Bluetooth-Tec – Bluetooth/BLE Detection & Tracker Awareness for Critical Environments

Make Bluetooth visible. Detect rogue devices. Enforce “no-wireless” zones with Edge AI.

bluetooth-tec is the Gigahertz Security product line for passive Bluetooth and Bluetooth Low Energy (BLE) detection in sensitive environments. The system detects Bluetooth/BLE activity (including beacon-like behavior), supports classification of suspicious patterns and anomalies, and triggers configurable alerts and workflows—for critical infrastructure operators (KRITIS), government sites, industry/R&D, logistics and high-security facilities.

Bluetooth-Tec builds on the proven HFA7 platform, enhanced with high-speed RF processing and Edge AI pattern recognition focused on Bluetooth/BLE behavior—designed to turn the wireless “airspace” into actionable operational signals.

Why Bluetooth/BLE Detection Has Become Essential

Bluetooth/BLE is everywhere: wearables, headsets, access devices, asset tags and IoT. In security-critical environments, that ubiquity creates a new risk surface:

  • Trackers and covert beacons (unauthorized tracking, asset manipulation, insider threat scenarios)
  • Rogue devices / shadow wireless (unapproved beacons, devices brought into restricted areas)
  • Wireless policy violations (“no Bluetooth” zones, secure meeting rooms, sensitive labs)
  • Covert proximity activity (short-range signals that are easy to miss but operationally relevant)
  • Multi-vector scenarios (Bluetooth combined with Wi-Fi/cellular/IoT behaviors)

Policies alone often do not scale because Bluetooth devices are small, silent and can operate intermittently. Bluetooth-Tec adds a technical enforcement layer: detect, classify and document Bluetooth/BLE activity where it should not exist—or where it behaves unusually.

Technology Approach: Passive Bluetooth/BLE Detection (No Transmitting)

bluetooth-tec operates purely passively. It does not transmit signals and is designed for detection, classification and operational alerting. The system focuses on making Bluetooth/BLE activity visible and actionable—without relying on manual searches or ad-hoc smartphone checks. In many environments, Bluetooth/BLE monitoring is part of a broader wireless threat detection mindset: treat “airspace events” as security-relevant telemetry, similar to logs in IT security.

What bluetooth-tec detects

  • BLE advertising / beacon-like activity
  • Bluetooth activity patterns consistent with devices operating in proximity
  • Rogue Bluetooth/BLE devices (unapproved presence in restricted zones)
  • Anomalies (unusual activity density, recurring patterns, sudden “new device” behavior)

Bluetooth-Tec is designed to support security workflows such as “new/unknown wireless activity in a secure room” or “tracker-like beacon behavior near controlled assets”—based on detection patterns and context.

bluetooth-tec provides a set of operational capabilities that turn Bluetooth and BLE activity into clear, actionable security signals. It enables early detection in “no-wireless” zones by identifying Bluetooth/BLE activity as soon as it appears—creating an effective early warning layer in environments where devices can be small, hidden, or transmit only intermittently. To support real-world response workflows, Bluetooth-Tec offers zone-oriented guidance that helps teams narrow down where suspicious activity is occurring using practical area and zone logic, so incidents can be handled quickly and efficiently in real facilities—not just under lab conditions.

Beyond simple “signal present” alerts, Bluetooth-Tec delivers practical risk and proximity indication by evaluating activity intensity and behavioral trends, allowing security teams to prioritize incidents based on operational relevance—for example persistent beacon-like behavior or recurring events in sensitive areas. At the core of the platform is Edge AI classification, which focuses on patterns rather than raw signal level alone. By analyzing behavioral context, Bluetooth-Tec can distinguish Bluetooth/BLE-typical activity from background RF and common interferers, reducing false alerts and improving decision-making under time pressure. When relevant events occur, the system supports real-time alerting and logging with acoustic, visual, or tactile alerts depending on the device or installation. Events can be forwarded to control rooms/SOC, security software and incident workflows, and operational dashboards or reporting systems where required, while detailed event logs provide the documentation needed for audits, investigations, and escalation processes.

bluetooth-tec is available in both mobile and stationary configurations. The handheld version is a portable tool for rapid checks and situational awareness, ideal for security teams and patrols, spot checks in suspected tracker or rogue device scenarios, and temporary operations such as events, high-security meetings, or ad-hoc investigations. It provides a fast overview of current Bluetooth/BLE activity in the environment and supports immediate on-site action. The stationary version is designed for permanent 24/7 monitoring in defined zones, including secure meeting rooms and restricted government areas, R&D labs and controlled industrial spaces, KRITIS sites with enforced “no-wireless” policies, and logistics areas or sensitive assets depending on the deployment. Multiple sensors can be networked to scale monitoring across larger sites and enrich operational context for more reliable, consistent security operations.

Open Interfaces and System Integration

bluetooth-tec is designed as an integrated sensor layer, not an isolated product.

 Interfaces (planned / optional, project dependent)

  • REST API
  • MQTT
  • TCP/IP
  • Cloud connectivity
  • On-prem processing and integration

Typical integrations

  • Control rooms / alarm servers
  • Security software and incident workflows
  • SIEM/SOC dashboards (where applicable)
  • Policy enforcement workflows and reporting

bluetooth-tec delivers wireless activity intelligence—your systems define the response.
