Solution Brief

UPF Offload with Truminds and Kontron
Enterprises with a need for highly-reliable, business-critical mobile communications are increasingly adopting private cellular networks in preference to public cellular or WiFi alternatives. In order for these networks to be cost-effective, it’s important for them to maximize the number of client devices that can be supported in a small-footprint server. Thus, by leveraging Napatech’s SmartNIC-based UPF offload solution running on an edge server from Kontron, Truminds has op- timized the cost-performance of their private cellular network infrastructure for markets like healthcare, government offices, utilities, universities and airports.
