Abstract: The described technology is generally directed towards citizens' broadband radio service (CBRS) channel selection for cellular communication networks in a manner that reduces the risk of CBRS channel revocation due to incumbent activity within a dynamic protection area. A data store can be maintained that includes dynamic protection area location information as well as historic incumbent CBRS channel use information. When selecting a CBRS channel for a radio access network (RAN) node, the position of the RAN node can be considered to determine if the RAN node is in or near a dynamic protection area. If so, the data store can be consulted to avoid selecting CBRS channels that have historically been subject to revocation in the dynamic protection area.

Abstract: Techniques for selecting a wireless connection based on network metrics are discussed herein. For example, user equipment (UE) can be connected to a Wi-Fi network. The UE may test the Wi-Fi connection to determine metrics associated with the Wi-fi connection. The UE may compare the metrics to a speed and/or bandwidth threshold. If the Wi-fi connection speed is below a threshold, the UE may determine metrics associated with a cellular connection to determine whether to switch to a different cellular connection. If a first metric of the candidate cellular connection is above a threshold (e.g., a power level threshold), the UE can determine a speed or bandwidth of the connection. If the speed or bandwidth is above a threshold, the UE can attach to the cellular connection and can send and/or receive data using the newly established connection.
