3.2 DFS itandukanye gato
Ibikoresho byohereza bidasubirwaho bigomba gukoresha Dynamic Frequency Selection (DFS) ikorana buhanga ryo guhagarika ibikorwa, bigomba guhinduka kandi ntibishobora gushyirwaho nuburyo bwo kuzimya DFS.
Kwiyongera kubikoresho byogukwirakwiza bidasubirwaho bigomba gukoresha tekinoroji yo guhagarika imiyoboro ya Transmission Power (TPC), hamwe na TPC itarenze 6dB; Niba nta mikorere ya TPC ihari, imbaraga zingana zingana zose hamwe nimbaraga zingana zingana zose zigomba kugabanuka na 3dB.
3.3 Ongera ikizamini cyo kwirinda
Uburyo bwo kwirinda kwirinda kwivanga burahuza ahanini nibisabwa guhuza n'imihindagurikire y'ikirere cya CE.
3.3.1 2.4G ibisabwa byo kwirinda kwivanga:
HenIyo bigaragaye ko inshuro zakozwe, ihererekanyabubasha ntirigomba gukomeza kuri iyo miyoboro, kandi igihe cyo guturamo ntigishobora kurenga 13m. Nukuvuga ko kwanduza bigomba guhagarikwa mugihe cyateganijwe cyumuyoboro.
Igikoresho kirashobora kugumya kohereza ibimenyetso bigufi byoherejwe, ariko inzinguzingo yinshingano yikimenyetso igomba kuba munsi cyangwa ingana na 10%.
3.3.2 5G ibisabwa byo kwirinda kwivanga:
HenIyo bigaragaye ko hari ikimenyetso gifite inshuro zikoreshwa kurenza igipimo cyo gutahura, ihererekanyabubasha rigomba guhita rihagarikwa, kandi umwanya ntarengwa wo guturamo ni 20ms.
② Mugihe cya 50m yo kwitegereza, umubare wibimenyetso bigufi byerekana ibimenyetso byoherejwe bigomba kuba munsi cyangwa bingana ninshuro 50, kandi mugihe cyo kwitegereza hejuru, igihe cyose cyo kohereza ibimenyetso bigufi byohereza ibikoresho bigomba kuba munsi ya 2500us cyangwa Inshingano yumwanya muto yerekana ibimenyetso byo kohereza ntibigomba kurenga 10%.
3.3.3 5.8G Ibisabwa Kwirinda Kwivanga:
Haba n'amabwiriza ashaje ndetse na CE, nta gisabwa kugirango wirinde kwivanga 5.8G, bityo kwirinda 5.8G birinda bitera ingaruka nyinshi ugereranije na 5.1G na 2.4G wifi.
3.3.4 Ibisabwa birinda Bluetooth (BT):
SRRC nshya isaba kwipimisha kwivanga kuri Bluetooth, kandi nta bihe bisonewe (icyemezo cya CE gisabwa gusa kububasha burenze 10dBm).
Ibyavuzwe haruguru nibikubiye mumabwiriza mashya. Turizera ko buriwese ashobora kwitondera igihe cyemewe cyo kwemeza ibicuruzwa bye nibitandukaniro mugupima ibicuruzwa bishya mugihe gikwiye. Niba ufite ikindi kibazo kijyanye namabwiriza mashya, nyamuneka ubaze inama igihe icyo aricyo cyose!
