Niba wigeze gukoresha itumanaho rya RF (radio frequency), imiyoboro ya telefoni zigendanwa, cyangwa sisitemu za antene, ushobora guhura n'ijambo "LMR cable". Ariko se ni iki mu by'ukuri kandi kuki ikoreshwa cyane? Muri iyi nkuru, turasuzuma icyo "LMR cable" ari cyo, imiterere yayo y'ingenzi, n'impamvu ari yo ikundwa cyane muri porogaramu za RF, hanyuma dusubize ikibazo 'LMR cable ni iki?'.
Sobanukirwa n'insinga ya LMR coaxial
Insinga za LMR ni insinga ya coaxial yagenewe kohereza ibimenyetso mu buryo bworoshye kandi butangiza cyane mu bikorwa bya RF. Insinga za LMR zikorwa na Times Microwave Systems kandi zizwiho kurinda neza, gutakaza ibimenyetso bike, no kuramba kwazo, bigatuma ziba nziza kuri GPS y'itumanaho ridafite umugozi, Amahitamo meza kuri radar n'izindi sisitemu zishingiye kuri RF. Bitandukanye n'insinga za coaxial zisanzwe, insinga za LMR zakozwe zifite ibice byinshi by'ibikoresho byo kurinda no kwangiza ibimenyetso kugira ngo zirusheho kuba nziza. Ziza mu bunini butandukanye bwo guhitamo, nka LMR-195, LMR-240, LMR-400, na LMR-600, buri imwe yagenewe gutunganya ingufu no gutakaza ibimenyetso bitandukanye.
Ibiranga by'ingenzi bya LMR coaxial cable
Insinga za LMR zigaragara cyane mu bijyanye n'insinga za coaxial bitewe n'imiterere yazo yihariye n'akamaro kazo:
1. Kubura ikimenyetso ku rugero ruto
Kimwe mu byiza by'ingenzi by'insinga za LMR zifite igihombo gito cy'amajwi ni ukudahita kwazo mu ntera ndende (igihombo cy'amajwi). Ibi bigerwaho binyuze mu gukingira no gukingira amashanyarazi mu buryo bwiza, bigabanya igihombo cy'ingufu iyo ibimenyetso binyura mu nsinga.
2. Imikorere myiza cyane yo kurinda
Igishushanyo mbonera cy'insinga za LMR gifite ibice byinshi byo kuzikingira, ubusanzwe harimo n'uburinzi bwa aluminiyumu bwo kurinda EMI y'ibanze (interference electromagnetic). Kuboha uburinzi bwo hanze byongera kuramba kandi bigabanya interference. Ubu burinzi butuma ibimenyetso bikomeye kandi byumvikana neza, bigatuma insinga za LMR ziba amahitamo meza ku bikoresho bya RF byoroheje.
3. Kuramba no kwihanganira ikirere
Times Microwave Systems ikora insinga za LMR, zifite icyuma gikomeye cyo hanze gikozwe muri polyethylene (PE) cyangwa thermoplastic elastomer (TPE), bigatuma zidahura n'imirasire ya ultraviolet, ubushuhe, n'ubushyuhe bukabije. Hari ubwoko bumwe na bumwe, nka LMR-UF (Ultra Flex), butanga uburyo bworoshye bwo gushyiraho ibintu bisaba gupfunyika no kugenda kenshi.
4. Gushyiraho byoroshye kandi byoroshye
Ugereranyije n'insinga zisanzwe zikomeye za coaxial, insinga za LMR zifite ubworoherane bwinshi kandi zoroshye, bigatuma gushyiraho byoroha. Umwanya wazo wo kugonda ni muto cyane ugereranyije n'insinga za RF zisa, bigatuma zishobora gushyirwa mu mwanya ufunze neza.
5. Guhuza neza n'ibihuza RF
Insinga za LMR zishyigikira imiyoboro myinshi, harimo imiyoboro yo mu bwoko bwa N (ikoreshwa cyane muri porogaramu za antene na RF). Umuyoboro wa SMA (kuri sisitemu zitagira umugozi na GPS). Umuyoboro wa BNC (ukunzwe cyane mu gusakaza no gukoresha interineti). Uku guhuza ibintu bituma zikoreshwa cyane mu nganda zitandukanye.
Imikoreshereze isanzwe y'Insinga za LMR
Kubera imikorere yayo myiza, insinga za LMR zikoreshwa cyane mu nganda zikoresha itumanaho rya RF. Zimwe mu porogaramu zikunze gukoreshwa zirimo imiyoboro ya telefoni zigendanwa zidafite insinga, antene na RF, itumanaho rya GPS na satelite, porogaramu z’indege, uburyo bwo kugenzura no kurinda.
Hitamo insinga ya LMR ikwiye
Guhitamo ubwoko bukwiye bwa LMR biterwa n'ibintu byinshi, harimo inshuro, intera, uburyo bwo gukoresha ingufu, n'imiterere y'ibidukikije. Dore amwe mu mahitamo asanzwe:
LMR-195 na LMR-240: Bikwiriye gukoreshwa mu ntera ngufi nka antene za Wi-Fi na sisitemu za GPS.
LMR-400: Uburyo bwo gutakaza make hagati bukunze gukoreshwa muri sisitemu za radiyo zigendanwa n'iz'inzira ebyiri.
LMR-600: Irakwiriye cyane gukoreshwa mu ntera ndende aho igihombo cy'ikimenyetso kigomba kugabanuka cyane.
Niba ukeneye koroshya porogaramu za telefoni zigendanwa, insinga ya LMR-UF (Ultra Flex) nayo ni amahitamo meza.
