The last issued of Ericsson's ON magazine has an article about coordination of field workers.

when police, fire, rescue and medical personnel can not talk to each toher on the same network, accidents can quickly become tragedies.

Why do I blog this? because it's interesting to strengthen the fact that communication and cooperation are intricately related fo foster better coordination. Now specific applications are not just research project but are applied in real contexts as described in the paper.
