You probably have heard of the Serval Project before, but here is the gist in just a few words. Serval is an effort to allow mobile phones to communicate directly with each other, rather than having to go through a service provider’s relay antennas.
This is neat under any circumstances, but it is absolutely essential in times of disaster, when cell phone service is likely to be unavailable.
Oh yes – it’s open source and will be free.
Serval may well become a real game changer for mobile phone use…
