Torotoro waea Modern - he hononga nohopuku

Ko te mākete torotoro waea ko tetahi o te wāhi tino whaihua, me te tere tipu o te ahumahi torotoro waea. I tēnei wā, ko te pūnaha torotoro waea i runga i te ara o te whanaketanga tere, i roto i te whānui, kua arotahi ki runga ki te tomokanga pūnaha kōrero Russian ki te ao hei hoa rite ki te whakarato ratonga o te ao, roa-tawhiti, pa, raraunga, ipurangi, pūkoro, etc ..

He aha te mea te Telecommunications

Ko te wā "aratuku" ahu te i te kupu: communico Latin, e te tikanga "ahua o kōrero," me te tele Kariki, te tikanga "mahi i te tawhiti nui."

Na, ka taea e tatou te mea e:

• Telecommunications - he kohinga o ngā pūrere me ngā hōtaka ki te tuku mōhiohio mā taura me te reo irirangi takere. Tenei pūrere mōhiohio faafariuraa, tona wetemuna, puoro; Tenei matatau hangarau tukatuka rorohiko.
• taputapu Telecommunications - he huinga o hangarau, pūmanawa me te tikanga whakahaere mo te tuku o ngā raraunga i runga i tawhiti roa. E whakamahia mārō-kāwanatanga amplifiers putanga ki te waihanga i te ongoi e teihana pee'utari.
• Ko te ahei o te whakawhitihia me te whiwhi karere mana Center Ratonga - torotoro waea. Mataotao i roto i torotoro waea - tikanga me Engineers. Ratou nuinga mahi ki waehere, tohu, haruru.
• Telecommunications - Ko te utu o tetahi mōhiohio ki te awhina o te rorohiko. tuku mōhiohio e roto i te takere kōrero whakawhitiwhiti mōhiohio ranei.
• Telecommunications - Ko te tukanga o te whiwhi me te tukatuka pārongo mā te whakamahi i hiko, whatunga, hiko, ngā mōhiohio me ngā hangarau rorohiko.

kia whakaaro wāhanga fafau o hangarau torotoro waea:

1. Waihanga Ngā Hanganga tohu-waehere hou i te whakamahi o ngā tūāhua ngā o tohu whawhe me tikanga whakawaehere tohu hou ki te whakapiki ake i ngā pūnaha hōkaiipurangi me te tuku ki te whakapai ake i to ratou kaha.
2. Te hanga i te whakaaro pūihi atamai ki ake te kaha.
3. Creation o ngā pūnaha aratuku i roto i te mirimita pēne poipoi ki te auautanga mahi o āhua 100 GH.
4. Whanaketanga o ngā tikanga me ngā hangarau o te torotoro waea taputapu, e whakarite ratou mahi tino pai o te paearu whānui: te utu mōkito, tawhā mōrahi, tika mōrahi, taimaha iti me ngā āhuatanga rahi.
5. Te whakanui ake i te taumata o te whakangungu o ngā ākonga i roto i te ahunga o "Telecommunications", te roha o te rangahau me te whanaketanga i roto i te ahunga.

He whakawaehere Hangarau tikanga tohu

Hoki pūngao tino pai whakamahi pūnaha nga tikanga hōu o te whakawaehere me te tohu puoro. E tohu waehere tikanga ki te aro hapa i roto i nga tikanga pokanoa, whakarato mahi pūngao taonga o te pūnaha ki te 6.8 DB, ahakoa te tohu horapa tūāwhiorangi. whakamahi te reira i waehere poraka: waehere Hamming, Reed-Horomona, BCH me waehere convolutional rakau. He whakamahi ngā o waehere he tika ki te whakaaro e tukua ki te ite wā kaha tīwera tapatoru neke hiki me te kupu whiwhi atu taonga waehere ki te whakapiki ake i te tere tohu tuku. I roto i tenei take i te whakamahi hōkaiipurangi hongere maha-tūnga wāhanga whanaunga neke hiki me te quadrature tīwera wāhanga neke hiki.

