Upcoming Bluetooth 4.1 cuts reliance on smartphone for cloud access


Bluetooth 4.1 is due to be out by the end of this year, and will be upgradeable over-the-air for devices already equipped with Bluetooth 4.0. What is notable is how the update will make it possible for devices to upload data directly to the Internet. In addition, Bluetooth 4.1 is also designed for incorporation into home routers or special hubs to receive Bluetooth data and redirect it to the Internet.

As such, wearable devices will no longer have to rely on a smartphone app to communicate with cloud services, as long as they are within range of a home router or set-top box that supports Bluetooth 4.1. This would essentially allow device makers to bring wireless Internet access at a significantly lower power consumption compared to Wi-Fi.

As reported on Computerworld, chief marketing officer Suke Jawanda of the Bluetooth Special Interest Group talked of how this can benefit the wider market beyond just consumer gadgets. For example, health monitors could dispatch data directly to a cloud service, triggering an alert to either healthcare professionals or relatives if the readings are a concern.

Bluetooth 4.1 is the first major update since 2010 when Bluetooth 4.0 was announced, and is designed with minimum changes to the hardware. We noted that shipments of Bluetooth-enabled devices is projected to hit 4.5 billion over the next five years when we last reported on this topic late last year, and the release of Bluetooth 4.1 should see most existing Bluetooth 4.0-based hardware, if not all, being upgraded to it.
