5G Fronthaul Network Testing Considerations

This White Paper explains why Ethernet impairment testing is crucial in deploying 5G fronthaul networks, and highlights the protocols that need particular attention when optimizing your equipment or application performance in 5G fronthaul networks.

5G networks offer lower latency, greater flexibility, and increased bandwidth compared to 4G technology. To deliver these improvements, 5G fronthaul networks use different hardware and networking protocols to those found in previous generation networks.

While this technology shift delivers more versatile, scalable, and cost-effective networks, moving away from circuit switched networks or leased lines means 5G fronthaul networks are now subject to Ethernet impairments at the packet level.

Network Equipment Manufacturers (NEMs), Network Infrastructure Providers (NIPs) and Service Providers (SPs) responsible for 5G fronthaul networks will need a way to test how their equipment and applications cope with these network impairments if they want to offer an optimal user experience. We believe that the best way to assure this is to test rigorously in the lab—before the network is deployed.

In this white paper, we’ll look at why Ethernet impairment testing is crucial in developing, testing, and deploying successful 5G fronthaul networks. We’ll also highlight the protocols that need particular attention and offer advice on what to consider when optimizing your equipment or application performance in 5G fronthaul networks.
