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.

Technical features

1. VLG-MIMO+5G frequency shift indoor coverage system: Based on the single RF cable of the traditional DAS system, it provides a 5G MIMO solution, which can realize 2T2R with a single cable and 4T4R with two cables.
2. High transmission rate and network manageability: The system has the characteristics of high transmission rate and network manageability, and supports dynamic adjustment of power balance.
3. Low construction cost and simple construction: Compared with other solutions, this solution has low construction cost, simple construction, low operating cost, and seamless compatibility with the original 2G/3G/4G network.
4. Using frequency shift technology: Realize 2T2R signal transmission in one cable, and combine the two signals through frequency shift and combining technology to improve signal transmission efficiency.

Technical features

5. Intelligent power compensation algorithm: Adopt intelligent power compensation algorithm to solve the power loss problem, ensure that the antenna output power reaches the standard value, and ensure the best transmission rate.
6. Dynamic power balance algorithm: The system’s unique power automatic balance algorithm monitors and automatically balances the power of the two NR channels to improve the network rate.
7. Real-time monitoring and management: The antenna can be managed and controlled, and all parameters can be monitored in real time, including output power detection, abnormal alarm, offline detection, etc.
