Inzira zibiri-Ibarabara ry'iradiyo n'ibintu biyigirako ingaruka

Amaradiyo y'inzira zibiri-, azwi kandi nka walkie-talkies, ni ibikoresho bishobora gutuma umuntu ashobora guhanahana amakuru ataco yizigiye ku nzira z'amatelefone ngendanwa. Bikoreshwa cane mu mutekano wa bose, mu bucuruzi no mu bikorwa vyo hanze. Urutonde rwavyo rurashikirwa n’ibintu bitandukanye, kandi gutahura ivyo bintu birashobora kugufasha kubihitamwo no kubikoresha neza.

Ivyiyumviro vy'amaradiyo y'inzira zibiri -mu bisanzwe biva ku bilometero bikeyi gushika ku bilometero mirongo, ariko mu bikorwa, akenshi ni bigufi cane. Mu bihe vyiza, nk’ibiyaya vyuguruye, bitagira inzitizi canke mu bibanza vy’uburebure burenze, ibikoresho vy’umwuga bifise ibikoresho vy’ugutanga amakuru vy’ububasha bwinshi-n’ama antene akora neza birashobora gushika ku bilometero mirongo. Ariko rero, mu bidukikije bikomeye nk’ibibanza vyubatswe cane-, mu misozi, canke mu mashyamba, uguhagarika ikimenyetso n’uguhungabana kw’inzira nyinshi birashobora kugabanya urugendo rwiza rwo gushika ku metero amajana canke mbere n’ibindi.

Inguvu z’ivyo bikoresho ni ikintu nyamukuru co kumenya urugero. Mu kuvuga muri rusangi, ububasha bwinshi bisigura urugendo runini rwo gutanga ikimenyetso. Ivyuma vy’abasivile-bikoresha ubushobozi bw’amawatt 0,5 gushika kuri 2, mu gihe ibikoresho vy’abahinga bishobora gushika ku mawatt 5 canke birenze. Ubwoko bw’antene n’uburebure bwayo na vyo nyene birahambaye. Antene z'inzira zifise inyungu nyinshi-zituma ubushobozi bwo guhanahana amakuru butera imbere cane, kandi gushiramwo antene nyinshi bituma ikimenyetso gishobora gukwiragira.

Ibintu vy'ibidukikije ntibishobora kwirengagizwa mu kugira ico bikoze ku rutonde rw'amaradiyo y'inzira zibiri-. Ubukonje, imvura n’urubura birashobora gufata imipfunda imwe imwe y’iradiyo, mu gihe uguhungabana kw’umuyagankuba (nk’akarorero, kuva ku mirongo y’umuyagankuba y’umuyagankuba mwinshi-n’ibikoresho vy’umuyagankuba) bishobora gutuma ikimenyetso kigabanuka. Ikindi kandi, guhitamwo incuro ni ikintu gihambaye cane. VHF (incuro nyinshi cane, 30-300MHz) ifise uburebure bw’umuvuduko burebure kandi ifise ubushobozi bwo kwinjira mu mubiri bugoyagoya ariko ikaba ifise ubushobozi bwo guca ibibatsi bukomeye, ivyo bikaba bituma ibereye ahantu hafunguye. UHF (ultra-high frequency, 300-3000MHz) ifise uburebure bw’umuvuduko bugufi kandi ishobora kwinjira cane ariko irazibirwa bitagoranye n’intambamyi, bikaba bituma ishobora gukoreshwa mu bisagara.

Mu ncamake, urutonde rw'itumanaho rw'iradiyo y'inzira zibiri-si agaciro kadahinduka; bigenwa n’uguhuza ibipimo vy’ibikoresho, ivy’ibidukikije, n’uguhitamwo incuro. Abakoresha bakwiye guhindura uko ibikoresho vyabo biteye bivanye n’ivyo bakeneye vy’ukuri kugira ngo bashobore kuvugana neza.
