Normally the 2.4GHz radiation penetration is better than 5.8GHz, the effects of the barrier are as follows. Here use 2.4GHz as an example. Cement Wall (15~25cm): attenuation 10~12dB (Effective coverage ≦ 5meters) Wooden Wall (5~10cm): attenuation 5~6dB (Effective coverage ≦ 15meters) Glass (3~5cm): attenuation 5~7dB(Effective coverage ≦ 15meters)
