Khetha lisebelisoa ka bobeli hore li be boemong ba TRX kapa e 'ngoe ea tsona e be RX' me e 'ngoe e be ka mokhoa oa TX (hlokomela hore lisebelisoa tsa motheo tsa Si4355 li ka ba ba amohelang feela le lisebelisoa tsa Si4012 e ka ba li-transmitters feela). Khetha li-parameter tsa demo tse hlokahalang kapa qala litekanyo ka tlhophiso e kentsoeng bocha.
Lekola hore na transmitter e romella lipakete le likarabo tsa moamoheli.
Teko ea mefuta e fapaneng e ka etsoa ka har'a mohaho haeba tlhahiso ea ka hare e lekoa. Leha ho le joalo, ho eletsoa ho etsa tlhahlobo ka ntle ho moaho, mola-ea-pono ho fumana sephetho se setle ka ho fetisisa se ka khonehang. Haeba PER> 1%, tsosolosa PER ho transmitter 'me u leke ho tsamaea ho ea sebakeng seo. Maemo a phatlalatso hangata a ntlafala haeba mosebelisi a le hole le sebaka se ka bang moriti.
