Tomas Chlebek Kuyambira masiku antennagate a iPhone 4, kulondola kwa chizindikiro chamtundu wamtundu wa mafoni a m'manja wakhala mutu wokambirana pafupipafupi. Iwo omwe sakhulupirira mabwalo opanda kanthu ndi odzazidwa pakona ya chiwonetsero amatha kuwasintha mosavuta ndi nambala yomwe iyenera, makamaka mwachidziwitso, kupereka mtengo wodalirika.
Mphamvu ya sigino nthawi zambiri imayezedwa ndi decibel-milliwatts (dBm). Izi zikutanthauza kuti gawoli likuwonetsa chiŵerengero chapakati pa mtengo woyezedwa ndi milliwatt imodzi (1 mW), zomwe zimasonyeza mphamvu ya chizindikiro cholandiridwa. Ngati mphamvuyi ndi yapamwamba kuposa 1 mW, mtengo wa dBm ndi wabwino, ngati mphamvu ili yochepa, ndiye kuti mtengo wa dBm ndi woipa.
Pankhani ya chizindikiro cha foni yam'manja ndi mafoni a m'manja, mphamvu imakhala yochepa nthawi zonse, kotero pali chizindikiro choipa pamaso pa chiwerengero cha dBm unit.
Pa iPhone, njira yosavuta yowonera mtengo ndi iyi:
- Lembani *3001#12345#* mu dial field (Phone -> Dialer) ndikudina batani lobiriwira kuti muyambe kuyimba. Izi ziyika chipangizochi mu Field Test mode (yogwiritsidwa ntchito mwachisawawa panthawi ya ntchito).
- Pomwe chiwonetsero cha Field Test chikuwonekera, dinani ndikugwirizira batani logona mpaka chophimba chotseka chiwonekere. Musati muzimitsa foni (ngati mutero, palibe choipa chomwe chidzachitike, koma muyenera kubwereza ndondomekoyi).
- Dinani ndikugwira batani la desktop mpaka desktop iwonekere. Kenako, pakona yakumanzere yakumanzere kwa chiwonetserocho, m'malo mwa mabwalo apamwamba, kuchuluka kwa manambala amphamvu yazizindikiro mu dBm kumatha kuwoneka. Mwa kuwonekera pa malowa, ndizotheka kusinthana pakati pa mawonedwe apamwamba ndi mawonetsedwe a chiwerengero cha chiwerengero.
Ngati mukufuna kubwereranso ku chiwonetsero champhamvu cha siginecha kachiwiri, bwerezani gawo 1 ndipo zenera la Field Test litawonetsedwa, ingodinani pang'ono batani lapakompyuta.
Makhalidwe mu dBm ndi, monga tafotokozera pamwambapa, nthawi zonse amakhala olakwika pazida zam'manja, ndipo kuyandikira nambalayo ndi zero (ndiko kuti, ili ndi mtengo wapamwamba, poganizira chizindikiro choyipa), chizindikirocho chimakhala champhamvu. Ngakhale manambala omwe amawonetsedwa ndi foni yam'manja sangathe kudaliridwa kwathunthu, amapereka chizindikiritso cholondola kwambiri kuposa mawonekedwe osavuta owonetsera. Izi ndichifukwa choti palibe chitsimikizo momwe zimagwirira ntchito ndipo, mwachitsanzo, ngakhale ndi mphete zitatu zodzaza, kuyimba kumatha kutha, ndipo m'malo mwake, ngakhale imodzi ingatanthauze chizindikiro chokwanira chokwanira.
Pankhani ya ma dBm, manambala apamwamba kuposa -50 (-49 ndi pamwambapa) ndi osowa kwambiri ndipo ayenera kuwonetsa kuyandikira kwambiri kwa chotumizira. Manambala kuyambira -50 mpaka -70 akadali apamwamba kwambiri ndipo ndi okwanira chizindikiro chapamwamba kwambiri. Mphamvu yapakati komanso yodziwika bwino imafanana ndi -80 mpaka -85 dBm. Ngati mtengo uli pafupi -90 mpaka -95, zikutanthauza chizindikiro chotsika kwambiri, mpaka -98 chosadalirika, mpaka -100 chosadalirika kwambiri.
Mphamvu ya siginecha yochepera -100 dBm (-101 ndi pansi) zikutanthauza kuti ndi yosatheka kugwiritsa ntchito. Ndi zachilendo kuti mphamvu ya siginecha isiyanitse pafupifupi ma dBm asanu, ndipo zinthu monga kuchuluka kwa zida zomwe zimalumikizidwa ndi nsanja, kuchuluka kwa mafoni omwe akuchitika, kugwiritsa ntchito foni yam'manja, ndi zina zambiri. zotsatira pa izi.
pomwe izi zimakhudzidwa ndi zinthu monga kuchuluka kwa zida zolumikizidwa ndi nsanja, kuchuluka kwa mafoni omwe akuchitika, kugwiritsa ntchito mafoni am'manja, ndi zina zambiri.
… kulanda chipangizo… :-D
mwinamwake, pamene munthu ali pa zenera kunyumba, pogogoda chala pa siginali, izo kusintha pakati madontho ndi dBm...
Ndiko kulondola, munthu amakakamizika ku ma code amphamvu ndi machitidwe omwe ali ndi mabatani, pamene zonse zomwe muyenera kuchita ndikugwedeza chala chanu pa chizindikirocho ndipo chimasintha mmbuyo ndi mtsogolo. ? Chabwino, osachepera mmodzi amadabwa pa zobisika menyu, amene akadali zothandiza. ?
Ndinayesa, koma mwanjira ina sizinagwire ntchito popanda code i7 chipangizo ndi mapulogalamu atsopano
Ndili ndi iP5, iOS yaposachedwa, ndipo imagwira ntchito ngakhale pazenera lokhoma, polowa ma code, komanso pama desktops okhala ndi zithunzi. Sindikudziwa kuti mafoni atsopano ali bwanji, ndifunsa mnzanga. ?
Ndipo ngati ndikufuna kubwezera momwe zinalili poyamba? Zikomo
Timalemba m'mawuwo: Ngati mukufuna kubwereranso ku chiwonetsero chapamwamba cha mphamvu ya siginecha, bwerezani gawo 1 ndipo chiwonetsero cha Field Test chikawonetsedwa, ingodinani pang'ono batani lapakompyuta.
Zabwino kwambiri, zikomo kwambiri!
Zimandiwonetsa -110 ndi kuzungulira -89, kotero sindikudziwa komwe kulakwitsa kuli. Kuitana kumagwira ntchito.
Ndili ndi - 102 ndikusintha 3 thovu. Komabe, chizindikirocho chikuwoneka chokwanira, zonse zimagwira ntchito bwino. Ndipo molingana ndi inu, siziyenera kutero. Chabwino, sindikudziwa………………..
