The new iteration of Bluetooth has just been announced and it looks to help improve internet connectivity for Bluetooth-dependent devices.
The introduction of Bluetooth 4.2 will prove to be a boon for Internet of Things devices, wearables and home automation as it allows these devices to connect directly to the internet. This means that there is no longer a requirement for these Bluetooth-dependent devices to go through a specialized hub for their internet connection, be it your smartphone or PC. Bluetooth 4.2 utilizes low-power IPv6/6LoWPAN protocols to connect to internet routers and hot-spots, plus all the data will be dedicated to the Bluetooth device unlike in situations using a hub.
Bluetooth 4.2 also has some upgrades over its predecessor. For one, privacy has taken center stage, where the tracking of your device without permission by other devices is now much harder. Improved performance is also expected with sources claiming data speeds up to 250 percent and a 10 fold packet capacity increase. We also expect improved energy efficiency.
There will be some waiting involved before we can fully see the full range of Bluetooth 4.2’s capabilities. Even though the Bluetooth 4.2 standard is ready for use, most manufacturers have not made use of it as of yet. As such, it would be well into 2015 before we are able to fully utilize a Bluetooth 4.2-compliant device.
