Have you ever seen a wifi signal, how far can a wifi signal travel will be the question answered in this articlehow far can wifi signals transmit.

How do wifi signals travel?
As we all know, wifi signals are invisible to the naked eye. In today's technological era, wifi is everywhere, so wifi signals are floating everywhere, especially in urban areas.
Wifi signals were discovered by two researchers Nickolay Lamm and Dr. M. Browning Vogel and defined as: Wi-Fi signals fill the air and travel in the form of encoded data pulses. The pulses indicate they are about 6 inches, about 15cm apart.
Wifi signals have many different connections. For different connections, there is always a specific coverage area. Normally, the wifi transmission range is 30m from the center point of the wifi transmission.
How far does wifi transmit?
One thing we must note is that the transmission signal is always transmitted best when the environment is free of obstacles.
Wifi was tested in a perfect environment with no obstructing objects, unaffected by electromagnetic waves and some other signal types, with a stable access line and using fiber optic internet, it can transmit signals within a range of 130 meters. In areas where the wifi signal is further from the device, the signal will be slower and the speed will also be much slower.
We can draw the following conclusions:
+ Wifi signals are affected by other signals operating in the environment, such as electromagnetic waves from electrical appliances (TVs, refrigerators, light bulbs...), telecommunication waves (3G, phone signals, walkie-talkies...) and many other types of waves.
+ Wifi signals are affected by signal-blocking objects such as partitions, walls, furniture in the home...
+ Wifi signals can also be affected to a very small extent by weather conditions.
Wifi signals transmit at different speeds depending on the transmission area

Measures to strengthen WiFi signal intensity
If you want to increase the WiFi transmission range, customers need to find a suitable place to place the WiFi. WiFi should be placed in a spacious area, without obstacles, and for multi-story houses, the WiFi router should be placed on the lowest floor.
Choose a location to get the best WiFi signal strength
You can point the WiFi antennas outwards on both sides to increase broadcasting capability. If your WiFi router does not have antennas, you can buy and install them.
Another way is to go into the WiFi settings, select the frequency to be 20 Hz/40 Hz and select channel 11. Since most WiFi routers originate from China, this setting will help the WiFi broadcast stronger and farther.
Another solution is to buy a WiFi extender (Range Extender). Currently, there are many range extenders from TP-Link; Xiaomi; Mercury; Tenda... which are very effective in extending the transmission range. You can place the WiFi on the 1st floor and still get full bars on the 3rd floor.
