When you start your microwave, do you lose the Wi-Fi signal on a nearby device? Wi Fi and microwaves operate at a similar frequency, which can lead to interference.
1947 the International Telecommunication Union (ITM from International Telecommunication Union) created ISM, Industrial, Scientific and Medical (ISM bands from Industrial, Scientific, and Medical).
The aim was to define the devices that would be allowed to use specific radio frequency bands so as not to interfere with other radiocommunications services.
ITM has defined the 2,4 GHz band as a spectrum for microwave ovens. This band does not require much energy for the transmission, and it can at relatively lower power heat up the food. These of course have reduced the cost to the consumer.
As the name ISM suggests, it was originally intended to be used only in devices that do not provide communication. Since then, however, wireless devices have been released phones, radiotelephones and more recently Wi-Fi. The 2,4GHz band was ideal, with low cost, lower power requirements and decent range capabilities.
Everything that runs in the ISM bands is supposed to be designed to avoid interference, and Wi-Fi devices use algorithms for this purpose. However, a microwave oven is strong enough and can affect nearby WiFi signals.
Microwave ovens have "shielding" to prevent leaks, but no matter how we do it is not F. So it is not uncommon to have one leakage in a microwave oven.
Microwaves and Wi-Fi devices use a similar frequency that can interfere with each other. Your WiFi will of course not show anything remarkable in the microwave because of its "shielding."
WiFi and microwaves use a similar radio frequency, but they exist two major differences: focus and power.
A Wi-Fi router sends the signal everywhere. It sends it in every direction in an imaginary circle.
The microwave, on the other hand, sends its signal in only one direction, approximately to the center of the oven. This signal continues until it hits the sides or the bottom of the oven, bounces and returns with a slightly different angle.
It's not a perfect system due to the nature of the radio waves, so every microwave has hot and cold spots. This is why the ovens have rotating dishes.
Microwaves also use more power than a Wi-Fi router. They usually produce 1000 watts of power. Conversely, a typical Wi-Fi router produces about 100 milwave (or 0,1 watts).
If you notice problems interference, you don't need to replace your microwave oven. In all likelihood the leak is minimal and not harmful to you or those around you.
Wi Fi is much more sensitive and does not need much to accept interference. Instead of replacing the microwave you could just move it.
Alternatively, use another Wi-Fi frequency (5ghz). Not only will you avoid interference from the microwave, but you will also prevent interference from your neighbors.
