Main Library Floor Occupancy Indicator

A display screen in the forum of the Main Library provides an indicator of occupancy of each Floor of the Main Library. This is based upon wifi connections, using anonymized and aggregated data derived from wifi access point logs and is updated every five minutes. This is a pilot service running until 27 March.

We are providing a graphical visualisation on a single display screen in the forum of the Main Library as an indicator of how busy each Floor of the Main Library is at any given time, which may be helpful when looking for study spaces when visiting the Main Library.  The display screen is in the vicinity of the lifts and adjacent to the café entrance within the forum.

Updated every 5 minutes, you can see an indicator of occupancy based upon connections to the wifi access points in the Main Library

This is a pilot service running until 27 March. We shall be conducting a student led feedback evaluation during the pilot period – if you are interested in joining in with the evaluation review, or if you wish to ask a question about the pilot service, please email

The wifi data is derived from existing information sources – wifi access point logs - and has been anonymised and aggregated. Encryption methods and de-identification processes are used to ensure privacy is protected. Any identifiable data held within the system is rendered unidentifiable through the application of a secure crypto-hash and randomly assigned replacement de-identifier mechanism, prior to analysis both for real-time monitoring and scheduled reporting.

We have carried out a detailed privacy impact assessment, which has included reviews by our Data Protection Officer, as well as the Governance & Ethics Action Group on the Internet of Things Programme. We have also carried out a security assessment of the solution.
