Niba wigeze kureba telefoni yawe, ukibaza impamvu ufite umunota umwe n'undi munani—cyangwa impamvu uhamagara nta nteruro nubwo ivuga ko ufite serivisi—ushobora kuba warigeze guhura n'icyo kibazo."dBm" Hari igihe. Namaze imyaka 14 nkemura ibibazo by'amajwi y'ingo, ibiro, ndetse no mu byaro bya kure, kandiNdakubwira: dBm ni kode y'ibanga yo gusobanukirwa uburyo ikimenyetso cya selile yawe gikomeye (cyangwa gifite intege nke). Kandi se, ni iki cyiza kurushaho?INtabwo bigoye nkuko bisa nkaho ari ibintu bigoye—reka mbivuge nk'aho turi kuganira turimo kunywa ikawa.
Ubwa mbere, reka dusobanure neza ikintu kimwe: dBm isobanura "decibels ugereranyije na milliwatt imwe." Ndabizi, ibyo bisa n'amagambo akoreshwa mu ikoranabuhanga, ariko icyo ugomba kwibuka ni iki:dBm ni igikoresho gipima imbaraga za telefoni yawe ku munara wa telefoniBitandukanye n'imibare myinshi umenyereye—aho ikinini ari cyo cyiza—dBm ikora inyuma. Uko umubare wegera kuri 0, niko ikimenyetso cyawe kirushaho gukomera. Uko kirushaho kuba kibi, niko kirushaho kuba gito. Iryo ni ikosa rya mbere abantu benshi bakora: babona umubare nka -80 bakibwira ko ari mubi kurusha -60, ariko mu by'ukuri ni ibinyuranye.
Reka tubikore neza dukoresheje imibare ifatika—iyo uzabona kuri telefoni yawe. Niba dBm yawe iri hagati ya -50 na -70, uri mu mwanya mwiza. Ibyo ni utubari twuzuye, guhamagara neza, n'amakuru yihuta—nta gufunga, nta guhamagara kwavuye, gusa guhuza neza. Ibi nibyo uzabona niba uhagaze iruhande rw'umunara wa telefoni, cyangwa ahantu hafunguye nta mbogamizi.
Noneho, niba dBm yawe iri hagati ya -70 na -90, biracyari byiza—uzaba ufite utubari 2-3, kandi guhamagara na porogaramu nyinshi bizakora neza. Ushobora kubona ko amakuru agenda agabanuka rimwe na rimwe, cyane cyane ahantu hahurira abantu benshi, ariko nta kintu cyo guhangayikishwa nacyo. Ubu ni imbaraga zisanzwe z'amakuru mu ngo nyinshi no mu biro bitari kure cyane y'umunara.
Ikibazo gitangira iyo ukanda kuri -90 kugeza kuri -110 dBm. Ni ukuvuga bar 1 (cyangwa rimwe na rimwe "nta serivisi"), kandi uzatangira kugira ibibazo: guhamagara birahagarara hagati mu kiganiro, ubutumwa bugufi bumara igihe kirekire bwoherezwa, kandi uburyo bwo kohereza ubutumwa muri rusange ntibishoboka. Ibi bikunze kugaragara mu mazu yo munsi y'ubutaka, mu nyubako zifite inkuta nini, cyangwa mu duce turi kure y'iminara y'utugari - nko mu ngo zo mu cyaro cyangwa mu biro binini.
Kandi se niba dBm yawe ari -110 cyangwa munsi yayo? Ni ahantu hatameze neza. Telefoni yawe ishobora kugorwa no guhuza, kandi nubwo yaba imeze gutyo, ikimenyetso kiba gito cyane ku buryo ntacyo kimaze. Ibi ndabibona buri gihe mu magaraje yo munsi y'ubutaka, mu tunnel, cyangwa mu mazu akikijwe n'ibiti birebire cyangwa imisozi—ahantu ikimenyetso kidashobora kwinjira byoroshye.
Ushobora kuba wibaza uti: nte nagenzura dBm yanjye? Biroroshye, kandi nta bikoresho bigezweho ukeneye. Kuri iPhone, ushobora gukoresha Field Test Mode (Kanda *3001#12345#* hanyuma ukande kuri “LTE” hanyuma ukande kuri “Serving Cell Meas”) kugira ngo urebe dBm yawe nyayo. Kuri Android, telefoni nyinshi zifite uburyo bwa "Signal Strength" muri porogaramu y'Igenamiterere, cyangwa ushoboraKuramo porogaramu y'ubuntu nka CellularZ kugira ngo uyisome neza.Umaze kumenya dBm yawe, uzamenya neza imbaraga z'ikimenyetso cyawe—ndetse niba hari icyo ugomba gukora kuri cyo.
Dore ikintu mbwira abakiriya banjye bose: ntabwo ugomba kubaho ufite ikimenyetso gito. Niba dBm yawe ihora iri munsi ya -90,kongerera ingufu umuyoboro wa telefoni zigendanwa ishobora gufasha. Ikuramo ikimenyetso cya dBm gito kandi kibi kivuye hanze, ikacyongerera imbaraga, hanyuma ikacyohereza mu mwanya wawe—igahindura -100 dBm muri -70 cyangwa irenga, bityo ukongera kugira serivisi yizewe, uzigame amafaranga yawe ku kintu gikemura ikibazo koko.
Nabonye abantu benshi bagura ibikoresho byo kongera imbaraga badakeneye, kuko batekereza ko “ibimenyetso byinshi ari byo byiza.” Ariko dBm itwigisha ko ari ukwishyira mu gaciro—ukeneye ibimenyetso bihagije kugira ngo akazi karangire. Ikintu cy'ingenzi ni ukumenya imibare yawe, bityo ukabasha gufata icyemezo usobanukiwe neza.
Niba ukiri mu rujijo ku bijyanye no gusoma dBm yawe, cyangwa utazi neza niba icyuma gitera imbaraga kikubereye, ntutindiganye kukubwira. Nishimiye kukwereka aho ureba ikimenyetso cyawe, gusobanura icyo imibare yawe isobanura, no kugufasha kubonaigisubizo cyoroshye ku bijyanye no gukwirakwiza ibimenyetsoIbyo bikubereye. Nta magambo ahinnye cyangwa amagambo ahinnye—ni inama z'ukuri zivuye ku muntu umaze imyaka irenga icumi akemura ibibazo by'amakuru.
