Kana wakambotarisa foni yako, uchishamisika kuti sei uine bhaa imwe miniti imwe uye 3 inotevera—kana kuti sei mafoni ako achidonha kunyangwe painoti une sevhisi—pamwe wakasangana neshoko iri."dBm" pane imwe nguva. Ndapedza makore gumi nemana ndichigadzirisa matambudziko emagetsi edzimba, mahofisi, uye kunyange kumaruwa ari kure, uyeNdinogona kukuudza: dBm ndiyo kodhi yakavanzika yekunzwisisa kuti chiratidzo chefoni yako chakasimba (kana kuti hachina simba) zvakadii. Uye chikamu chakanakisa ndechei?IHazvina kuoma sezvazvinonzwika—regai nditsanangure zviri kuitika sekunge tiri kutaura tichinwa kofi.
Kutanga, ngatitsanangure chimwe chinhu: dBm inomiririra "madecibels kana tichienzanisa ne milliwatt imwe chete." Ndinoziva, izvo zvinonzwika semutauro wetekinoroji, asi chaunofanira kurangarira ndeichi:dBm ndiyo inoyera kuti kubatana kwefoni yako nenharembozha kwakasimba seiKusiyana nenhamba zhinji dzawakajaira—apo hukuru huri nani—dBm inoshanda kumashure. Kana nhamba iri pedyo ne0, chiratidzo chako chinowedzera kusimba. Kana ikanyanya kuipa, ndipo painoderera. Ndiyo chikanganiso chekutanga chinoitwa nevanhu vazhinji: vanoona nhamba yakaita se -80 vofunga kuti yakaipa kupfuura -60, asi chaizvoizvo zvinopesana.
Ngatigadzirei izvi nemanhamba chaiwo—auchaona pafoni yako. Kana dBm yako iri pakati pe -50 ne -70, uri panzvimbo yakanaka. Ndiwo ma "full bars", mafoni akajeka, uye data rinokurumidza—hapana buffering, hapana mafoni akadonhedzwa, kungobatanidza zvakanaka. Izvi ndizvo zvaunowana kana wakamira pedyo nenharembozha, kana munzvimbo yakashama isina zvipingamupinyi.
Zvino, kana dBm yako iri pakati pe -70 ne -90, izvozvo zvichiri zvakanaka—uchava nemabhawa maviri kusvika matatu, uye mafoni mazhinji nemaapplication zvinoshanda zvakanaka. Ungangoona kudzikira kwedata nguva nenguva, kunyanya munzvimbo dzine vanhu vakawanda, asi hazvina basa. Uku ndiko kusimba kwemasaini mudzimba zhinji nemahofisi asiri kure zvakanyanya neshongwe.
Dambudziko rinotanga kana wadzvanya -90 kusvika -110 dBm. Izvi zvinoreva bhaa rimwe chete (kana kuti "hapana sevhisi" dzimwe nguva), uye unotanga kuva nematambudziko: mafoni anodonha pakati pehurukuro, mameseji anotora nguva refu kutumira, uye kutenderera hazvigoneke. Izvi zvinowanzoitika mudzimba dzepasi, zvivakwa zvine madziro akakora, kana nzvimbo dziri kure nenharembozha—senge dzimba dzekumaruwa kana mukati memahofisi makuru.
Ko kana dBm yako iri -110 kana pasi? Inzvimbo isina simba. Nhare yako inganetseka kubatana zvachose, uye kunyangwe ikadaro, chiratidzo chacho hachina simba zvekuti hachibatsiri. Ndinozviona nguva dzese mumagaraji ekupaka mota pasi pevhu, mumatunnel, kana mudzimba dzakakomberedzwa nemiti mirefu kana makomo—nzvimbo idzo chiratidzo chacho chisingakwanise kupinda nyore.
Ungave uchishamisika kuti: ndoongorora sei dBm yangu? Zviri nyore, uye haudi maturusi anoyevedza. Pa iPhone, unogona kushandisa Field Test Mode (ingo dhayira *3001#12345#* wobva wadzvanya “LTE” wobva wadzvanya “Serving Cell Meas”) kuti uone dBm yako chaiyo. Pa Android, mafoni mazhinji ane sarudzo ye "Signal Strength" muSettings app, kana kuti unogonaDhawunirodha app yemahara yakaita seCellularZ kuti uwane kuverenga kwakajeka.Kana wangoziva dBm yako, uchaziva kuti chiratidzo chako chakasimba zvakadii—uye kana uchida kuita chimwe chinhu nezvazvo.
Heino chinhu chandinoudza vatengi vangu vese: haufanirwe kurarama nesignali isina simba. Kana dBm yako iri pasi pe -90 nguva dzose, achinowedzera chiratidzo chenetiweki yefoni inogona kubatsira. Inodhonza chiratidzo chedBm chisina simba, chisina kunaka kubva kunze, inochiwedzera, uye inochitumira mukati menzvimbo yako—ichishandura -100 dBm kuita -70 kana kupfuura, saka une sevhisi yakavimbika zvakare, chengetedza mari yako kune chimwe chinhu chinogadzirisa dambudziko.
Ndakaona vanhu vakawanda vachitenga ma booster avasingade, nekuti vanofunga kuti "signal yakawanda iri nani." Asi dBm inotidzidzisa kuti zvine chekuita nekuenzanisa - unongoda signal yakakwana kuti basa riitwe. Chinhu chikuru kuziva nhamba dzako, kuti ugone kuita sarudzo ine ruzivo.
Kana uchiri kuvhiringidzika nezvekuverenga kwako dBm, kana kuti usina chokwadi kana signal booster yakakunakira, usazeza kutaura nesu. Ndinofara kukuratidza nekutarisa signal yako, kutsanangura zvinoreva nhamba dzako, uye kukubatsira kuwanamhinduro iri nyore pamusoro pekuvharwa kwechiratidzoIzvo zvinoshanda munzvimbo yako.
