Last week Apple launched a new MacBook Air series in which it implemented Bluetooth 4.0 technology, the newest version available for electronic products. Bluetooth 4.0 is the version that has the lowest energy consumption paired with the lowest latency for data transfer. Apple is among the first companies in the world to implement this technology and the MacBook Airs are only the first products to have it incorporated. The new iPhone that will be launched in just a month will almost certainly have it and the iPod Touch and the iPad 3 tablet will not be forgotten by Apple.
Although Bluetooth technology cannot be used to transfer any files from our devices to other devices from other manufacturers, there are still a multitude of accessories that can. uses. From simple hands-free to sensors implemented in sports shoes or phones that give us notifications about SMS or phone calls received on our terminal. Bluetooth technology would even allow locating our devices if the distance between the device and the device we are looking for is less than 5 meters, but the possibility of locating does not end here.
One key application could be indoor location (where there is no GPS signal) whereby sensors around a large public building (such as an airport or rail station) constantly broadcast information about their location. A Bluetooth low energy equipped cell phone passing within range could then display that information to its owner. Sensors could transmit other information such as flight times and gates, location of amenities, or special offers from nearby shops.
Those from EETimes I argue that the new technology can be used to locate users inside buildings or in areas where the GPS signal is weak. Of course, Bluetooth technology can be used for the device to communicate with a wide range of products in a similar way to NFC technology, but it all depends on the implementation.
