Why RF detection is becoming a security baseline

Whether it’s a drone near the perimeter, an unauthorized phone inside a restricted zone, or hidden Bluetooth trackers — wireless activity is often the earliest technical indicator of a security incident. Traditional layers (camera, radar, policies) can be too late or may not deliver usable situational context. Gigahertz Security adds a robust, weather- and visibility-independent layer to your security architecture: Airspace Awareness.

WHAT YOU GET:

DETECT
RF activity inside defined zones

CLASSIFY
patterns and risk indicators instead of “just signal level”

TRIGGER
alerts and integrations into your operations

Three product lines — one platform approach

drone-tec

drone-tec – Drone Detection & Airspace Monitoring
Passive detection of drone-related RF emissions with directional and proximity indicators and real-time alerting — as a trigger for cameras, control rooms or counter-UAS systems.

fon-tec

fon-tec – Mobile Phone & Cellular Activity Detection (2G–5G)

Visibility into Bluetooth/BLE activity in no-wireless zones and suspected tracker scenarios — for operational checks and continuous monitoring.

Limitations of Traditional Security Systems

Why Visual Surveillance Alone Can’t Stop RF-Based Threats

Conventional security tools — such as CCTV cameras, motion detectors and basic radio scanners — were never designed to detect modern RF-based attacks. Cameras struggle in darkness, fog and bad weather, and they cannot see small or camouflaged drones. Fences and motion sensors only react once an intrusion is already in progress.

At the same time, today’s attackers rely on sophisticated wireless technologies. They use 4G/5G mobile networks, Wi-Fi 6, Bluetooth Low Energy, GPS trackers and custom radio links to coordinate operations, control drones or trigger attacks remotely. Static spectrum analyzers and manual scanning cannot keep pace with frequency-hopping, encrypted or low-power emissions.

As wireless threats evolve, your security posture must evolve as well. Without dedicated RF detection, critical operations remain blind to the most dynamic part of the threat landscape: the radio spectrum.

The Gigahertz Solution

AI-Based RF Detection and Classification in Real Time

Gigahertz Security delivers an AI-based RF detection platform engineered specifically for critical infrastructure and high-security environments. The system continuously monitors a wide frequency range — from 400 MHz to 12 GHz, optionally expandable up to 28 GHz — and uses artificial intelligence to analyse, classify and prioritise RF activity in real time.

Instead of simply flagging “unusual” signals, the platform understands what is transmitting and how it behaves. It automatically distinguishes between mobile devices (GSM, UMTS, LTE, 5G), Wi-Fi access points, Bluetooth devices, GPS trackers, UWB beacons, walkie-talkies, UAV controllers and other wireless sources. This enables early identification of concrete threat vectors such as:

contraband cell phones hidden inside prisons,
RF jammers near military or government facilities,
reconnaissance drones over solar farms, industrial plants or vehicle compounds.

The system integrates via APIs into existing security infrastructure — including video management systems, PSIM platforms and access control solutions. It can be deployed indoors or outdoors and continuously adapts to new signal patterns, protocols and attack techniques without the need for manual reconfiguration.

Edge AI Technology – Insights where they’re needed

Gigahertz Security focuses on edge-based signal processing: classification and pattern recognition run close to the sensor — enabling low latency, better operational robustness and controlled data flows. That turns raw RF into actionable security events: What is it? How relevant is it? What should happen next?

Real-time over post-analysis: faster alerting and response
Patterns over raw levels: fewer false positives through context
Scalable architecture: from handheld units to networked sensor setups

From RF to actionable situational data — in a few steps

Detect: capture RF activity in relevant bands and defined zones
Classify: analyze patterns (drone-typical, cellular-typical, BLE/beacon-like)
Assess: apply risk indicators and prioritization via profiles
Integrate: deliver alerts/logs via interfaces into your control room or tools

Why AI-Based RF Detection Is Superior

From Raw RF Data to Actionable Security Intelligence

Traditional RF monitoring solutions depend on manual tuning and a fixed set of known frequencies. They can show you that “something” is happening in the spectrum — but not who is transmitting, what protocol is being used, or why the activity is suspicious. This makes it hard for security teams to prioritise alarms or take targeted action.

Gigahertz Security takes a different approach. Our AI-driven pattern recognition engine automatically:

detects deviations from baseline RF activity,
identifies the likely signal type and source category,
correlates events across time and location,
and highlights RF behaviour that matches known threat scenarios.

Instead of flooding operators with raw waterfall displays and general warnings, the system delivers clear, actionable insights — for example “possible drone controller detected near north perimeter” or “cluster of active contraband phones in cell block C”. This turns RF monitoring from a niche specialist task into a practical tool for everyday security operations.

Applications Across Critical Sectors

Proven RF Detection in High-Risk Environments

From corrections and defence to energy, industry and logistics, RF threats are increasing in scale and sophistication. Gigahertz Security helps operators monitor wireless activity around their sites, detect anomalies and respond before disruption, theft or data loss occurs.

RF Detection for Prisons and Correctional Facilities

In correctional environments, contraband mobile phones and drones pose a direct threat to safety and order. Illicit devices are used to coordinate crime, intimidate witnesses and manage operations outside the facility. Drones can deliver weapons, narcotics and tools directly into prison yards. Our RF detection system provides continuous monitoring of the RF spectrum inside and around the prison. It identifies active and idle mobile devices, Wi-Fi and Bluetooth connections, as well as drone controllers and telemetry links approaching the site. Security teams receive early warning of suspicious RF activity and can locate hotspots, enforce device policies and coordinate rapid response.

Protecting Solar Farms and Renewable Energy Sites

Remote solar farms and wind parks are attractive targets for organised theft, sabotage and vandalism. Criminals use drones for reconnaissance and wireless tools to coordinate attacks under cover of darkness. Gigahertz Security continuously monitors RF activity around panels, inverters and substations. The system flags unusual nighttime transmissions, radio traffic near critical assets and repeated drone flyovers. This allows operators to intervene before equipment is damaged, energy production is interrupted or safety incidents occur.

Tactical RF Monitoring for Military and Government Sites

Military bases and government facilities face highly advanced RF threats — from GPS trackers and covert mobile phones to frequency-hopping surveillance drones and RF jammers. These tools can be used for reconnaissance, data exfiltration or disruption of critical operations. The Gigahertz Security platform is built for demanding tactical environments. It detects and classifies even low-probability-of-intercept signals, encrypted transmissions and burst communication patterns. Commanders gain a detailed picture of the RF situation in and around the facility, enabling proactive countermeasures and rapid investigation of suspicious events.

RF Security for Industrial Sites and Construction Projects

Large industrial complexes and construction zones are frequent targets for equipment theft, sabotage and espionage. Unauthorised radios, rogue Wi-Fi access points and untrusted LTE hotspots can be used to coordinate theft, bypass safety procedures or extract sensitive data. With Gigahertz Security, operators can detect and investigate these wireless threats early. The system automatically spots unknown access points, unusual push-to-talk traffic and RF clusters near high-value equipment — helping prevent downtime, delays and financial losses.

Securing Logistics Hubs and Vehicle Compounds

High-value vehicles and goods in transit are often surveilled and targeted using RF trackers, covert radios and drone flyovers. Without dedicated RF detection, many of these activities remain invisible until after a theft or loss has occurred. Gigahertz Security detects GSM and 5G-based tracking devices, encrypted radio networks and drone-based mapping operations around logistics hubs, ports and vehicle compounds. RF alerts give security teams early warning of coordinated theft attempts and help protect supply chains in high-risk export zones.
