Patent number: 10957968Abstract: 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.Type: GrantFiled: November 20, 2018Date of Patent: March 23, 2021Assignee: Motorola Mobility LLCInventors: Md Rashidul Islam, Mohammed R.

Publication number: 20200192442Abstract: A communication device, method, and computer program product monito, by a controller, respective temperatures of two or more antennas of the communication device. A first antenna of the two or more antennas has a first temperature. A modem of the communication device transmits data to the first antenna. The controller compares each of the respective temperatures to a corresponding temperature threshold. In response to determining that the first temperature exceeds the temperature threshold, the controller determines whether at least one second antenna of the two or more antennas has an associated second temperature that is less than a corresponding second temperature threshold. In response to determining that at least one second antenna has a second temperature that is less than the corresponding second temperature threshold, the controller selects a second antenna from among the at least one second antenna and switches data transmission to the selected second antenna.Type: ApplicationFiled: December 13, 2018Publication date: June 18, 2020Inventors: MD RASHIDUL ISLAM, HUGH K.
