One challenging aspect of a Bluetooth-based approach is that the app must be open and in the foreground of the device (which must remain unlocked). That seems to be a common limitation with most other Bluetooth-based approaches (including Meridian), although it seems like the UK’s “NHS COVID-19” app has implemented a relatively untested workaround:

Maybe if you’ve got the full blown Meridian location tracking or something similar that can tie in Bluetooth-based beacons, but it seems to me that the granularity of Wi-Fi only data wouldn’t quite be up to what you’d need for effective contact tracing. I’m not completely convinced that Bluetooth doesn’t cast too wide a net either, but it’d be a lot better that Wi-Fi triangulation. Where we’re anticipating having the discussion around Wi-Fi data is gauging user/device density and duration of stay in general areas so that we can gauge what areas present the greater risks of exposure. There was a recent NYT article that explored this using cell phone location data. https://www.nytimes.com/interactive/2020/05/06/opinion/coronavirus-us-reopen.html<https://urldefense.proofpoint.com/v2/url?u=https-3A__www.nytimes.com_interactive_2020_05_06_opinion_coronavirus-2Dus-2Dreopen.html&d=DwMGaQ&c=WO-RGvefibhHBZq3fL85hQ&r=MOrPzn96ki798xbUwXJc6Hbb8ZwV-Df1GCkE26WPyzg&m=6Pv6VtEpHK3IKdxjA-5mKmZ5tx8onLW0n73s1lNzqSg&s=Ex7WTUkXv2YMcRkug0XOhFtmR9CXTH33iawJ7C0f6dw&e=> Going back to contact tracing, as of right now we see the value of trying to roll our own app or system to be limited given that there’s no way to tell what people are going to do when they leave campus. I’m hoping the state will come up with something workable that we can then point everyone here to use. -- Julian Y.

The question of “how far back do you keep wireless logs” was just asked which of course leads to “we want to see where a person has been on a given day”. This of course has privacy issues along with the technical challenges of storing and accessing that data. Has anyone else been asked to look into this or begun to make preparations for such? Being an Aruba shop we already leverage AirWave reports for our campus police when tracing lost or stolen devices as well as where a user has been or devices in an area at a specific time. This request seems to be a larger scale with potentially more moving parts. - Michael Michael McGuire Network Systems Administrator Monmouth University mmcgu...@monmouth.edu<mailto:mmcgu...@monmouth.edu> 732.263.5589 <image001.png><https://urldefense.com/v3/__https:/www.monmouth.edu/?utm_source=Email*Signature&utm_medium=email&utm_campaign=Email*Signature*Generator__;Kysr!!Dq0X2DkFhyF93HkjWTBQKhk!GxdXiJ7V22R-CDaaztQ6k-ODF5Ou3tlHTD5MIYpPr8iu4Avdrb9P8gdGGcZypbLaFMvufg$> 400 Cedar Avenue West Long Branch, NJ 07764 monmouth.edu<https://urldefense.com/v3/__https:/www.monmouth.edu/?utm_source=Email*Signature&utm_medium=email&utm_campaign=Email*Signature*Generator__;Kysr!!Dq0X2DkFhyF93HkjWTBQKhk!GxdXiJ7V22R-CDaaztQ6k-ODF5Ou3tlHTD5MIYpPr8iu4Avdrb9P8gdGGcZypbLaFMvufg$> <image002.png><https://urldefense.com/v3/__https:/twitter.com/monmouthu__;!!Dq0X2DkFhyF93HkjWTBQKhk!GxdXiJ7V22R-CDaaztQ6k-ODF5Ou3tlHTD5MIYpPr8iu4Avdrb9P8gdGGcZypbLnKTorsw$> <image003.png><https://urldefense.com/v3/__https:/www.facebook.com/MonmouthUniversity__;!!Dq0X2DkFhyF93HkjWTBQKhk!GxdXiJ7V22R-CDaaztQ6k-ODF5Ou3tlHTD5MIYpPr8iu4Avdrb9P8gdGGcZypbLszoFXbQ$> <image004.png><https://urldefense.com/v3/__https:/instagram.com/monmouthuniversity__;!!Dq0X2DkFhyF93HkjWTBQKhk!GxdXiJ7V22R-CDaaztQ6k-ODF5Ou3tlHTD5MIYpPr8iu4Avdrb9P8gdGGcZypbLwXUY6fw$> <image005.png><https://urldefense.com/v3/__https:/www.snapchat.com/add/monmouthu__;!!Dq0X2DkFhyF93HkjWTBQKhk!GxdXiJ7V22R-CDaaztQ6k-ODF5Ou3tlHTD5MIYpPr8iu4Avdrb9P8gdGGcZypbI6PXAvNQ$> <image006.png><https://urldefense.com/v3/__https:/www.linkedin.com/school/monmouth-university/__;!!Dq0X2DkFhyF93HkjWTBQKhk!GxdXiJ7V22R-CDaaztQ6k-ODF5Ou3tlHTD5MIYpPr8iu4Avdrb9P8gdGGcZypbI9xp1Rqg$> <image007.png> We are a green campus.
