China 2 watt/5 watt/10 watt/20 watt 900 2100 band ezimbini cell phone repeater/repetidor/booster/amplifier yangaphandle nangaphakathi yenzelwe ukusombulula iingxaki zewak mobile signal, 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.
Iimbonakalo:
1,Amandla okuPhuma +30dBm – +43dBm kwisicelo esikhulu sokhuselo;
2, Inzuzo ephezulu yokusebenza njengoMn.95dB;
3, Ukwamkela isihluzi esinokukhetha kakhulu kunye nelahleko ephantsi yokufaka isusa ukuphazamiseka phakathi kwe-uplink kunye ne-downlink;
I-4, izibuko ze-RS232 zibonelela ngamakhonkco kwi-laptop yokuseta kwendawo kunye nokubeka iliso ngojongano lwewebhu eyakhelwe-ngaphakathi;
I-5, imodem eyakhelwe-ngaphakathi engenazingcingo (Ukhetho) ukujonga kude ngeSMS okanye ngeGPRS;
I-6, iiparamitha eziphindaphindayo kunye nobume bunokubekwa esweni yiPhaneli yoLawulo, njengobushushu, inqanaba lamandla emveliso, inzuzo, i-ATT, ilahleko yokubuya, iVSWR njl.
7,Inkxaso yokuphucula i-firmware ukude ngeGPRS;
I-8, ubuchule bokukhulisa amandla obukumgangatho ophezulu kunye nokusebenza okuthembekileyo;
9, Ubungakanani obuncinci kunye nobunzima obulula, kulula ukuyifaka eludongeni okanye kwipali;
