Lightbulb Mesh cell phone network = Walkie Talkie

Good day every one

Really long time ago I had an idea! But few other people had the same idea Other projects use WIFI for a connection but I am talking about actual cellular network (GSM).

The idea is: add a feature to an open source cell phone to be able to make calls without a network provider. The design will look like a computer mesh network.




Think of every cellphone like a Cisco network router with dynamic routing enabled.
Each phone will be aware of the presence of other phones and will have route table to every single one. There is no centralized server sort of like peer to peer.

When a user wants to make a call, then the cellphone will display the devices that are online and can be reached.



Look at the picture above and notice that there are more than one route to each device. Having many phones like that will increase the coverage!



Now does anyone know how to implement a such thing?
Maybe use android phones? Since OS is open source maybe it is possible to add this into it?
What do you think?

I dont think its practically feasible..
And moreover You cant use Service Provider's cellular network just like that ( and that also free)

I think Serval Mesh is what you want

EDIT : oups, already in your list...

The idea here is to create an independant cellular network, using only the GSM equipment of phones, without using the service provider network.

sounds like a great idea, i would want something like this for sure. but the only down side is that you could only make a call for as far as the network broad casts which means in a small town it would really suck.

Nice idea but very costly.

That's an interesting concept, but from what I understand, to make a call without an operator, both phones will have to be connected to the mesh network, right?
That situation would be rather rare, it's like making a video call between two iPod touch (that don't have a cellular network). If the other side is not connected to WiFi at the moment, the call won't go through.
Also something to think about is the battery life. If other people's calls would be routed through your phone all the time, it would drain the battery very fast.

The unfortunate bit to this idea is that, barring hardware,privacy, and feasibility constraints...If you implemented such a network, there would be no guarantee that you would be within the bounds of the network at any time. With current providers, there are rough estimates as to the coverage area that are fairly accurate, depending on exact conditions.

With this system, if a couple people in your neighborhood leave the town or country, suddenly, you have no service, or slow service.

It'd just fluctuate too much and wouldn't be reliable.

Phones hardware and closed-source software isn't designed to ad-hoc networking. IMO the closest available solution for that is this:

It is definitely an interesting idea, sorta makes me thing of "Ad-Hoc Networking for Phones". The only problem is, the phones would be limited to calls in their "network", so if you had 3 people in a desert, they could call each-other, but would be otherwise sunk

The problem though lies in that it would basically use your phone to power everyone else's phone service, and that would mean that your precious phone would be crunching data all day long, and eating batteries like they are going out of style (Not that it doesn't already).

So while in-theory you could get cellphones to all link up in a row and make a cell-to-cell network, latency would increase exponentially the more phones you have to "hop", and battery life would decrease.

Good thinking, but you would be better off starting your own cell network, and not charge outrageous prices. I am sure that we would all be happy to switch if you had good coverage and reasonable service
