碩士 === 醒吾科技大學 === 資訊科技應用系 === 105 === Bluetooth Low Energy (BLE) is a new technology, although he has some of the same technology as the previous generation of Bluetooth (BT), but he introduced the elements of low energy, and traditional BT compared to his needs, and design We will use the BLE that the new Bluetooth Low Energy, BT on behalf of the traditional (Bluetooth) BLE, target by the speed into low power, which is compared with other wireless protocol evolution is very different, to give up speed, but To low power, you can call a few days or even several months a few years goal, in addition to low power another goal is low cost, low cost have the opportunity to move towards high volume, have the opportunity to BLE can then a lot of various things ( IoT), low cost key lies in the following three items: SM Band, we all know that 2.4GHz ISM band without license, so this is one of the reasons BLE low cost. BLE's design goal is to use button-cell batteries, which means that his goal is not high-speed transmission, is not suitable for applications such as file transfer, video streaming, and traditional BT lock target customers , This is the BLE characteristics. If able to provide accurate indoor location services used in the shelter management also represents a more open application services.
