Yes. 1) 5GHz modules are more expensive. 2) 2.4GHz has channels 1 - 11 globally, with 12 and 13 in some countries. 5GHz only has channels 32 - 48 globally. Depending on country of distribution it then can support other channels too, but which channels are legal varies significantly. To support those, you need to know which regulatory area you are distributing to. So - additionally to HW being more expensive, you have to have different SKU for different regulatory areas, meaning production runs of different hw - more costs added. Limiting yourself to channels 32 - 48 to claim 5GHz compatibility will just cause you support pain & public image when people will complain your device does not really work with 5GHz. https://en.wikipedia.org/wiki/List_of_WLAN_channels#5_GHz_(802.11a/h/j/n/ac/ax) https://en.wikipedia.org/wiki/List_of_WLAN_channels#5_GHz_(8...
