VLG frequency shift 5G indoor coverage solution

In response to the current situation of 5G indoor coverage, such as high construction cost, low investment return rate, long construction period, and poor 5G quality due to the inability to implement MIMO, VLG has developed an innovative solution VLG-MIMO + 5G frequency shift indoor coverage system. Based on the single RF cable of the traditional DAS system, the system uses frequency shift technology to achieve 5G MIMO coverage of single cable 2T2R and dual cables 4T4R. It has the advantages of high transmission rate, network management, support for dynamic adjustment of power balance, low construction cost, simple construction, low operating cost, and seamless compatibility with the original 2G/3G/4G network.
