WiFi networks 2.4 and 5 GHz, which offers better coverage?



Despite the large presence of networks WiFi running at 2.4 GHz, they are now increasingly talk of WiFi networks at 5 GHz, which drags a discussion of why one or the other, thus starting the war networks WiFi 2.4 and 5 GHz.

The problem of WiFi networks 2.4 GHz


First, let's talk about the 2.4 GHz WiFi (either in the standard that is -802.11b, 802.11g, 802.11n-), which becomes the most compatible, since virtually all devices have secured this band.

Allow to operate through 13 channels, but the saturation of the channels (given the amount of home routers acting under this frequency) starts to become a problem involved in interference between neighbors, between devices (mice, wireless keyboards etc.) or even waves of certain appliances such as microwave.

Such interference can lead to problems of errors, saturation limited scope or speed, if the frequency is really saturated our area concerned. Thus, we may experience loss of connection, low coverage or not rentabilizamos see how the contracted speed.

Advantages and disadvantages of the 5 GHz WiFi.


Seeing the problems that arise, then begin to market to a greater extent compatible devices 5 GHz frequency, which at first were not so regarded by cost issues (they are more expensive than 2.4 GHz).

Given that we have changed the frequency, decongestion our favor, allowing networks to be less emitting at this frequency interference are much lower.

Going into greater detail, these WiFi allow us to send data on multiple channels simultaneously, resulting in we can get a much higher speed. In addition, each channel has 20MHz, by 80 in total 2.4GHz frequency.

However, the higher the frequency, the lower is the range that is covered, in this aspect clearly winning the 2.4 GHz.

In addition, WiFi 5GHz solid objects transgress worse compared to the others, something to consider as the distribution of our home and the number of walls to cross.

The fact that not the most extended frequency can also lead to incompatibilities until the frequency of 5 GHz to settle in the market, resulting in another drawback at least in the short term.

WiFi 2.4 GHz and 5 GHz: Which do I stay?


When opting for one or the other, the first question we must answer is:

Are all devices to be connected to our network are compatible with 5GHz networks?
If the answer is no, the solution is clear: choose WiFi networks at 2.4 GHz but not only in that case will choose, but also those who need good coverage and dispongamos an organization of our home that presents many obstacles. the waves.

Conversely, if this is not a problem, and we have compatible devices, we can opt for the WiFi 5 GHz, especially when we want to distribute streaming, so we will need a higher speed, which gives us this frequency.
