Mphamvu ya kuwala kofooka kwa ONU pa liwiro la netiweki

ONU ndi chomwe nthawi zambiri timachitcha "katswiri wopepuka", kuwala kochepa kwa ONU kumatanthauza chodabwitsa chakuti mphamvu yowunikira yomwe ONU imalandira ndi yocheperako kuposa mphamvu yolandirira ya ONU. Kuzindikira kolandila kwa ONU kumatanthauza mphamvu yocheperako ya kuwala yomwe ONU ingalandire panthawi yogwira ntchito bwino. Nthawi zambiri, chizindikiro cha kukhudzidwa kolandira cha ONU yapakhomo ndi -27dBm; chifukwa chake, mphamvu yolandirira ya ONU yocheperako kuposa -27dBm nthawi zambiri imatanthauzidwa ngati kuwala kofooka kwa ONU.

Pali zinthu zambiri zomwe zimakhudza zomwe wogwiritsa ntchito akugwiritsa ntchito pa intaneti. Kuwala kochepa kwa ONU kumakhudza kwambiri liwiro la netiweki. Pofuna kuyesa momwe kuwala kofooka kwa ONU kumakhudzira liwiro la netiweki ya wogwiritsa ntchito, Laodingtono adapanga chitsanzo chotsatirachi choyesera.

Lumikizani chochepetsera mphamvu chosinthika ndi choyezera mphamvu cha PON motsatizana pakati pa chingwe chachikopa ndi ONU, kuti choyezera mphamvu cha PON chigwiritsidwe ntchito kuyeza mphamvu ya kuwala yolandiridwa ya ONU (mphamvu ya kuwala yotsika ya mayeso). Kusiyana pakati pa mphamvu ya kuwala yolandiridwa ya ONU ndi pafupifupi 0.3dB (jumper imodzi ya ulusi kupatula kuchepa kwa kulumikizana kogwira ntchito). Malo enieni oyesera ali motere.

Mwa kusintha kuchepetsedwa kwa chochepetsera chosinthika, kuchepetsedwa kwa ulalo wa ODN kumatha kuwonjezeka, ndipo mphamvu yowunikira yolandiridwa ya ONU ikhoza kusinthidwa. Kusintha kwa liwiro la netiweki kumayesedwa polumikiza laputopu ku ONU ndi chingwe cha netiweki. Njirayi imagwiritsidwa ntchito poyesa broadband ya 300M ya Laodingtoujia, ndipo zotsatira za mayeso ndi izi.

Kuzindikira kwenikweni kwa ma ONU ambiri nkwabwino kuposa index ndi pafupifupi 1.0dB. Mwachitsanzo, ma ONU omwe ali mu mayesowa amatha kugwirabe ntchito bwino ngati mphamvu yowunikira yolandira ili pamwamba kuposa -27.98dBm. Mphamvu yowunikira yolandiridwa ikatsika kuposa -27.98dBm, liwiro la netiweki ya downlink limatsika mwachangu ndi kuchepa kwa mphamvu yowunikira yolandiridwa, ndipo imasunga liwiro lotsika kwambiri la netiweki mkati mwa mphamvu inayake yowunikira mpaka netiweki itasokonezedwa kwathunthu.
