• Incazelo ye-3G 4G LTE / 5G Antenna
• Isiteshi sesisekelo se-2G: GSM: 900 / 1800mhz; I-CDMA: 800 MHZ;
  
  I-3G Base Station: CDMA2000 & WCDMA: 2100mhz; I-TD-SCDMA: 1880-1920201 0 0-20220232-2370 MHZ;
  
  I-4G Base Station: TDD-LTE: 2320-2370,2570-2620MHz;
• Leli phepha lixoxa ngobuchwepheshe obubalulekile ku-3G / 4G / 5G (Isizukulwane sesithathu / Isizukulwane Sesine / Isizukulwane Sesihlanu), bese sidingida umehluko kubuchwepheshe be-Antenna. Ngemuva kokufunda nokutadisha inani elikhulu lamaphepha kubuchwepheshe obubalulekile bohlelo lokuxhumana lwe-3G / 4G / 5G, lapha ngenza ukuhlaziya okuthile nokufingqa okwami. Ngokuthuthuka okusheshayo kwesayensi nobuchwepheshe, ubuchwepheshe bokuxhumana ngeselula buye bashintshana kakhulu, kusuka ku-1g kuya ku-2g, kuya ku-3g, bese kuya ku-4g no-5g. NgoDisemba 4, 2013, isizukulwane sesine sobuchwepheshe bezokuxhumana kwe-4G ubuchwepheshe obenziwa ngokusemthethweni emakethe yaseChina, okusho ukuthi leyo mbombo yezokuxhumana yaseChina yaseChina ingene kule nkathi ye-4G. Ngalesi sikhathi, izikhungo zocwaningo emazweni ahlukahlukene namabhizinisi adume umhlaba wonke ahlanganyele ocwaningweni lwezobuchwepheshe lwezokuxhumana angenele ocwaningweni nasekuthuthukisweni kwesizukulwane esisha sezokuxhumana ngeselula, okungukuthi 5G (Isizukulwane sesizukulwane sesihlanu). Akunandaba noma yisiphi isizukulwane sohlelo lokuxhumana, ubuchwepheshe bocwaningo ukuhlaziya izici zesiteshi sokuxhumana okungenantambo ukunqoba ukuphazanyiswa komsindo. Abacwaningi abaningi manje sebebheka ubuchwepheshe obukhulu be-MIMO. Kwehluke kanjani kubuchwepheshe be-antenna obusetshenziswa ezinhlelweni zokuxhumana ze-3G / 4G? Ngabe kuzoba ubuchwepheshe obusemqoka besizukulwane esilandelayo sokuxhumana okungenantambo? I-1 Technologies Key of 3g / 4G / 5G Ukuxhumana System 1.1 Ama-Technologies aphambili ohlelo lokuxhumana lwe-3G kusukela ekuqaleni kweminyaka yama-199, i-Mobile Communication Industry yaqala ukutadisha izindinganiso nobuchwepheshe besizukulwane sesithathu sokuxhumana ngeselula. NgoJanuwari 2009, inkonzo yasemkhakheni yaseChina kanye nobuchwepheshe bolwazi ikhiphe amalayisense angama-3G eChina Mobile, eChina Telecom naseChina Unicom, okukhombisa ukuthi iChina yangena enkathini yezokuxhumana ngeselula le-3G. Isizukulwane sesithathu sokuxhumana mobile mobile ikakhulukazi sifaka i-WCDMA, CD-Ma2000 ne-TD-SCDMA. Ubuchwepheshe bayo obuhle bufaka: A. I-Race Recorm Technology; B. Amakhodi we-Channel Cannel ne-Decoding Technology; C. Ubuchwepheshe bokulawula amandla; D. Ubuchwepheshe bokutholwa komsebenzisi abaningi; E. smart antenna; F. I-Software Radio. 1.2 Ubuchwepheshe obukhulu bohlelo lokuxhumana lwe-4G ngoDisemba 2013, iChina yangena ngokusemthethweni inkathi ye-4G (isizukulwane sesizukulwane sesizukulwane seselula). Ku-4G Mobile Communication System, ye-OFTM (i-Orthogonal Frequency Division MultenCHINGXING) YENZIWA. Ubuchwepheshe be-OFDM kungenxa yokusetshenziswa kwayo kokubukwa

  Iminyaka eyi-14 igxile ocwaningweni lwe-antenna kanye nentuthuko, ukukhiqizwa, ukuthengisa, ama-30,000 amandla efektri, umthamo wokukhiqiza abantu abangama-600, i-antenna enkulu ye-sucker, i-fiber fiber aqinisiwe,
  
