Usibye ingaruka zongerewe imbaraga zo kohereza imbaraga hamwe na antenne kunguka kubimenyetso byikimenyetso, gutakaza inzira, inzitizi, kwivanga n urusaku bizagabanya imbaraga za signal, ibyo byose bikaba bishira.Mugushushanya aumuyoboro muremure w'itumanaho, dukwiye kugabanya ibimenyetso bishira no kwivanga, kunoza ibimenyetso byerekana ibimenyetso, no kongera intera ikwirakwiza.
Ibimenyetso bishira
Imbaraga z'ikimenyetso kitagira umugozi zizagabanuka buhoro buhoro mugihe cyo kohereza.Kubera ko uwakiriye ashobora kwakira gusa no kumenya ibimenyetso simusiga bifite ibimenyetso byerekana ibimenyetso biri hejuru yurugero runaka, mugihe ibimenyetso bishira binini cyane, uwakiriye ntashobora kubimenya.Ibikurikira nibintu bine byingenzi bigira ingaruka kumyumvire.
Inzitizi
Inzitizi nicyo kintu gikunze kugaragara kandi cyingenzi mumiyoboro y'itumanaho idafite insinga zigira ingaruka zikomeye kumatwi.Kurugero, inkuta zitandukanye, ibirahuri, ninzugi byerekana ibimenyetso bidafite umugozi kurwego rutandukanye.Cyane cyane inzitizi zicyuma zishobora guhagarika rwose no kwerekana ikwirakwizwa ryibimenyetso bidafite umugozi.Kubwibyo, mugihe dukoresha amaradiyo yitumanaho adafite insinga, tugomba kugerageza kwirinda inzitizi kugirango tubone itumanaho rirerire.
Distance Intera yoherejwe
Iyo imiyoboro ya electromagnetique ikwirakwira mu kirere, uko intera yoherezwa yiyongera, imbaraga z'ikimenyetso zizagenda zishira buhoro buhoro kugeza igihe izimiye.Kwiyegereza inzira yo kohereza ni inzira yo gutakaza.Abantu ntibashobora guhindura agaciro k'ikirere, nta nubwo bashobora kwirinda ibimenyetso bitagira umuyaga bituruka ku kirere, ariko barashobora kwagura intera yo gukwirakwiza imiyoboro ya elegitoroniki yongerera imbaraga imbaraga zo gukwirakwiza no kugabanya inzitizi.Ubundi imiyoboro ya electromagnetique irashobora kugenda, mugari mugari sisitemu yohereza itagikoreshwa.
● Inshuro
Kuri electromagnetic waves, igihe kigufi cyumuraba, niko bigenda bishira.Niba inshuro zakazi ari 2.4GHz, 5GHz cyangwa 6GHz, kubera ko inshuro zabo ari ndende cyane kandi nuburebure bwumurongo ni bugufi cyane, kuzimangana bizagaragara cyane, mubisanzwe rero intera yitumanaho ntizaba kure cyane.
Usibye ibintu byavuzwe haruguru, nka antenne, igipimo cyo kohereza amakuru, gahunda yo guhindura, nibindi, bizanagira ingaruka kubimenyetso bishira.Kugirango ukurikirane intera ndende yo gutumanaho, byinshiIWAVE itumanaho ryamakuruifata 800Mhz na 1.4Ghz kuri videwo ya hd, ijwi, kugenzura amakuru hamwe no kohereza amakuru ya TCPIP / UDP.Zikoreshwa cyane kuri drone, ibisubizo bya UAV, UGV, gutegeka ibinyabiziga byitumanaho hamwe namaboko ya tactique ifata radiyo transceiver muburyo bugoye kandi burenze umurongo w'itumanaho.
Kwivanga
Usibye ibimenyetso byerekana ingaruka byabakiriye kumenyekanisha ibimenyetso bidafite umugozi, kwivanga n urusaku birashobora no kugira ingaruka.Ikigereranyo cyerekana-urusaku cyangwa ibimenyetso-byerekana-urusaku-urusaku rukoreshwa mugupima ingaruka zo kwivanga n urusaku kubimenyetso bidafite umugozi.Ikigereranyo cyerekana-urusaku nigipimo-cyo-kwivanga-urusaku ni cyo kintu nyamukuru cyerekana tekinike yo gupima ubwizerwe bw’itumanaho rya sisitemu yitumanaho.Umubare munini, ni byiza.
Kwivanga bivuga kwivanga guterwa na sisitemu ubwayo hamwe na sisitemu zitandukanye, nk'umuyoboro umwe uhuza hamwe no kwivanga kwinshi.
Urusaku bivuga ibimenyetso byinyongera bidasanzwe bitabaho mubimenyetso byumwimerere byakozwe nyuma yo kunyura mubikoresho.Iki kimenyetso kijyanye nibidukikije kandi ntigihinduka hamwe no guhindura ibimenyetso byumwimerere.
Ikigereranyo cyerekana-urusaku SNR (Ikimenyetso-cy-urusaku Igipimo) bivuga igipimo cyibimenyetso n urusaku muri sisitemu.
Imvugo yerekana ibimenyetso-by-urusaku ni:
SNR = 10lg (PS / PN), aho:
SNR: igipimo cyerekana-urusaku, igice ni dB.
PS: Imbaraga zingirakamaro zikimenyetso.
PN: Imbaraga zingirakamaro zurusaku.
SINR (Ikimenyetso cyo Kwivanga hiyongereyeho Urusaku rw'Urusaku) bivuga igipimo cy'ikimenyetso n'umubare w'ivanga n'urusaku muri sisitemu.
Imvugo yerekana ibimenyetso-kuri-kwivanga-urusaku ni:
SINR = 10lg [PS / (PI + PN)], aho:
SINR: Ikimenyetso-cyo-guhuza-urusaku-urusaku, igice ni dB.
PS: Imbaraga zingirakamaro zikimenyetso.
PI: Imbaraga zingirakamaro zikimenyetso kibangamira.
PN: Imbaraga zingirakamaro zurusaku.
Mugihe utegura no gushushanya umuyoboro, niba nta bisabwa bidasanzwe kuri SNR cyangwa SINR, birashobora kwirengagizwa byigihe gito.Nibisabwa, mugihe uyobora imbaraga zumurima wikigereranyo mugushushanya igishushanyo mbonera, ibimenyetso byo guhuza-urusaku bigereranywa bizakorerwa icyarimwe.
