Rohde & Schwarz will deliver 26 more spectrum monitoring vehicles to the Office of National Broadcasting and Telecommunications Commission of Thailand for interference hunting applications, the assignment of new frequencies and other tasks for optimizing spectrum use.
Thailand’s Office of National Broadcasting and Telecommunications Commission is expanding its R&S ARGUS spectrum monitoring system from Rohde & Schwarz with 26 additional interference hunting vehicles. The technical parameters for the vehicles/mobile stations and measurement equipment comply with ITU recommendations and guidelines, enabling both manual measurements and radio frequency direction-finding.
Since 2014, Rohde & Schwarz has supplied the NBTC with seven spectrum monitoring vehicles that use the R&S ARGUS monitoring system, allowing them to keep pace with advances in communications technology and the ever-growing number of radio services. The authority can use the system to verify compliance within licensed parameters and guidelines for transmitter systems. Any violation or radio interference source can be detected, identified and tracked to the transmitter source.
Anne Stephan, Vice President Critical Infrastructure at Rohde & Schwarz said that these mobile systems provide more benefits to NBTC by expanding remote RF interference detection, localization and identification capabilities for all kinds of modern communications signals. A database and a geographic information system (GIS) provides additional support. The new 26 mobile stations can be combined to form a single sensor network or operated individually.
The monitoring stations cover a wide frequency range. An R&S DDF550 wideband direction finder is at the core of each station, providing both direction finding and signal monitoring. The R&S DDF550 receives signals from the compact R&S ADD253 correlative interferometer direction finder antenna mounted on the roof, making this compact mobile platform very practical.
