Rumor: iPhones will have new "R1" coprocessor to locate "Apple Tags"

O MacRumors managed to get his hands on an internal build (used only inside Apple) of iOS 13. And, of course, this version of the system features news that is not present in the released versions for developers and participants of the Apple Beta Software Program.

The site has already discovered some things, such as information about such a Bluetooth tracker that Apple can launch, Apple Watch's possible new sleep monitoring feature, etc. Now they are back with more discoveries.

According to MR, iPhones to be introduced this week will have a new coprocessor. Codenamed Rose or β€œR1” (there are references to both names, but if Apple wants to do some marketing on that, the final name might be different), the M-series motion coprocessor-like component helps it tell iOS where the iPhone is located . What sets it apart, according to the site, is that it integrates far more sensors than the motion coprocessor to produce a much more accurate picture of where the device is.

Currently, the motion coprocessor integrates compass, gyroscope, accelerometer, barometer, and microphone data; β€œRose / R1” coprocessor, in turn, adds data support from an IMU sensor (inertial measurement unit, or inertial measuring unit), Bluetooth 5.1, UWB (ultrawideband, or ultra-band) and cameras (including motion capture and optical tracking).

With this, the coprocessor will not only be able to know where the device is, but also merge all this data to find such lost trackers (so-called "Apple Tags").

O MR argues that, given the overlapping information in the data collection and processing of this sensor data, it is quite likely that the new coprocessor would replace the "old" M-series coprocessor.

Note that the arrival angle (AoA) and departure angle (AoD) features of Bluetooth 5.1 allow directional tracking. If we combine this with the other data from the β€œR1” coprocessor, it is easy to predict that new iPhones will find Apple's trackers very precisely.

It remains to be seen whether these new trackers will only be compatible with new iPhones or if they will also work with older devices even less accurately, since even the XS, XS Max and XR iPhones do not even have Bluetooth 5.1.
