Common WiFi can be used to scan for explosives and chemicals say researchers.

Researchers at Rutgers University have created techniques using WiFi broadcast  and receivers to image the interiors of baggage and backpacks.

The researchers' suspicious object detection system is easy to set up, reduces security screening costs and avoids invading privacy such as when screeners open and inspect bags, backpacks and luggage. Traditional screening typically requires high staffing levels and costly specialized equipment.

"This could have a great impact in protecting the public from dangerous objects," said Yingying (Jennifer) Chen, study co-author and a professor in the Department of Electrical and Computer Engineering in Rutgers-New Brunswick's School of Engineering.

Pretty interesting. I wonder if the folks at LMG would want to try to build their own WiFi imager.

I like that.

Guess who is going to get a large cheque from a three lettered company...

 

But can it detect objects like the Crysis nanosuit?

I can now think of a way to bypass this 

 

But if it can improve existing metal detectors, then why not.

Not fair comparison. He is offcourse the gooodest boy

[bcredeur97]

if they are using 2.4 GHz then airport wifi just literally got worse. yet more interference lol

I'd hope they are using 60 GHz or something if it's just for screening.

im all for it if it means better airport wifi

"Sir may we search your bag using this brand new wifi scanning technology using the power of the internet"

 

I dunno... What if my stuff gets infected with memes?

 

"How about we let this dog sniff your backpack"

 

DEAL
