• Waraaqdani waxay ka hadlaysaa teknolojiyadda muhiimka ah ee 3G / 4G / 5G (Qarniga saddexaad / Jiilka saddexaad / Jiilka afraad / Jannada shanaad) Nidaamyada isgaarsiinta, ka dibna waxay ka hadlaan kala duwanaanshaha tikniyoolajiyada anteeno ah ee ay qaateen. Kadib akhriska iyo barashada tiro badan oo waraaqo ah oo ku saabsan tikniyoolajiyadda muhiimka ah ee tikniyoolajiyadda 3G / 4G / 5G / 5G, halkan waxaan sameeyaa falanqayn iyo soo koobid aniga. Iyada oo la adeegsanayo horumarinta deg-degga ah ee sayniska iyo tikniyoolajiyadda, tikniyoolajiyadda isgaarsiinta mobilada ayaa maray isbeddelo qoto dheer, laga bilaabo 1G ilaa 2G, ilaa 3G iyo 5G iyo 5G. Bishii Disembar 4, 2013, jiilka afraad ee wada xiriirka mobilada ee 4G tikniyoolajiyadda ayaa si rasmi ah looga shaqeeyey suuqa Shiinaha, taasoo micnaheedu yahay in warshadaha isgaarsiinta guur-guura ee Shiinaha ay soo galeen 4G xilligii. Waqtigaan, machadyada cilmi baarista ee dalal kala duwan iyo shirkado caan ah oo caan ah ayaa ku hawlanaa cilmi baarista tikniyoolajiyada isgaarsiinta ayaa gashay cilmi-baarista iyo horumarka jiilka cusub ee isgaarsiinta mobilada, oo ah 5G (jiil) nidaamka isgaarsiinta mobilada mobilada moobiilka). Si kasta oo jiil kasta oo nidaamka isgaarsiinta, tikniyoolajiyadda cilmi baarista ayaa ah in la falanqeeyo astaamaha kanaalka isgaarsiinta wireless-ka si looga gudbo faragalinta buuqa. Baarayaal badan ayaa hadda eegaya tikniyoolajiyadda MIMO ee MIMO. Sidee uga duwan yahay tikniyoolajiyadda anteeno ee loo adeegsado nidaamyada 3G / 4G / 4G? Miyay noqon doontaa tikniyoolajiyadda aasaasiga ah ee jiilka xiga ee isgaarsiinta wireless? 1 Teknolojiyada Muhiimka ah ee Nidaamka Isgaarsiinta ee 3G / 4G / 5G / 5G Bishii Janaayo 2009, tikniyoolajiyadda wargaariska ee Shiinaha iyo tikniyoolajiyadda macluumaadka Shiinaha ee loo soo saaray Shiinaha Mobile, Shiinaha iyo Shiinaha Unicom, oo muujinaya in Cunnio ay galeen xilliga isgaarsiinta 3G. Jiilka saddexaad ee nidaamka isgaarsiinta mobilada badanaa waxaa ka mid ah WCDMMA, CD-MA2000 iyo Td-SCDMA. Teknolojiyadda ugu muhiimsan waxaa ka mid ah: A. Rakish helitaanka teknolojiyadda; B. Kalluunka kanaalka iyo fulinta tikniyoolajiyadda; C. Teknolojiyadda xakameynta awoodda; D. Tukshahooyinka ogaanshaha badan ee loo yaqaan 'Isticmaalaha'. E. Antenna Smartenna; F. Raadiyaha Software-ka. 1 4G Nidaamka isgaarsiinta ee mobilada, ee 'ofdm' ee tikniyoolajiyada tikniyoolajiyadda soo noqnoqda) ee tikniyoolajiyada) ayaa la qaatay). Tiknolojiyadda ofDM waxaa sabab u ah adeegsiga muuqaalka ah

  Waxaa si weyn loogu tixgeliyaa inay tahay heer sare oo ah 2 iyo 2 iyo kahortagga kahortaga badan ee kahortaga badan. Mustaqbalka, cilmi baarista la xidhiidha tikniyoolajiyada ADDM waxaa sidoo kale lagu fulin doonaa 5G shabakadaha isgaarsiinta. Teknolojiyadda ugu muhiimsan ee nidaamka isgaarsiinta ee 4G waxaa ka mid ah: a. Tikniyoolajiyadda ofDM; B. Mimo teknolojiyadda; O. D. Raadiyaha software; E. Teknolojiyadda Antenna Smart anenna; F. IPV6 Teknolojiyadda. Wasaaradda warshadaha ee Shiinaha iyo tikniyoolajiyadda macluumaadka Shiinaha ayaa hadda soo saartay 4G shati shati saddex shirkado waaweyn, oo wali waxay u diraan shabakadooda si ballaaran oo leh tiro yar oo isticmaaleyaal