Bluetooth-4.0

iPhone 4S just launched yesterday and introduced a number of impressive features, but one feature that is ignored at the time of the announcement yesterday was the support for Bluetooth 4.0. The latest version of the standard wireless technology to exchange data over short distances may not cause big problems today, but it would be a problem in the future. So, what makes Bluetooth 4.0 to be very special?

Bluetooth-4.0

One of the key features of Bluetooth 4.0 is the low-energy technology. With Bluetooth 4.0, accessory or device that needs to be constantly sending data back and forth will benefit from it. Users do not need frequent recharge their devices, and leave it in the long term will not affect phone battery life dramatically. Examples of such devices is largely a health and fitness category: pedometers, measuring heart rate and blood glucose monitors.

Devices such as wireless headsets for listening to music or hands-free communication will also benefit from low-power technology. But, as we know, most current devices do not even take advantage of Bluetooth 3.0. This makes us have to wait before actually seeing the Bluetooth 4.0 is widely adopted, and when the time comes, the iPhone 4S will be ready to work with these devices.
