Assignee:

International Classification:

H04Q 522

US Classification:

340 104, 340 101, 340 103, 340 1031, 340 1032, 34082569, 34082572, 3405721, 340 591, 340 592, 342 51, 455 412

Abstract:

A modulated backscatter communication system (e. g. , an Electronic Shelf Label (ESL) system) includes a central node (e. g. , a ceiling node) and one or more remote nodes (e. g. , ESL tags). The central node transmits a downlink radio signal which is reflectively modulated at a remote node to produce a modulated reflected radio signal. At the remote node, a precise-frequency subcarrier signal is modulated with an uplink information signal to produce a modulated signal which is used to produce the modulated reflected radio signal. At the central node, the modulated reflected radio signal is received, detected and narrowband filtered to obtain the modulated subcarrier signal which is then demodulated to obtain the uplink information signal, with great immunity to close to carrier downlink radio noise and fluorescent light backscatter interference.

International Classification:

H04B 7/19

US Classification:

455 132, 455 121, 455427, 370316

Abstract:

User equipment of a communication system in one aspect obtains data indicative of the position of a satellite, and obtains data indicative of the position of the user equipment. The user equipment computes a delay measure based on the data indicative of the position of the satellite and the data indicative of the position of the user equipment, and adjusts the timing of a communication transmitted from the user equipment to the satellite based on the delay measure. In an illustrative embodiment, the user equipment receives data indicative of position and velocity of the satellite, and adjusts both timing and frequency of the communication based on the position and velocity data. The timing and frequency adjusted communication may then be transmitted to the satellite over a unicast uplink channel.

Lily Zhu - Parsippany NJ, US

International Classification:

H04Q 7/20
H04M 1/00

US Classification:

455445000, 455427000

Abstract:

In one embodiment of the method, a base station is configured to divide a coverage area of the base station into sub-coverage areas. Each sub-coverage area has a smaller range of round trip propagation delays than a range of round trip propagation delays for the coverage area of the base station. Each sub-coverage area may have a different range of round trip propagation delays.

International Classification:

H04B 7/15

US Classification:

455011100, 455522000, 455069000

Abstract:

A method and an apparatus for enabling a digital wireless service across a first and a second wireless communications environment is provided. The method comprises translating a receive signal carried on a forward link and having a first carrier frequency in the first wireless communications environment from a first frequency band to a second frequency band different from the first frequency band. The method further comprises translating a transmit signal carried on a reverse link and having a second carrier frequency in the first wireless communications environment from the second frequency band to the first frequency band. In this way, a digital wireless service may be provided between a mobile station and at least one base station on the ground across two different wireless communications environments. The method further comprises compensating Doppler shift separately for individual beams directed at a plurality of terrestrial base stations. The method further comprises injecting an additional path delay to insure that the terrestrial base stations receive reverse link signals at substantially similar round trip time offsets and to reduce search windows for the terrestrial base stations. In this way, a wireless communication system may enable in-flight use of a mobile station to communicate with one or more base stations on the ground.

Stephen A. Wilkus - Monmouth NJ, US

International Classification:

H04L 27/36

US Classification:

375298

Abstract:

A method for modulating first and second bit streams in a communications network that supports at least one of a binary phase-shift keying (BPSK), a quadrature phase-shift keying (QPSK) or a quadrature amplitude modulation (QAM) constellation uses hierarchical modulation. A hierarchical modulation parameter that varies within the network is set. The first bit stream is modulated based on a first constellation of the hierarchical modulation and the hierarchical modulation parameter. The second bit stream is modulated based on a second constellation in the first constellation.

Assignee:

AT&T Global Information Solutions Company - Dayton OH

International Classification:

H04B 1700

US Classification:

455 677

Abstract:

Electronic display system capable of displaying communication signal strength on individual electronic display modules and method of using the same. In one preferred embodiment of the present invention, a pseudo-price change command is transmitted by a base communication station to an individual electronic display module and the strength of the acknowledgment signal returned by the individual electronic display module is observed and temporarily recorded. The base communication station then transmits a command to change the electronic display on that particular electronic display module to display the value of the received communication signal strength.
