Method for Dual-path Upgrade in a Leaked Signal Indoor Distribution System in 5G Network

Traditional indoor distribution systems in 2G, 3G, and 4G networks are mostly single-path, but the indoor distribution systems in 5G networks require dual paths to get greater capacity by space division multiplex. This document describes the reconstruction from a traditional single-path indoor distribution system to a dual-path indoor distribution system on a 5G network. Suitable scenarios need to be found in which the engineering workload is small and the cost is low, and in the scenario, a key point is that one path in the dual-path indoor distribution system would be leaked signals from nearby floors. If the level of the leaked signal is too low and the signal quality is poor, only low-order modulation modes can be used. Even if dual-stream access is provided, the download rate cannot be improved. The download rate is even lower than that of a single-path indoor distributed system. The suitable sicario in which leaked signal can support RANK 2 is discussed in the paper that 5G users can get higher throughput in the dual path upgrade indoor distribution system.
