Cellular Activity
When mobile phones threaten security, it’s time to ‘decellerate’

This just in: There are now more
cell phone users on the planet
than wearers of shoes. That
random yet eye-opening nugget comes
courtesy of WikiAnswers, so consider
the source, but still: more than shoes?
It’s no newsflash that we now inhabit
a cell-centric world. The increase
in the number of mobile phones in the
past decade has been exponential and
very visible (and, if you frequent some
of the same stores, restaurants, trains
and sidewalks as I, you can attest it’s
also been a very audible proliferation).
Cell users are literally everywhere you
turn. And too many of them have obnoxious
ringtones.
Celler’s Market
According to the International Telecommunication
Union, which is the
United Nation’s specialized agency for
information and communication technologies,
there are, as of press time, 5.9
billion mobile-cellular subscriptions.
That’s an impressive number in itself,
but it’s even more remarkable considering
the world’s population is, also at
press time and according to the U.S.
Census Bureau, 6.9 billion. (The number
of people who at least wear foot
coverings is 4.5 billion, as estimated by
the folks at Wiki.)
As far as inventions go, those numbers
put the cell phone right up there
with the wheel or, well, shoes. Wireless
technology continues to transform lives
and to become ever more integrated
in—if not essential to—the human
condition. And for the most part that’s
an entirely good thing.
The benefits of cell phones in emergency
situations are undisputed, and,
in this age of multitasking, no one can
argue against the devices’ advantages
in terms of scheduling, connecting
and saving time. They provide a convenience
almost unheard of 10 years ago.
Yet, cells also have their downside,
and as those in the security industry
know, annoying ringtones and users
who insist on conducting personal
conversations in public places (loudly)
are the least of it. In the wrong hands,
mobile phones can too easily be used to
breach security, threaten safety or even
commit crimes. When any of those outcomes
are distinct possibilities, there
arises the need to know where the devices
are, to be able to track them and
to prevent their use. And because this
need is more prevalent than one might
at first think, the business of cell phone
detection has relatively quietly become
an industry all its own.
Phone Homing
If you consider it, there are any number
of places that commonly have “No
Cell” zones. Courtrooms, classrooms,
conference rooms, commercial jet cabins
and movie theaters typically have
policies either prohibiting or limiting
wireless use. And if you’ve frequented
any of those rooms in the past year, you
know that in all of them people just as
typically ignore those policies—some
surreptitiously, some flagrantly.
Scott Schober, president and CEO
of Berkeley Varitronics Systems (www.
bvsystems.com), has sold cell phonedetection
units to all of the above venues,
and he said the demand at such
locations is on the rise. His company,
based in Metuchen, N.J, specializes
in designing and manufacturing the
units. Some of the devices are handheld,
some are made for mounting on
walls and at entrances, and still others
are custom-crafted for countersurveillance,
made to fit covertly inside water
bottles or hollowed-out books. All the
models home in on the RF signature
of nearby cell phones in either standby
or active voice, text or data-transmission
mode, enabling the operator to
precisely pinpoint where the wireless
activity is happening.
“Everybody has mobile phones
these days, and so people can do videos
and take pictures, people can listen in
on conversations, and in a lot of environments
that can be very dangerous—
it can be a compromise of security,”
Schobel said. “As phones get smaller
and smaller, it gets harder to enforce
the no-cell environments; people can
smuggle them in in all different ways.
We’ve been effective by the fact that our
tools are lower cost, and they home and
find the phones and get them out, one
at a time.”
Cells within Cells
Where most of the mobile phone smuggling
is happening these days is at the
nation’s 8,000-plus jails and prisons,
where inmates are willing to pay corrupt
guards upward of $500 for a single
phone rather than use the facility’s builtin,
monitored, one-way, collect-call-only
landlines. Prisoners then use the contraband
cells to contact outside gang
members, intimidate witnesses, relay
information on transportation of other
inmates and otherwise conduct criminal
activity from inside prison walls. Schobel
said that at this point roughly half
of his cell-detection business is centered
on correctional facilities.
“The problem is at epidemic proportions
in these places,” he said. “It’s
not that there are five or 10 phones
in a facility. We’re talking in California
prisons alone, we’ll find probably
10,000 to 15,000 phones just this year.
It’s staggering.”
The other major areas for wireless
detection today include installments at
some of the more than 10,000 federal
facilities in the nation, most of which
are designed to be either highly secure
or outright SCIF (Sensitive Compartmented
Information Facility)-grade
secure. By design, access to SCIFs is
severely limited, and all the activity,
conversation and data inside these enclosed
locations is supposed to be secure
and classified and thus no place
for a mobile phone.
Because Berkeley Varitronics’ line of
detectors also home in on GPS trackers,
the devices are being deployed for
border security and drug enforcement.
Schobel said one of the most rewarding
uses of the equipment, though, is
as search and rescue tools for finding
people who are lost or, say, trapped
under rubble after a building collapses.
It is, he said, another of the upsides involved
with virtually everyone carrying
a phone.
