Kuwonetsa kwambiri mphamvu zamawayilesi (RF) kumatha kuwononga minofu yamunthu. Pofuna kupewa izi, mayiko ambiri padziko lonse lapansi akhazikitsa miyezo yomwe imachepetsa kuchuluka kwa mawonekedwe a RF omwe amaloledwa kuchokera ku ma transmit amitundu yonse. BTF ikhoza kukuthandizani kudziwa ngati malonda anu akukwaniritsa zofunikirazo. Timapanga kuyesa kofunikira pazida zosiyanasiyana zonyamula komanso zam'manja zokhala ndi zida zamakono, pogwiritsa ntchito ukadaulo wapamwamba kwambiri, kukupatsirani miyeso yolondola komanso yodalirika ya RF. BTF ndi amodzi mwa mabungwe ochepa omwe angathe kuyesa ndikutsimikizira malonda anu kuti agwirizane ndi miyezo ya RF, komanso miyezo ya chitetezo chamagetsi ndi zofunikira za FCC.
Kuwonekera kwa RF kumawunikidwa pogwiritsa ntchito "phantom" yomwe imatengera mawonekedwe amagetsi amutu kapena thupi la munthu. Mphamvu ya RF yomwe imalowa mu "phantom" imayang'aniridwa ndi ma probes omwe ali bwino omwe amayesa Specific Absorption Rate mu watts pa kilogalamu imodzi ya minofu.
Mtengo wa FCC SAR
Ku United States, FCC imayang'anira SAR pansi pa 47 CFR Gawo 2, gawo 2.1093. Zogulitsa zomwe zimagwiritsidwa ntchito nthawi zonse zimayenera kukwaniritsa malire a SAR a 1.6 mW/g omwe ali pafupifupi pa gramu imodzi ya minofu m'gawo lililonse la mutu kapena thupi, ndi 4 mW/g pafupifupi magalamu 10 a manja, manja, mapazi ndi akakolo.
Ku European Union, malire owonetsetsa a RF adakhazikitsidwa ndi Council Recommendation 1999/519/EC. Miyezo yogwirizana imaphimba zinthu zomwe zimapezeka kwambiri monga mafoni am'manja ndi zida za RFID. Malire ndi njira zowunikira kuwonetseredwa kwa RF mu EU ndizofanana koma sizofanana ndi zaku US.
Maximum Permissible Exposure (MPE)
Ogwiritsa ntchito akamayimitsidwa patali kwambiri amapanga chowulutsira wailesi, chomwe chimakhala chopitilira 20cm, njira yowunikira mawonekedwe a RF imatchedwa Maximum Permissible Exposure (MPE). Nthawi zambiri MPE imatha kuwerengedwa kuchokera ku mphamvu yotulutsa ma transmitter ndi mtundu wa tinyanga. Nthawi zina, MPE iyenera kuyezedwa mwachindunji ndi mphamvu yamagetsi kapena maginito kapena kachulukidwe kamphamvu, kutengera kuchuluka kwa ma transmitter.
Ku United States, malamulo a FCC a malire a MPE amapezeka mu 47 CFR Part 2, gawo 1.1310. Zipangizo zam'manja, zomwe zili zoposa 20 cm kuchokera kwa wogwiritsa ntchito ndipo sizikhala pamalo okhazikika, monga ma telefoni opanda zingwe, zimayendetsedwanso ndi gawo 2.1091 la malamulo a FCC.
Ku European Union, Council Recommendation 1999/519/EC ili ndi malire owonetsetsa kwa ma transmitters osasunthika komanso am'manja. Muyezo wogwirizana wa EN50385 umagwiritsa ntchito malire kumasiteshoni oyambira omwe amagwira ntchito pafupipafupi 110MHz mpaka 40 GHz.
BTF Testing Lab, kampani yathu ili ndi ma electromagnetic compatibility laboratories, ma labotale achitetezo, Laboratory yopanda zingwe, Laboratory ya batri, Laboratory ya Chemical, SAR Laboratory, HAC Laboratory, ndi zina zambiri. Tapeza ziyeneretso ndi zilolezo monga CMA, CNAS, CPSC, A2LA, VCCI, ndi zina zotero. Kampani yathu ili ndi gulu lodziwa bwino ntchito zaukadaulo, lomwe lingathandize mabizinesi kuthetsa vutoli. Ngati muli ndi zofunikira zoyezetsa komanso zotsimikizira, mutha kulumikizana mwachindunji ndi ogwira ntchito athu Oyesa kuti mupeze zambiri zamtengo wapatali komanso zambiri zozungulira!
