Tanthauzo:
Ndi maphunziro a nyanja kumbali zonse ziwiri za foni ya mpweya wothandizira foni nthawi zambiri amasiya ogulitsa akusokonezeka, pali mfundo imodzi yomwe ingakuthandizeni kudziwa momwe muyeso wa foni yanu umayendera. Amatchedwa SAR.
SAR ndi "njira yodziŵira kuchuluka kwa mphamvu ya mpweya (RF) yomwe imatengedwa ndi thupi," malinga ndi a Cellular Telecommunications Industry Association (CTIA).
SAR imayimira mlingo woyenerera wokwanira . Pansi penipeni foni yanu SAR, m'munsi mumawonetsetsa kuwala kwa magetsi ndi magetsi omwe amatha kugwiritsa ntchito foni yanu.
Ku North America, mlingo wa SAR wa foni umayesedwa pakati pa 0.0 ndi 1.60 ndi 1.60 yokhazikitsidwa ndi Federal Communications Commission (FCC) ngati msinkhu wa ma radiation umaloledwa.
CTIA imafuna kuti mafoni a m'manja onse ku US azitsatira chiwerengero ichi cha SAR kuchokera ku FCC.
Ku Ulaya, chiwerengero cha SAR chimachokera ku 0.0 mpaka 2.0 monga momwe bungwe la European Union Council linayendera ndipo bungwe la International Commission la Non-Ionizing Radiation Protection (ICNIRP) linalimbikitsa.
Ku North America, SAR imayesedwa pa watts pa kilogalamu (kapena W / kg) pa digiri imodzi ya tizilombo tomwe tizilombo toyambitsa matenda mu Ulaya SAR imawerengeka kuposa magalamu khumi.
Malire a FCC, omwe amaposa galamu imodzi ya minofu ya thupi, ndi yovuta kwambiri kuposa dziko lonse lapansi.
IPhone 3G , mwachitsanzo, ili ndi chiwerengero chachikulu cha SAR cha 1.388. The Motorola Rapture VU30 imalongosola mlingo wapansi wa SAR wa 0.88 pamutu ndi 0.78 pa thupi pamene LG enV 2 imakamba chiwerengero chapamwamba cha SAR cha 1.34 pamutu ndi 1.27 pa thupi.
Kuphatikiza pa kusankha mwatsatanetsatane foni yamtundu wotsika wa SAR, mungathe kuchepetsa kutulukira kwa dzuwa pogwiritsa ntchito mutu wautali wa Bluetooth wosasunthika ( ngati uwu ) kuti musiye foni yanu kapena musagwiritse ntchito telefoni yanu .

malingaliro apadera

Kulingalira kwa ma ARV kwa iPhone 3G ndi 1.388.
