材料 | 对信号的影响(衰减程度) | 说明 |
🪵 木头、胶合板 | 低衰减 | 信号可轻松穿透,影响较小 |
🧱 砖墙、水泥墙 | 中等衰减 | 吸收较多信号,特别是厚墙体 |
🧊 玻璃 | 中等至高衰减 | 普通玻璃影响较小,但镀膜玻璃、双层玻璃信号衰减大 |
🪟 金属(门、电梯、橱柜) | 极高衰减 | 几乎完全阻隔Wi-Fi信号 |
🚪 实木门 | 中等衰减 | 比墙略低,但仍能造成可见信号下降 |
🚿 水(如浴缸、鱼缸) | 极高衰减 | 水对Wi-Fi信号吸收非常严重 |

WikipediaIEEE 802.11IEEE 802.11
IEEE 802.11 is part of the IEEE 802 set of local area network (LAN) technical standards, and specifies the set of medium access control (MAC) and physical layer (PHY) protocols for implementing wireless local area network (WLAN) computer communication. The standard and amendments provide the basis for wireless network products using the Wi-Fi brand and are the world's most widely used wireless computer networking standards. IEEE 802.11 is used in most home and office networks to allow laptops, printers, smartphones, and other devices to communicate with each other and access the Internet without connecting wires. IEEE 802.11 is also a basis for vehicle-based communication networks with IEEE 802.11p.
