Network testing firm Ookla, which collects data from consumers via their popular broadband Speedtest.net website and App, has teamed-up with communications technology developer Ericsson to demonstrate an “innovative solution allowing users to measure and validate 5G network slicing performance” via the same app.

Network slicing is a feature of the latest end-to-end 5G Standalone (aka – 5G+ / 5G Advanced) based mobile broadband networks. The feature essentially allows for multiple virtual network slices across the same physical network. Each slice is isolated from other network traffic to give dedicated performance, with the features of the slice typically being tailored to specific use case requirements (online gaming, enhanced mobile broadband, payment processing at big events etc.).

NOTE: Ofcom recently reported (here) that 5GSA networks are now available to 83% of areas outside of premises in the UK, falling to 47%-65% when looking at it as a range across different mobile operators. The government, for its part, retains an ambition “for all populated areas” to have access to 5GSA based mobile broadband by 2030.

However, until now there hasn’t really been much in the way of independent solutions for validating the Quality of Experience (QoE) that users (consumers and service providers) see when harnessing Network Slicing, which is necessary given how Service Level Agreements (SLA) may apply to such services. Ookla and Ericsson have thus developed a methodology that enables their Speedtest app to identify and test specific network slices in real-time.

Tibor Rathonyi, Senior Advisor at Ookla, said:

“Network slicing is no longer a future concept; it is a commercial reality. However, you cannot manage what you cannot measure. Our work with Ericsson is a pivotal first step in providing the transparency needed to prove the value of these premium 5G services to both consumers and enterprises.”

The results of this collaboration will debut during Mobile World Congress (MWC) Barcelona 2026. Attendees will be able to visit the Ericsson pavilion, in Hall 2, to experience a live demonstration of a specialized test version of the Speedtest® app, featuring:

➤ Side-by-Side Comparison: Visualizing the performance gap between a standard 5G connection and a service-specific slice within Ericsson’s live 5G network at the venue.

➤ SLA Verification: Real-time reporting on Key Performance Indicators (KPIs) within a dedicated slice to prove guaranteed quality of service.
