For an archaeological project, I am tasked with figuring out some data routing problems.
The optimal case would be to be able to deploy a device (laptop or tablet) in the field that can advertise itself as a infrastructure access point. (We have severe equipment limitations due to battery requirements, and simply bringing a router along with us is a very secondary choice).
What packages do I need to install in ubuntu to get it to provide a local wireless network visible on Android phones? This network will have no presumed connection to the internet at large, but it must be able to accept incoming connection requests from android phones (who reportedly have significant problems seeing and connecting to ad-hoc networks). Optimally, this package should also provide for fairly trivial networking to other laptops running this package, but I suspect that that's a bit much to ask.
Routing to the internet should not be required, and does not need to be supported.
