Wireless cellular networks on the U.S. East Coast survived today's significant earthquake with only temporary congestion. Social networks like Twitter also worked as an alternative for staying in contact with those involved. Each time a major event like this happens, though, interest renews in the idea of dedicated emergency wireless networks to better cope with crisis events.
No doubt wireless networks have become essential to our daily lives, but are separate emergency networks really practical? Besides the large cost involved, it's still very difficult to build a wireless network infrastructure that can withstand all sorts of natural disasters and handle the load of large-scale emergencies. It seems more practical to focus on making our existing networks increasingly scalable and reliable.
