ICS stands for Internet Connection Sharing
http://support.microsoft.com/kb/306126
WifiRouter , WMWiFi or ICS Control are the software you use on your Mogul to share the internet to your PC or Laptop
I never used WMWIFI, however, I used both wifiRouter and ICS control before. IMO, WifiRouter is easier to use and ICS control got more advance feature.
Hope that help you.
