Hangzhou Mobile and Huawei recently completed the joint aggregation site deployment pilot. This is the first time in the industry the latest Aggregation Site solution is used to deploy pole-mounted sites in batches, accelerating 4G+ site deployment.  

Aggregation site revolutionizing the network deployment mode and simplifying end sites

With the rapid growth of MBB technology, operators' network sites tend towards homogeneity. Hangzhou Mobile plans to deploy small-cell base stations to improve network capacity and deliver differentiated network experience, but runs into difficulty with site acquisition, power supply, and residential approval. The difficulty is expected to grow significantly during evolution to 4G+. 

In this pilot program, Hangzhou Mobile used the high-voltage DC (HVDC) remote power supply solution on its commercial network. With this solution, Hangzhou Mobile deployed power supply and backup devices at the aggregation site to supply HVDC power to pole-mounted end sites, improving power supply reliability of the live network. This solution uses the aggregation site to provide power supply and transmission resources to end sites and therefore exempts operators from seeking the approval for power supply and transmission for end sites, significantly expediting the deployment of pole-mounted sites in urban areas. 

The aggregation site deployment mode helps Hangzhou Mobile provide power supply to pole-mounted sites in urban areas, ensures stable power supply by using HVDC power to prevent voltage decreases, and reduces the battery purchase and O&M costs by means of centralized power backup. 

The 4G+ deployment pace is speeding up and the pole-mounted site is set to become the mainstream site form. As a breakthrough to traditional site deployment modes, the aggregation site solution simplifies end sites and meets space and decoration requirements for end sites, enabling mass rapid deployment of pole-mounted sites in urban areas.
