5G-ready Transport

What is required for transport in 5G era?

Significant architecture changes may not be required for Transport Network unlike the RAN where massive evolution is required.
However, as a variety of people and things are being connected including IOT devices, and traffic demands are becoming diversified, the required function of Transport network is also diversified and much higher network performance than 4G is required in all aspects.

Service Providers need to address the following challenges for deployment of 5G-reday transport network.
・Flexible and efficient network expansion form 4G to 5G, whilst minimizing deployment cost
・Selecting the best network architecture, topology and product with coexistence of legacy network 
・Avoiding complicated network operation and management

NEC is supporting deployment of 5G-ready transport network efficiently and effectively, with the combination of Global partners’ products and NEC’s own products as an Open Ecosystem in accordance with customers’ demand and requirement, covering network design, technical support and operation through our rich experience with telecom operators in Japan and the global market.

What do we need to do for efficient deployment of 5G-ready transport network?

The investment on current network should not be wasted and be utilized for 5G as well. Simplification of network is mandatory to balance the continuous expansion of network and deployment of 5G-ready network. Simple network architecture is important to accommodate various use cases quickly and easily.

Variety of components to adapt various use cases and integrated management system to monitor such components are also the keys to a successful deployment. NEC deploys the multi-domain and multi-layer network with the best of breed components selected from global partners’ products, and provides E2E network management to enable integrated operation and management of diversified components. Further, this can be connected to the orchestrator in the future, to enable an automated and efficient network operation.

NEC enables 5G-ready network deployment by lowering CAPEX with network simplification, and also reducing OPEX with integrated monitoring of multiple components and automated operation.

Use case of 5G-ready network migration

The picture shows an use case of 5G-ready network migration.

NEC has its own product of front haul solution as hardware supplier in addition to a role as SIer enabling an Open Ecosystem.

NEC has the capability of consulting for migration scenario designs and best of breed proposals based on customers’ requirement through its rich experience and technical expertise as hardware supplier.

In this use case, NEC realizes network migration scenario with simplification of the network by using WDM Filter and SFP type module, and minimizing the number of nodes. This also enables capabilities to easily increase the bandwidth in future.
