By "old" I mean about ten years ago, which I suppose is an eternity in the wireless networking universe - many cheap wireless extenders still use this approach to stay on the wireless router's channel, but you can push a signal just as well with a mesh system without all the negative effects of channel interference.
But it's not always about wireless repeaters, and it's possible that you'll have no choice but to set your access point to the same channel as other nearby wireless devices if the area is crowded. So let's look at some of your options and ways to mitigate the potential negative effects of multiple nearby access points sharing the same channel.
When two or more access points are using the same channel, even though their ranges overlap, there will be some degree of interference, depending on how close the access points are to each other. And I suspect that two main things can happen in this situation.

The most common consequence is co-channel interference, which kuwait telegram data essentially creates a line where each device has to wait its turn. In addition to adding latency when data is being transmitted fairly quickly, if a client device takes longer to transmit data, it will further slow down data transmission between all access points in the same area. Another type of interference is more sinister and is called adjacent channel congestion.
