On a daily basis for the past year, wireless carriers have been scrambling to increase their network capacity in order to
provide faster mobile services for their subscribers. However, that's easier said than done, and this represents a major
challenge for them, since wireless spectrum is controlled by the Federal Communications Commission, and is becoming extremely
rare.
But now, the FCC is making an effort at using the small existing spectrum segment between some TV channels. Sounds like
easy to do, but it really isn't.
The FCC said a few days ago that it opened up the light spectrum that sits between individual television channels numbered
1 through 51. Wireless communications in that so-called white segment will be permitted as of January 26, 2012 in a testbed
location and will be opened up across the U.S. in the following months.
Broadcasting in that white segment means that a company like AT&T Mobility could deliver mobile services say between channels
5 and 6, for instance, and Verizon Wireless between channels 6 and 7, and so on and so forth for the other companies.
The problem is that this gives them just a little extra capacity boost to give their customers faster service, but it still
won't be enough for the current explosion in smartphones and tablets which should continue well into 2015.
The FCC announcement comes as mobile service providers are facing a spectrum crunch crisis that has already begun to
reshape the wireless industry in more ways than one.
As tablet and smartphones sales have soared over the past several years, consumers' demand for data and voice services has
grown exponentially. All that data is taking up a growing amount of wireless spectrum, and carriers are now simply running out
of airwaves to place all that data into.
The FCC has repeatedly said that a current spectrum surplus of 225 MHz will become a deficit of 275 MHz (or more) by 2014.
That's why the agency is committing to freeing up 500 Megahertz of additional wireless spectrum over the next ten years.
But there's the catch-- that process also includes voluntary auctions by a patchwork of television stations across the U.S.
that currently hold but aren't using their spectrum.
And the problem is that most of them aren't willing to let it go, not for free that is. And some wireless industry observers
are expecting that the spectrum is now a very valuable commodity, and that prices could soar very fast.
Still, the FCC is trying to get enough of it to just get by, at least for now. And those so-called television white spaces
are a part of that effort.
"Unused wireless spectrum between television stations represents a valuable opportunity for provision of broadband data
services in our changing wireless landscape," said FCC Chairman Julius Genachowski in a statement.
But it's far from being a perfect solution. The white space spectrum will actually be unlicensed, which means that wireless
carriers can't use it exclusively. But like Wi-Fi, which also operates in unlicensed spectrum bands, wireless providers will
eventually be able to provide their customers access to a white spaces network hotspot in order to offload some traffic from
their own networks.
For now, the idea is just a concept and still needs to be tested. Some in the wireless industry aren't still sure that
this will work however, since there could be some technical issues and other considerations that could complicate things.
Additionally, new mobile phones and tablets will need newer chipsets, and the FCC will only open up white spaces for the
time being in Wilmington, N.C., as it tries to repair a bug that could result in some interference with wireless microphones,
which also use white space to send signals to speakers.
And while all of this is happening, wireless carriers aren't just sitting on their hands either. They've attempted to
limit customers' use of their mobile networks by introducing tiered rates, which charge more by the gigabyte. That has
effectively made mobile phone bills go up for many heavy users.
The good news for consumers is that the FCC is aware of the issues and is trying to work out a solution to free up more
bandwidth for mobile communications.
"There are big scarcity issues with wireless spectrum," said Rod Dir, CEO of Spectrum Bridge, the company approved by
the FCC to manage the registry of devices that operate in white spaces. "This provides additional bandwidth in the market,
not just for cellular carriers, but also for other wireless providers."

After the news of Carrier IQ's numerous security and privacy issues that were recently discovered, it's now getting
clearer than ever that most mobile phone users don't have a clue of what's going on inside their smartphones. Some anti-virus
firms have already begun releasing Carrier IQ's detection apps for the Android operating system, but
only after the controversial software became a talking point on Capitol Hill.
Additionally, more than a month after a security researcher first discovered it while working on a HTC EVO smartphone,
it now looks like this issue won't go away anytime soon.
For its part, BitDefender has released Carrier IQ Finder, an app that identifies the presence of the controversial
mobile diagnostic tool, following Lookout's earlier release of a similar tool called Carrier IQ Detector.
And it gets worse. Users don't have any control over the situation and are totally at the mercy of Carrier IQ.
