Very cool. But does this work if the device is actually trying to use its wifi connection for data? I'd assume that rapidly hopping between all the channels would interfere with the normal duties of the wifi card.
- pmontra 11y agoI think that if a device hops in the 2.4 GHz band it loses the connection to the AP and it goes offline. So this location system will be useful to locate carts in a shop but not customer's phones connected to that shop free WiFi. And even if the customer is not connected to the AP and the phone still has the WiFi on (extremely common), I think you need an app to do that. Furthermore I expect this to impact on battery quite a bit.
