In 2020, which marked the beginning of large-scale construction of 5G networks, over 700,000 outdoor 5G base stations have been deployed nationwide, while indoor 5G network coverage is still in its early stages. Considering the significant amount of traditional Distributed Antenna Systems (DAS) built during the 4G era, the current solutions are as follows:
Simple combining: This approach involves directly feeding the existing passive DAS system with a two-channel indoor device to quickly achieve coverage. However, since most traditional DAS distribution systems are single-channel scenarios (with 75% of indoor DAS in Guangdong being single-channel), this method can only provide a single-stream 5G signal, resulting in network speeds of around 300 Mbps at best, which leads to a poor user experience.
Building an additional DAS distribution system: This solution involves constructing an additional channel on top of the existing traditional single-channel DAS distribution system to achieve dual-channel distribution. However, implementing this approach requires installing new feeder lines along the existing ones, which presents challenges such as coordination with property management and high construction costs, as most of the distribution systems are already concealed in ceilings.
5G wired frequency migration solution: This solution involves replacing the power splitters, couplers, antennas, and feeders in the existing distribution system to support DC power feeding. It requires a comprehensive inspection of the existing distribution system. Failure to conduct a thorough inspection of passive components may result in overvoltage short circuits in the distribution system, leading to breakdowns in the frequency migration devices. This approach is difficult to implement, poses safety risks, involves complex coordination with property management, and requires the replacement of multiple components.
Compared to existing technologies, our product offers the following innovations and advantages:
Minimalistic transformation: Minimal modifications are made only at the combiner location.
Multi-stream coverage: A single feeder line can support up to four 5G coverage streams.
Convenient installation, plug-and-play, and flexible deployment: It allows selective implementation of multi-stream coverage in specific indoor areas or comprehensive coverage, providing differentiated services.
Cost advantages: For a property area of 50,000 square meters, adding an additional traditional DAS route is estimated to cost 200,000 yuan. By using the 5G booster solution, the cost can be controlled within 60,000 to 80,000 yuan, saving over 60% of the investment.
