Is There Co-Channel Interference in Wi-Fi?

2.4 gigahertz is a lower frequency and it propagates farther, but there are not as many channels that we could use in 2.4. In five gigaherz, there's a lot more channels to work with. But think about co-channel, like having a meeting in the office, right? How many of you have had two different meetings in the same room? It doesn't happen. No one does that.
