Antennas nokuti Internet. Satellite dhishi nokuti Indaneti: mutengo

Satellite Internet ndeimwe nzira kuvhura yose mashoko Network. Chokukomborerwa vakabudirira nokushanda World Wide Web ndiyo kumhanya chokuendesa mashoko akakumbira mashoko hwakanaka zvokuratidzira kwayo. Nokuda samambure kuzara haisi nguva zvinogoneka kana uchishandisa dhayira-up kwokubatana pahwaro runhare kana zvakatsaurirwa mitsetse. Rinogona kutsiva that no wired rokugadzirisa yazova zvemichina uchishandisa Satellite dhishi kuti paIndaneti.

Sei basa iri

Kukurukurirana inobva nenhungamiro digitaalinen Satellite kutepfenyura mureza DVB-S: asi Chirungu Digital Video Broadcasting - Satellite (Digital Video Broadcasting Via Satellite). Maererano neizvi Satellite ezvinhu dzaishandisa govera Mwedzi mumwe kana kupfuura mugero kuti sangano mukuru-nokukurumidza Data hurukuro kuti Kero user. Kubva midziyo zvakakodzera Internet TV kanyanga User chinouraya, convert nezvimwe namano.

Data ari inoparadzirwa pamwechete terevhizheni anonongedzera uye makaseti nhepfenyuro, uye chiri kuitwa nenzira vakawanda vanoshandisa munharaunda basa. Muchiitiko chino, zvinoita kero (pachavo) chokuendesa mashoko akumbira mashoko kubva Internet uye kumhanyira kuparadzira mashoko (mafirimu, nziyo, nhau, etc.) To nemapoka vanoshandisa pamusoro kuzvinyoresa. Kugamuchira date inotevera Satellite Internet uye transmits kuti kombiyuta (terevhizheni).

Nzira chivakwa nehurongwa

Senzira ruzivo urwu okuita mbiri dziri nzira yokuvaka enyika:

• aibatanidza (spachiana);
• bi achitaura (zvakafanana, ichibata).

In wokutanga (kukabatanidzwa) akashandisa marudzi maviri migero:

• Ground (ruvhesi) - chikumbiro nokuti sangano;
• kwomwedzi (yakananga) - nokuti chokuendesa mashoko vanoshandisa.

In wechipiri nzira (bidirectional) mashoko mukutsinhana ari mberi uye shure mirayiridzo Satellite migero chete zvinobatanidzwa.

aibatanidza nzira

Mune nzira akabatana rokuvaka pano mugero hurongwa - zvetsika. kombiyuta The rokushandisa zvakabatana omunharaunda midziyo Provider (ISP) minamato Via munhu that no wired Modem kubatana kana vachishandisa cellular redhiyo. Wakaiswako Via mashoko Satellite norudaviro awakawana munhu chikwata zvinosanganisira Mwedzi dhishi nokuda internet, yakaderera ruzha convert DVB-PCI makadhi (ane inowanikwa kune PC) uye PC pacharo.

The zvakafanana, ichibata nzira

Mugore bidirectional hurongwa kuvaka nzira inodzidzisa ane rinotengeswa nevaridzi inouraya kuti pakuronga mubvunzo uye nekugamuchira mhinduro ruzivo Via Satellite. channel pano mune shanduro iyi havadikanwi uye zviteshi inogona iri rinonyanya kure makona zvifambiso zvekutepfenyura. Kana kero Delivery Data kudzoka mugero chechikamu rose rinoramba riri kudiwa sangano kusimbisa akarurama vaigamuchira mashoko. Kana kudirana kumudzosa mugero anogona akaremara mushure chikumbiro, uye akakumbira mashoko chakasvitswa inodzidzisa kombiyuta (maererano nokuzivikanwa remitemo) pasina yokupindira ake. Nokuti chikumbiro kumhanyira kugutsikana, unogona kushandisa serura pamwe mashoko Kupfuudzwa mashandiro paIndaneti. Muchiitiko chino, zvakare, pasina Satellite dhishi kuti internet uye akabatanidza midziyo haagoni kuita.

How kubatanidza nzira yacho kukabatanidzwa

Chokutanga, rinotengeswa nevaridzi unopinda chibvumirano, inobhadhara motokari. Zvadaro vanogadzirisa Mwedzi dhishi kuti Indaneti nenzira iri Satellite, iyo iri kutarisirwa kutungamirira mabiko. Zvino unofanira kumhanya software uye dzishandise Satellite mugero parameters.

