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.
