Bluetooth 4.0 specs out, ready to hit markets by year end

The Bluetooth SIG has started to push the next version i.e. Bluetooth 4.0 already. While we are still seeing numbered devices offering Bluetooth 3.0 being announced, Bluetooth 4. 0 is said to be ready for a year end launch. The high power requirements for Bluetooth 3.0 has been a deterrent to its adoption and thats exactly what the new version fixes. The new 4.0 specs supports even coin-cell batteries to compared to the minimum requirement of a AAA or larger capacity battery for Bluetooth 3.0.

Bluetooth 3.0 has enabled data transfer speeds of upto 24 Mbps by allowing Bluetooth transfers to piggyback on WiFi – 802.11 signals. The Bluetooth 4.0 specification retains this speed (25 Mbps) and brings in lower power requirements. This promises that Bluetooth 4.0 would see much faster and widespread adoption compared to v3.0.
