Q-band ndi EHF-band: Kugwiritsa ntchito ndi ziyembekezo za ukadaulo wapamwamba kwambiri

Ma band a Q-band ndi EHF (Extremely High Frequency) ndi ma band ofunikira kwambiri mu electromagnetic spectrum, okhala ndi mawonekedwe apadera komanso ntchito zosiyanasiyana.

Gulu la Q:

Q-band nthawi zambiri imatanthauza kuchuluka kwa ma frequency pakati pa 33 ndi 50 GHz, komwe kuli mu EHF range.

Zinthu zake zazikulu ndi izi:

Mafupipafupi apamwamba: kutalika kwa nthawi yochepa, pafupifupi 6 mpaka 9 mm.

Kuthamanga kwakukulu: koyenera kutumiza deta mwachangu kwambiri.

Madera akuluakulu ogwiritsira ntchito Q-band ndi awa:

Kulankhulana kwa Satellite: kumagwiritsidwa ntchito polumikiza ndi kutsitsa makina a satelayiti apamwamba (HTS) kuti apereke ntchito za intaneti ya broadband.

Kulankhulana kwa maikulowevu pansi: kumagwiritsidwa ntchito potumiza deta patali komanso pamlingo wapamwamba.

Kupenda zakuthambo kwa wailesi: kumagwiritsidwa ntchito poona magwero a wailesi omwe amapezeka pafupipafupi kwambiri m'chilengedwe chonse.

Rada ya magalimoto: rada yapafupi yomwe imagwiritsidwa ntchito mu machitidwe apamwamba othandizira oyendetsa (ADAS).

Gulu la EHF:

Bandi ya EHF imatanthauza kuchuluka kwa ma frequency pakati pa 30 ndi 300 GHz ndipo kutalika kwa mafunde ndi 1 mpaka 10 mm, kotero imatchedwanso millimeter wave band.

Zinthu zake zazikulu ndi izi:

Ma frequency apamwamba kwambiri: amatha kupereka kuchuluka kwakukulu kwambiri kwa kutumiza deta.

Mzere wopapatiza: kukula kwa antenna kakang'ono komanso chitsogozo champhamvu.

Madera akuluakulu ogwiritsira ntchito gulu la EHF ndi awa:

Kulankhulana kwa asilikali: kumagwiritsidwa ntchito pa machitidwe olumikizirana omwe ali ndi zofunikira zambiri zachinsinsi, monga machitidwe a asilikali aku US a Milstar ndi Advanced Extremely High Frequency (AEHF).

Kulankhulana ndi Satellite: kupereka ntchito za intaneti yothamanga kwambiri komanso kuthandizira kutumiza deta mwachangu.

Machitidwe a radar: amagwiritsidwa ntchito pa ma radar ojambula zithunzi okhala ndi mawonekedwe apamwamba komanso ma radar owongolera moto.

Kafukufuku wa sayansi: amagwiritsidwa ntchito pozindikira mlengalenga ndi kuwona zakuthambo pa wailesi.

Mavuto ndi chitukuko:

Ngakhale kuti magulu a Q-band ndi EHF ali ndi mwayi waukulu wogwiritsa ntchito, akukumanabe ndi zovuta zina pakugwiritsa ntchito:

Kuchepa kwa mpweya: zizindikiro za mphepo zomwe zimatuluka pafupipafupi kwambiri zimakhudzidwa ndi zinthu zanyengo monga kuchepa kwa mvula panthawi yofalikira, zomwe zimapangitsa kuti zizindikirozo zichepe.

Kuvuta kwaukadaulo: Zipangizo zamagetsi zomwe zimagwiritsidwa ntchito pafupipafupi zimakhala ndi zofunikira kwambiri pakupanga ndi kupanga komanso zimakhala ndi mtengo wokwera.

Pofuna kuthana ndi mavutowa, ofufuza akupanga ukadaulo wapamwamba wosinthira ndi kulemba ma code, komanso njira zanzeru zosinthira njira kuti ziwongolere kudalirika kwa makina ndi kuthekera koletsa kusokoneza.

Mapeto:

Q-band ndi EHF-band zimagwira ntchito yofunika kwambiri pa kafukufuku wamakono wa mauthenga, radar ndi sayansi.

Ndi kupita patsogolo kwa ukadaulo, kugwiritsa ntchito ma frequency band awa kudzakulitsidwa kwambiri, zomwe zipereka mwayi watsopano wopititsa patsogolo madera osiyanasiyana.
