Google and Apple both have WiFi geolocation databases. As far as I can tell there's no way for an AP to opt-out of Apple's database.
Interesting tidbit from [1]: "In older versions of Apple's mobile OS (1.1.3 to 3.1), Apple relied on Google and Skyhook Wireless to provide location-based services -- so Apple left data collection to them. But ever since April 2010, starting with iPhone OS 3.2 and continuing into the current iOS 4 software, Apple has started using its own databases to provide location-based services to iOS devices."
I remembered that Apple has such a database too, and interestingly, here's a project that reverse-engineered queries to Apple's Wi-Fi geolocation service: https://github.com/zadewg/GS-LOC
When office shutdowns started happening, everyone waited for the big tech companies to make the call and copied them, just like how everyone followed Google's leetcode and hire model for all SWEs in SV.
I believe Google made the 3 days in office call starting Sept first and places started following suit.
FWIW, Google afterwards opened up the possibility of full-remote work (saying they expect ~20% of the workforce to do that iirc), but individual PAs will need to come up with actual guidelines which are due in a couple of weeks.
> While 20 percent of its 140,000 employees will be fully remote
Also, further down
> While Google says the majority of its employees will work from the office around three days a week, it also says it’ll make it easier for employees to switch between offices or to work fully remotely.
Meanwhile, the subtitle of OPs is:
> Employees can work remotely for up to two weeks a year
And there's nothing about full time remote. So they seem quite different.
To add dang (and for others), for future reference: in regulatory affairs, “cleared”, “approved”, “granted”, and “authorized” are distinct actions for the FDA. These verbs are not interchangeable and using the wrong word can bring significant (financial, for the associated company) consequences because it implies that the FDA did something they did not, e.g., cleared for a 510(k) device vs granted for a de novo device.
Particularly someone asked whether Uber could scale the approach. I couldn't find how many cities in which Uber uses corrected GPS, except a 2018 Verge article that says "15, launching soon globally". Either way, seems like the answer is Google has the data to do it. And Google can bring it to every (non-China) Android phone.
But yeah, Google's post is very light on technical details. It'd be interesting to see if their approaches were similar.
Edit: also of note, Uber used server-side correction (at least in 2018), while Google downloads 3D tiles to the device.
Correct me if I'm wrong, my read is that this is a competitor to Google's external BeyondCorp solution[0]? (They reference the BeyondCorp papers in the post.)
ZeroTrust (BeyondCorp) is one component of SASE. For a while marketing departments were throwing ZeroTrust on everything, but eventually a new buzzword arose to better differentiate that component from the bundle of the whole kitchen sink. https://www.sdxcentral.com/security/sase/definitions/what-is...
