Spectrum Clearing and Geo-Locating Legacy Signals

To meet demand for additional bandwidth for cellular and broadcast operations, national regulators are reallocating spectrum previously used for other applications. Before a new network can be rolled out within these frequencies, it is critical for the new license owner to confirm that all legacy users have terminated their transmissions. P/N: 11410-01154

Backhaul Requirements for Anritsu Remote Spectrum Monitors Use for RF Signal Tracking Applications

There are various methods for geo-locating an RF signal of interest. Primary alternatives include Power of Arrival (POA), Time Difference of Arrival (TDOA), and Angle of Arrival (AOA). In most situations where modulated signal bandwidths are greater than 25 kHz, TDOA provides the best accuracy. This application note focuses on the use of TDOA as a means for tracking a signal.

Anritsu MS27103A Remote Spectrum Monitor — The perfect tool for satellite signal monitoring

The MS27103A is ideal for satellite operators and broadcasters who need to rely on clear communication channels to ensure optimal performance. A typical earth station will consist of many satellite dishes, all of which need to be monitored in real time. The MS27103A multiport remote spectrum monitor enables the spectrum of each satellite uplink or downlink to be monitored for spectral purity and the presence of interferers. Alarms can be automatically triggered on detection of unwanted interferers that would degrade the signal integrity.

Anritsu MS27103A Remote Spectrum Monitor — The perfect tool for cellular spectrum assurance

Interference mitigation of cellular networks is a top priority for optimizing networks and maximizing revenue for cellular network operators. The MS27103A provides spectrum assurance with all applications being accessed and controlled remotely. Interference and unusual signal activity can be monitored and recorded, threshold alarms can be set and signals of interest geo-located. With the Anritsu spectrum monitoring system, your spectrum investment is protected.

Anritsu MS27102A Remote Spectrum Monitor — The perfect tool for military and security spectrum monitoring

Reliable communications are critical for both military operations and for testing high-tech systems which rely on wireless command and control. Security at military facilities, national boarders, utilities, airports and other sensitive sites must all have access to communications free of impediments and distortion. Spectrum monitoring is crucial to insure that such facilities remain free of interference.

Anritsu MS27102A Remote Spectrum Monitor — The perfect tool for government regulators

The MS27102A is part of a spectrum monitoring system used to identify and measure spectrum usage and to locate and remove illegal or unlicensed interference signals. This is key in keeping critical communication channels such as transport, broadcasting, public safety and utilities free of impediments and distortion. Regulating the use of radio transmissions and mitigating interference in the spectrum has become a high priority with government regulators.

Time Difference of Arrival (TDOA)

Time Difference of Arrival (TDOA) is a technique for geo-locating RF sources. It requires three or more remote receivers (probes) capable of detecting the signal of interest. Each probe is synchronized in time to capture corresponding I/Q data blocks. Software shifts the time signature of each I/Q data set to find the difference in the arrival time at each probe. This gives the difference in the distance of the source from each set of probes. Using several probes provides a set of curved lines that indicate solutions to the distance equations. The actual RF source sits at the intersection of these lines.

TDOA can provide a very accurate location estimate (< 100 m) in a short period of time. To successfully use TDOA it is essential to understand the type of signals that can be used, how the results depend on the geometry of the measurement (probe and source locations), what the sources of uncertainty are and how to mitigate them, and how to know if the answer is meaningful.
