Traditionally, that was the case. However, telcos are now moving toward Open RAN as an alternative to building their RAN networks on purpose-built hardware such as baseband units for 5G, and instead moving to a disaggregated, open radio access network. These ORAN networks are built on containerized platforms, primarily. So, we're moving away from traditional, dedicated NEP hardware to x86 machines running Kubernetes - something a lot more people than 4G/5G phreakers are familiar with.
