Getting Started with Aether

Aether OnRamp is now the recommended way to get started with Aether. It defines a step-by-step procedure for deploying and operating Aether on your own hardware, including support for 5G small cell radios.

Other Aether guides available on this site include:

Note that Aether was originally deployed as a centrally-managed, ONF-operated cloud service, with the expectation that organizations would participate in Aether by connecting their edge site to this operational deployment.[1] That service has now been deprecated in favor of users bringing up their own Aether sites using OnRamp.

Aether Components

Aether builds on two main subsystems: SD-Core (a cloud native Mobile Core) and SD-RAN (an O-RAN compliant, software-based RAN). Additional documentation for each is available at:

More information about 5G and Aether's architecture can be found in the Private 5G: A Systems Approach book.
