I. Isano iri hagati ya 5G Smart Light Pole hamwe nibicuruzwa bya Crystal Oscillator
Igishushanyo mbonera cyo mumijyi kirimo kuvugururwa. Ibisanzwe - bisa nkibiti byoroheje bigenda bihindagurika bucece mubice byinshi - bikora 5G byoroheje byamatara yubwenge, bihuza itumanaho rya 5G, itara ryubwenge, gukurikirana ibidukikije, kugenzura umutekano, kwerekana amakuru, nibindi byinshi - ni impera zingirakamaro zumujyi wubwenge.
Ariko, inyuma yibi sisitemu igoye kandi ihanitse, ituze, itomoye, kandi yiringirwa nibisabwa byingenzi. Guhuza neza kwa buri module ikora, nyayo - yohereza igihe cya buri data packet, hamwe nogukora neza kwa buri tegeko byose bishingikiriza kumurongo wicecekeye ariko wingenzi.
ibigize: uburebure - busobanutse bwa quartz kristal oscillator, bakunze kwita "kristu oscillator."
II. Nibihe bikorwa kuri 5G Byoroheje Byumucyo Ukoresha Crystal Oscillators?
