Area 51's wireless tracking system
 

for any of you alien/area 51 buffs definately a good read.
amazing how they monitor that area so much and they deny every claim to have anything of that nature there i understand the aircrafts they test are topsecret and what not but is it necessary to have sensors plotted miles away from the base?

what are they hiding i want to see! lol

Even without aliens, the facility has its secrets, and last year while roaming the desert outside the Groom Lake base Clark stumbled upon one of them: an electronic device packed in a rugged case and buried in the dirt. Marked "US Government Property," the device turned out to be a wireless transmitter, connected by an underground cable to a sensor buried nearby next to one of the unpaved roads that vein the public land surrounding the base. Together, the units act as a surveillance system, warning someone - somewhere - whenever a vehicle drives down that stretch of road.

Similar devices had been spotted in the area in the early 90s, but they were crude and bulky, stashed in the bushes and easily spotted. They were later withdrawn. The new road sensors are more clandestine, given away only by a slender antenna poking up through the dirt. "They're very, very hard to find, because there's just this little wire, like a blade of grass," says Arnu.
Sniffing Out Surveillance

Arnu, a Las Vegas software engineer, has shared Clark's preoccupation with the Groom Lake base since 1999, when he made a trip to the area to see what all the fuss was about. "I thought, okay, I'll give it a try, see what's out there... A couple of days turned into a couple of weeks and before I knew it I started developing a website about Area 51," says Arnu.

So when Clark found the new generation of road sensor, Arnu drove out to help investigate further. The pair found that, at close range, they could use a handheld frequency counter to pick up the wireless signals given off by the devices as a car passes. Over the following month and half, Clark and Arnu engaged in a kind of geocaching game with the Men in Black, systematically sniffing out the road sensors with the frequency counter, exhuming them, and opening them up. They discovered that each device was coded with three-digit identifier that could be read off an internal dial, allowing Arnu to make a list that correlated each unit's ID number with its GPS coordinates, creating a virtual map of a portion of the surveillance network surrounding the Groom Lake facility. Some of the sensors were miles away from the lake.

While it was probably a top secret testing ground at one time i'd guess that they have created a smoke and mirrors effect by keeping people focused and guessing what's going on there while doing their "secret" projects elsewhere.

yea thats tru its a good way to go about it no one really knos for sure execpt the personell they have there, is it true that they have a base inside the rocky mountains? i heard it's invunerable to nuclear blasts and attacks of that nature..
