The estimation of location can be based on one or more location signatures that include information of the wireless display device(s). The location estimation method can include identifying available access points (APs) and wireless display adapters, determining wireless characteristics of the available APs and wireless display adapters, calculating match scores based on the wireless characteristics of the available APs and the wireless characteristics of the available wireless display adapters, determining a location signature based on the determined match scores, and determining a location based on the location signature. The communication device can be configured to automatically connect to the wireless display device(s). The communication device can operate in a standby display mode upon the connection. ## Claims ### Claim 1 A location estimation method to assist a communication device to establish a wireless display connection, comprising: identifying, by the communication device, one or more available access points (APs) and one or more available wireless display adapters;
