Unverified传输方式选专用RF射频（433MHz/868MHz）而非蓝牙，RF在同层住宅穿1-2堵墙可达50-80米，蓝牙实测穿墙后常降至10米内且易断连81% similarUnverified追求穿墙覆盖与追求峰值速率存在矛盾：160MHz超大频宽虽提升单点速率，但频段越高（5GHz/6GHz）穿墙衰减越严重，多墙老房应优先看2.4G/5G低频段增益而非纸面峰值带宽77% similarUnverified选路由器优先看空间量级而非纯覆盖面积：≤90㎡两室一厅单台AX3000够用；120㎡以上或有承重墙/多层户型应上Mesh或AX6000三频，单台大功率路由靠信号强度硬穿墙效果远不如多点组网76% similarUnverified承重墙多的老房子应优先选支持穿墙的低频段优化机型或多点Mesh，160MHz大带宽虽快但穿墙衰减严重，隔两堵墙后速率反而不如80MHz稳定76% similarUnverified2.4GHz穿墙能力强于5GHz，穿2堵承重墙后5GHz信号衰减严重，穿墙场景应确认路由器支持频段智能切换或2.4G功率增强，而非盲目追求高频高速73% similar
