US Patent:

8135339, Mar 13, 2012

Filed:

Dec 31, 2008

Appl. No.:

12/347098

Inventors:

Chris Ranson - Concord VA, US
Van Hanson - Forest VA, US
Thomas Kummetz - Forest VA, US

Assignee:

Andrew LLC - Hickory NC

International Classification:

H04B 7/14

US Classification:

455 24

Abstract:

An apparatus for repeating signals includes a receive antenna for receiving input signals, processing circuitry for processing the input signals to form repeated signals, and a transmit antenna for transmitting the repeated signals. The processing circuitry includes an adaptive digital filter configured to generate cancellation signals that are added to the input signals to cancel unwanted feedback signals from the input signals. A frequency shifting circuit adds a frequency shift to the input signals, after the addition of the cancellation signals, to form repeated signals that are frequency shifted from the input signals. A digital signal processor is coupled to the adaptive digital filter for digitally adapting the filter. The digital signal processor utilizes the frequency shift of the transmission signals to adapt the adaptive digital filter.

Abstract:

A distributed antenna system is provided for communicating with a plurality of base stations. The distributed antenna system includes a system controller and a master unit communicating with at least one of the plurality of base stations. A remote unit communicates over a high data rate media with the master unit and/or a downstream remote unit. Alternatively, the distributed antenna system includes a controller and a digital time/space crosspoint switch controlled by the controller. A digitizing transceiver is in communication with the digital time/space crosspoint switch. The crosspoint switch is configured to transmit and receive digital data through the digitizing transceiver.

US Classification:

455 111, 455 16, 455 7, 455 9

Abstract:

A signal repeating system for a wireless network includes an antenna configured for transceiving signals between a base station and a user equipment device. Repeating circuitry is coupled to the antenna and defines an uplink path for signals from the user equipment device to the base station and a downlink path for signals from the base station to the user equipment device. The repeating circuitry includes gain circuitry and gain control circuitry that is coupled to the gain circuitry. The gain control circuitry is operable for varying the gain of the repeating circuitry according to a waveform. Measurement circuitry measures the receive power in the uplink path over time from the user equipment device. Processing circuitry cross-correlates the inverted gain variation waveform with the measured receive power for determining the existence of traffic from user equipment devices in the uplink path.

International Classification:

G08B 23/00

US Classification:

340517

Abstract:

The sensor network may include a location capture processing unit; and a plurality of sensors in communication with the location capture processing unit. Each sensor of the plurality of sensors includes a controller and a RF receiver configured to receive RF signals. The RF receiver is in communication with the controller. A localization engine is configured to receive beacon signals transmitted by other sensors in the sensor network. The localization engine is in communication with the controller. The controller of each of the plurality of sensors is further configured to determine a position of its respective sensor using either RF receiver or localization engine or both. The plurality of sensors communicates their position to the location capture processing unit.

International Classification:

H04B 3/36

Abstract:

Repeaters, event those having digital processing, exist. The significant drawback of these digital repeaters is that the computational complexity or the processing speed has to be very high in order to guarantee, particularly when compensating for echo, that the necessary delay does not excessively impair the performance. The aim of the invention is to provide a structure of the repeater in which the computational complexity is reduced without this reduction having a negative effect on the performance during signal filtering and/or suppression of natural oscillation. To this end, the invention provides that in order to carry out bandpass filtering, adaptive pre-equalization and suppression of the natural oscillation, the components of the repeater in the uplink branch and downlink branch are arranged in a designated sequence, whereby duplex filters are used for coupling both repeater branches to the antennas. In addition, only one reconfiguration in the modules at the user is necessary in order to adapt to user-specific requirements. The invention is used in the field of digital repeaters for data systems technology and telecommunications technology.

US Classification:

Abstract:

A method of monitoring an element in wireless communication system is provided. An operational noise measurement is obtained by measuring a noise value outside of a bandwidth of a first device, but within a bandwidth of a second, subsequent device. The operational noise measurement is alternatively obtained by tuning an input band of the element to shift the input band partially or completely outside of a bandwidth of a first device to create an open band or by suppressing an input of the antenna and measuring noise within the open bandwidth of the element of the wireless communication network. A stored parameter is retrieved and compared to the measured operational noise. Alternatively, a leakage signal of the element may be received at a signal receiver and compared to a reference. The reference is a function of components of the wireless communication system in a leakage path of the leakage signal.
