Base Station

Base chiteshi inzvimbo yeruzhinji nharembozha yekutaurirana base chiteshi, inova nzira yeredhiyo. Zvinoreva nhepfenyuro yeredhiyo inofambisa ruzivo nematerminals enharembozha kuburikidza nenhare yekufambisa nhare yekuchinja mune imwe nzvimbo yeredhiyo. Mhando dzayo dzinogona kukamurwa muzvikamu zvinotevera:Macro base zviteshi, zvakagoverwa base zviteshi, SDR base zviteshi, vanodzokorora, nezvimwewo.

Macro base station

Macro base zviteshi zvinoreva kune isina waya chiratidzo-yekutumira base nhepfenyuro yevanotaurirana vanoshanda. Macro base zviteshi zvinovhara kureba, kazhinji 35 km. Iwo akakodzera nzvimbo dzine traffic yakapararira mumasabhabhu. Vane omnidirectional coverage uye simba guru. Micro base zviteshi zvinonyanya kushandiswa mumaguta, inovhara chinhambwe idiki, kazhinji 1-2km, ine nzira yekuvhara.Mzviteshi zvecrobase zvinonyanya kushandiswa kuvharidzira mapofu munzvimbo dzinopisa dzemadhorobha. Kazhinji, simba rekufambisa idiki kwazvo, uye chinhambwe chekuvhara 500m kana pasi. Iyo simba remidziyo ye macro base zviteshi kazhinji 4-10W, iyo inoshandurwa kuita isina waya chiratidzo reshiyo ye36-40dBm. Kuwedzera kuwana kwe20dBi kweiyo base station yekuvhara antenna ndeye 56-60dBm.

DistributedBaseStation

Distributed base stations chizvarwa chitsva chezvigadzirwa zvemazuva ano zvinoshandiswa kupedzisa network network. Chinhu chayo chikuru ndechekuparadzanisa redhiyo frequency processing unit kubva kune yechinyakare macro base station baseband processing unit uye kuibatanidza kuburikidza neoptical fiber. Pfungwa yepakati yeiyo yakagoverwa base chiteshi chimiro ndeyekuparadzanisa yechinyakare macro base chiteshi baseband processing unit (BBU) uye radio frequency processing unit (RRU). Iwo maviri akabatanidzwa kuburikidza ne optical fiber. Munguva yekuendesa network, iyo baseband processing unit, core network, uye isina waya network yekudzora michina yakanamirwa mukamuri rekombuta uye yakabatana neredhiyo frequency remoti unit inoiswa panzvimbo yakarongwa kuburikidza neoptical fiber kuti ipedze kuvharwa kwetiweki, nokudaro kuderedza mari yekuvaka nekugadzirisa. uye kuvandudza kushanda zvakanaka.

Iyo yakagoverwa base chiteshi inokamura iyo yechinyakare macro base station midziyo kuita maviri anoshanda mamodule zvinoenderana nemabasa. Iyo baseband, main control, kutapurirana, wachi, uye mamwe mabasa eiyo base station akabatanidzwa mune module inonzi baseband unit BBU (Base Band Unit). Iyo unit idiki muhukuru uye nzvimbo yekuisa inochinjika zvakanyanya; iyo yepakati-renji redhiyo frequency senge transceiver uye simba amplifier inosanganiswa mune imwe inonzi kure kure radio frequency module, uye redhiyo frequency unit RRU (Remote Radio Unit) inoiswa kumagumo eantenna. Iyo redhiyo frequency unit uye baseband unit yakabatana kuburikidza neoptical fibers kugadzira itsva yakagoverwa base chiteshi mhinduro.

SDRBaseStation

SDR (Software Definition Radio) i "software yakatsanangurwa radio", inova isina waya yekutepfenyura yekutaurirana tekinoroji, zvakanyanya, inzira yekugadzira kana dhizaini pfungwa. Kunyanya, SDR inoreva isina waya yekutaurirana protocol yakavakirwa patsanangudzo yesoftware pane yakatsaurirwa hardware kuita. Parizvino pane matatu makuru eSDR hardware papuratifomu zvimiro: GPP-yakavakirwa SDR chimiro, Munda Programmable Gate Array (FPGA)-yakavakirwa SDR (Isiri-GPP) chimiro, uye GPP + FPGA/SDP-yakavakirwa hybrid SDR chimiro. Iyo SDR chimiro chakavakirwa paGPP ndechinotevera.

Iyo SDR base chiteshi ndeye base chiteshi sisitimu yakagadzirwa uye yakagadziridzwa zvichibva pane iyo SDR pfungwa. Chinhu chayo chikuru ndechekuti nhepfenyuro yayo yeredhiyo inogona kurongwa uye kutsanangurwa patsva, uye inokwanisa kuona hungwaru kugovaniswa kweiyo spectrum uye tsigiro yeakawanda network modes, ndiko kuti, inogona kushandiswa papuratifomu imwe chete. Tekinoroji yekushandisa akasiyana network modhi, sezvakaratidzwa mumufananidzo uri pasi apa, GSM + LTE network inoshandiswa pane imwechete yemidziyo.

RP inodzokorora

RP inodzokorora: Iyo RP inodzokorora inoumbwa nezvikamu kana mamodule senge antennas,RF duplexers, low-noise amplifiers, vasanganisi, ESCatenuators, filters, magetsi amplifiers, nezvimwewo, kusanganisira uplink uye downlink amplification links.

