Could mobile devices not be set up to pass along network packets, turning them into switches meaning that as long as a string of devices remained within a certain reach of each other, one singular network path could be formed between them
Creating a network with just mobile devices in close proximity of each other, like a p2p mesh? As long as you have some software running on each of the devices I dont see why you couldnt do something like this.
Most mesh networks have fixed routers that can be plugged into electrical outlets or solar panels. But mobile devices have only battery power, and if your device is constantly transmitting and receiving other people's data, its battery life is going to suffer.
Well, understandably, battery life isn't currently where it's at to handle such a p2p network, but the idea could be useful. If it was developed accordingly, there could be many uses from it.
Carrying internet connectivity across a city could be as simple as having one singular transmitter, which would connect to at the very least, one device. This device could pass the connectivity to other devices, which could pass it on to other devices, increasing the range, albeit, slowing down the overall speed.
It would also be useful for the sharing of resources between a private WAN.
I think anyway, I'm still new to the subject.
