Masiku ano, ndikuwonjezeka pakukula kwa ukadaulo wolumikizirana kwa mafoni, bolodi ya madera osindikizidwa (PCB) mkati mwa mafoni ayamba kukhala chofunikira kwambiri, ndikukhala chinthu chofunikira chachiwiri kwa wailesi yokha kwa wailesi yokha kwa wailesi yokha kwa wailesi.Kuthana ndi kuchuluka kwa ma radio pafupipafupi, malo a pcb a mafoni amanja amakumana ndi zovuta zazikulu.Zovuta izi zimayambira pakuwonjezera kwa wailesi yaziraMakamaka ovuta kwambiri kuti achulukitse ma RF kutsogolo kwa malo ochepa.
Motsutsana ndi ukadaulo uwu, makompyuta a Incrologies Inc. (qTI) wakhazikitsa njira yothetsera vuto la REP3660 ya intaneti, yomwe imalumikiza dongosolo lomwe limagwirizanitsa zinthu zosiyanasiyana pakati pa modem ndi antenna.Mwa kuphatikiza Antetna Switches, RF Expreers, etc.Kuphatikiza apo, yankho ili lingachepetse kukula kwa stu imodzi ndikukulitsa zabwino zopangira.Popeza yankho lidamasulidwa mu February chaka chino, opanga ma oem ayamba kutengera ndipo akuyembekezeka kukhazikitsa zinthu zofananira zisanathe chaka.Njira yothetsera iyi imapangidwa kuchokera ku mawonekedwe owoneka bwino kuchokera kumagawo oyamba ndipo amatha kugwirira ntchito limodzi ndi zinthu zosiyanasiyana za ma harminare osiyanasiyana a terminal kuti ithandizire kusintha kwatsopano.
Pa mulingo waukadaulo, njira yopanga izi imakhazikika pakukula kosalekeza kwa maukonde a padziko lonse lapansi ndi 3g, ndipo imagwiritsidwa ntchito pothetsa vuto la zigawenga za radiortor offect yopangidwa ndi 4G ndi TDD).Kapangidwe kake kameneka kamatha kuthandizira magulu onse ogwirizana pa terminal imodzi kapena pang'ono pang'ono popanda kuwonjezera zofunikira kapena zolimbitsa thupi.
Pamalingo azachuma, kapangidwe kakumapeto kumathandiza opanga ma cellular omwe amapangira ndikuchepetsa kwambiri.M'malo mongofuna mapangidwe 10 osiyanasiyana kuti akwaniritse zofunika zapadziko lonse lapansi, oems amatha kugwiritsa ntchito mapangidwe atatu kapena ochepa popanda kusintha ma board kapena malo owonjezera.
Pomaliza, zovuta zazikulu mu gawo la RF ndi momwe mungathanirane ndi kukula msanga mu chithandizo cha ntchito ndi ma network omwe alibe malo a PCB.Pakadali pano, kuchuluka kwa zigawenga zowirikiza zam'manja mdziko lapansi kwafika 40, ndipo opanga oem amafunikira kukhazikitsa mitundu yosiyanasiyana ya manja kuti akwaniritse zambiri zobwerera pazogulitsa.Mayankho a RF ali ndi malire pothana ndi zovuta izi, ndipo njira yatsopanoyi kuchokera ku zivomerezo zimapereka mwayi watsopano wa opanga mafoni, kuwalola kuti akwaniritse njira zochepetsetsa.