kōrero amiorangi

E whakamahia ngā pūnaha amiorangi kōrero i roto i āmiorangi mautū mo te tuku o ngā hōtaka pouaka whakaata, tae atu ki ngā farii takitahi me te rōpū pūmanawa hokohoko raraunga. O ngā tuhipoka ko te pūnaha ao o te whakatere moana Inmarsat amiorangi,, ano, kua riro nei whakamahi arumoni whānui mō te kōrero tere, me te whakatere te whakamahi i te pūnaha navigation amiorangi GPS i roto i ngā wāhi mamao, i roto i ohorere, kia rite ki te pai kia rite ki hoki te aroturuki o te utanga waka. Kiato waea pee'utari taea whakawhiti o ngā raraunga i hea i roto i te ao. I roto i te i ngā ki te aunui tupurangi haruru tohu kua whakatinanahia hangarau hou: te pūihi auau microstrip, he mārō āhua mana tīwerawera, he tātari hongere rua i roto i te ngaru mata oro e hāngai ana i runga i germanate bismuth, ngā tātari ngaruiti narrowband i roto i resonators uruhanga, etc ..

tikanga Telecommunications

I teie mahana, rawa i riro te whanaketanga tere o ngā pūnaha whakawhiti kōrero pūkoro, te maha o kaiohauru i roto i te nuinga o nga whenua nui i te maha o kaiohauru whatunga whakaritea. painga i rite ki te roa i roto i te mākete pūkoro mau GSM-900 paerewa / 180, i tae te pūnaha te rohe o tino i roto i te whakamahi o GPRS me Mata hangarau hou. kia tino whaihua kia whakaaro rite te pūnaha kōrero pūkoro ki waehere wehenga o takere CDMA e he tūmataiti ōrite, me te mahi pūngao. I teie mahana, ki te waihanga i tētahi pūnaha kōrero pūkoro 3G i runga ki te paerewa, me MT-2000, whakawhanakehia e te International Telecommunication Union, whakamahia e toru paerewa e hāngai ana i runga i te hangarau CDMA: CDMA ONE, CDMA 2000 ko WCDMA. Hei wāhanga o te paerewa IMT-2000, te mahi i runga i hanganga o amiorangi whaiaro pūnaha kōrero pūkoro Orbocomm, Thuraya, Clobal Star, Iridium. Ahakoa te mahi arumoni o pūnaha kore kua tutuki tika ki nga raruraru o te pūtea o kaupapa me fifi hangarau. Hoki ngā mōhiohio kamupene whatunga te pai kï DECT pūnaha irirangi.

pūnaha tuku tohu nohopuku

Ngā mihi ki mua i roto i te hangarau Microelectronics, hangaia, ka whakamahia pūkoro me te rorohiko-kōtuitui o tenei ra, me te torotoro waea, pērā i Nihokikorangi, ZigBee, WiMAX, WiFi me etahi atu. I roto i mahi, te whakamahi o ngā pūnaha tuku tāwāhi, e kua hanga mā te whakamahi i te mau parau tumu noa me kaupapa o te hanganga, me te rerekē whāurutau awa ki te hono ki nga awa tuku hāngai. kōrero pūnaha kōrero Hydroacoustic i raro i te wai mā te whakamahi i wiri ultrasonic i roto i te kHz 8-20 i te tawhiti o te 4 km. whakamahi pūnaha Taiaho kōrero lasers ki te roangaru o 1-10 microns, ka whakamahia i roto i ngā hononga wāhi. Ryazan mauhaa hanga tipu (Russia) pūrere taiaho transceiver hangaia whakarato i te tohu auau tuku o e pā ana ki 200 Mbit / hekona mo te tawhiti o 2-10 km tikanga whenua, me te whakamahia hei tauira mō te whakawhitihia ngā mōhiohio i waenganui i ngā teihana turanga i roto i ngā pūnaha kōrero pūkoro. pūnaha Communication i roto i huna me te whakamahi raro turuturu (pūihi) taura, hei tauira, umanga EUPEN i te whānuitanga auau 30-1800 MHz. whakapumautia US pūtaiao te taea o te tuku o ngaru irirangi gektametrovogo whānui i roto i te ngakau aroha o te whenua. Kei te whakapono te reira e i roto i te whakanohonga o transponders i te rohe o runga ki te 200 m taea te hanga he hononga kōrero mō te whakawhitihia he tohu ki te whānuitanga o e pā ana ki 500 Hz.
