H3C RA5000 Router Series
As the fifth generation mobile communication network, 5G network is the extension and development of 4G mobile communication network. It has the following characteristics:

• High-speed: The maximum downlink bandwidth of the network can reach 10 Gbps, which is 50-100 times as much as that of the 4G network. It can fully meet the needs of high-resolution media transmission such as 4K and VR, making it possible for more immersive live VR broadcasting.
• Large capacity: Due to the introduction of high-frequency spectrum resources and the support of large-scale MIMO technology, the capacity of 5G network will increase times compared with the present cases, which means that base stations can provide services for more terminals at the same time to meet the requirements of future high-density Internet of Things terminal access scenarios.
• Low latency: 5G network has a delay as low as 1 millisecond. Lower latency means more timely response, which is significant for unmanned driving, emergency accident handling, industrial production control and other scenarios.

In order to meet the needs of 5G network with high speed, large capacity and low latency, H3C customizes IPRAN RA5000 series of high performance integrated access routers for 5G network return scenario to meet the sustainable development needs of operators and dedicated network of large enterprise, to help operators improve network bandwidth and deployment efficiency, and to reduce operation and maintenance costs.
