Lost in all the hoopla surrounding the new iPad Retina display is the fact that the third generation iOS tablet comes with Bluetooth 4. Although this feature has been somewhat overlooked, the addition of the latest and greatest Bluetooth technology to the iPad is significant. Apple's iPhone 4S, launched in October, was the first smartphone to support the new standard.
Now that the iPad 3 has Bluetooth 4 what does this mean? The latest Bluetooth is dubbed Smart Ready, which means that wireless devices in the pipeline are going to be capable of connecting with the iPad using much less power. Bluetooth Smart will broadcast data in low-power radio mode, making the technology perfect for things like security sensors, key fobs, watches and heart rate monitors.
