Have you ever wondered why your phone has three radios (LTE, Wi-Fi and Bluetooth), while your tablet and computer typically have two (Wi-Fi and Bluetooth)? For that matter, why do you know names like Wi-Fi, Bluetooth and LTE? What about 5G or Zigbee? At the same time that wireless data-communication technology and standards are still in development, new standards and proprietary technologies (like Zigbee) are clamoring for attention. How do we separate the noise from what is real and important? Should consumers care about any of this?
