Almost immediately after Monday's tragic bombings at the Boston
Marathon, the city's cellular networks collapsed. The Associated Press
initially reported what many of us suspected, that law enforcement
officials had requested a communications blackout to prevent the remote
detonation of additional explosives. But the claim was soon redacted as
the truth became clear. It didn't take government fiat to shut down the
cellular networks. They fell apart all on their own.
As cell service sputtered under a surge of calls, runners were left in
the dark, families couldn’t reach loved ones, and even investigators
were stymied in making calls related to their pursuit of suspects.
Admirably, Boston residents and businesses responded quickly by opening
up Wi-Fi hotspots to help evacuees communicate with loved ones.
But most, even the super-connected elite, were knocked offline. As his
Twitter followers know, it took
Dennis Crowley, a Massachusetts native and CEO of New York City-based social
network Foursquare, an hour to reunite with his fiancé and family, who were
scattered around the finish line as the bombs went off. Their reunion was
coordinated by a handful of SMS messages he was able to squeeze through the
crippled network. He also reported helping several stunned senior citizens
discover the value of their own phones' texting functions for the first time.
We shouldn't be surprised by the collapse of Boston's cellular networks. The
same thing happens every time there is a crisis in a large city. On an average
day, Americans make nearly 400,000 emergency 911 calls on their mobile phones.
Yet during large-scale crises this vital lifeline is all-too-frequently cut off.
The culprit is usually congestion. During a disaster, call volumes spike and
overwhelm the over-subscribed capacity of wireless carriers' networks. On
September 11, 2001,
fewer than 1 in 20 mobile phone calls in New York City was connected. The
same thing happened after the August 2011 earthquake that shook the East Coast.
And on Monday, in Boston.
But, as we learned in the aftermath of Hurricane Sandy, wireless carriers
have also neglected to harden their networks against extended losses of
electrical power. Thousands of towers were knocked offline in the New York
region alone when backup batteries failed. Yet as a member of Governor Andrew
Cuomo's NYS Ready Commission this fall, I was stunned to learn that wireless
carriers had never formally discussed plans with the region's electric utilities
to restore power to cell sites after a major disaster.
The loss of vital wireless communications during disasters is all the more
dismaying because it is largely preventable. After 9/11 a system was put in
place to give government officials priority access to cellular channels during
periods of high demand. (Though it requires pre-registration and a special code
be used when dialing). In the wake of Sandy, New York Senator Charles Schumer
called for stricter federal oversight of backup power and landline network
connections for cell sites. Yet these reforms have been stalled by industry
lobbying. Lacking a redundant cellular system, Americans will continue to resort
to the century-old technology of amateur radio for lifeline communications
during and after large disasters. In Boston, this technology is still widely
used during the marathon because of past experience with cellular traffic jams.
With over 320 million active wireless subscriber connections, Americans are a
fully untethered people. Our smart phones keep our complicated lives
choreographed across the sprawling metropolitan areas we inhabit. Psychologists
and sociologists have found that we think of these devices as extensions of our
bodies and minds. In Boston, this was all too apparent. Even when runners, whose
mobile batteries were drained after the long run, could locate a phone, they
couldn't recall what numbers to dial, having long ago given up memorizing phone
numbers in favor of their smart phone's electronic address book.
Despite our utter dependency on cellular networks, the industry has failed to
act substantially to improve the reliability of these systems. While it is one
of the most vibrant sectors of the economy — AT&T Wireless, for instance, had
its most profitable quarter ever in the months before Sandy — and invests tens
of billions annually in network expansion, somehow the cost of greater
reliability has not been deemed a priority. These companies have sold American
consumers a digital lifeline without honoring their responsibility to assure it
works at our time of greatest need.
Even if we do choose to engineer a better cellular grid, the more disturbing
revelation of the Boston breakdown is the speed with which we've come to accept
the shutdown of cellular networks as an acceptable exercise of law enforcement
power. This is a tactic pioneered in Egypt by an autocratic government in its
death throes to shut down mass protests. It should never be deployed in an
information-based society that has become utterly dependent on wireless
communications for every aspect of its social, economic, and political
functioning.
Seeing our cellular networks as the launch pad for the next wave of terror
attacks is self-defeating. Mobile phones do make effective remote controls for
detonation, but so do landlines. Telecommunications networks have been used to
plan and trigger attacks as long as we've pulled telegraph and telephone wires
through our cities. (In 1972, the Mossad assassinated the PLO's kingpin in
France using a remotely detonated desktop phone bomb.) But we never shut down
the phone system to stop a single call. Besides, it was too hard to do quickly.
Ironically, the same technological advances that have made mass cellular
communications possible now allow us to throw a single kill switch for an entire
network. We can now self-inflict additional damage by a panicked decision to
neuter our own capacity to respond. No one denies the need for law enforcement
to have the tools it needs to stop an attack. But there are more precise ways to
do that.
The time to stop treating our cellular networks as an afterthought in
preparedness, as expendable casualties during crises, is long overdue. In fact,
they are the key to getting first responders to where they need to be, and an
essential tool for resilient responses by citizens in the hours and days after a
major disaster. The cellular industry has enjoyed the benefits (and profits) of
access to public radio spectrum. With that access now comes enormous
responsibility. We can't afford a communications infrastructure that works only
when we don't really need it.
