WiFi到底怎么运作

一位穿青色衬衫、亲切的主持人指向一张发光的路由器3D示意图，路由器向漂浮的设备发出无线电波，信号弧线和数据包动感地穿梭。干净的科技蓝背景带网格线。顶部是加粗标题「WiFi怎么工作」，白字配青色描边，一支绿箭头追踪一道信号，配一个灯泡图标。电波上有简单标签。清晰、勾起好奇，强对比的科普讲解氛围。

A friendly host in a teal shirt gestures at a glowing 3D diagram of a router beaming radio waves to floating devices, animated signal arcs and data packets zipping around. Clean tech-blue background with grid lines. Bold text 'HOW WIFI WORKS' in white with a cyan outline across the top, a green arrow tracing a signal and a lightbulb icon. Simple labels on the waves. Clear, curious, high-contrast explainer energy.
