Wi-Fi channel selection is crucial in cases like this. Reason 2: Adjacent-Channel InterferenceĪdjacent-channel interference happens when clients on overlapping channels talk at the same time. That’s basically what co-channel interference is, which is why Wi-Fi routers take turns and politely wait for one another to finish. The chances are that multiple kids started shouting at once and nobody could hear anything properly. Think back to when you were in elementary school and your teacher asked the whole class a question. Instead, it’s a result of Wi-Fi routers doing their best to give one another room to transmit data. This type of Wi-Fi interference isn’t actually electromagnetic interference. Therefore, the more devices the longer the wait time. In networks where devices take turns to talk, it takes time for each of them to wait for their turn.
