Keeb kwm
IWAVE nws tus kheej tsim ib qho kev sib koom ua ke raws li LTE thev naus laus zis, uas muaj txiaj ntsig zoo hauv kev pabcuam hauv hiav txwv thiab kev ua tau zoo.
TD-LTE sab nraum zoov integrated system muaj qhov zoo ntawm ultra-ntev kev pab cuam technology, high-power RRU technology, Fais fab boosting technology, nqaim beam broadcasting los txhim kho network kev pab them nqi, high-tau CPE, low-frequency kev sib txuas lus technology, thiab lwm yam, zoo txhim kho. qhov kev pab cuam ntawm cov tub rog-civilian integration zaus band.quab yuam.Nws muaj cov yam ntxwv ntawm kev sib koom ua ke siab thiab kev saib xyuas-dawb, haum rau qhov nyuaj thiab hnyav ib puag ncig, thiab muab kev ruaj khov thiab txhim khu kev qha.
Technical nta ntawm cov khoom
Ultra-ntev kev pab cuam technology
Los ntawm lub sijhawm tshwj xeeb qhov teeb tsa, qhov kev pab cuam nyob deb tuaj yeem ncav cuag 90km kom tau raws li kev xav tau ntawm kev sib txuas lus ntawm ze, nruab nrab, thiab nyob deb seas.Feem ntau siv tshwj xeeb subframe configuration 7 (10:2:2) tuaj yeem txhawb nqa 15km, thiab feem ntau siv tshwj xeeb subframe configuration 5 (3:9:2) tuaj yeem txhawb 90km.Kev teeb tsa hnyav heev (poob ib feem ntawm bandwidth), kev teeb tsa 0, tuaj yeem ncav cuag 119km.
Nqaim beam broadcasting txhim khu kev tiv thaiv network.
Cov thev naus laus zis no tuaj yeem tswj cov channel, PDSCH TM2 / TM3, CRS, thiab lwm yam, uas tsim nyog rau cov xwm txheej uas muaj kev txwv qis qis CRS.Rau cov kev pab cuam ntev-ntev thiab cov kob me me, lub hom phiaj kev pab them nqi yog me me thiab tuaj yeem txiav txim siab siv.Nws tuaj yeem hloov kho mus rau CRS kev pab them nqi li ntawm 50%.
High-tau txais CPE
CPE tsis tshua muaj suab nrov amplifier muaj nuj nqi txhim kho LTE txais tos txais.Nruab nrog 8db omnidirectional kav hlau txais xov, thaum tau txais ze li ntawm 20dbi nce, Tshem tawm qhov kev puas tsuaj ntawm 10 ~ 20db, ntxiv txhim kho qhov kev txais tos, thiab qhov kev pab cuam yuav nce 150% -200%.Cov cuab yeej yog IP67 tsis muaj dej tsis muaj kev saib xyuas tom qab kev teeb tsa.
Tsawg zaus Propagation technology
Lub 600MHz zaus band yog hu ua "digital dividend", uas muaj qhov zoo ntawm cov teeb liab tsis tshua muaj kev sib kis, kev dav dav, kev nkag mus tau zoo, tsis tshua muaj nqi sib txuas, thiab lwm yam. Yog li ntawd, nws tau suav tias yog lub suab nrov golden rau kev txhim kho kev sib txuas lus ntawm tes.
Tsawg zaus muaj ntau qhov zoo tshaj tawm, tsis tshua muaj kev sib kis, thiab muaj zog hluav taws xob muaj peev xwm.Thaum siv ntau qhov chaw nres tsheb, qhov kev pab them nqi kho mob yog pom tseeb.Piv txwv li, hauv cov chaw nroog ntev, tus naj npawb ntawm cov chaw xa khoom siv yuav tsum tau rau 1.4GHz / 1.8GHz yog 3-4 zaug ntawm 600MHz, thiab Islands tuaj, nws yog 2-3 zaug tus naj npawb ntawm cov khoom siv hauv 600M zaus band.
