The Bluetooth Special Interest Group has released specifications for the next generation of the low-power, short-range wireless communication protocol.
Bluetooth 4.2 will support faster data speeds, offer improved power efficiency, and enhanced security. It will also allow Bluetooth-capable devices to connect to the internet through a router or other access point — no WiFi required.
The Bluetooth SIG says the new Bluetooth protocol has a packet capacity that’s up to 10 times greater than earlier versions and supports data transfer speeds that are up to 2.5 times faster.
The new support for internet connectivity will also come in handy with the growing number of Internet-of-Things devices such as smart light bulbs, thermostats, and other home and/or wearable devices since it’ll allow them to communicate with online apps without requiring a WiFi connection.
We should start to see Bluetooth 4.2 enabled devices in 2015.