Via imwe Modem kana cellular rezvebonde anokurukura yomunzvimbo Internet Provider, izvo pashure pakuongorora kuwana kodzero pomumbure kukero yakagoverwa kuna kombiyuta User muna Internet Protocol (IP-kero), nemamwe kuti Network ichi. User date iri chakasvitswa kuti Satellite mabasa Provider Server kuti encrypt navo uye kutumira chikumbiro kuna Internet. The zvichiguma apindure nemambure parameters ikashandiswa kupinda digital date rukova nevamwe vanoshandisa uye yakapiwa yenyika mugero kuparadzira Satellite kutepfenyura chechitima. The chiteshi yakaitwa rukova kushanduka kupinda omumasherufu DVB-S format, kukanganisa kudzora Coding, vachisiyanisa inzwi uye kupararira redhiyo anonongedzera kuna Satellite.

Data Kutamisirwa Rate

Typical digitaalinen rukova Data mwero iri 45-50 Mbit / s. mashoko akananga subscribers makarindira dynamically vachinje zvichienderana nebasa ravo, ivo akakumbira unhu basa, mhando basa, etc. The paavhareji date mwero mumwe User is 150-200 kbit / s, kunonyanyisa - .. anenge 2.5 Mbit / s.

midziyo

At kugamuchirwa divi Via nomumwe kugadzwa chichigamuchirwa anonongedzera kubva satellites, pamusoro basa kuzivikanwa kero anobudiswa "kuziva" kuti mashoko kune user. Kanyanga gudzazwi Internet chiratidzo unowanzovapo zvaizopedza pamwe yatarwa kana tunable nzira achinongedza panguva Satellite. saizi yayo raanotaura panguva kunyoresa, nokuti Key-bhendi (10.7-12.75 GHz) ndiyo 0.6-1.2 m.

The kanyanga nokuti Internet Modem iri nepokuongorora convert riri kutaura pamusoro kanyanga uye zvakabatana imwe waya pamwe DVB-PCI kadhi. Zviri nyore-digital mugamuchiri chakatorwa kuti kuisa mune pachako kombiyuta. Converter kungava zvakasikwa kana kaviri, rimwe kana maviri outputs, ukuwo. The goho yechipiri yemanyorero kushandiswa kubatanidza digitaalinen mugamuchiri kuti vakazvimiririra mapurogiramu TV nevamwe vanoshandisa.

Most dzikabereka DVB-PCI kadhi akagadzirirwa kubata Internet Data TV pamusoro PC. Vamwe vavo vanogona retrofitted aine vhidhiyo encoder kuti kugoverwa purogiramu dzeterevhizheni pamusoro TV, uyewo zvimiso kuwana kadhi muverengi kuti kuisa rinotengeswa nevaridzi makadhi panguva negashiro coded zvirongwa.

How kubatanidza kuti bidirectional nzira

Ezvinhu bidirectional Satellite Internet mukana chikumbiro uye chokuendesa mashoko akatakurwa ari Satellite kukurukura mugero nokushandisa mushandisi inouraya. Inoitwa vezvikwata zviviri:

• External aida kuti transceiving yakakwirira maitikiro anonongedzera;
• zvemukati (iri mumba) - nokuti digitaalinen kubudiswa kuuya uye ichibviswa mashoko.

Pano hadzisisina munzvimbo pfungwa imwe parabolic kanyanga nzvimbo paIndaneti uye chokuita indoor chikwata zviviri coaxial netambo. nokushanda chinouraya zvive zvakasiyana maitikiro zvisungo dzinounzwa kuti sangano Satellite pakukurukurirana uye nhepfenyuro. Vachikumbira nokugamuchira norudaviro Data rakarongwa kuburikidza nechepakati penyika yemapurisa uye kuongorora iri geostationary muchadenga.

The chiteshi ane kuwana mambure uye anopa kupanana ruzivo, kuzvidzora uye kurapa zvose rinotengeswa nevaridzi zviteshi iri munharaunda basa. Kuwedzera date kubudiswa zviteshi vanokwanisa kugamuchira TV chirongwa anonongedzera kurira nhepfenyuro uye dzishandise parunhare facsimile.

vanozvishandisa

zviteshi vose vakagadzirira pamwe hwokufananidzira rezvebonde inowanikwa kushandiswa munzvimbo network. The chikuru vatengi yemabasa inopiwa zvemichina ichi, vari mabhanga, paruzhinji masangano, makambani maindasitiri, Telecom dzaishandisa.

Chipingamupinyi kune vakawanda kuitwa ruzivo urwu mune Kishi nyika ndiyo nyaya kunyoresa mvumo kuti kodzero kunoshanda Satellite network, yakakwirira pamwedzi muripo mabasa avo, kanyanga zvinodhura nokuda Internet, mutengo izvo anoda kubva 2,000 (nyore kusarudza) kusvika 10 000 uye mamwe rubles. Asi chikuru chipingamupinyi ndiye kudhura rinotengeswa nevaridzi zviteshi kuti voga vanoshandisa (anenge 2-2,5 zviuru. Cu). Saka, tine Satellite Data Exchange michina uchishandisa User zviteshi vakagamuchira kushanda pakati yemakambani vanoshandisa.
