When
a natural disaster strikes, whether it’s a hurricane, wildfire, tsunami, or
earthquake, they all have devastating repercussions. Among the effects caused
by these tragedies are the family members desperately trying to reach their
loved ones to see if they were alright. When Hurricane Sandy hit the northeast
coast, the FCC reported that nearly 25% of the cell towers had been knocked
out. USA Today noted that the limited
technology and access to satellite networks inhibited the rescue efforts.
The
2010 earthquake in Haiti also showed how not having a well-developed wireless infrastructure
can be detrimental. Haitian engineer, Charles-Edouard Denis, spoke with IEEE Spectrum about the impact of the
earthquake on Haiti’s cellular infrastructure.
“Right after the earthquake, the only
company that was still working was Haitel, but its network was quickly overloaded.
It remained operational mostly because it utilized almost exclusively 30- to
60-metertowers that are built to withstand hurricanes and earthquakes. Digicel
and Comcel were not operational at all, and since between the two they have
more than 3 million subscriptions, a lot of people could not communicate,”
Denis said.
“Most of the people trapped under the
rubble were trying to use their phones to call family members to let them know
where they were, but the service was not available, and no one came to help
them. At a quarter to five in the afternoon, some people were not at work. They
left early to either stop at a friend's house or at a supermarket. So family members
had a hard time identifying the location of their loved ones and therefore
could not help. Since Digicel has more than 2 million subscribers, this lack of
telephone service caused a lot of deaths,” Denis explained.
Not only is there a need for more
spectrum, because the demand for mobile spectrum is surpassing the available
supply, there is a need for a stronger wireless infrastructure that is able to
withstand strong winds in order to better assist people during natural
disasters.
Darrell
West, director of the center for technology innovation at the Brookings
Institution, told USA Today
that, “We need to make sure that there are strong backups because mobile has
become integral to people's lives, and in a time of disaster sometimes it's
their only lifeline to the outside world."
