Patent number: 10014977Abstract: A system and method for transmitting data over a channel, in which the data are categorized in at least two different categories. For example, the data are categorized according to the effect on perceived degradation on the data when error mitigation is performed on the data. Corrupted data of the first category are replaced using a first replacement method, such as retransmission and forward error correction. The corrupted data of the second category are replaced using a second replacement method different from the first replacement method, e.g., error mitigation or interpolation.Type: GrantFiled: September 21, 2015Date of Patent: July 3, 2018Assignee: AT&T Intellectual Property II, L.P.Inventors: Peter Frank Driessen, Mathias R. Kretschmer, Schuyler Reynier Quackenbush, James H. Snyder

Patent number: 7123919Abstract: In a cellular communication network, capacity in a cell is increased by placing antennas transmitting different signals on the same carrier frequency at separated signal transmission and virtual site locations in the cell, rather than at the center of the cell. A receiver includes multiple antennas using spatial diversity, such as beamforming and cancellation, to extract the desired signal.Type: GrantFiled: June 8, 2004Date of Patent: October 17, 2006Assignee: AT&T Corp.Inventor: Peter Frank Driessen

Patent number: 6968737Abstract: The present invention is a system and method for automated position location using RF signposting. The present invention comprises a plurality of transmitting units placed throughout a service area. Each transmitting unit repeatedly transmits a signal including position information related to a position associated with the transmitting unit. The position information may be an absolute position or an encoded position based on the structure of a building in which the transmitting unit is located. A receiving unit receives the signal transmitted from a transmitting unit and determines the position of the receiving unit, based on the received indication. The transmitting units are placed to provide uniform coverage of the service area, thus providing position location indoors and in urban areas where GPS does not function properly.Type: GrantFiled: January 2, 1997Date of Patent: November 29, 2005Assignee: Lucent Technologies Inc.Inventors: Kuo-Wei Herman Chen, Peter Frank Driessen, Richard Dennis Gitlin, Krishan Kumar Sabnani, Theodore Sizer, II

Patent number: 5890055Abstract: A wireless communications system includes a number of clusters of repeaters wherein all repeaters within a cluster arc connected to a common hub via respective millimeter-wave radio links. Wireless signals received by the repeaters from end-user devices are transparently carried by the millimeter-wave radio links to respective hubs that act as concentrators for the repeaters. The hubs may be linked to a wireless network base station (in an outdoor setting) or alternatively to a server or a PBX (in an indoor environment) via a high-speed transmission facility, such as a fiber optic cable that is thus shared by all the repeaters.Type: GrantFiled: July 28, 1995Date of Patent: March 30, 1999Assignee: Lucent Technologies Inc.Inventors: Ta-Shing Chu, Martin V.