Musimboti webasa rayo ndewekuti: kushandisa antenna yekumberi (donor antenna) kugashira iyo downlink chiratidzo cheiyo base chiteshi mune inodzokorora, wedzera iyo inobatsira chiratidzo kuburikidza neyakaderera-ruzha amplifier, kudzvanya chiratidzo cheruzha muchiratidzo, uye kunatsiridza mwero wechiratidzo-kune-ruzha (S/N). ); yobva yadzoserwa pasi-inoshandurwa kuita chiratidzo chepakati, yakapepetwa nesefa, inokwidziridzwa neiyo yepakati frequency, uye yozokwira-inoshandurwa kuita redhiyo frequency, inokwidziridzwa nemagetsi amplifier, uye inotumirwa kunharembozha neantenna yekumashure (retransmission. antenna); panguva imwecheteyo, antenna yekumashure inoshandiswa Iyo uplink siginecha kubva kunhare mbozha inogamuchirwa uye inogadziriswa neiyo uplink amplification link munzira yakatarisana: ndiko kuti, inopfuura nepasi-ruzha amplifier, pasi-inoshandura, sefa, yepakati. amplifier, up-converter, uye simba amplifier isati yaendeswa kune base station. Izvi zvinowana nzira mbiri dzekukurukurirana pakati peiyo base station uye mobile station.

Iyo RP inodzokorora ndeye isina waya chiratidzo relay chigadzirwa. Zviratidzo zvikuru zvekuyera kunaka kweanodzokorora zvinosanganisira dhigirii rehungwaru (zvakadai sekutarisa kure, nezvimwewo), yakaderera IP3 (isingasviki -36dBm pasina mvumo), yakaderera ruzha chinhu (NF), kuvimbika kwemuchina, mabasa akanaka ehunyanzvi. , nezvimwewo.

RP inodzokorora chishandiso chinobatanidza mitsara yetiweki uye chinowanzo shandiswa kune bidirectional kuendesa mberi kwemasaini emuviri pakati petiweki node mbiri.

Repeater

Iyo inodzokorora ndiyo yakapusa network yekubatanidza mudziyo. Inonyanya kupedzisa mabasa emuviri wemuviri. Iyo ine basa rekufambisa ruzivo zvishoma nezvishoma pachikamu chemuviri chenodhi mbiri uye kupedzisa kopi yechiratidzo, kugadzirisa, uye kusimudzira mabasa ekuwedzera kureba kwetiweki.

Nekuda kwekurasikirwa, simba rechiratidzo rinofambiswa pamutsetse richadzikira zvishoma nezvishoma. Kana iyo attenuation ichisvika pane imwe nhanho, inokonzeresa kukanganisa kwechiratidzo, zvichizotungamira mukukanganisa kwekugamuchira. Vanodzokorora vakagadzirirwa kugadzirisa dambudziko iri. Iyo inopedzisa kubatanidzwa kwemitsara yemuviri, inosimudzira iyo yakaderedzwa chiratidzo, uye inoichengeta yakafanana neyekutanga data.

Kuenzaniswa nezviteshi zvepasi, ine zvakanakira chimiro chakareruka, kushoma kwekudyara, uye nyore kuisirwa. Inogona kushandiswa zvakanyanya munzvimbo dzemapofu uye nzvimbo dzisina simba dzakaoma kuvhara, dzakadai semashopu, mahotera, nhandare dzendege, docks, zviteshi, nhandare, nhandare dzevaraidzo, subways, tunnels, etc. Inogona kushandiswa munzvimbo dzakasiyana-siyana dzakadai se. migwagwa mikuru nezvitsuwa kuvandudza kunaka kwekutaurirana uye kugadzirisa matambudziko akadai sekudonha mafoni.

Iko kuumbwa kwenharembozha kudzokorodza kunosiyana zvichienderana nerudzi.

(1)wireless repeater

Iyo downlink chiratidzo inogamuchirwa kubva pachigadziko chiteshi uye inokwidziridzwa kuvhara gwara remushandisi; iyo uplink chiratidzo inogamuchirwa kubva kumushandisi uye inotumirwa kune base chiteshi mushure mekukwidziridzwa. Kudzikamisa bhandi, aband-pass sefainowedzerwa.

(2)Frequency Selective Repeater

Kuti usarudze frequency, iyo uplink uye downlink frequencies inodzika-inoshandurwa kune yepakati frequency. Mushure mekusarudzwa kwefrequency uye bhendi-yekugadzirisa maitiro aitwa, iyo up-link uye downlink frequencies inodzoreredzwa ne-up-conversion.

(3)Optical fiber transmission repeater station

Chiratidzo chakagamuchirwa chinoshandurwa kuva chiratidzo chemaziso kuburikidza nekushandura photoelectric, uye mushure mekutumira, chiratidzo chemagetsi chinodzorerwa kuburikidza ne electro-optical conversion ndokubva yatumirwa kunze.

(4)frequency shift transmission repeater

Shandura frequency yakagamuchirwa kuita microwave, wozoishandura kune iyo yakatanga kugamuchirwa frequency mushure mekutapurirana, ukudze, uye itumire kunze.

(5)Indoor repeater

Iyo yemukati inodzokorora chishandiso chiri nyore, uye zvinodiwa zvacho zvakasiyana neaya ekunze anodzokorora. Iko kuumbwa kwenharembozha kudzokorodza kunosiyana zvichienderana nerudzi.

Semugadziri mutsva weRF zvikamu, tinokwanisa kugadzira & kugadzira mhando dzakasiyana dzezvikamu zvezviteshi zvepasi, saka kana iwe uchida kuziva zvakawanda nezve RF microwave zvikamu, unogamuchirwa kutarisa ruzivo pawebhusaiti yeJingxin.:https://www.cdjx-mw.com/.
