KOERNER<br>Feb 18 2014<br><<a href="http://www.wired.com/threatlevel/2014/02/spectrum-warfare/" target="_blank">http://www.wired.com/threatlevel/2014/02/spectrum-warfare/</a>><br><br>An electromagnetic mystery in northern Iraq changed the course of Jesse Potter’s life. A chemical-weapons specialist with the US Army’s 10th Mountain Division, Potter was deployed to Kirkuk in late 2007, right as the oil-rich city was experiencing a grievous spike in violence. He was already weary upon his arrival, having recently completed an arduous tour in Afghanistan, which left him suffering from multiple injuries that would eventually require surgery. In the rare moments of peace he could find in Kirkuk, Potter began to contemplate whether it was time to trade in his uniform for a more tranquil existence back home—perhaps as a schoolteacher. Of more immediate concern, though, was a technical glitch that was jeopardizing his platoon: The jammers on the unit’s armored vehicles were on the fritz. Jammers clog specific radio frequencies by flooding them with signals, rendering cell phones, radios, and remote control devices useless. They were now a crucial weapon in the American arsenal; in Kirkuk, as in the rest of Iraq, insurgents frequently used cell phones and other wireless devices to detonate IEDs. But Potter’s jammers weren’t working. “In the marketplaces, when we would drive through, there’d still be people able to talk on their cell phones,” he says. “If the jamming systems had been effective, they shouldn’t have been able to do that.”<br><br>A self-described tech guy at heart, Potter relished the chance to study the jammers. It turned out that, among other problems, they weren’t emitting powerful enough radio waves along the threat frequencies—those that carried much of the city’s mobile traffic. Once the necessary tweaks were made, Potter was elated to witness the immediate, lifesaving results on the streets of Kirkuk, where several of his friends had been maimed or killed. “To see an IED detonate safely behind our convoy—that was a win for me,” he says. It was so thrilling, in fact, that when Potter returned from Iraq in 2008, he dedicated himself to becoming one of the Army’s first new specialists in spectrum warfare—the means by which a military seizes and controls the electromagnetic radiation that makes all wireless communication possible.<br><br>It is well known that America’s military dominates both the air and the sea. What’s less celebrated is that the US has also dominated the spectrum, a feat that is just as critical to the success of operations. Communications, navigation, battlefield logistics, precision munitions—all of these depend on complete and unfettered access to the spectrum, territory that must be vigilantly defended from enemy combatants. Having command of electromagnetic waves allows US forces to operate drones from a hemisphere away, guide cruise missiles inland from the sea, and alert patrols to danger on the road ahead. Just as important, blocking enemies from using the spectrum is critical to hindering their ability to cause mayhem, from detonating roadside bombs to organizing ambushes. As tablet computers and semiautonomous robots proliferate on battlefields in the years to come, spectrum dominance will only become more critical. Without clear and reliable access to the electromagnetic realm, many of America’s most effective weapons simply won’t work.<br><br>The Pentagon failed to foresee how much the wireless revolution would alter warfare.<br><br>Yet despite the importance of this crucial resource, America’s grip on the spectrum has never been more tenuous. Insurgencies and rogue nations cannot hope to match our multibillion-dollar expenditures on aircraft carriers and stealth bombers, but they are increasingly able to afford the devices necessary to wage spectrum warfare, which are becoming cheaper and more powerful at the same exponential pace as all electronics. “Now anybody can go to a store and buy equipment for $10,000 that can mimic our capability,” says Robert Elder, a retired Air Force lieutenant general who today is a research professor at George Mason University. Communications jammers are abundant on global markets or can be assembled from scratch using power amplifiers and other off-the-shelf components. And GPS spoofers, with the potential to disrupt everything from navigation to drones, are simple to construct for anyone with a modicum of engineering expertise.<br><br>Stateless actors aren’t the only—or even most troubling—challenge to America’s spectrum dominance. The greater an opponent’s size and wealth, the more electromagnetic trouble it can cause. A nation like China, for example, has the capability to stage elaborate electronic assaults that could result in nightmare scenarios on the battlefield: radios that abruptly fall silent in the thick of combat, drones that plummet from the sky, smart bombs that can’t find their targets. The US may very well never engage in a head-to-head shooting war in the Far East, but the ability to effectively control the spectrum is already becoming a new type of arms race, one that is just as volatile as the ICBM race during the Cold War—and one that can have just as big an impact on global diplomacy.<br><br>The American military is scrambling to develop new tools and techniques that will help it preserve its electromagnetic edge. But that edge continues to shrink by the day, and very soon our inability to completely control the spectrum might result in a different kind of war.<br><br>[snip]<br><br>Dewayne-Net RSS Feed: <<a href="http://dewaynenet.wordpress.com/feed/" target="_blank">http://dewaynenet.wordpress.com/feed/</a>><br><br><br><o:p></o:p></p><div style='border:none;border-top:solid #CCCCCC 1.0pt;padding:4.0pt 0in 0in 0in'><table class=MsoNormalTable border=0 cellspacing=0 cellpadding=0 width="100%" style='width:100.0%;background:white'><tr><td style='padding:0in 0in 0in 0in'><p class=MsoNormal><span style='font-size:7.5pt;font-family:"Helvetica","sans-serif";color:#333333'><a href="https://www.listbox.com/member/archive/247/=now" title="Go to archives for ip"><span style='color:#669933;text-decoration:none'>Archives</span></a> <a href="https://www.listbox.com/member/archive/rss/247/22720195-c2c7cbd3" title="RSS feed for ip"><span style='color:#669933;text-decoration:none'><img border=0 id="_x0000_i1025" src="https://www.listbox.com/images/feed-icon-10x10.jpg"></span></a>| <a href="https://www.listbox.com/member/?member_id=22720195&id_secret=22720195-8fdd4308" title=""><span style='color:#669933;text-decoration:none'>Modify</span></a> Your Subscription | <a href="https://www.listbox.com/unsubscribe/?member_id=22720195&id_secret=22720195-97c5b007&post_id=20140304063603:27F10D06-A391-11E3-A0FB-DD0E0CE2CF84" title=""><span style='color:#669933;text-decoration:none'>Unsubscribe Now</span></a> </span><o:p></o:p></p></td><td valign=top style='padding:0in 0in 0in 0in'><p class=MsoNormal align=right style='text-align:right'><a href="http://www.listbox.com"><span style='text-decoration:none'><img border=0 id="_x0000_i1026" src="https://www.listbox.com/images/listbox-logo-small.png"></span></a><o:p></o:p></p></td></tr></table><p class=MsoNormal><o:p> </o:p></p></div></div></body></html>
