mahi Modern taputapu kōrero me takere tatou hei takawaenga mo te kore noa tuku o ngā mōhiohio. E taea e ki te whakarato me te tautoko i te mahi o nga tikanga, me ngā pūrere, kaitirotiro i te mahi o ngā kaimahi ki te mamao whakahaere hangarau matatini ratou.

Mō ngā momo hononga i kua mea te rota. Ka whakarārangi noa matou ratou. Na, mo te whakawhiti raraunga , ka taea e koe te whakamahi i te waea, waea, reo irirangi, tangi pūnaha päpäho, pouaka whakaata, amiorangi me kōrero pūkoro, ngā hōputu hou (3G, 4G, me ētahi atu), whaiaho rorohiko me whatunga ahokore. I roto i tenei take, kei te whakawhetai ki te whanaketanga o hangarau i roto i te mara o te kōrero, me te whakawhitinga, te kounga me te auau moka te whakanui ake. He nui tūranga i roto i tenei hononga tākaro. I a ratou e te kōrero.

Types me whakarōpū o takere kōrero

I mua i te kōrero e tatou e pā ana ki te momo o, hanga ana e ia tikanga ki te tautuhi i te ngako o "takere kōrero" ariā. E pā ana te reira ki te pūnaha tënei o te reo i roto i nei te whakatö o te tohu, me o nga whakaaro hangarau me taputapu e whakarato me te tautoko i te whakatö o te tohu o te tetahi auau i te tetahi tere.

Ki te whakaaro ki te whakarōpūtanga typology ranei, he mea i teie nei e taea te wehea nga takere kōrero e whai ake:

• Na roto i te momo o te reo conductive (taura ranei auau irirangi).
• Na roto i te awhe auau (HF, VHF, UHF, ropu ngaruiti, mirimita pēne, pōkākā).
• E ai ki te momo tohu (tairitenga mamati ranei).

E rave rahi Kua rongo pea ngā pērā i takere kōrero mamati takere optical ranei. He aha e ratou āhuatanga motuhake painga ranei?

takere Digital tuku mōhiohio i roto i te puka o te waehere-rua, i te mea Kei o 0 me 1. anake Ki tenei hangarau, ko reira taea ki te whakatutuki i te mate iti ranei te pirau o ngā raraunga, i roto i te rerekē ki te tikanga tairitenga. Hei tauira, ka korero i runga i te waea te pinepine whakamahia tohu tairitenga parau tumu whakahaere o te mea tonu i roto i te whakawhitinga o oscillations hiko. Ko reira no te mea he tino haria ki te pokanoa te pūnaha tairitenga o te utu mōhiohio me taea tino ketia mōhiohio ki te ngaro raraunga ranei.

He rerekē i ētahi atu rauemi iho, i hanga i nei te taura hononga ōmata. muka Optical whakamahia i roto i to ratou hanga, ka taea ki te whakarato hōkaiipurangi tiketike, iti distortion tohu whakaiti ranei noa i tawhiti nui, mate ki te raweketia. I tua atu, he nui te iti me te mama i roto i ona te muka i roto i te utu production āhuatanga whānui. E ai ki etahi puna, te taimaha o ngā taura tikanga e taea e 10 ngā wā i te taimaha o conductors optical rahi rite o. hononga Optical He mamati rite ngā mōhiohio tuku i roto i tenei puka e rua.

E kore e taea e tatou te mea e pā ana ki te teihana ahokore. Etahi o ratou whakamahi tatou, kahore noa whakaaro e pā ana ki reira. He tauira o tenei pea he pōkākā (taiaho) teihana. āhei te reira ki a tatou te whakahaere i te TV atu pūrere ranei ki te mamao, e homai i te kurupae whakahaua o te marama. Hoki ngā hononga ahokore ngā:

• Pōkākā taiaho ranei.
• whāngai Microwave (whakamahia hoki amiorangi LD ranei).
• whatunga reo irirangi Free (taea o te tohu te tuku i roto i te maha o ngā here).
