In a disaster area cellular technology is often spotty due to massive power outages and people clogging the networks. Running ethernet cable to a series of hotspots would be great also, or using RF to propagate signals, but these things take time. If USAR teams have mesh networks built right into their phones I feel this would be extremely useful, especially in push-to-talk situations, receiving emergency notifications (fire/quake/volcano alerts, USAR needs to get out ASAP), comms back to hq etc. For me, this is an exciting and important area that can save lives and property.
