I-China Kingtone B2 + B5 isandisi sophawu lwe-4g ibhendi ebini 850/1900 gsm iipcs 2g 3g iphinda-phinda amandla elanga 5W, 10W, 20W cdma iipcs zeselfowuni i-booster yefowuni yenzelwe ukusombulula iingxaki ze-wak yesiginali yeselula, enexabiso eliphantsi kunokongeza isikhululo esitsha. (BTS).Umsebenzi ongundoqo wabaphindayo kukufumana umqondiso wamandla asezantsi ukusuka kwi-BTS ngokusasazwa kwe-RF kwaye emva koko udlulise umqondiso owandisiweyo kwiindawo apho unxibelelwano lwenethiwekhi lunganelanga. Kwaye isignali ehambayo nayo iyandiswa kwaye idluliselwe kwi-BTS nge- icala elichaseneyo.
Inkqubo Apple: call : *3001#12345#* ,amandla omqondiso uya kubonisa kwikona ephezulu ekhohlo.
Inkqubo yeSamsung : fowuna : *#0011#
Okanye unokukhuphela "LTE Discovery" app ukujonga.
Beka ifowuni yakho apho ukujonga ukomelela kwayo komqondiso ngaphandle:
Android : useto→ malunga nefowuni→imo→inethiwekhi ,umboniso wedbm uzakuba ku -75dbm ukuya ku -85dbm ngeenxa zonke ;
Iifrikhwensi eziManyeneyo ezenzelwe wena kwireferensi yakho, khetha iibhendi ezi-2:
I-B1 (2100) yi-Band 1 kwi-2100 MHz.
I-B2 (1900) yi-Band 2 kwi-1900 MHz.
I-B3 (1800) yi-Band 3 kwi-1800 MHz.
I-B4 (AWS) yibhendi 4 kwi-AWS 1700/2100MHz.
B5 (850) i band 5 on 850 MHz.
I-B7 (2600) yi-Band 7 kwi-2600 MHz.
I-B8 (900) yi-Band 8 kwi-900 MHz.
I-B20 (800) yi-Band20 kwi-800MHz