Kev sib koom ua ke siab, tsis muaj kev saib xyuas
Cov cuab yeej siv tau zoo heev yam tsis muaj chav tshuab xa mus, lub kaw lus sib txuas cov ntsiab lus tseem ceeb LTE network xws li RRU, BBU, EPC thiab lwm yam, yooj yim rau kev xa tawm, thiab yog qhov pib xoom hauv cov khoom siv tsis muaj dej tsis zoo IPv6.
Tsis muaj qhov xav tau rau chav siv computer xa mus, thiab cov cuab yeej siv tau zoo heev.Lub kaw lus ua ke RRU, BBU, EPC thiab lwm yam tseem ceeb LTE network ntsiab rau hauv ib qho, uas yooj yim rau kev xa tawm.Cov khoom siv yog qib dej tsis muaj dej IPV6, thiab tsis muaj kev saib xyuas.
Networking Topology Map hauv qhov kev sim no
Cov lus piav qhia luv luv ntawm kev sim
1, Lub TD-LTE sab nraum zoov kev sib xyaw ua ke yog tsim rau ntawm ib lub tsev hlau lossis lub tsev siab siab nyob ze ntawm cov kob, thiab siv cov pej xeem network wireless.
Cov pej xeem network router yog TD-LTE sab nraum zoov kev sib koom ua ke cov khoom siv, uas tuaj yeem ntsia tau, siv hluav taws xob, thiab tau txais los ntawm ntau tus neeg teb xov tooj hauv paus chaw nres tsheb los xyuas kom muaj kev ruaj ntseg.
2, Lub TD-LTE sab nraum zoov kev sib koom ua ke muaj kev sib koom ua ke siab thiab sib koom ua ke ntawm cov tub ntxhais network, BBU thiab RRU kom ntseeg tau tias lub zog ntawm lub zog loj hauv cheeb tsam kev pab cuam thaum txhim kho kev ua haujlwm ruaj khov ntawm cov khoom siv.Kev sib xyaw ua ke txhawb nqa IP67 tsis muaj dej tsis zoo thiab hloov mus rau qhov chaw nyuaj thiab huab cua phem.
3, Lub TD-LTE sab nraum zoov kev koom ua ke thiab CPE yog them los ntawm tub rog-civilian fusion zaus band (566-606 zaus cov ntsiab lus).Qhov chaw tsis tshua muaj kev poob qis yog qhov me me, thiab kev sib kis nrog lub peev xwm muaj zog diffraction kom ntseeg tau tias bandwidth thiab nce qhov kev ncua deb.
4, CPE industrial-qib IP67 yog waterproof, yoog mus rau qhov nyuaj sab nraum zoov ib puag ncig, thiab industrial-qib zoo txhim kho bandwidth thiab stability.Kev sib koom ua ke thiab kev siv hluav taws xob nrog cov khoom siv huab cua.
Marine kev pov hwm kev kuaj xyuas.
Cov khoom siv tau teeb tsa hauv lub tsev siab ntawm Dishui Lake hauv Shanghai, uas sim Yangshan Chaw nres nkoj thiab Hangzhou Bay feem.Lub hauv paus chaw nres tsheb yog xa mus rau lub sij hawm nrog ib tug tripod ncej (33m saum toj no hiav txwv theem), thiab qhov siab tshaj plaws kev xeem nyob deb yog 54km.
CPE teeb liab lub zog-74, lub xov tooj ntawm tes (200mw) ib txwm nkag, kev lag luam ib txwm, pom meej thiab du video.Cov kev xav tau ntawm qhov project nyob rau lub sijhawm ntawd tau ua tiav, thiab kev sim ntxiv tsis tau ua tiav.Nws tuaj yeem ua tiav kev pabcuam txuas ntxiv ntawm cov dej ntawm Yangshan Island thiab Drishui Lake.
