Consumer demand is creating the need, Gorenberg said, adding, "I do
believe there is a spectrum crunch. It's due to this wonderful
situation where demand is growing off the hook because...we're
becoming a mobile-first society."
This is forcing technologists to think more holistically about
bandwidth and how to allocate services.
"You're seeing the LTE camp [emerging] but by the way you're seeing
tremendous offloading onto Wi-Fi, which is what's keeping up" with
demand at the moment, he said.
Gorenberg said a combination of macro cells and micro cells will also
contribute to meeting demand. He referenced this week's announcement that
AT&T plans to spend
$8 billion to update its 4G LTE wireless network.
The deal "included 10,000 macro cells and 40,000 small cells,"
"We'll see HetNets, carrier-driven LTE-based macro and small cells
all working together," Gorenberg said.
And you're going to see the idea of more open sharing, like the
spectrum access system, he added.
He noted that it's not just a challenge in the United States: The
European Union is examining the notion of sharing not only federal
bands but commercials bands.
The Federal Communications Commission has paved the way for
incentive auctions in 2014, in which broadcasters could
choose to sell their spectrum. The incentive auctions are intended
to free 300 MHz of spectrum by 2015 and 500 MHz by 2020.
