27dBm Lte & Wcdma 18002100MHz 2G 3G 4G ALC Dual-Band Signal Extender Amplifier Lte Mobile Network Repeater Cell Phone Signal Booster inonyanya kushandiswa kubatsira cellular Base Station (BTS) kana Repeaters kugadzirisa indoor sign bofu nzvimbo, basa rayo rinonyanya kubhadhara kurasikirwa kwesystem kubva mukati- chivakwa chekugovera tambo, kupatsanura simba uye inotungamira coupler, uye kuwedzera mukati-yekuvaka chiratidzo chekuvhara, uye kuvandudza kuchinjika kwemukati-yekuvaka chiratidzo chekuvhara dhizaini dhizaini kuti isangane nekusimba kwemunda zvinodiwa zvemukati-yekuvaka chiratidzo chekuvhara system.
Dual band repeater Features:
1.Customized 2-bhendi frequencies, senge 900/1800MHz, 900/2100MHz, 900/2600MHz, 1800/2100MHz, 1800/2600MHz, 2100/2600MHz, 850/1900MHz zvichingodaro kusangana neakasiyana network masaini chikumbiro;
2.NeMGC basa, (Manual Gain Control), Mutengi anogona kugadzirisa Gain sezvinodiwa;
3.NeDL chiratidzo che LED kuratidza, kubatsira kuisa antenna yekunze panzvimbo yakanakisisa;
4.Ne AGC uye ALC, ita kuti repeater ishande yakagadzikana.
5.PCB ine basa rekuzviparadzanisa nevamwe, ita kuti UL uye DL chiratidzo chisafurirane,
6.Low intermodulation, yakakwirira Gain, yakagadzikana Output simba
