Systems, devices, and techniques described herein are directed to improved wireless handovers based on device movement. User equipment (UE) can be wirelessly connected to a network via a serving cell, while handover operations allow the UE to transition a connection from the serving cell to a candidate cell to facilitate mobility and connection continuity. In some cases, the serving cell can be a wide area network and the candidate cell can be a small cell, whereby the small cell utilizes millimeter wavelength communications. In some cases, where a candidate cell can provide a higher quality connection compared to the serving cell, a handover decision can be based at least in part on motion data associated with the UE. For example, if a speed of the UE is above a threshold, the UE or network can be prevented from initiating a handover from the serving cell to the candidate cell.
