Which means that using WiFi shouldn’t be the identical in all components of the world.

Why is that this occurring? To reply that query, you could know how wifi networks work. Like a radio, for instance, additionally they transmit data via waves. Which means that there could also be interference. It’s the identical as if an FM radio station is on virtually the identical frequency as one other channel.

The rationale sure channels can’t be utilized in some nations is as a result of they could intrude with satellite tv for pc radio waves. That is the case of channels 12 and 13, for instance, in the US. There they don’t enable them for use in a basic approach to forestall frequencies from leaking and creating issues.
