How Data Jam Measures
Location-specific audience measurement grounded in observed movement signals rather than generic area averages.
Location-specific audience measurement grounded in observed movement signals rather than generic area averages.
Observed movement data is converted into audience metrics through Data Jam's measurement methodology. Here is how that works, end to end.
JamBox sensors detect anonymised movement signals from mobile devices around each location. No cameras, no images, no sound — only signal presence and movement.
Signals are anonymised at the point of collection. Data Jam does not identify individuals, track people across locations, or hold personal data about the audiences it measures.
Observed movement data is processed into audience metrics — volume, dwell and movement — for each measurement zone, at hourly and daily granularity.
Metrics are delivered in real time through the Data Jam Portal, Campaigns and PULSE, and to your own systems via the API.
Measure proximity, movement and dwell across zones tailored to each location and format.
A roadside billboard, a shopping centre atrium and a transit platform are different environments — so each deployment is configured with measurement zones that reflect how audiences actually encounter that location. Zone-level reporting separates immediate, near and wider audiences, so the metrics describe genuine exposure to the media, not just general activity in the area.
Full technical specifications for JamBox, including maximum detection range, are on the JamBox product page.
Credible measurement means being precise about what the data represents.
Data Jam metrics describe observed audience presence, dwell and movement at a location — the opportunity to see your media, measured where the media actually is.
No signal-based system can confirm that an individual looked at an advert. We report exposure and movement, not verified viewing — and we're clear about that distinction.
Measurement is based on anonymised signals. Data Jam does not identify individuals, build profiles, or follow people between locations.
Metrics are grounded in what is observed at each site, rather than survey panels or broad area models — so two sites on the same street can, correctly, tell two different stories.
Privacy-first isn't a feature of the system — it's the design principle the system was built on.
Measurement uses anonymised signals with no cameras and no personal data collection, supporting GDPR-aligned deployment across the UK and Europe.
The same privacy-by-design approach supports deployment in the US, including CCPA considerations for California networks.
A Data Protection Impact Assessment (DPIA) is available on request to support your own compliance and procurement processes. Request the DPIA.
Clients receive audience counts, dwell and movement patterns — never individual-level records. See our Privacy Policy for full details.
Data Jam metrics are grounded in observed movement signals collected at each location. The measurement methodology converts that observed data into audience metrics — so the starting point is always what actually happened at the site, not a survey panel or an area-level model.
JamBox measures anonymised device signals as a consistent, continuous indicator of audience presence. Like any measurement approach, it is a representation of audience activity — its strength is that it is location-specific, continuous and consistent over time, which makes trends, comparisons and campaign windows genuinely comparable.
Audience volume, dwell and movement by measurement zone, with hourly and daily granularity, historical trends, and comparison views across locations — delivered through the Portal, Campaigns, PULSE and the API.
Data is timestamped, location-specific and available at fine granularity, so clients can interrogate it against known events — footfall peaks, event days, closures — and validate it against their own sources. Talk to us about validation for your network.
