Abstract: A spectrum access system (SAS) includes a transceiver that receives information indicating a path loss from an interior location to an exterior location in response to a base station being installed at the interior location. The SAS also includes a processor to determine an aggregate interference level for an incumbent proximate the exterior location based on the path loss. An edge router executes instances of a packet core network. The edge router instantiates containers for a connectivity or digital automation enabler and routes customer network traffic without leaving the customer network. A domain proxy receives a request to allocate carriers to a base station and determines whether a frequency separation between the carriers is larger than a bandwidth allocated to an incumbent. The request is rejected if the frequency separation is less than the bandwidth and granted if the frequency separation is greater than or equal to the bandwidth.

Abstract: An apparatus such as a domain proxy implemented in an edge cloud of a private enterprise network includes a processor configured to aggregate traffic for Citizens Broadband radio Service Devices (CBSDs) in a private enterprise network. The apparatus also includes a transceiver configured to monitor communication with geo-redundant instances of a spectrum access system (SAS) that allocate frequency bands in a shared spectrum to the CBSDs. The processor is configured to instantiate a local SAS in response to the geo-redundant instances of the SAS becoming unavailable. The local SAS is configured to respond to heartbeat messages from the CBSDs. The local SAS is also configured to attempt to establish a connection with an environmental sensing capability (ESC) in response to the geo-redundant SASs becoming unavailable.
