James E. Streed 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).

  • Methods for fade detection and fade recovery in a wireless communication system
    Patent number: 8644295
    Abstract: Methods are provided for fade protection at infrastructure equipment in a wireless communication network. The disclosed fade protection methods quantify signal quality, and based on the signal quality can detect fade conditions and/or recovery from such fade conditions. In one implementation, the disclosed fade protection methods can be implemented at Fixed Network Equipment (FNE) in an Association of Public-Safety Communications Officials (APCO) Project 25 (P25) compliant system.
    Type: Grant
    Filed: April 30, 2010
    Date of Patent: February 4, 2014
    Assignee: Motorola Solutions, Inc.
    Inventors: James E. Streed, Harish Natarahjan
  • Methods and apparatus for method for maintaining a radio link at a mobile radio
    Patent number: 8437334
    Abstract: Methods and apparatus are provided for radio link maintenance at a mobile radio in a wireless communication network. The disclosed methods and apparatus help a mobile radio maintain a radio link by regularly monitoring frame synchronization, regularly checking a scrambling sequence of a mobile radio against that of infrastructure equipment, and regularly detecting and/or recovering from fade conditions. In the event the radio link can not be maintained, then the disclosed methods and apparatus will cause the mobile radio to switch to a control channel so that the synchronization, scrambling mismatch and/or fade issues may be corrected. In one implementation, the disclosed methods and apparatus can be implemented at mobile radios in an Association of Public-Safety Communications Officials (APCO) Project 25 (P25) compliant system.
