UWB is the acronym for ultra-broadband, a short-range communications technology that is not new, but is resurfacing these days with the support of Apple, Samsung, Sony or Xiaomi. After the UWB landed on Android in the hands of the Samsung Galaxy Note 20, Google is already working on official UWB support on Android.
For now, the only Android phones launched with UWB support are the Samsung Galaxy Note 20, for which Samsung has had to create its own implementation in its software. To unify the use and make it easier for developers to use this type of connectivity under a single implementation, Google has added a UWB API to Android.
UWB connectivity on Android
We’ve been hearing for years that ultra-broadband connectivity was the future, and while the technology has been somewhat eclipsed by Bluetooth and NFC, UWB presents in a good number of improvements over Bluetooth– Higher transfer speed, higher location accuracy, low interference generation and a theoretical advantage over Bluetooth for transferring materials.
Considering the above, it is understandable that the big names in technology have been investing in UWB for some time and promoting its use through associations such as the UWB Alliance. This year, in addition, is when UWB connectivity on mobile has started to come true, as it is included in both the iPhone 11 and higher and the Galaxy Note 20.
Now, the AOSP code Android reveals that Google is working on the official UWP API, thus formalizing its use and, what is more important, unifying its use before we have a different implementation by each manufacturer.
This API is still a bit green, so unclear if it will be ready for Android 12, although it is a first step. UWB technology itself is also starting to take off now, and Samsung only uses it, at the moment, to search for devices with SmartThings Find.
