Professional Accurate Prompt Reliable

600MHz NR 4T4R RRU




Product Overview

In the telecom operators and telecom equipment manufacturers to work together, covering a wide range of 5G networks continue to rapidly expand.In the future, with the development of 5G network construction to- wards hierarchical and refined development, a large number of flexible and open 5G network construction methods need to be used to enhance 5G network coverage. Based on this demand, FCST Co.,Ltd. independently designed and developed a FCST 5G NR base station.FCST 5G NR follow 3GPP 5G NR station air interface standard protocol development, tissue compliance ORAN open networking architecture definition, is connected to the support via eCPRI DU interface, L1 / LOW PHY (Split Option 7-2) data processing.FCST 5G NR base station is designed for outdoor environments, for enhancing the multichannel 5G network coverage in outdoor scenes, high-power, high-performance base station products. This base station product can be widely used in outdoor wide-area coverage scenarios featuring high traffic density, high connection number and high mobility.
