Kunyangwe 4G yakaiswa rezinesi kuChina, iyo yakakura-chiyero network network yekuvaka ichangotanga. Kutarisana nekuputika kwekukura kwe data nhare, zvinodikanwa kuti uenderere mberi nekuvandudza network kugona uye network kuvaka. Nekudaro, kupararira kwe 4G frequency, kuwedzera kwekukanganisa, uye kudiwa kwekugovera saiti ne 2G zvidhori zvekushanduka kwechiteshi chekubatana, bandwidth uye kuwedzera kugadziriswa.
4G network yekuvhara kugona.
Iyo yakanaka network yekuvharirwa layer uye imwe gobvu yehuwandu hwekuisa midziyo miviri yekuziva iyo network network.
Njiva nyowani yenyika netiweki inofanirwa kufunga nezvekuvakwa kwe network yekugona kwe network yakazadza iyo kufukidzwa chinangwa. "Kazhinji, pane nzira nhatu chete dzekuvandudza network kugona," wang
Imwe ndeye kushandisa yakawanda nguva dzekuita kuti uite bandwidth uder. Semuenzaniso, GSM pakutanga yaingova ne 900mhz frequency. Gare gare, vashandisi vakawedzera uye 1800mhz frequency yakawedzerwa. Zvino 3G uye 4G Frequency more. China Mobile's TD-LTE Frequency ine mapoka matatu, uye kuwanda kwe2,6GHz yashandiswa. Vamwe vanhu vari muindasitiri vanotenda kuti iyi ndiyo muganho, nekuti kukwidziridzwa kwakanyanya-huwandu kuchave kwakanyanya uye kuiswa uye kubudiswa kwemidziyo. Iyo yechipiri ndeyekuwedzera huwandu hwezviteshi zvigadziko, izvo zvakare zvakanyanyisa kushandiswa nzira. Parizvino, dentity yezvikamu zvigadziko mumatanho makuru uye epakati-svikiro yakaderedzwa kubva paavhareji yechiteshi chimwe chete pachigadzirwa chimwe chete chemakumi maviri emamita. Yechitatu ndeyekuvandudza mashandiro ehunyanzvi, ndeipi nzira yechizvarwa chose cheboka rekutaurirana kwenyanzvi. Parizvino, iyo spectrum inoshanda ye 4G ndiyo yepamusoro, uye yasvika iyo yekudzikira pasi pe100m muShanghai.
Kuve neakanaka network yekuvhara uye imwe gobvu yehuwandu hwekugona miviri yakakosha nheyo mbiri dzakakosha dzetwork. Zviripachena, China Mobile Mobilemise yeTD-LTE ndeyekugadzira yakakwirira-mhando network network uye kumira kumusoro kwe 4g musika une ruzivo rwemushandisi. "Isu tinobatanidzwa mukuvakwa kwevazhinji veiyo 240 tete network munyika." "Kubva pane zvakaitika kuna Commscipe, pane zvinhu zvishanu muLTE Network kuvaka basa rakanaka mukudzokerazve, ndiko kuti, iro bandwidth yeiyo uplink sign uye pasi sign nzvimbo
Nhoroondo dzehunyanzvi dzeRour Management bvunzo.
Iri idambudziko chairo rekutarisira ruzha revo uye ita kuti vatambi vepepeti vane simba rakanyanya-kumhanya.
Yakasiyana ne3G chiratidzo chekuvandudza nekuwedzera simba rekutapurirana, 4G network ichaunza ruzha rutsva nekuwedzera chiratidzo. "Hunhu hwe 4G network ndewekuti ruzha harubatsiri chikamu chakafukidzwa neAntenna, asi zvine chekuita neyakaipisisa maoko ekurasa." Kuita ndiko kuti Data rekutapurudzira data rakaderedzwa, ruzivo rwemushandisi rwadzikiswa, uye mari yacho yakaderera. " Wang sheng akati, "Iyo inther network ine mwero kubva pachigadziko, iyo yakaderera iyo data yedata, uye kuswededza network kune iyo transmitter, vamwe vanoshandisa zviwanikwa vanogona kuwana. Isu tinofanirwa kubata ruzha rwokuita ruzha, saka kuti iyo yemupendero wetiweki inogona kuwana yakakwira-kumhanya kuwana, ndechipi dambudziko ratinonyatsoda kugadzirisa. " Kugadzirisa dambudziko iri, kune zvinodikanwa zvakati: Kutanga, bhasikoro reRF chikamu chinofanira kunge chakakura zvakakwana; Chechipiri, mashandiro emidziyo yeiyo radio radio thawebhuroka inofanirwa kuve yakanaka zvakakwana; Yetatu, iyo bandwidth yeiyo yekukwira chiratidzo yakadzoserwa inofanira kunge yakafara zvakakwana.
Muchinyakare ka2G network, iyo network yekuvhara yakadururwa neyakajairika base station masero akakura. Nhare mbozha dzinogona kugamuchira masaini kubva kune dzakasiyana zviwi zvidiki. 2G mbozha mafoni anokiya nechiteshi chesimba nechiratidzo chakasimba, kuregeredza vamwe. Nekuti hazvishandure kazhinji, hazvizokonzere kupindira kuchitokisi chinotevera. Naizvozvo, muGSM network, kune 9 kusvika ku12 nzvimbo dzinofukidza nzvimbo dzinogona kutenderwa. Nekudaro, munguva yechitatu, kufukidzwa kwakawandisa kwetiweki kuchave nekukanganiswa kwakanyanya pakugadzirisa maitiro ehurongwa. Zvino, iyo antenna ine 65 degree rakakomberedza hafu nehafu inoshandiswa kune matatu sekadhi yekuvhara. Iyo nhatu dzepasi pekufukidzwa kweLTE inoda yakakwirira-performance antenna kuti iitwe nenzira imwechete ne3G. "Anonzi anonzi High-performance Antenna zvinoreva kuti kana kuita 65 degree inodonha zvakanyanya "ZVINOKOSHA ZVINODIWA ZVESE ZVESE." Wang Sheng akadaro.
Frequency Docioned yakazvimirira legetrically tunable antenna iri kuwedzera uye zvakanyanya kukosha.
Izvo zvinodikanwa kudzora mupendero weNetwork waveform nenzira kwayo kuti uderedze intern station kupindira. Nzira yakanakisa ndeyekuziva zviri kure antenna kudzora.
Kugadzirisa kudzora kwekuvhiringidza kwe network, kunyanya zvinoenderana nezvikamu zvinoverengeka: chekutanga, network kuronga, kusiya maratidziro akakwana mu frequency; Chechipiri, chishandiso chikamu, maitiro ega ega anofanirwa kudzorwa zvakanaka; Yetatu, kuisirwa chikamu. "Isu takapinda muChina muna 1997 ndokuita nyaya dzakawanda dzekushandisa Gadzira vanobatana uye antennas. "Wireless zvigadzirwa, kunyanya zvigadzirwa zvekunze, zvine nzvimbo yakaipisisa mune yese yekukurukurirana. "Zvigadzirwa zvedu zvinogona kumira ipapo kwemakore gumi kusvika makumi matatu. Hazvisi nyore." Wang Sheng akadaro.
