Because:
- using a cellular modem requires a high capacity battery
- if you hide a tracker well, it probably won't have a good GPS reception
Apple's BLE-based network solves both of these problems.
- LeoPanthera 5y ago> using a cellular modem requires a high capacity battery The example third party AirTag clone described on the linked page is powered by a full size USB power bank.
- kayson 5y agoBecause it's a proof of concept using an ESP32, not because that battery capacity is fundamentally necessary for the idea to work. It could easily be optimized for power and size. Sure, it will have to use more power than a vanilla airtag, because it's doing (slightly) more, but not enough to make a significant difference.
- Friday_ 5y agoThose are not problems that needed to be solved. Problem is: 1. Precise location of tracked object, now This is actually one problem and Apple didn't solve it very well, airtag doesn't work in real-time. You only get updates when there are people near object that uses iphone.
- quenix 5y ago> You only get updates when there are people near object that uses iphone. Ok? In practice, this is most of the time. In most reasonable use cases (i.e. excluding the Sahara desert or some remote mountain).
- rahimnathwani 5y ago> Those are not problems that needed to be solved. An AirTag might help me find my keys if they fall out of my pocket in a restaurant restroom. A cellular-based tracker won't because (1) it will be out of battery, and (2) it won't have a GPS signal.
- Friday_ 5y agoI guess its a good key finder, maybe best key finder there is. But we are seeing people explore other posibilities. Can it track vehicles, people, or pets? Some people say that this key finder is revolution. I dont think so.
