High precision radio wave technology opens new doors for Apple

There's more going on in Apple's product line than meets the eye.

From MacRumors' "Apple Said to Be Driving Market Growth of Ultra Wideband Applications," posted Wednesday:

Ultra Wideband is a short-range, low-power radio technology that is able to provide more precise indoor positioning than Bluetooth LE and Wi-Fi. The distance between two UWB devices can be measured precisely by calculating the time that it takes for a radio wave to pass between them.

Apple's iPhones have included it in the last two series via its custom U1 chip, with other Apple products also supporting UWB. According to today's [Digitimes] report, Apple's promotion of Ultra Wideband has been the driving factor behind increased take-up of the technology...

Apple's HomePod 14.4 beta is set to introduce new ‌HomePod mini‌ music handoff functionality that takes advantage of the U1 chip in the device: When an ‌iPhone‌ is near a ‌‌HomePod mini‌‌, it begins a soft haptic touch rhythm that gets faster and faster as the ‌‌iPhone‌‌ gets closer, until the interface to transfer a song between the ‌‌HomePod mini‌‌ and the ‌‌iPhone‌‌ opens...

Apple's rumored "AirTags" will also feature ultra wideband tech, according to analyst Ming-Chi Kuo, while Tile is said to be planning to introduce an upgraded series of item trackers that include a UWB chip for more precise tracking.

Just last week, BMW announced future plans to roll out Digital Key Plus, an enhanced version of Apple's Car Keys feature that incorporates Ultra Wideband technology, enabling drivers to unlock and start their vehicle without needing to take their ‌iPhone‌ out of their pocket or bag.

My take: Find my keys and find my remote will be the killer apps.

    If they can somehow embed a tracker inside my AirPods case, then “WTF did I put my airpods *this* time” would be the killer app of killer apps for me…
