The detachable antenna comprises: an electrically insulating base; a main antenna and a first antenna element, at the base, respectively operable at independent first and second given frequencies. The device further comprises: a memory associating the first and second given frequencies; an antenna port configured to detachably receive the base of the detachable antenna; a second antenna element, at the antenna port, operable to wirelessly interact with the first antenna element when the base of the detachable antenna is received at the antenna port; a circuit configured to detect wireless interactions between the second antenna element and the first antenna element; and a controller configured to: select the first given frequency using the second given frequency, as detected via the circuit; and, thereafter wirelessly communicate via the main antenna operated at the first given frequency.

A method, wireless communication device (WCD), and computer program product deploys an additional, retractable antenna to enhance signal communication within an identified network. A processor executes an antenna deployment module (ADM) in order to determine a link status based on a quality and/or a strength of communication signals propagated via at least one stationary antenna. In response to the link status indicating that coverage of a second/target network is available or that a quality of a signal propagated within a first network is less than a threshold level, the ADM provides a deployment signal to a deployment component. In response to receiving the deployment signal, the deployment component deploys the retractable antenna by extending the retractable antenna from a stowed position to a deployed position. The ADM enables the WCD to communicate within the selected network via the deployed retractable antenna using a higher quality communication signal.

This invention provides a wireless transceiver device for retrofit conversion of non-wireless enabled electronic controllers and controlled host devices. This invention allows for the rotating of the wireless transceiver device allowing for the entire device to rotate around the connector axis. This functionality allows for the ability to rotate the wireless transceiver device 360 degrees or to any orientation that maximizes the available space around the host device or around the area of permanent or temporary installations of networks of single or multiple controllers and controlled devices. The inclusion of a stop pin washer plate may be combined with a rotation limiting washer to prevent the rotating assembly from moving freely around the 360 degrees of rotation.
