AirTag is certainly not an uncharted territory. We have seen a lot of similar tracking devices Tile and Samsung. Apple is the biggest asset to Apple’s ecosystem, and in particular – the Find My app and network, which is by far the largest on the planet.
One of these considerations is that AirTags don’t seem to work as well when they’re “lost” in a multi-story building, as they do when they’re in the wrong place in larger spaces. Ben Sin, who lives in a multi – storey building in Hong Kong with access to several floors. If he happens to place an object incorrectly on one floor and then move to another layer, AirTag will not send the exact location for the precision search feature to work, which means it will have difficulty calculating the vertical distance (height).
Still, regular AirTag tracking can tell you that tracking is basically in the same building, but it’s not very useful if you work or live in a skyscraper.
This problem will not affect everyone. Hong Kong is, of course, a fairly specific case study. Apartments or even two-story houses with a spacious staircase should not cause the same problems, which means that North American users are unlikely to be affected.
In fact, people who live in a tall building often only have access to one floor where their apartment is, so AirTag should work just fine. However, if you work in a tall building where you are constantly moving between floors, the AirTag may not be the most useful device for your needs, like someone else.
There is an interesting statistic on the subject that comes from SkyScraperCenter in countries with the tallest city buildings around the world. It’s no big surprise that China is at the top of the list with 2395 (150m +), 823 (200m +) and 95 (300m +) buildings. The “highest city” is Hong Kong, which perfectly explains Ben’s view.
The United States is second with 825 (150m +), 220 (200m +) and 28 (300m +) tall buildings. Ironically, The Big Apple is Apple’s Achilles heel. New York is the “tallest city” in the United States. The UAE is third on the list, then we have the island of Japan and South Korea is fifth.
We think the pickup is: lower your floor if you want to trust the AirTag.
