The transport infrastructure of your network is key in securing the best 5G performance. The radio evolution, introducing new interfaces and deployment architectures, drives the need for increased capacity and connectivity, lower latency, and support for increased traffic volume in 5G IP networks. Also, the densification of radio sites, as well as new radio interfaces, drive the need for higher port density of high capacity interfaces in backhaul routers. Our Router 6000 family is designed to cater for the diverse challenging demands of modern backhaul and fronthaul networks.
Building efficient fronthaul networks using packet technologies
With 5G we see more operators exploring the possibility to centralize their networks and build packet-based fronthaul systems. But by doing this, there is also a need to handle the legacy CPRI flows to enable a packet-only network: Ericsson’s new Router 6673 is designed to fulfill those customer needs.
Centralization can add benefits to the operator but to leverage those benefits, a cost-efficient fronthaul network is key. The road to a positive business case includes handling of several implications when building the fronthaul network:
- High-capacity demands
- Critical sync distribution
- Supporting RAN evolution
- Network maintenance and installations
- Strict latency requirements
- Network reliability
But to address these challenges, there are several technology choices to consider. Let us focus on the two alternatives ways to handle CPRI in a packet-based network:
- Mapping the CPRI frames into ethernet packets, called Radio over Ethernet (RoE)
- Convert the CPRI streams into eCPRI by baseband processing
The two alternatives have their set of benefits, where conversion being the most effective technology in terms of bandwidth savings - 60-80% savings can be achieved depending on RAN configuration and by that, reducing the fiber needs as well as transport equipment.
The new Router 6673 supports RoE and Conversion in the same platform, offering full support across all current and future Ericsson radios and CPRI and eCPRI variations. It also works as a cell site router and aggregates enterprise traffic.
Router 6000 series
The Router 6000 series responds directly to service providers’ challenges of the capabilities that 5G requires in IP backhaul/fronthaul/ aggregation to support the exponential traffic growth, increased network connectivity, the need for synchronization and security in a complete, scalable, and cost-efficient router portfolio.
The diverse Router 6000 portfolio offers a variety of products that can be used from small sites to big aggregation sites. The modularity and flexibility of the portfolio supports any network size, even as the scale of the network grows. Any deployment need is supported, indoors as well as outdoors.
