Patent number: 9088388Abstract: The high quality PCS communications are enabled in environments where adjacent PCS service bands operate with out-of-band harmonics that would otherwise interfere with the system's operation. The highly bandwidth-efficient communications method combines a form of time division duplex (TDD), frequency division duplex (FDD), time division multiple access (TDMA), orthogonal frequency division multiplexing (OFDM), spatial diversity, and polarization diversity in various unique combinations. The method provides excellent fade resistance. The method enables changing a user's available bandwidth on demand by assigning additional TDMA slots during the user's session.Type: GrantFiled: April 7, 2014Date of Patent: July 21, 2015Assignee: AT&T Mobility II LLCInventors: Siavash Alamouti, Eduardo F. Casas, Michael Hirano, Elliott Hoole, Mary Jesse, David G. Michelson, Patrick Poon, Gregory J. Veintimilla, Hongliang Zhang

Patent number: 7765599Abstract: Embodiments of multimedia transmitters, receivers and methods for communicating multimedia content in a wireless network are generally described herein. Other embodiments may be described and claimed. In some embodiments, a checksum is generated by decoding the multimedia content to respond to queries from a multimedia content source within a predetermined time period, a propagation delay associated with the wireless multimedia link is determined, and transmission of the multimedia content over the wireless multimedia link is inhibited when a response from the multimedia receiver exceeds a propagation delay by a predetermined time period.Type: GrantFiled: August 8, 2006Date of Patent: July 27, 2010Assignee: Intel CorporationInventors: Eduardo F. Casas, Gregory Peek
