Which Building Materials Can Block Wi-Fi Signals?

Why is reception of Wi-Fi bad in part of your home or in areas outside your home? This may be due to the material used on the wall or other physical barrier that blocks or weakens the Wi-Fi signal.

Concrete is one of the worst building materials of radio signals with or without metal reinforcement, but masonry blocks and bricks are also serious obstacles to Wi-Fi.

Figures and figures in the table below are based on the results of numerous experiments conducted by the National Institute of Standards and Technology.

Do you know that there are multiple versions of Wireless Internet Wi-Fi? The most common Wi-Fi standard is called 802.11 and was published by the Institute of Electrical and Electronics Engineers (IEEE) in 1997. At that time, Wi-Fi only supported connections up to 2 Mbps. With each iteration of 802.11b, 802.11a, 802.11g, 802.11n, and recently 802.11ac (also known as Gigabit Wi-Fi), the speed has improved significantly. Since then, Wi-Fi has made great strides, the latest standard (802.11ac) supports speeds up to 1300 Mbps (actual speed is usually close to 200 Mbps). In addition to the speed, the maximum number of connected devices increases with increasing 802.11ac and can support up to four devices at the same time. For four or more devices, the router quickly switches data transfer between devices to handle all attached devices. Therefore, it is very important to check the router and check the type of Wi-Fi it broadcasts. This will affect the speed of the Internet.

Your internet may not be a problem, but your Wi - Fi is connected to the internet - there is a signal problem. Especially affect all equipment in the home, bad Wi-Fi connection seems to be a problem of Internet connection. There are several reasons why you may have bad Wi - Fi signals. In particular, using 2.4 GHz instead of 5 GHz can support more devices. This is a particularly common problem in dense urban areas. For example, if you live in an apartment building, your neighbors have many devices such as wireless routers.
