I want to make wireless communication between android phones without using SIM cards and without internet.
I want it to be such that:
① it must be valid for more than 5 km.
② I need to receive the information at the second phone in a manner such that I can use this information in a Prearranged program in the second phone, i.e I need the information for controlling purposes, not for displaying purposes.
For example: to send numbers from the first phone and receive it at the second one, then doing operations at this numbers, such as adding and subtracting automatically by prearranged program.
Is anyone know any way to do this, even if by using an external module with the phone.
