Currently, Wifi routers are designed to operate on two different frequencies, either 2,4 GHz, or 5GHz, or both 2,4 and 5 GHz. You can see this information in the router box or in the characteristic.
What is the frequency itself?
In short, the waves propagating through the air propagate at different levels so that they do not interfere with each other, do not extinguish each other, this level is called frequency, that is, in physical language, a certain the number of oscillations over time.
To give a rougher but clearer example, planes fly at different altitudes so that they don’t hit each other, which is also the case.
The 2,4 GHz frequency is the most popular, because in addition to the WiFi router, microwaves, radio telephones and other modern devices also operate at this frequency, which means that the demand for this frequency is high.
Advantages of 2,4 GHz:
? All devices can receive this frequency.
? There are too many ports.
? High power signal.
? Can easily overcome various obstacles.
Disadvantages:
? The demand for the range is high, so there are interruptions, resulting in interruptions.
Devices that use the 5 GHz frequency are rare, so stable internet can be accessed through this frequency, but there should be a place away from the signal barrier wall, door, etc., because this frequency is very sensitive to interference.
5 GHz frequency advantages:
? Loading in the range is low and a stable signal can be achieved.
? The number of frequency channels is large.
? Transmission speed is high.
Disadvantages:
? You are resistant to obstacles.
? Not all devices can accept this frequency.
? The radius of propagation is small.
So who is comfortable working at what frequency?
In multi-storey houses, the demand for 2,4 GHz is very high, every apartment has WiFi hotspots, electric kettles, radio telephones, and this makes the signal unstable. Therefore, it is good that these users get a router with both 2,4 and 5 GHz frequencies, initially tested at 2,4, if there is no stability, they switch to 5 GHz. Do not remove the 5 GHz router immediately, as you may remember that there are obstacles in your apartment.
In backyards, the 2,4 GHz frequency is probably not a problem, for them this choice is better.
☝️Many people buy a router without paying attention to this characteristic and then quarrel with the internet provider, why is the internet not stable? Then if you connect to the internet via cable, you will see that everything is in place. So to check the stability, first check the internet connection via cable, maybe the problem is in the WiFi router?
