Take for instance, a scenario that involves shopping, with Bluetooth beacons been installed. Version 4.2 would ensure that those beacons are unable to track your movements unless you have given those beacons prior permission to hook up to your device.
Apart from that, Bluetooth SIG also claimed that data transfers have been improved through the boosting of the packet capacity of data. In other words, users would be able to enjoy more reliable and faster data. How much faster, you ask? We are looking at as much as 2.5 times compared to the previous Bluetooth versions. As a result, these are supposed to deliver fewer data transmission errors in addition to a reduction in battery consumption. Are you stoked with what Bluetooth 4.2 will be able to offer?
