Solutions — Government and Public Safety
From spectrum awareness to multi-domain situational awareness — safeguarding national security
Drawing on more than 90 years of innovation, Rohde & Schwarz gives government agencies, law enforcement and critical infrastructure operators end-to-end security solutions that span detection, analysis and response, covering spectrum monitoring, counter-UAS, cellular network analysis and millimeterwave security screening.
Core pain points for government and public safety organizations
The digital threat environment is moving fast, and government agencies and critical infrastructure operators face a wider range of security challenges than ever before. From blind spots in the electromagnetic spectrum to low-cost drones, these are the core pain points public safety organizations in Taiwan report most often:
- Blind spots in the electromagnetic spectrum leave gaps in border and perimeter awareness, so illicit activity is hard to see in real time
- The spread of low-cost commercial off-the-shelf (COTS) drones creates a persistent intrusion threat that conventional defenses were never designed to handle
- Large volumes of data from heterogeneous systems are difficult to consolidate, leaving investigators to extract usable intelligence with limited resources and under heavy time pressure
- Encrypted communications make cellular network analysis more complex and slow criminal investigations down
- Manual security screening is slow and intrusive, and cannot deliver the throughput that high-traffic sites such as airports and border crossings need
Solutions across the whole public safety domain
From border surveillance and drone defense to cellular network analysis and millimeterwave screening, R&S solutions can be deployed across the land, sea, air and electromagnetic domains.
Border and Perimeter Surveillance
Built around electromagnetic spectrum awareness, integrating five sensor classes — CNA, SATCOM, ELINT, COMINT and C-UAS — through a sensor and data fusion software platform that turns fragmented electromagnetic signals into a single situational picture shared across agencies, so border police, intelligence services, armed forces and the coast guard can work from the same view. The core workflow: detect (unauthorized or hidden signals in the spectrum) → analyze (correlation, classification and context) → respond (coordination, lawful countermeasures).

Counter-UAS
The THORIS multi-sensor architecture (radar + EO/IR + RF under a single C2 layer) supports continuous detection, tracking and identification, and covers wideband jamming together with the integration of non-kinetic and precision hard-kill effectors, including laser. ARDRONIS is a purely passive RF detection system: it emits nothing, and captures and analyzes the drone remote control link for early detection, classification, direction finding and localization. STANAG-aligned and SAPIENT-compatible.

Spectrum Monitoring
A complete portfolio of portable, mobile and fixed-station spectrum monitoring systems built in line with ITU recommendations, serving regulatory authorities, network operators and military users for nationwide band compliance audits, interference hunting and detection of unauthorized signals. Flagship products: R&S®ESMW (ultra-wideband) and R&S®HE800-DC30 (handheld, to 33 GHz).
R&S official page
Cellular Network Analysis (Government and Intelligence)
R&S®NESTOR (with the TSMx scanner series) provides automatic channel detection (ACD), airborne and ground-based cell position estimation (APE/CPE), cell measurement and evaluation (CME), base station analysis and monitoring (BSA/BSM), rogue base station detection (COD) and search-and-rescue support (SAR/ICP). Post-processing can be done in the field or remotely, for intelligence investigations, critical infrastructure protection and F2/F3 missions.
R&S official page
Lawful Intelligence and Intelligence-Led Policing
An ontology-based platform for semantic linking and visual analysis that brings heterogeneous sources together — cellular network data, open-source intelligence (OSINT), spectrum monitoring, counter-drone systems — and adds explainable AI reasoning with an end-to-end audit trail. GDPR- and NIS2-compliant and lawful by design, with sovereign deployment options (cloud or edge), for criminal investigation and public safety decision-making.
R&S official page
mmWave Security Screening
R&S®QPS201 (static, high resolution) and R&S®QPS Walk2000 (walk-through, 360° whole-body, highest throughput) identify metallic and non-metallic threats, liquids and ceramics automatically using AI, and work with non-ionizing radiation that is safe for the person being screened. Approved by the European Civil Aviation Conference (ECAC) and the US TSA, and deployed at major airports and correctional facilities worldwide.
R&S official page
Signal Intelligence (SIGINT) and Electronic Warfare
Covers ELINT radar interception and analysis, wide-area COMINT communications intelligence (ground-based and airborne reconnaissance) and SATCOM satellite communications awareness, supporting strategic signal intelligence collection and integrating into a multi-domain situational awareness framework for border protection.
R&S official page
Secure Networks and Cybersecurity (Public Sector)
