We can't recommend this configuration. There is spectrum overlap between channel 1 and 5, 5 and 9, and 9 and 11. Transmissions in channel 1 will interfere with those in channel 5. Not completely, thanks to the design of the 802.11 wireless layer, but enough to significantly degrade the bandwidth available if they are physically coexistant. We instead recommend working with channels 1, 6, and 11, which theoretically have no overlap with one another. Given the consumer nature of the RF filters in WiFi units, you are best using only channels 1 and 11 if using two frequencies, to avoid cross channel interference. When testing in a dense environment (a classroom), I've seen WiFi units tuned to channel 1 receive packets transmitted on channel 6.
