"Et problem med 2,4 GHz-frekvensbåndet er, at rigtig mange producenter anvender det. Ikke kun netværksudstyr men også eksempelvis radiostyrede biler. Det betyder, at der er stor trafik og trængsel på båndet. Derfor har der været behov for en ny trådløs netværksstandard," fortæller Lasse Haizmann.

og det gælder også Bluetooth og microovne, og som du selv har oplevet trådlæse telefoner

The primary difference between the 2.4 GHz and 5GHz wireless frequencies is range as the 2.4GHz frequency is able to reach farther than the 5GHz frequency. This is a result of the basic characteristics that waves attenuate much faster at higher frequencies. So if you are more concerned with the coverage, you should select 2.4GHz rather than 5GHz.
The second difference is the number of devices on the frequencies. 2.4GHz suffers more interference than 5GHz.
The older 11g standard only uses the 2.4GHz frequency, majority of the world is on it. 2.4 GHz has fewer channel options with only three of them non-overlapping, while 5GHz has 23 non-overlapping channels.
A lot of other devices are also on the 2.4 GHz frequencies, the biggest offenders are microwaves and cordless phones. These devices add noise to the medium that can further decrease the speed of wireless networks.
In both aspects, choosing to deploy on the 5GHz frequency is the much better option as you have more channels to use to isolate yourself from other networks and there are far fewer interference sources.
