越来越多的日常数字设备，包括智能手机、门锁，甚至最新的汽车，现在都使用一种称为空间感知的无线功能。具有空间感知功能的数字设备可以了解它相对于其他设备的位置，然后对这些设备的位置变化做出响应。空间感知功能使我们——这些数字设备的用户们，可以更轻松地度过每一天。
Today, we have an assortment of wireless protocols so that it might become a little confusing to check them all. On one hand, it is helping developers of wireless technology to address specific issues in design. On the other hand, it also makes identifying the right protocol a bit different task. It becomes particularly true when we have to choose between BLE (Bluetooth low-energy) and Bluetooth Classic. A person who is not a tech expert may assume BLE and Bluetooth as the same devices. However, it is crucial to know the differences, advantages, and disadvantages of all options to choose a perfect Classic or BLE gateway.
