3.2 I-DFS ihluke kancane
Izinto ezisetshenziswayo zokudlulisa okungenantambo kufanele zisebenzise ubuchwepheshe bokucindezelwa kokuphazanyiswa kwe-Dynamic Frequency Selection (DFS), okufanele kushintshwe kube futhi obungeke kusethwe ngenketho yokuvala i-DFS.
Ukwengezwa kwemishini yokudlulisa okungenantambo kufanele kusebenzise ubuchwepheshe bokucindezelwa kokuphazanyiswa kwe-Transmission Power Control (TPC), enobubanzi be-TPC obungekho ngaphansi kuka-6dB; Uma ungekho umsebenzi we-TPC, amandla emisebe ye-omnidirectional alinganayo kanye nomkhawulo wokuminyana kwe-spectral wamandla emisebe ye-omnidirectional efanayo kufanele kwehliswe ngo-3dB.
3.3 Ukwandisa ukuhlolwa kokugwema ukuphazamiseka
Indlela yokunquma yokugwema ukuphazamiseka empeleni ihambisana nezidingo zokuguquguquka zesitifiketi se-CE.
3.3.1 2.4G Izidingo zokugwema ukuphazamiseka:
①Uma kutholakala ukuthi i-frequency ihlanziwe, ukudluliswa akufanele kuqhubeke kuleyo mvamisa yesiteshi, futhi isikhathi sokuhlala akufanele sidlule u-13ms. Okusho ukuthi, ukudluliswa kufanele kumiswe phakathi nesikhathi sokuhlala kwesiteshi.
② Idivayisi ingagcina ukudluliswa kwesignali yokulawula okufushane, kodwa umjikelezo wemfanelo wesignali kufanele ube ngaphansi noma ulingane no-10%.
3.3.2 Izidingo zokugwema ukuphazamiseka kwe-5G:
①Uma kutholakala ukuthi kunesiginali enefrikhwensi yokusetshenziswa ephezulu kunomkhawulo wokutholwa, ukudlulisela kufanele kumiswe ngokushesha, futhi isikhathi esiphezulu sokuhlala kwesiteshi ngu-20ms.
② Phakathi nesikhathi sokubuka esingu-50ms, inani lokulawulwa okufushane kokudluliselwa kwesiginali kufanele libe ngaphansi noma lilingane nezikhathi ezingama-50, futhi phakathi nenkathi yokubuka engenhla, isikhathi esiphelele sokudluliswa kwesiginali yokulawula okufushane kwesisetshenziswa kufanele sibe ngaphansi kuka-2500us noma umjikelezo womsebenzi wesignali yokudlulisa isignali yesikhala esifushane akufanele yeqe u-10%.
3.3.3 5.8G Izidingo Zokugwema Ukuphazamiseka:
Kokubili ngemithetho emidala ne-CE, asikho isidingo sokugwema ukuphazamiseka kwe-5.8G, ngakho ukugwema ukuphazamiseka kwe-5.8G kubangela ubungozi obukhulu uma kuqhathaniswa ne-5.1G ne-2.4G wifi.
3.3.4 Izidingo zokugwema ukuphazamiseka kwe-Bluetooth (BT):
I-SRRC entsha idinga ukugwema ukuphazamiseka kokuhlolwa kwe-Bluetooth, futhi azikho izimo zokukhululwa (isitifiketi se-CE sidingeka kuphela kumandla angaphezu kuka-10dBm).
Okungenhla yikho konke okuqukethwe yimithetho emisha. Sithemba ukuthi wonke umuntu anganaka isikhathi sokuqinisekiswa kwezitifiketi zemikhiqizo yakhe kanye nomehluko ekuhlolweni komkhiqizo omusha ngesikhathi esifanele. Uma uneminye imibuzo mayelana nemithetho emisha, sicela ukhululeke ukuxhumana nganoma yisiphi isikhathi!
