Abstract: At least two input signals, each characterizing a radio signal having a radio frequency (RF), are received. The input signals are converted into at least three output signals. The output signals have a unique combination of corresponding magnitudes for each RF phase difference between the input signals. A set of magnitudes corresponding to the output signals is measured using a mobile measuring device. An RF phase angle value is determined based the measured set of magnitudes. The RF phase angle value is converted into an angle value indicative of the direction of arrival of the radio signal.

Abstract: There is provided techniques for improved visualization of wireless devices in a communication network. The techniques include receiving, via an identification device, real-time display data, determining, via the identification device, a location of a network device and displaying, via a display of the identification device, the real-time display data and an indication of the location of the network device relative to the real-time display data.

Abstract: A device provides location information to assist in identifying the location of RF sources. Antenna arrays coupled to corresponding receivers supply signals to a direction of arrival computation block, and the direction information is used to provide a display showing the location of the RF source.

Abstract: A method, apparatus and software related product are presented for adaptive frequency-domain windowing to determine a time-domain crosstalk in a cable and produce effective TDX plots regardless of the frequency of a worst NEXT (near-end crosstalk). An adaptive window such as a low pass or pass band window may be selected based on the frequency of a measured worst NEXT margin for each pair combination.

Abstract: A method of correcting distortions resulting from loss and dispersion in cable fault measurements. A cable is measured in the frequency domain to obtain a reflected response. Fractional sinusoidal components of the reflected response having attenuated amplitude and delayed phase values at points defining the junctures of adjacent equal predetermined lengths are collected and normalized. Then the fractional sinusoidal components of the reflected response are extracted from normalized sum by mathematically calculating the real value at each point, thereby removing all loss and dispersion distortion components.

Abstract: A balance network directional coupler (BNDC) allows for effective coupling to sources of transmitted signals, communication lines, and devices that process received signals. The BNDC includes a transmission port, first and second amplifiers, a reception port, a communication line port, a transformer system, and a balance network. The second amplifier has a second gain of a polarity opposite the polarity of the polarity of the first gain. The transformer system has first and second windings each having first and second terminals, the first and second terminals of the first winding being electrically coupled to the communication line port, the first terminal of the second winding being electrically coupled to the reception port, and the second terminal of the second winding being electrically coupled to an output terminal of the second amplifier.
