwa ntchito kuyang'anira momwe zida za tower-top zimagwirira ntchito. Izi zimatchedwa ma subunits. Mndandanda wathunthu wa omwe akuthandizidwa pano ungapezeke apa.
Miyezoyi ikuphatikizapo zigawo zina za PHY, basi ya RS-485 ndi makina a OOK pogwiritsa ntchito chizindikiro cha ma radio-frequency cha MF chomwe chimatumizidwa mkati mwa zingwe za coaxial zomwe zimalumikizana ndi ma antenna, ma amplifiers ndi malo oyambira.
Mtundu waposachedwa wa miyezo (v3.0) umapereka zida zokhala ndi madoko angapo owongolera omwe angalumikizidwe ndi owongolera osiyanasiyana (nthawi zambiri malo oyambira), komanso kuthekera kwa wowongolerayo kuyika maulumikizidwe a RF system pakati pa zida zolumikizidwa ndi basi. Muyezowu umaphatikizapo muyezo wa maziko pamodzi ndi miyezo ya mtundu uliwonse wa subunit.
