Q-band ndi EHF (Extremely High Frequency) ndi magulu ofunikira pafupipafupi pamagetsi amagetsi, okhala ndi mawonekedwe apadera komanso kugwiritsa ntchito kwakukulu.
Q-band:
Q-band nthawi zambiri imatanthawuza ma frequency pakati pa 33 ndi 50 GHz, yomwe ili mumtundu wa EHF.
Zina zake zazikulu ndi izi:
Mafupipafupi: kutalika kwafupipafupi, pafupifupi 6 mpaka 9 mm.
Ma bandwidth apamwamba: oyenera kutumiza mwachangu kwambiri.
Magawo ofunikira kwambiri a Q-band ndi awa:
Kuyankhulana kwa satellite: kumagwiritsidwa ntchito pokweza ndi kutsika kwa makina apamwamba a satellite (HTS) kuti apereke ntchito za intaneti za Broadband.
Kuyankhulana kwa ma microwave apansi: kumagwiritsidwa ntchito potumiza mtunda waufupi, wokwera kwambiri.
Radio astronomy: amagwiritsidwa ntchito kuyang'ana mawayilesi apamwamba kwambiri m'chilengedwe.
Radar yamagalimoto: radar yaufupi yomwe imagwiritsidwa ntchito pamakina othandizira oyendetsa (ADAS).
EHF gulu:
Gulu la EHF limatanthawuza ma frequency pakati pa 30 ndi 300 GHz ndipo kutalika kwa mafunde ndi 1 mpaka 10 mm, motero amatchedwanso millimeter wave band.
Zina zake zazikulu ndi izi:
Ma frequency apamwamba kwambiri: otha kupereka ziwopsezo zapamwamba kwambiri zotumizira deta.
Mtanda wopapatiza: kukula kwa tinyanga tating'ono komanso kuwongolera mwamphamvu.
Magawo akuluakulu ogwiritsira ntchito gulu la EHF ndi awa:
Mauthenga ankhondo: amagwiritsidwa ntchito ngati njira zoyankhulirana zokhala ndi chinsinsi chachikulu, monga zida zankhondo zaku US za Milstar ndi Advanced Extremely High Frequency (AEHF).
Kuyankhulana kwa Satellite: Kupereka mautumiki a Broadband ndikuthandizira kufalitsa kwa data kothamanga kwambiri.
Makina a radar: amagwiritsidwa ntchito popanga ma radar apamwamba kwambiri komanso ma radar owongolera moto.
Kafukufuku wa sayansi: amagwiritsidwa ntchito pozindikira zakuthambo komanso kuwunika zakuthambo pa wailesi.
Mavuto ndi zomwe zikuchitika:
Ngakhale magulu a Q-band ndi EHF ali ndi chiyembekezo chokulirapo, amakumanabe ndi zovuta pakugwiritsa ntchito:
Kutsika kwa mumlengalenga: ma siginecha okwera kwambiri amatha kutengeka ndi zinthu zakuthambo monga kuchepa kwa mvula panthawi yofalitsa, zomwe zimapangitsa kuti ma sign achepetse.
Kuvuta kwaukadaulo: zida zothamanga kwambiri zimakhala ndi mapangidwe apamwamba komanso zofunikira zopanga komanso zokwera mtengo.
Kuti athane ndi zovuta izi, ofufuza akupanga matekinoloje apamwamba kwambiri osinthira ndikusintha ma codec, komanso njira zanzeru zapakhomo zosiyanasiyana kuti apititse patsogolo kudalirika kwadongosolo komanso kuthekera kolimbana ndi kusokoneza.
Pomaliza:
Q-band ndi EHF-band zimagwira ntchito yofunika kwambiri pakulumikizana kwamakono, radar ndi kafukufuku wasayansi.
Ndi kupita patsogolo kwaukadaulo, kugwiritsa ntchito ma frequency awa kudzakulitsidwanso, kupereka mwayi watsopano wopititsa patsogolo magawo osiyanasiyana.
