Tetra 380MHz Band Yiyan 380-385 MHZ 390-395 MHZ Ona Meji Redio UHF Ita gbangba ifihan agbara Atunse Ampilifaya pẹlu RJ45
Iwọn igbohunsafẹfẹ 380-385 MHz (uplink) / 390-395 MHz (downlink) jẹ apẹrẹ lati yanju awọn iṣoro ti ifihan agbara alagbeka alailagbara, eyiti o din owo pupọ ju fifi Ibusọ Base tuntun kan (BTS).Iṣe akọkọ ti RF Bi-Directional Amplifiers eto ni lati gba ifihan agbara kekere lati BTS nipasẹ gbigbe igbohunsafẹfẹ redio ati lẹhinna atagba ifihan agbara si awọn agbegbe nibiti agbegbe nẹtiwọọki ko pe.Ati pe ifihan agbara alagbeka tun pọ si ati gbigbe si BTS nipasẹ itọsọna idakeji.
Awọn ifojusi ọja:
● Pẹlu apẹrẹ modularized, rọrun fun itọju
● Software ibojuwo latọna jijin (ibudo tẹlentẹle), rọrun funitọju ati isakoso.
● IP55 eruku & omi, pẹlu awọn ibeere kekere lori ayika fifi sori;
● Pẹlu ampilifaya agbara ila-giga ati ijusile duplexer giga, ti o lagbara lati kọ intermodulation ati awọn ifihan agbara spurious
