I am trying to figure out a way to slave three cellphones to my current Note 8. I am attempting to do this by having only these four phones in the network and not connected to the internet or a router. The purpose of this is to use my phone to access the cameras on the slave phones. I need about 100m between the master and slaves. The only way I can think of is by using the on-board WiFi radios to establish the network.
Any ideas on how or if this kind of thing can be accomplished?
