 The ability of wireless communication to penetrate walls depends mainly on which indicators The penetration ability of wireless communication is mainly determined by the following factors: 1.Frequency of the wireless signal 2.Transmit power of the wireless signal 3.Type and gain of the antenna 4.Material and thickness of the wall 5.Indoor environment layout 6.Wireless communication protocols and technologies 1. Frequency of the wireless signal The frequency of the wireless signal is an important factor affecting the penetration ability. Generally, wireless signals with lower frequencies (such as Wi-Fi, LoRa frequencies at 433/868/915MHz) have a longer wavelength and better penetration ability, able to penetrate through walls and obstacles more effectively. In contrast, wireless signals with higher frequencies (such as Zigbee frequencies at 2.4GHz) have a shorter wavelength and weaker penetration ability, resulting in faster signal decay and reduced penetration ability when encount...

  The reliability of wireless communication transmission is crucial to ensure that information is transmitted accurately, completely, and stably during the sending and receiving process. Here are some ways to ensure the reliability of wireless communication transmission:   1. Selecting Suitable Frequency Bands and Modulation Methods The selection of frequency bands and modulation methods in wireless communication has a significant impact on transmission reliability. Different frequency bands have different signal propagation characteristics, and selecting the right frequency band can help reduce transmission interference and attenuation. Additionally, choosing the right modulation method, such as QAM (Quadrature Amplitude Modulation) or OFDM (Orthogonal Frequency Division Multiplexing), can increase the signal's error-correcting capability and improve transmission reliability.   2. Optimizing Antenna Layout The antenna layout is a critical component in wireless communicat...
