3.2 DFS yahluke kancinane
Isixhobo sothumelo esingenazingcingo kufuneka samkele iteknoloji yothintelo lophazamiseko lweDynamic Frequency Selection (DFS), ekufuneka itshintshwe ibe ayinakho ukusetwa kunye nenketho yokucima iDFS.
Ukongezwa kwezixhobo zothumelo ezingenazingcingo kufuneka zamkele iteknoloji yokucinezela i-Transmission Power Control (TPC), kunye noluhlu lwe-TPC olungekho ngaphantsi kwe-6dB; Ukuba akukho msebenzi we-TPC, amandla emitha ye-omnidirectional elinganayo kunye nomda olinganayo we-omnidirectional radiation amandla okubonwa komda wokujongwa kufuneka uncitshiswe nge-3dB.
3.3 Ukwandisa uvavanyo lokuphepha ukuphazamiseka
Indlela yokumisela ukuthintela ukuphazamiseka ngokusisiseko ihambelana neemfuno eziguquguqukayo zesatifikethi seCE.
3.3.1 2.4G iimfuno zokuthintela ukuphazamiseka:
①Xa kufunyaniswe ukuba i-frequency ihlaziywe, ukuhanjiswa akufuneki kuqhubeleke kweso siqhagamshelanisi, kwaye ixesha lokuhlala akufanele lidlule kwi-13ms. Oko kukuthi, usasazo kufuneka lupheliswe ngexesha elithathwa ngumjelo.
② Isixhobo sinokugcina ukuhanjiswa kwesignali emfutshane yokulawula, kodwa umjikelo womsebenzi wesiginali kufuneka ube ngaphantsi okanye ulingane ne-10%.
3.3.2 Iimfuno zokuthintela ukuphazamiseka kwe-5G:
①Xa kufunyaniswe ukuba kukho isiginali ene-frequency yosetyenziso ephezulu kunomda wokubhaqa, ukuhanjiswa kufuneka kumiswe kwangoko, kwaye elona xesha liphezulu lokuhlala kwesiteshi yi-20ms.
② Ngexesha lokuphononongwa kwe-50ms, inani lokuhanjiswa komqondiso wolawulo olufutshane kufuneka libe ngaphantsi okanye lilingane namaxesha angama-50, kwaye ngeli xesha lokuqwalaselwa ngasentla, ixesha elipheleleyo lokuhanjiswa komqondiso omfutshane wesixhobo kufuneka libe ngaphantsi kwe-2500us okanye Umjikelo womsebenzi wesithuba esifutshane somqondiso wokuhambisa umqondiso kufuneka ungadluli kwi-10%.
3.3.3 5.8G IiMfuno zoThintelo loThintelo:
Zomibini ngemimiselo yakudala kunye ne-CE, akukho mfuneko yokuphepha ukuphazamiseka kwe-5.8G, ngoko ukuphepha ukuphazamiseka kwe-5.8G kubangela ingozi enkulu xa kuthelekiswa ne-5.1G kunye ne-2.4G wifi.
3.3.4 Iimfuno zokuthintela ukuphazamiseka kweBluetooth (BT):
I-SRRC entsha idinga ukuphepha ukuphazamiseka kokuvavanya kweBluetooth, kwaye akukho miqathango yokukhululwa (isiqinisekiso se-CE sifuneka kuphela kumandla amakhulu kune-10dBm).
Oku kungasentla kukho konke okubhalwe kwimimiselo emitsha. Siyathemba ukuba wonke umntu unokunikela ingqalelo kwixesha lokuqinisekiswa kwesiqinisekiso seemveliso zabo kunye nomahluko kuvavanyo lwemveliso entsha ngexesha elifanelekileyo. Ukuba unayo nayiphi na eminye imibuzo malunga nemimiselo emitsha, nceda uzive ukhululekile ukudibana nangaliphi na ixesha!
