The Capacity Crisis Myth , | |||
Anybody who warns of an unavoidable capacity crisis
on wireline or wireless networks is lying in order to sell you
something. That may be a blunt assessment to some, but it's the only
conclusion you can draw as we see time and time again that claims about
a looming network apocalypse (remember the Exaflood?)
violently overestimate future traffic loads and underestimate the
ingenuity of modern network engineers. Fear sells. Drink orange juice
or you'll die of cancer. Get more insurance or you're a bad family man.
Vote for me or lose your job and see your grandma deported. Pay $2.50
per gigabyte or face Internet brown outs. Be afraid. With the rumors of a looming landline network apocalypse disproven, you'll notice the doomsday predictions have shifted to wireless as we debate spectrum policy. Carriers like AT&T proclaim they're facing a capacity crunch that simply can't be avoided unless we do "X" (let them acquire T-Mobile, let them charge $50 per gigabyte, let them squat on oceans of spectrum). Research firms warn of a spectrum doomsday so they can sell LTE-Advanced hardware. The FCC nods dumbly throughout this cycle of hysteria because they want the revenue delivered by spectrum sales. As usual though, actually bothering to listen to and look at the data tells a different story. Nobody argues that spectrum is infinite, but buried below industry histrionics is data noting that there really isn't a spectrum crisis as much as a bunch of lazy and gigantic spectrum squatters, hoarding public-owned assets to limit competition, while skimping on network investment to appease short-sighted investors. Insiders at the FCC quietly lamented that the very idea of a spectrum crisis was manufactured for the convenience of government and industry. Now Dave Burstein this week bothered to actually look at wireless growth rates to (surprise surprise) find them to be completely reasonable: "Data consumption right now is growing 40% a year," John Stankey of AT&T told investors and his CEO Randall Stephenson confirmed on the investor call. That’s far less than the 92% predicted by Cisco’s VNI model or the FCC’s 120% to 2012 and 90% to 2013 figure in the "spectrum crunch" analysis...With growth rates less than half of the predictions, a data-driven FCC and Congress has no reason to rush to bad policy. 40% growth is still substantial, but wireless technology is improving at a breathtaking pace. LTE has about 10x the capacity of 2.5G and 4x the capacity of 3G. LTE Advanced, deploying beginning 2013 at Verizon, is designed for 10x the capacity of LTE. The reality is that the evolution of wireless and wireline networks has been an amazing act of engineering, one that quietly and consistently keeps pace with demand. While politicians wrangle, lobbyists distort the truth, and marketing departments pollute the discourse with fear for personal gain, network engineers quietly do their jobs and do it well. |
