Mohammed N. Smadi has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 8837509
    Abstract: Techniques in a mobile communication device for communicating with a wireless access point (AP) are described. The mobile device receives from the AP data which indicate a plurality of activated service intervals in the superframe that are made available to mobile devices for communication access. The mobile device attempts to access, during the indicated activated service intervals, a radio medium via the AP. The mobile device refrains from attempting to access the radio medium via the AP during each power conservation interval provided in between the indicated activated service intervals.
    Type: Grant
    Filed: May 2, 2012
    Date of Patent: September 16, 2014
    Assignee: McMaster University

  • Patent number: 8194576
    Abstract: Methods and apparatus for controlling a wireless access point (AP) (e.g. a battery-powered wireless AP) for reduced power consumption are provided. In one illustrative example, the AP is adapted to provide communication access for end stations in one or more activated service intervals of each superframe. During operation, the AP changes the number of activated service intervals that are available to end stations for the communication access, as well as the durations of their active subinterval durations, in accordance with a change in traffic requirements. The AP regularly broadcasts data which indicates the activated service intervals that are made available to the mobile devices. A wireless transceiver of the AP is enabled during each activated service interval made available to the mobile devices, but the AP is placed in a power conservation mode during each deactivated service interval provided in between the activated service intervals.

  • Publication number: 20110085533
    Abstract: A wireless access point supports data rates and advertises an indication of a minimum data rate for advertisement. Those of the supported data rates that are less than the minimum data rate for advertisement are reserved for limited use. A mobile station that requests to communicate with the wireless access point at one of the one or more supported data rates that are reserved for limited use is informed by the wireless access point how much time communications with the wireless access point at one or more of the one or more supported data rates reserved for limited use will be permitted.

  • Patent number: 7873017
    Abstract: A wireless access point advertises data rates that it supports. A mobile station is permitted to communicate with the access point at one or more of the lower data rates only if the mobile station satisfies one or more conditions.
