  Edge computing that leverages cloud resources to the proximity of user
devices is seen as the future infrastructure for distributed applications.
However, developing and deploying edge applications, that rely on cellular
networks, is burdensome. Such network infrastructures are often based on
proprietary components, each with unique programming abstractions and
interfaces. To facilitate straightforward deployment of edge applications, we
introduce OSS based RAN on OTA commercial spectrum with DevOps capabilities.
OSS allows software modifications and integrations of the system components,
e.g., EPC and edge hosts running applications, required for new data pipelines
and optimizations not addressed in standardization. Such an OSS infrastructure
enables further research and prototyping of novel end-user applications in an
environment familiar to software engineers without telecommunications
background. We evaluated the presented infrastructure with E2E OTA testing,
resulting in 7.5MB/s throughput and latency of 21ms, which shows that the
presented infrastructure provides low latency for edge applications.
