20 MHz is absolutely correct. The wider the channel, the higher the risk that somewhere in its frequency range it will be hit with interference. Since 2.4 GHz is an especially crowded band, you want to avoid the risk of interference, even though it means that each mobile client will be stuck with less overall bandwidth for their connection
