Be careful there. The channels do overlap which means that if one device uses ch 1 and the other ch 2 they both see each other as a high noise source but do not recognise the other as a valid transmission. Therefore they do not wait for the transmission to finish before transmitting them self. Net result is a worse result for both parties in most cases. As a picture says more than words have a look at https://en.wikipedia.org/wiki/List_of_WLAN_channels. This is why the advice is to only use channels 1,6,11 (14 is not usable in Australia) and put competing devices onto the same channels still so they recognise each other to make best use of the available capacity. There are cases where it helps to cause interference, e.g. if a device uses high bandwidth while having poor reception (e.g. mobile playing video) it occupies the channel almost 100% not leaving much room for any other user. Causing interference there means that that device will fail to get a usable connection and therefore freeing the capacity. However this backfires if your AP and clients don't have a fairly good reception because the competing AP/clients will do the same to your clients/AP.
