How Wi-Fi Works

A technology infographic explaining how Wi-Fi delivers internet, shown as a layered flow from the internet cloud to a phone. Stages - a fiber line, a modem, a router broadcasting radio waves, and connecting devices - each carry an icon, with concentric signal-wave rings radiating from the router. Clean modern flat style, a cool blue-and-teal palette with a magenta signal accent on light grey. Numbered captions, bold title 'How Wi-Fi Works' upper-left, a small frequency badge (2.4 vs 5 GHz) and a range diagram in the corner.

一张技术信息图,讲解 Wi-Fi 如何传送网络,呈现为从互联网云到手机的分层流程。各阶段——光纤线路、调制解调器、广播无线电波的路由器,以及连接的设备——各配图标,信号波环从路由器同心扩散。干净的现代扁平风格,冷调蓝青配色,品红信号点缀,浅灰底。编号说明,左上角粗体标题「Wi-Fi 是怎么工作的」,角落一个频段标签(2.4 与 5 GHz)与一个覆盖范围示意图。
