Performance when it matters the most

IP elevating 5G performance

Packet fronthaul

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.

What is the future of the 5G cell site router?

As we continue to deploy 5G, we are engaging in even more specific dialogue with Service Providers about how they need to evolve their transport network for 5G. But when planning your network deployment, how much routing functionality will be needed at a 5G cell site?

5G is all in the timing

As RAN networks upgrade with LTE Advanced technologies and 5G, transport planners face unprecedented challenges in a new reality where it’s essential to manage multiple timing sources across the network.

How to ensure emerging RAN requirements are actually supported by transport

Operators are rolling out many new tricks to get more capacity into their networks – Massive MIMO, Licensed Access Assist (LAA), higher order carrier aggregation, and Coordinated Multipoint (CoMP). With 5G will come even more advanced spectrum sharing techniques. What all these techniques have in common is the need for new basebands, and much more demanding coordination between basebands.

5G network timing and synchronization (T&S) challenges

5G’s wide use of TDD spectrum – along with new LTE-A and 5G features dependent on right time and phase synchronization – drives a need for service providers to rethink sync solutions. Robust timing is more than just putting GNSS/GPS everywhere. What are the key T&S challenges that 5G presents, and what new timing protocols are required? What standards and solutions are evolving for 5G transport? How can operators implement these requirements within new RAN architectures?
