Chiratidzo Chefoni Chinobva Kupi?

Mubvunzo 1. Chiratidzo chefoni chinobva kupi?
Ndinotenda kuti vanhu vazhinji vakanzwa nezvemazwi maviri ayachiteshi chepasi kana chiteshi chezviratidzo (shongwe), asi chaizvoizvo chinhu chimwe chete. Chiratidzo chefoni chinotumirwa kuburikidza nechinhu ichi chatinoti base station.

Mubvunzo wechipiri. Chii chinonzi mafungu emagetsi?
Zvichitaurwa zviri nyore, mafungu emagetsi iwaya anotenderera anotorwa uye anoburitswa muchadenga neminda yemagetsi nemagineti iri muchikamu uye yakatarisana. Iwaya minda yemagetsi inopararira muchimiro chemafungu uye ine duality yemafungu-particle. Kumhanya kwekupararira: kumhanya kwemwero wechiedza, hapana nzira yekupararira inodiwa (Wave yeruzha inoda nzira). Mafungu emagetsi anonyudzwa uye anoonekwa paanosangana nesimbi, uye anodzikira kana akavharwa nezvivakwa, uye anodzikira kana paine mhepo, mvura uye ine mheni. Kureba kwewavelength kupfupika uye kuwanda kwemafungu emagetsi, ndiko kuwedzera kwedata rinotumirwa panguva imwe neimwe.

Mubvunzo 3. Tingagadzirisa sei chiratidzo?
Pari zvino pane nzira mbiri. Imwe ndeyekuzivisa mushandi wako kuti chiratidzo chemunharaunda hachina kunaka, uye dhipatimendi rekugadzirisa network richaenda kunoedza simba rechiratidzo. Kana simba rechiratidzo risingasvike zvinodiwa, mushandi achavaka nzvimbo yekusimbisa pano kuti avandudze network yako.

Imwe ndeyekushandisa amplifier yesignal yefoni. Nheyo yayo ndeyekushandisa forward antenna (donor antenna) kuti igamuchire downlink signal yebase station mu repeater, kuwedzera signal inobatsira kuburikidza ne low-noise amplifier, kudzvinyirira noise signal iri musignal, uye kuvandudza signal-to-noise Ratio (S/N); wobva wadzikiswa kuita intermediate frequency signal, yakasefetwa ne filter, yakawedzerwa ne intermediate frequency, wobva wachinjirwa frequency wokwidzwa ku radio frequency, yakawedzerwa ne power amplifier, uye yoendeswa ku mobile station ne rear antenna (retransmitting antenna); Panguva imwe chete, uplink signal ye mobile station inogamuchirwa ne backward antenna, uye inogadziriswa ne uplink amplification link munzira yakatarisana: kureva kuti, inotumirwa ku base station kuburikidza ne low-noise amplifier, down-converter, filter, intermediate amplifier, up-converter, uye power amplifier, nokudaro inowana kutaurirana kwenzira mbiri pakati pe base station ne mobile station.

Ma amplifiers efoni anogona kushandiswa munzvimbo dzine vanhu vakawanda mumaguta, mumaguta nemunharaunda, uye kumaruwa. Zviri nyore kushandisa. Ndeipi sarudzo yaunoda?

Linchuang ikambani yetekinoroji yepamusoro inoshandira vashandisi vanopfuura miriyoni imwe munyika nematunhu zana nemakumi mashanu neshanu pasi rose. Munyaya yekutaurirana nefoni, tinosimbirira pakugadzira zvinhu zvitsva zvinoenderana nezvinodiwa nevatengi kuti tibatsire vatengi kugadzirisa zvinodiwa nezviratidzo zvekutaurirana! Linchuang yakazvipira kuva mutungamiri muindasitiri isina simba yekubatanidza zviratidzo, kuitira kuti pasave nenzvimbo dzisina kusimba pasi rose, uye munhu wese anogona kutaurirana pasina zvipingamupinyi!
