Radiyo relay kuyananisa maitiro

Nhepfenyuro-relay communication systems (RRS) nhasi ndiyo inonyanya kukosha yekufambisa mashoko emafuratiro: basa rinokosha rehuwandu hwakazara hwehuwandu hwevanhu hunoenderana nechimwe chiyero. Iyi teknolojia inoreva kufambiswa kwemashoko kuburikidza nehutano hwezviteshi zvekare. Nyika yacho inotakura dhidhiyo yemudhiyo mumagetsi ekumhanya uye masentimita, pazvakawanda kubva mazana emamiriyoni eMHz kusvika makumi makumi emakumi maviri eGHz.

Rare relay relay communication systems rine zvinotevera:

- mukana wekutsvaira chiratidzo se narrowband uye broadband;

- multichannel uye duplex (maviri-nzira, kupa uye kugamuchira, uye kutumirwa) kutaurirana pakati pevanyori;

- inenge yakakwana kugadziriswa kwekushungurudzika kwemhepo neyemabhizimusi "background";

- zvishoma, kana achienzaniswa netambo yekutengesa, nguva yekunamatira sangano;

- Narrow directivity yemakemikari antenna, iyo inokonesa kuwedzera kwemazuva ose magetsi emunzvimbo yacho.

Panguva imwe chete, kushandiswa kweRRS hakusi kunze kwezvipingamupinyi zvayo zvinokonzerwa nekudiwa kwekuita kuti:

- high antenna urongwa uye kururamisa geometric "kuonekwa" pakati pevakidzani vanogamuchira / kutumira zviyero;

- kuwedzera mune nhamba yezvivako zvepakati zvichienderana nehuwandu hwechiratidzo chekuendesa kure.

Mukuwedzera, maitiro aya anowedzera kukonzera midziyo yekukurukurirana, uye kuvakwa kwemasvomhu munzvimbo dzakaoma-kusvika-kusvika zvakaoma kuunza nekuisa.

Zvose zviri pamusoro apa zvine basa rinokosha mumutambo iwoyo-relay communication kana zvichibvira, zvinotsiviwa nefiber-optic lines (FOCL). Vanokurudzirwa nekutama kwavo uye kuwedzera kwekufamba kwemigwagwa, mitoro yekutakura mitambo. Munharaunda dzemaguta, FOCL ichadzika zvishoma nezvishoma zvishoma nezvishoma, asi ruzivo rweRussia uye humwe hukuru hwekufambiswa kwemashamba ekutakura kunogadzirisa chivimbo chokuti redio relay rekukurukurirana zvigadziriswe zvakanyanya mumakumi emakore anouya. Muhukuru hwenyika yedu nhamba yakawanda yenzvimbo umo kuvakwa uye kuiswa kwefiber-optic mitsara haingambotori.

Uye kunyange nekushandiswa kwefiber sezvinonyanya kushandiswa, hapana chikonzero chekuvapo kwekuchengetedza, nokuti mitsara yemakabhesi inowanzotadza kuputsa uye, sechikonzero, nguva refu yakaderera. Uye sekuchengetedzwa kweredhiyo relay system inotaurirana haitomborwi.

Uyezve, munhu anogona kutaura kwete chete nezvekuchengetedzwa kwavo, asiwo nezvekuwedzera kwekusimudzirwa: chinhu chitsva ichi chinotipa isu TV inopinda muupenyu hwedu. Mukuronga kuparadzirwa kweterevhizheni yemudhidhiyo, RRS ndiyo nzira yakanakisisa, inopa iyo yakagamuchirwa yakanakisisa yekukurukurirana, inodhura nekukurumidza kwekuendeswa. Izvi zvinonyanya kuzivikanwa kana kuparidzirwa mune imwe-frequency mode. Uye maererano nekunyoresa kwekutumira / kubhadhara kwemichina nekuwana zvibvumirano, inofanirwa kuwedzera kufarira kuRRS kubva kumabhizimisi nemasangano mukugadzirwa kwemakambani emakambani.
