Background
IWAVE yakazvigadzira yakasanganiswa sisitimu yakavakirwa paLTE tekinoroji, ine mabhenefiti ari pachena mukuvharika kwemugungwa uye kugona kwakanyanya.
TD-LTE yekunze yakasanganiswa sisitimu ine zvakanakira zvehurefu-refu yekuvhara tekinoroji, yakakwirira-simba RRU tekinoroji, Power boosting tekinoroji, nhete yedanda nhepfenyuro kusimudzira kuvharika kwenetiweki, yakakwira-kuhwina CPE, yakaderera-frequency yekutaurirana tekinoroji, nezvimwewo, zvinobudirira kuvandudza kufukidzwa kwemauto-vagari vemubatanidzwa frequency band.Simba.Iine maitiro ekubatanidzwa kwepamusoro uye kuchengetedza-isina, yakakodzera kune yakaoma uye yakaoma mamiriro ezvinhu, uye inopa yakagadzikana uye yakavimbika kutapurirana.
Unyanzvi Zvimiro zveZvigadzirwa
Ultra-refu yekuvhara tekinoroji
Kuburikidza nenguva yakakosha slot configuration, chinhambwe chekuvharira chinogona kusvika 90km kusangana nezvinodiwa zvekutaurirana zvepedyo, zvepakati, uye kure kumakungwa.Iyo inowanzoshandiswa yakakosha subframe configuration 7 (10: 2: 2) inogona kutsigira 15km, uye inowanzo shandiswa yakakosha subframe configuration 5 (3: 9: 2) inogona kutsigira 90km.Yakanyanya kumisikidzwa (kurasikirwa kwechikamu chebandwidth), kumisikidzwa 0, inogona kusvika 119km.
Narrow beam kutepfenyura kunosimudzira kuvharika kwetiweki.
Iyi tekinoroji inogona kudzora chiteshi, PDSCH TM2/TM3, CRS, nezvimwewo, iyo inokodzera mamiriro ane mashoma ekudzika pasi CRS kufukidzwa.Kune yekupedzisira-yakareba nzira yekuvhara uye diki chitsuwa chekuvhara, iyo inotariswa nzvimbo yekuvhara idiki uye inogona kutariswa kushandiswa.Inogona kukwidziridzwa kuCRS kufukidzwa ne50%.
High-inowana CPE
CPE yakaderera ruzha amplifier basa inosimudzira LTE yekugamuchira kuwana.Yakashongedzerwa ne8db omnidirectional antenna, uchiwana ingangoita 20dbi kuwana, Bvisa kukuvadzwa kwekupinda kwe10 ~ 20db, wedzera kuvandudza maitiro ekugamuchira, uye nzvimbo yekuvhara inogona kuwedzerwa ne150% -200%.Chishandiso ichi IP67 haina mvura, inogadzirisa-isina mushure mekuiswa.
Low Frequency Propagation tekinoroji
Iyo 600MHz frequency band inonzi "digital dividend", iyo ine zvakanakira yekuderera kwekutapurirana kwechiratidzo kurasikirwa, kufukidzwa kwakafara, kupinza kwakasimba, mutengo wakaderera wetiweki, nezvimwe. Naizvozvo, inoonekwa seyegoridhe frequency band yekuvandudza kwenharembozha.
Yakaderera frequency ine mamwe mabhenefiti ekuparadzira, yakaderera kutapurirana kurasikirwa, uye yakasimba radiation kugona.Pakuisa akawanda-base zviteshi, mukana wekuvhara uri pachena.Semuyenzaniso, munzvimbo dzemadhorobha dzakakomba, nhamba yezviteshi zvekuendesa inodiwa 1.4GHz/1.8GHz iri 3-4 nguva ye600MHz, uye munzvimbo dzisina chinhu dzakaita semasaubhu kana zvitsuwa, inopetwa 2-3 nhamba yenzvimbo. iyo 600M frequency band.
Kubatanidzwa kwepamusoro, kuchengetedza-pasina
Midziyo yacho yakanyatsobatanidzwa pasina kutumirwa kwekamuri yemuchina, sisitimu inosanganisa akakosha LTE network zvinhu zvakaita seRRU, BBU, EPC nezvimwe zvakadaro, zviri nyore kuendesa, uye zvine zero mumidziyo isina mvura giredhi IPv6.
Iko hakuna kudikanwa kwekutumirwa kwekamuri yekombuta, uye michina yakanyatsobatanidzwa.Iyo sisitimu inosanganisa RRU, BBU, EPC uye mamwe makiyi eLTE network zvinhu mune imwe, iri nyore kutumirwa.Midziyo yacho haina mvura level IPV6, uye hapana chekugadzirisa.
Networking Topology Mepu mukuyedzwa uku
Tsanangudzo pfupi yebvunzo
1, Iyo TD-LTE yekunze yakabatanidzwa sisitimu yakavakirwa pane simbi shongwe kana yakakwirira-inokwira chivakwa padyo nechitsuwa, uye yeruzhinji network isina waya inoshandiswa.
Iyo yeruzhinji network router ndeye TD-LTE yekunze yakasanganiswa sisitimu yekuwedzera, iyo inogona kuiswa, simba, uye kugamuchirwa kubva kune akawanda opareta base zviteshi kuti ive nechokwadi chekudzoka.
2, Iyo TD-LTE yekunze yakasanganiswa sisitimu ine yakanyanya kubatanidzwa uye inobatanidza iyo yakakosha network, BBU neRRU kuve nechokwadi chesimba repamusoro-simba rakakura-nzvimbo yekuvhara uku uchivandudza kugadzikana kwekushanda kwemidziyo.Iyo yakabatanidzwa sisitimu inotsigira IP67 isina mvura uye inochinjika kune yakaoma nharaunda uye yakaipa mamiriro ekunze.
3, Iyo TD-LTE yekunze yekubatanidza sisitimu uye CPE yakafukidzwa nemauto-vanhu fusion frequency band (566-606 frequency point).Iyo yakaderera-frequency nzvimbo nzira yekurasikirwa idiki, uye kutapurirana nekwakasimba diffraction kugona kunovimbisa bandwidth uye yakawedzera yekuvhara kureba.
4, CPE indasitiri-giredhi IP67 haina mvura, inochinjika kune yakaoma yekunze nharaunda, uye maindasitiri-giredhi mhando inovandudza bandwidth uye kugadzikana.Kuendeswa kwakabatana uye kugovera magetsi nemidziyo yemamiriro ekunze.

Midziyo yacho yakamisikidzwa muchivakwa chepamusoro-soro cheDishui Lake muShanghai, iyo inoedza Yangshan Port neHangzhou Bay zvichiteerana.Chiteshi chepasi chinoiswa panguva iyoyo nedanda retatu (33m pamusoro pegungwa), uye kureba kwekuyedza kureba i54km.
CPE chiratidzo chesimba-74, nharembozha (200mw) yakajairika kuwana, yakajairika bhizinesi, yakajeka uye yakatsetseka vhidhiyo.Izvo zvinodikanwa zveprojekiti panguva iyoyo zvakazadzikiswa, uye kumwe kuyedzwa hakuna kuitwa.Inogona kuwana kuenderera kuvharika kwemvura yeYangshan Island uye Drishui Lake.
