Halo™
Mobile phone problems? Simply make them unusable with Halo™. The best way to control illegal mobile phone use in your facility is to make them all redundant.
Halo™ is designed to eliminate the unauthorised use of mobile telephones within facilities, such as prisons and other institutions where there is a NO MOBILE PHONES policy.
Halo™ can eliminate all mobile phone access but also has an optional managed access service that will only allow the use of pre-authorised mobile phones that have been registered within the system and apply full denial to all other mobile phones within the facility.
The system control, monitoring, set up, logs and database can be either a local or remote PC. The Halo™ system provides a passive means of checking the correct operation of the denial system to confirm and verify that no unauthorised access is applied. It will not matter how many illicit mobile phones enter your establishment as they simply will not be able to connect to a network.
Beyond the Jammer: A Sustainable RF Detection Strategy for Contraband Cellphone Control
Over the past decade, cellphone signal technology has undergone a rapid transformation—from the relatively simple and easily manipulated systems of 2G, to the secure, adaptive architectures of 4G and 5G. Modern mobile networks are designed for resilience, efficiency, and security, incorporating advanced protocols and dynamic frequency-hopping techniques that make them exceptionally difficult to intercept, spoof, or jam.
This shift presents a serious challenge for traditional signal-control solutions—particularly those deployed by the Department of Corrections. Many facilities that once invested heavily in IMSI-catcher technology to intercept and control inmate cellphone use have since paused or abandoned those efforts. The core issue lies in the ever-evolving nature of mobile communication: every new frequency band or protocol requires costly re-engineering and re-calibration, leading to ongoing maintenance burdens and diminishing returns. These systems quickly become outdated, unsustainable, and vulnerable.
Rather than engaging in an unwinnable technological arms race, we propose a smarter, more sustainable approach. Our RF detection systems offer correctional facilities real-time, site-specific visibility into cellular and other RF activity. This empowers decision-makers to:
- Understand the problem: Pinpoint where and how often unauthorized devices are being used.
- Measure interventions: Track how quickly illicit devices reappear after a search or enforcement action.
- Evaluate current tools: Assess the real-world effectiveness of existing jamming or IMSI-based technologies.
- Ensure safety and compliance: Monitor for signal spillover near public areas and validate full site coverage.
Whether you are currently using jamming, IMSI capture, dogs, or manual searches – our scalable RF detection solution enhances your existing anti-contraband strategy and ability to quickly eliminate cellphones, by delivering actionable intelligence and measurable outcomes.
