NJIT Docket # 14-017
RADIATE: RADio-over-fiber as AnTenna Extender
Inventors: Nirwan Ansari, Tao Han
Intellectual Property & Development status: US Patent Protection is pending. Patent Publication No. US-2016-0174241-A1
NJIT is currently seeking commercial partners for the further development and commercialization of this opportunity.
Technology Brief: Researchers at New Jersey Institute of Technology in the Department of Electrical and Computer Engineering have invented a cost effective and high quality communications solution for provisioning broadband Internet services in high-speed trains.
Providing broadband Internet services in high-speed trains is important for passengers. The current solutions to enable high-quality broadband Internet services in high-speed trains either have high capital expenditure for deploying network infrastructure or do not have high quality communication. Current solutions utilizes the cellular network as backhauls to avoid the expensive capital expenditure involved in providing broadband Internet services in high speed trains. However, the drawbacks of using cellular network are rapid channel variations and overly frequent handovers. The novel broadband communication solution for high speed trains named RADIATE (RADio-over-fIber as AnTenna Extender) overcomes rapid channel variations and overly frequent handovers, the major drawback of using cellular network, by deploying ‘moving cell’ concept utilizing the fiber links to form an antenna system on the roof of the train, which virtually extends the antenna of individual users.
