I have a need to be able to have say 4 iPads communicate with each other in real time. The issue is there is no Internet so it cannot be done thru the cloud. My idea is to create an ad hoc wireless network with a router. Then connect all the iPads to that access point. The iPads would need to be able to share data in real time. Everyone would basically be looking at the same screen. They could all input changes to the data on the screen a d see those changes in real time. This could be a dedicated app designed to do this or even just the ability to all view an excel spreadsheet. Ideally we would only have the iPads but if needed we could put 1 laptop on the network to act as a server and main data entry point. I am not an IT guy and do not understand all the ways information is shared or pushed out to tablets. The system is intended for use on a ship at sea thus the reason for no Internet or cloud options. If any or my terms are misused or you need more info let me know. Also if there is a better title for this to help other find this thread in the future please let me know.