Carrier IQ's sudden jump into the national spotlight ignited widespread confusion and anger. On Dec. 2nd, the
U.S. Senate and former late-night funnyman Al Franken has called on Carrier IQ to explain why its diagnostic
software, buried in the bowels of 141 million smartphones, isn't a massive violation of U.S. wiretap laws.
An Android mobile application developer has wrote about what he thinks could be a conclusive proof that
millions of smartphones all over the globe are secretly monitoring key presses, geographic locations, and received
messages of its users. If true, this is a serious security risk, and one that needs to be rapidly addressed and
corrected by all phone makers.
The whole thing started on November 30 after Android developer Trevor Eckhart released a 17-minute YouTube video indicating that the
little-known application was sending everything you do on your phone back to your carrier, including what websites you visited,
what your texts say and what keys you press at any time.
Making matters worse, Carrier IQ and the various wireless operators that are involved actually increased the anxiety level
by staying very quiet about the whole issue. They refuted the charges that they logged or tracked keystrokes, but couldn't
immediately explain everything the software --intended to help carriers troubleshoot network problems-- was actually doing.
"We're as surprised as anybody to see all that information flowing," said Andrew Coward, Carrier IQ's director of marketing, soon
after Eckhart posted his YouTube video. Three weeks later, Carrier IQ and its customers have finally finished dissecting their
products. We now mostly know how Carrier IQ works, how it got there, and what its purpose is. Well kinda, sorta that is.
It turns out that those initial statements were mostly right (!) Carrier IQ sends innocuous data from your phone back to
your wireless carrier like when and where you sent a text message, when and where a call is dropped, and what apps are draining
your battery. That information helps carriers find problems. But 'what' problems, exactly?
Here's what it doesn't do: It doesn't send your keystrokes, the content of your text messages or what websites you visit
to your carrier. Huh?
The log exposed on Eckhart's video, captured on an HTC EVO 3D from Sprint, turned out to be a specific, one-off issue.
Carrier IQ and a security consultant, Dan Rosenberg of Virtual Security Research, determined that HTC had turned on a
debug logger that should have been left off by default. As a result, the Carrier IQ app was temporarily storing everything
a user did on the phone. The software maker said it is working with HTC to fix the issue.
At any rate, Carrier IQ is installed on an estimated 155 million or more mobile devices, but the specific problem Eckhart
uncovered appears to be limited to a small handful of devices, although he still can't be 100 percent sure of that for now.
So was all the mayhem over nothing? Not really. "I want to make it clear that just because I do not see any evidence of
evil intentions does not mean that what's happening here is necessarily right," said Rosenberg.
"Consumers still need to be able to opt out of any sort of data collection," he said. "There needs to be more transparency
here. Right now, there's almost none."
One option would be to require government or third-party oversight. Even Carrier IQ suggested that some regulation would
be necessary and the company hinted that it is all for it.
Each wireless carrier it works with chooses to gather different information from their customers' phones, and the scope
varies a lot, further compounding the problem. But cell phone owners have been largely left in the dark about what carriers
are collecting, and that's another issue as well.
"The way I see it, Carrier IQ raises a lot of questions for the whole wireless industry and not only just for itself,"
said Andrew Coward, Carrier IQ's director of marketing. "It puts in doubt the trusted relationship between a consumer and his
wireless carrier, among other things."
And this is a story that is becoming all to familiar as well, and has been brewing for a while. Mobile handset makers and
wireless carriers keep tripping over security holes and privacy bugs that leave customers' movements and communications more
exposed than anyone had ever realized just a year or two ago.
In April 2010, data researchers discovered that the iPhone appeared to be recording users' every move and sending the
information back to Apple. IPhone users became furious. The question is: was Carrier IQ involved as well at that time?
Nobody seems to know for sure, and at that time, Apple didn't comment for about a week, but finally posted an explanation
on the company's website. The iPhone was not technically recording users' locations. Rather, it was logging nearby Wi-Fi
network locations to assist with GPS tracking. Really? Wow!
Still, the company admitted that it catalogued and stored a lot more data than it ever intended. Apple eventually fixed
the problem with a software update in iOS.
On any given day, Smartphones hold a boat load of information about their owners, and they're constantly transmitting
some of that data to and from the handset's manufacturer, the wireless carrier and the companies that design the phones'
software.
Conclusion-- unless those so-called data transfers become more transparent to all mobile phone users, these blow-ups
will likely keep happening, and we will hear and read a lot more about them. As always, Wireless Industry News will keep
you posted on this and other news that affect you.
