Bluetooth 4.2 Is Meant For Internet Of Things

Bluetooth 4.2 specs are out and they're clearly hinting at a world where everything around you is connected to the Internet. But 'Internet' isn't the first thing that comes to mind when we talk about Bluetooth. Most of us will think about transferring photos and small files over short distances; and that's exactly what the Bluetooth SIG (special interest group) wants to change. They're making Bluetooth 4.2 so that it can make the Internet Of Things work. Let's take a quick peek at Bluetooth 4.2 features.

It's estimated that in the next few years, by 2020 about 28 billion devices will be connected to the Internet including your car, your toaster, guitar, shaver et al. With Bluetooth 4.2 technology, these 'things' will be able to connect to the Internet using Bluetooth via a router or an access point without needing any intermediate device. You may imagine that this is a huge step for the IoT!

Bluetooth-42-Specs

The engineering team that worked on BT 4.2 specs also put the privacy and security as their top priority. It addresses the gaps in the previous specifications and make it almost impossible to track any device via Bluetooth, without your explicit permission. Bluetooth 4.2 is also about 2.5x faster and 10x bigger in capacity. The power consumption is also extremely low so that keeping Bluetooth on won't drain your gadget's battery.

You will have to wait 2015 Q2 or Q3 for Bluetooth 4.2 to make it to the gadgets. Be assured that your patience will pay off.

    IOT is not exactly Internet. It's similar to MANET with a little longer range
