This disclosure describes wireless communication techniques, protocols, methods, and devices applicable to a docking system environment in which aspects of wireless docking may function using vicinity-based undocking techniques. In some examples, the techniques of this disclosure enable a wireless docking center to undock a wireless dockee in a situation where a wireless dockee moves out of the vicinity of a wireless docking center so as to prevent malicious users from using peripheral devices available through the wireless docking center to interact with the wireless dockee without the wireless dockee user's knowledge. In other examples, the wireless dockee may undock itself from a wireless docking center when the wireless dockee moves out of the vicinity of a wireless docking center.
