Haina Kingtone B2+B5 whakakaha tohu tohu 4g rua roopu 850/1900 gsm pcs 2g 3g hiko hiko hiko 5W,10W,20W cdma pcs waea waea whakahiato tohu kua hangaia hei whakaoti rapanga o te tohu waea wak, he iti ake te utu atu i te taapiri i te teihana turanga hou. (BTS).Ko te mahi matua o nga kaikorero ko te whiwhi tohu iti-kaha mai i te BTS ma te tuku RF katahi ka tuku i te tohu whakakaha ki nga waahi kaore i te tika te kapi o te whatunga. te ritenga atu.
Pūnaha Apple: waeahia : *3001#12345#* ,ka whakaatu te kaha tohu ki te kokonga maui o runga.
Pūnaha Samsung : waea : *#0011#
Ka taea ranei e koe te tango i te taupānga "LTE Discovery" hei tirotiro.
Tuhia to waea ki reira ki te tirotiro i te kaha o te tohu ki waho:
Android : tautuhinga → mo te waea → tūnga → whatunga , ka noho te whakaaturanga dbm i -75dbm ki -85dbm huri noa ;
Nga Waea Whakaritea-rua mo to tohutoro, whiriwhiria nga roopu-2:
Ko B1 (2100) ko te Band 1 i runga i te 2100 MHz.
Ko B2 (1900) ko te Band 2 i runga i te 1900 MHz.
Ko B3 (1800) ko te Band 3 i runga i te 1800 MHz.
Ko B4 (AWS) te roopu 4 i runga i te AWS 1700/2100MHz.
Ko B5 (850) te roopu 5 i runga i te 850 MHz.
Ko B7 (2600) ko te Band 7 i runga i te 2600 MHz.
Ko B8 (900) ko te Band 8 i te 900 MHz.
Ko B20 (800) ko Band20 i runga i te 800MHz