  Kubhekwa kabanzi njengezinga eliphakeme lokusebenza okungu-2 nokuhle kokulwa nokuwohloka. Esikhathini esizayo, ucwaningo oluhlobene no-Ofdm Technology luzokwenziwa futhi kumanethiwekhi wokuxhumana we-5G. Ubuchwepheshe obukhulu bohlelo lwe-4G lokuxhumana lubandakanya: a. Ubuchwepheshe be-OFDM; B. Mimo Technology; C. Ubuchwepheshe bokutholwa komsebenzisi abaningi; D. Umsakazo wesoftware; E. Ubuchwepheshe be-Smart Antenna; F. IPv6 Technology. Inkonzo yasezimboni yaseChina neChina vele ikhiphe amalayisense we-4G kubahlinzeki abathathu abakhulu, futhi basathumela amanethiwekhi abo ngezinga elikhulu labasebenzisi abancane. Ngalesi sikhathi, iChina Mobile ithe izoqala ucwaningo kanye nokuthuthukiswa kohlelo lokuxhumana lwe-5G. Abahlaziyi baveza ukuthi abasebenza emikhulu abathathu babamba iqhaza ocwaningweni nasekuthuthukisweni kwe-5G, eyodwa ukuhambisana nezinguquko zezikhathi, kanti enye ukuthi isidingo sishesha ukwedlula ukuthuthukiswa kobuchwepheshe. U-Li zhengmao, owayeyiphini likaMongameli waseChina Mobile, uthe ngo-2014 MWC eBarcelona: "I-China Mobile izokweseka ngokuphelele ukuthuthukiswa kwamaphrojekthi we-5G, ngethemba lokuhola imboni ekuthuthukisweni kobuchwepheshe be-5G kanye nokusethwa kwezindinganiso zobuchwepheshe." Ngokujula kocwaningo lwezobuchwepheshe bezokuxhumana lweselula, ubuchwepheshe bokusekelwa ababalulekile be-5G buzochazwa kancane kancane bese ufaka ucwaningo olujwayelekile lokucwaninga kanye nesigaba seminyaka elandelayo. I-jury isasezimweni ezizosetshenziswa yiphi ubuchwepheshe obuyinhloko ngokuzayo. Kodwa-ke, ngihlanganise uhlu lobuchwepheshe obuyisishiyagalolunye obulokhu kugxilwe kakhulu ezingxoxweni ezinhlanganweni ezihlukene zeselula eziphezulu. A. Ubuchwepheshe obukhulu be-MIMO; B. Ukuhlunga kwebhange elisuselwa ebhange elisezingeni eliphakeme; C. I-DUPLENG CUCEENT CEAT; D. Ubuchwepheshe benethiwekhi obukhulu be-heterogeneous; E. Ukuzihlelela ubuchwepheshe benethiwekhi; F. Ukusetshenziswa kwebhendi yemvamisa ephezulu; G. Kuchazwa amanethiwekhi angenantambo wesoftware; H. Ubuchwepheshe obungenantambo be-wireless: (1) I-BDMA (ugongolo luhlukanisa ubuchwepheshe bokufinyelela okuningi)

  I-3 (2) noma ubuchwepheshe bokufinyelela obungelona o-orthogonal) i. I-D2D (idivaysi-to-device) ukuxhumana. Umdwebo 1 yisakhiwo sama-antennas amakhulu eMimo kumanethiwekhi wokuxhumana we-5G. Ngifunda ubuchwepheshe obukhulu be-Mimo ngelebhu yami. Umdwebo o-1 ukhombisa abasebenzisi abaxhumana nomunye abagxile ku-antenna abasezingeni eliphakeme. Ukusebenza kwezinhlelo zokuxhumana okungenantambo kuvinjelwe ikakhulukazi yiziteshi ezingenantambo ze-wireless. Isiteshi esingenantambo siyinkimbinkimbi kakhulu, futhi ukumodelwa kwalo bekulokhu kuyiphuzu elinzima ekwakhiweni kwesistimu. Ngokuvamile, izibalo zenziwa ngokuya ngamanani alinganisiwe wezinhlelo zokuxhumana kumabhande athile ajwayelekile. Isiteshi esingenantambo se-wireless sihlukaniswe ngemodeli yesiteshi esikhulu esilinganiselwe kanye nemodeli yesiteshi esincane sokufa. Imodeli ebizwa ngokuthi yi-Great-Scale FADIGE ichaza ukuguquguquka kokuqina kwensimu ngaphezulu kwebanga elide (amakhulukhulu noma izinkulungwane zamamitha) phakathi kokudlulisela kanye nokwamukelayo, futhi kukhombisa umthetho wokuthi amandla wesiginali atholakele ngebanga elibangelwa ukulahleka kwendlela kanye nesithunzi umphumela. Imodeli encane yokufakelwa kwesikali ichaza ukuguquguquka okusheshayo kokuqina kwensimu okutholakele ngaphezulu kwebanga elifushane noma isikhathi. Imodeli yesiteshi esikhulu esilinganiselwe ibangelwa yithonya le-contour engaphezulu (njengezintaba, amahlathi, izakhiwo, njll.) Phakathi komukeli kanye nomthombo. Imodeli yesiteshi esincane esilinganiselwe ibangelwa umphumela we-Multipath nomphumela we-doppler. Uma kunenombolo enkulu yezindlela ezibonisiwe kodwa akukho los (Direct Signal) isakhi sesiginali, ukufiphala okuncane kubizwa ngokuthi iRayleigh affing, kanye nemvilophu yesiginali etholakele ichazwa ngokomsebenzi ngokusebenza kwe-rayleigh. Uma i-Los ikhona, imvilophu ingaphansi kokusatshalaliswa kukaRician. I-Multipafuth Effect Penomena ibangela ukufutheka okufuywayo kanye nokukhetha imvamisa
