Identify mobile devices and protect examination integrity
Mobile phones, smartwatches, earbuds and other connected devices present an increasing challenge for examination providers.
Comms-Tek provides wireless detection solutions that help organisations screen for unauthorised devices, monitor wireless activity during assessments and investigate detections when concerns arise.
Whether you’re operating a professional testing centre, apprenticeship assessment centre, university assessment facility or commercial examination service, our solutions help protect assessment content, maintain confidence in assessment outcomes and strengthen examination security.
The challenge
Many examination providers require candidates to surrender phones and other connected devices before entering the assessment environment.
While these procedures can be effective, they rely heavily on candidate compliance. Hidden mobile phones, smartwatches, earbuds and other connected devices can be difficult to identify using visual checks alone.
Many organisations also use metal detector wands as part of their security procedures. While useful for locating metal objects, modern mobile phones can be surprisingly difficult to detect reliably. Much of a smartphone is constructed from materials that are not easily detected using conventional metal detection methods.
To improve phone detection rates, operators often have to increase sensitivity significantly. This can result in detections from keys, belt buckles, jewellery, footwear and surrounding metal structures such as doors, furniture and reinforced concrete floors, making screening slower and more difficult to manage.
Examination providers need practical ways to verify compliance, investigate concerns and respond quickly when unauthorised devices are suspected.
For commercial assessment providers, maintaining robust examination security is about more than compliance. It helps protect examination content, maintain client confidence, retain existing contracts and demonstrate a commitment to secure assessment delivery.

How Comms-Tek can help
Dedicated detectors for exams and testing centres
A structured approach to device detection helps teams move from identifying suspicious activity through to locating and recovering concealed devices.
Our devices can support you:
Screen candidates
Screen candidates for smartphones, smart devices and Bluetooth devices before they enter the assessment environment.
Monitor assessments
Monitor examination halls and testing environments for cellular, Wi Fi and Bluetooth activity throughout an assessment.
Investigate detections
Carry out targeted follow-up checks to identify and locate the source of detected wireless activity.
Protect assessment content
Reduce opportunities for unauthorised communication, access to online information and the removal of examination material from the assessment environment.
Detect phones in standby mode and even switched-off devices*
Many detection technologies rely on a phone being actively used in order to generate a detection.
Ranger™ helps identify smartphones that are not actively being used, including phones in standby mode and switched-off smartphones with offline location features enabled.
This provides examination providers with an additional layer of security when screening candidates and investigating suspected device use.
*Detection of switched-off smartphones depends on device type, operating system, configuration and the availability of offline location features.
Protecting assessment content
Assessment providers invest significant resources in assessment development, delivery and invigilation.
Mobile phones and connected devices can provide access to unauthorised information, facilitate communication outside the examination room and create opportunities for assessment content to be copied, photographed or removed from the assessment environment.
Strong examination security procedures help protect assessment materials, maintain client confidence and demonstrate a commitment to secure assessment delivery.
For commercial examination providers, robust examination security can also help retain existing contracts, strengthen bids for new business and differentiate services in an increasingly competitive market.
