I-5G isizukulwane sesi-5 sobuchwepheshe obungenawaya.Abasebenzisi bazoyazi njengobunye bobuchwepheshe obushesha kakhulu, obuqine kakhulu owake wabonwa umhlaba.Lokho kusho ukulandwa okusheshayo, ukunensa okuphansi kakhulu, kanye nomthelela omkhulu endleleni esiphila ngayo, esisebenza ngayo, nesidlala ngayo.
Nokho, ekujuleni komhlaba, kunezitimela ezihamba ngaphansi komhlaba emhubheni.Ukubuka amavidiyo amafushane ocingweni lwakho kuyindlela enhle yokuthatha ikhefu esitimeleni esingaphansi komhlaba.Ngabe i-5G ivala futhi isebenza kanjani ngaphansi komhlaba?
Ngokusekelwe ezidingweni ezifanayo, ukumbozwa kwe-5G metro kuyinkinga ebalulekile kubaqhubi beTelecommunication.
Ngakho-ke, i-5G isebenza kanjani ngaphansi komhlaba?
Isiteshi se-Metro silingana nesitezi esingaphansi esinezitezi eziningi, futhi singaxazululwa kalula ngezixazululo zendabuko ze-In-building noma amasistimu amasha asebenzayo e-antenna Asakazwa ngama-opharetha.Umsebenzisi ngamunye unohlelo olukhule kakhulu.Okuwukuphela kwento ukuphakela njengoba yakhelwe.
Ngakho-ke, umhubhe omude wesitimela esihamba ngaphansi komhlaba yiwo okugxilwe kuwo ekumbozweni kwesitimela esingaphansi komhlaba.
Imigudu ye-Metro ivamise ukuba ngaphezu kwamamitha ayi-1,000, ihambisana nemincane namajika.Uma usebenzisa i-antenna eqondisayo, i-engeli yokuklama isignali incane, ukuncishiswa kuzoba ngokushesha, futhi kulula ukuvinjwa.
Ukuze kuxazululwe lezi zinkinga, amasignali angenawaya adinga ukukhululwa ngokufanayo aqonde emhubheni ukuze akhe isignali ewumugqa, ehluke kakhulu ekumbozweni kwezingxenye ezintathu zesiteshi esikhulu esingaphansi.Lokhu kudinga uthi olukhethekile: ikhebula elivuzayo.
Ngokuvamile, izintambo zerediyo-frequency, ezaziwa ngokuthi iziphakeli, zivumela isignali ukuthi ihambe ngaphakathi kwentambo evaliwe, hhayi nje kuphela ayikwazi ukuvuza isignali, kodwa ukulahlekelwa kokudlulisela kungaba kuncane ngangokunokwenzeka.Ukuze isignali ihanjiswe kahle isuka kuyunithi ekude iye othini, khona-ke amaza omsakazo angasakazwa kahle ngothi.
Ngakolunye uhlangothi, ikhebula elivuzayo lihlukile.Ikhebula elivuzayo alivikelwe ngokugcwele.Ine-slot yokuvuza esatshalaliswe ngokufanayo, okungukuthi, ikhebula elivuzayo njengochungechunge lwezikhala ezincane, ivumela isignali ukuthi iphume ngokulinganayo ngezikhala.
Uma umakhalekhukhwini usuwatholile amasignali, amasignali angathunyelwa ngezikhala aye ngaphakathi kwekhebula bese edluliselwa e-Base Station.Lokhu kuvumela ukuxhumana okubili, okwenzelwe izimo ezilandelanayo ezifana namahubhu we-metro, okufana nokuphendula amalambu okukhanya endabuko abe amashubhu amade e-fluorescent.
Ukumbozwa komhubhe we-Metro kungaxazululwa ngezintambo ezivuzayo, kodwa kunezinkinga ezidinga ukuxazululwa ngama-opharetha.
Ukusiza abasebenzisi babo abafanele, bonke opharetha badinga ukwenza isignali ye-metro.Uma kubhekwa indawo elinganiselwe yomhubhe, uma u-opharetha ngamunye akha isethi yezinto zokusebenza, kungaba izinsiza zokumosha futhi kube nzima.Ngakho-ke kuyadingeka ukwabelana ngezintambo ezivuzayo futhi usebenzise idivayisi ehlanganisa ama-spectrum ahlukene avela kuma-opharetha ahlukene futhi iwathumele kukhebuli evuzayo.
Idivayisi, ehlanganisa amasignali nama-spectrum avela ku-opharetha abahlukene, ibizwa nge-Point of Interface (POI) Combiner.Izihlanganisi zinezinzuzo zokuhlanganisa amasignali amaningi kanye nokulahlekelwa okuphansi kokufaka.Kusebenza ohlelweni lokuxhumana.
Esithombeni esilandelayo sikhombisa, isihlanganisi se-POI sinezimbobo ezimbalwa.Ingakwazi ukuhlanganisa kalula i-900MHz, 1800MHz, 2100MHz, kanye ne-2600MHz namanye amafrikhwensi.
Kusukela ku-3G, i-MIMO yangena esigabeni sezokuxhumana ngeselula, yaba izindlela ezibaluleke kakhulu zokwandisa umthamo wesistimu;nge-4G, i-2 * 2MIMO isibe yindinganiso, i-4 * 4MIMO iyizinga eliphezulu;kuze kube yinkathi ye-5G, i-4*4 MIMO isibe yindinganiso, iningi lamaselula lingasekela.
Ngakho-ke, ukumbozwa komhubhe kamasipala kufanele kusekele okungu-4*4MIMO.Ngenxa yokuthi isiteshi ngasinye sohlelo lwe-MIMO sidinga i-antenna ezimele, ukumbozwa komhubhe kudinga amakhebuli amane avuzayo ahambisanayo ukuze kufinyelelwe ku-4*4MIMO.
Njengoba isithombe esilandelayo sibonisa: Iyunithi eyi-5G eyihlane njengomthombo wesignali, ikhipha amasignali angu-4, ukuwahlanganisa namasignali abanye opharetha ngesihlanganisi se-POI, futhi iwaphakele kuzintambo ezi-4 ezivuzayo ezifanayo, ifinyelela ukuxhumana okukabili kwamashaneli amaningi. .lena indlela eqondile nephumelelayo yokwandisa umthamo wesistimu.
Ngenxa yesivinini esikhulu somzila ohamba ngaphansi komhlaba, ngisho nokuvuza kwekhebula ukuvala isiqephu emugqeni, omakhalekhukhwini bazoshintshwa njalo futhi baphinde bakhethwe lapho kuhlangana khona isiqephu.
Ukuze kuxazululwe le nkinga, ingahlanganisa imiphakathi eminingana ibe umphakathi omkhulu, ngokunengqondo ingeyomphakathi owodwa, ngaleyo ndlela inwebe izikhathi eziningana zokutholakala komphakathi owodwa.Ungagwema ukushintsha nokukhetha kabusha izikhathi eziningi kakhulu, kodwa umthamo nawo uyancishiswa, ulungele izindawo eziphansi zokuxhumana.
Ngenxa yokuvela kokuxhumana kweselula, singajabulela isignali yeselula noma nini, noma kuphi, ngisho nangaphansi komhlaba.
Ngokuzayo, yonke into izoguqulwa yi-5G.Ijubane lokushintsha kwezobuchwepheshe emashumini eminyaka adlule liye lashesha.Okuwukuphela kwento esiyazi ngokuqinisekile ukuthi, ngokuzayo, izoshesha nakakhulu.Sizothola ushintsho kwezobuchwepheshe oluzoguqula abantu, amabhizinisi, kanye nomphakathi wonkana.
