Unique RF shielding technology is nanotube-based

NaturalNano Inc, of Rochester, NY, USA, has exclusively licensed technology that allows for selectively turning on or off access to radio signals, such as those used by cellphones or wireless computer networking devices, in areas that otherwise are shielded from those signals.

NaturalNano licensed U.S. Patent No. #6,885,845 "Personal Communications Device Connectivity Arrangement" from AMBIT Corporation. This patent complements the Company's current research and development efforts in RF shielding. The license extends to all fixed, non-mobile applications of this technology.

Michael Riedlinger, President of NaturalNano, said, "Exclusive access to this patent for fixed installations allows NaturalNano to offer a RF shielding solution utilizing its pre-loaded natural halloysite nanotubes technology combined with the ability to selectively turn on and off the impact of such shielding. This in turn enables authorized users to log onto a private network in an area that is otherwise RF shielded. Depending on the specific user requirements, this technology provides the framework for a potential new revenue stream into a facility's networking solutions for prospective customers and visitors. This technology also allows the facility operator to potentially charge fees for wireless access within an otherwise RF shielded environment. In addition, many existing structures including concert and convention halls, movie theatres, and other buildings could benefit from enhanced control over outside RF radiation with a passive, cost-effective solution."

Robert J. Crowley, President and Co-founder of AMBIT Corporation, said "We are pleased to have licensed this important technology to NaturalNano to complement their recent innovations in RF shielding technologies. We believe that there is a strong market need for intelligent cellular and WIFI control in fixed locations such as school buildings, offices, and in military applications and NaturalNano is the right company to bring these technologies to the marketplace.

"Until now, there has not been a practical, profit generating cellular shielding system that can be turned on or off. Unlike illegal jamming, our system monitors and controls the flow of radio, cellular and WIFI signals into a building and has a built-in billing function, too. The license to NaturalNano includes AMBIT Corporation's technologies to direct and route revenue-generating information streams in a shielded environment."

The use of metalized halloysite nanotubes for RF shielding came about as a result of a NaturalNano research and development program. Experimental trials included creation of a spray coating embedded with copper-filled halloysite nanotubes. The resulting material demonstrated significant RF signal strength reduction capability.

NaturalNano's spray-on shielding formulation, when applied to the walls of a room, may provide a passive blocking agent for RF energy. Creating RF shielded environments has typically involved extensive use of conductive wiring and construction materials, a labour and capital intensive undertaking. NaturalNano believes that this new approach to creating a shielded environment, using a spray-on formulation, may provide an effective application solution on a much more cost-effective basis. This technology is particularly applicable to existing and non-mobile rooms because of the high costs associated with retrofitting an existing room to make it a passively RF shielded environment using current RF shielding techniques.
