  • Bluetooth 5:更快、更远、更强大,而且功耗依然很低!

    Song Bin 宋斌
    Song Bin 宋斌

    Bluetooth 技术联盟宣布推出令人期待已久的新版Bluetooth低能耗标准:新的Bluetooth 5 标准与其前代Bluetooth 4.2 相比,容量增加,速度更快(是前代的两倍),而且传输距离更远(四倍范围)。随着容量增加,可广播的内容将越来越多(800% 以上),从而能获得更重要、更完整的信息,实现更多 IoT 应用。

    这样蓝牙低能耗标准才算是实至名归。为了提高速度、拓展范围和增加容量,需要通过堆栈更改收发器。作为唯一一家可内部提供 RF 堆栈解决方案的公司,ARM 具备引领市场实施和实现这些功能的独特能力…