ah. Waqtigaan, Mobilada Shiinaha ayaa sheegay inay bilaabi doonto cilmi baarista iyo horumarinta nidaamka isgaarsiinta ee 5G. Falanqeeyayaasha ayaa tilmaamay in saddexda hawl-wadeyaal waaweyni ay ka qeyb qaataan cilmi-baarista iyo horumarka 5G, mid waa inuu la sii wado isbedelada waqtiyada, kan kalena waa in baahida ay ka dhaqso badan tahay horumarka teknolojiyadda. Li Zhengmae, oo ah kuxigeenka Madaxweynaha Shiinaha Mobile, ayaa sheegay in 2014 MWC ee 2014 ee Barcelona: "Mobilada Shiinaha ayaa si buuxda u taageeri doonta horumarinta mashruucyada 5G, iyagoo rajeynaya inay hogaamiyaan warshadaha 5G tikniyoolajiyadda farsamada iyo dejinta heerarka farsamada." Iyadoo qoto dheer ee cilmi baarista tikniyoolajiyadda isgaarsiinta moctor-ga, tikniyoolajiyadda aasaasiga ah ee taageerada 5G ayaa si tartiib tartiib ah loo qeexi doonaa oo lagu gali doonaa heerka cilmi baarista la taaban karo iyo heerka samaynta sannadaha soo socda. Xeerbeegtida ayaa wali ka maqan tirooyin muhiim ah oo loo adeegsan doono mustaqbalka. Si kastaba ha noqotee, waxaan soo diyaariyay liis ka kooban sagaal tikniyoolajib oo muhiim ah oo diiradda lagu saaray doodda gole-ka-guur sare ee ugu sarreeya. A. Teknolojiyadda MIMO ee miisaanka ah; B. Shaandhaynta shaashadda iyo tikniyoolajiyada side-side-side C. Tiknoolajiyada Duplex oo buuxa; D. Tikniyoolajiyadda shabakadda 'ultra-cuterogenenoous'; E. Tilmaaceynta Shabakadda Shabakadda ee Abaabulka; F. Adeegsiga guutada soo noqnoqda ee sare; G. Shabakadaha bilaa-galka lagu qeexay H. Teknolojiyadda Helitaanka Wireless-ka: (1) BDMA (BDMA waxay kala tagtaa tikniyoolajiyad helitaan badan)

Waxaan baranayaa tikniyoolajiyada MIMO ee shaybaarkayga. Jaantus 1 wuxuu muujiyaa dadka isticmaala oo istaagaya midba midka kale oo ku saleysan anteeno ballaaran. Waxqabadka nidaamyada isgaarsiinta wireless-ka waxaa inta badan lagu xadiday wadooyinka wireless-ka mobilada. Kanaalada wireless-ka waa mid aad u adag, oo moodelkeeda had iyo jeer waxay ahayd meel adag oo ku saabsan qaabeynta nidaamka. Guud ahaan, tirakoobka waxaa loo sameeyaa iyadoo loo eegayo qiimayaasha lagu cabiray ee nidaamyada isgaarsiinta ee xargaha soo noqnoqda ee gaarka ah. Kanaalada foosha ee wireless-ka ah ayaa loo qaybiyaa noocyo waaweyn oo ka-xirta khamaarka ka soodaynta iyo tusaalaha yar ee ka-hortagga yar ee ka dhexeysa. Waxa loogu yeero qaab-dhismeedka ballaaran ee loo yaqaan 'Foles-ka' saamayn. Moodeel yar oo cabir yar oo cabir ah ayaa qeexaya isbeddelada deg-degga ah ee xoojinta garoonka ee masaafo gaaban ama waqti. Moodeelka ballaaran ee ka soo baxa ee ka soo baxa ayaa sababay saameynta dusha sare ee dusha sare (sida buuraha, kaymaha, dhismayaasha, iwm.) Inta u dhaxaysa qaataha iyo isha. Qaabka ugu yar ee ka soo baxa ee ka soo baxa ee ka soo baxa ee ay sababaan saameynta isku-dhafka ah iyo saameynta Dopler. Haddii ay jiraan tiro badan oo jidad ah oo muujinaya laakiin aan lahayn Los (seenyaalaha tooska ah), cabir yar ayaa loo yaqaan 'rayleigh', iyo baqshad seenyaalaha ah ee la soo saaray si rasmi ah oo ay tiradooda tirakoobka. Haddii Los uu jiro, baqshadda ayaa ku qasbanaysa qaybinta daji. Ifafaale-ka-soo-dhafka ah ee 'Compenomeath' ayaa sababaya firidhsan oo soo noqnoqda iyo soo noqnoqda xulashada.
