  1. Risk of cancer.

There is a chip in smartphones that emits radiation from various wireless devices. The Scientist believes that this radiation under long periods of time will help develop tumors, but under the fact of there being no hard evidence this problem has been dismissed. To back up this argument scientists have reported that the tumors would take up to ten years to build up. So of course, there haven’t been any case yet.

  1. Insomnia

It has been discovered that sleeping in places with Wi-Fi signals can result in not being able to sleep. The Wi-Fi pollution changes sleeping and falling asleep patterns, therefore, creating insomnia which can lead on to many other big problems like depression and hypertension.

It has been said that young children and pregnant women should avoid exposure of Wi-Fi as it affects human development, as scientists have realized this. They have said that they never meant to address the exposure of Wi-Fi that now affect approximately 4 billion people.

To prove how this happens a simple experiment was taken, a plant was grown in a room with as much electromagnetic radiation as cell phones have and another was grown in a room with no electromagnetic signals, it turns out that the plant in the room with the radiation didn’t even grow while the other one did, just imagine the effect this has on children.

This will increase the cost.

  1. Speed

Nowadays the speed that a wireless network provides is typically 1 – 54 Mbps, which is slower than wired networks.


The conclusion is that the Wi-Fi network is not perfect. There are many advantages and disadvantages of Wi-Fi. However, it has a lot of advantages.  Hence, every day, this modern technology is becoming popular and its uses are increasing on large scale.
