What is the latest and best technology in your opinion?

Cloak and Dagger is an excellent platform for usage, and maybe even a potential brand name for this technology, which at its current stage employs hundreds of thousands of mirrored holographic discs to blend into an environment.
The potential for operatives, snipers and entry teams to avoid detection by sight makes it almost an unfair fight.
Law enforcement by fear alone? It’s a distinct possibility that simply knowing law enforcement can act counter to a criminal without their knowledge could decrease criminal activity at even the highest threat levels.
Currently only in its infancy, metamaterial cloaking is one of the more widely desired, and closely watched, technologies especially in the law enforcement space, as it has the opportunity to have the single biggest impact on human personnel and law enforcement procedure of any other conceived technology.
Future designs will likely include a combination of shape changing liquids/materials and highly faceted reflective discs which can also absorb color and light to further disguise the user in a more natural way.
and within the decade it may provide an amazing supplement to law enforcement agencies in the fight against terror, and all manner of other criminal activity.

Wireless link could match fibre data rates Researchers from the Fraunhofer Institute for Applied Solid State Physics and the Karlsruhe Institute for Technology have transmitted data wirelessly at 40Gbit/s over a distance of 1km using a carrier frequency of 240GHz.
The demonstration is said to set a new world record and match the capacity of optical fibre transmission.
This, the researchers suggest, may allow such radio links to supplement the broadband network in rural areas.
The transmitter and receiver chip, which measures 4 x 1.5mm, features high carrier mobility (HEMT)transistors.
This, says the team, makes it possible to use frequencies between 200 and 280GHz using active transmitters and receivers in the form of compact integrated circuits.
