NIST Shows New Device Could Improve Fiber-Optic Quantum Data Transmission
08/08/2012 - 10:48

Tests performed at the National Institute of Standards and Technology (NIST) show that a new method for splitting photon beams could overcome a fundamental physical hurdle in transmitting electronic data. These results could lead to commercial systems that can help safeguard the transfer of sensitive information.

Internet research to level the playing field
08/01/2012 - 07:25

Short delays on the Internet can have serious consequences for share-traders or players of online computer games. Norwegian ICT researchers intend to do something about it. The Internet as we know it today has been optimised to transmit large amounts of data or “greedy streams” - the type of transmission involved in downloading large files or watching online TV.

Phase-sensitive optical data transmission: a new frontier
04/30/2012 - 09:40

Fibre-optic cables are becoming the backbone of the Internet, from the main trunk lines between cities, countries and continents to the network of cables running from telephone central offices to individual homes and mobile phone base stations. A pioneering approach to data transmission, supported by EU funding, promises to increase the capacity, range and efficiency of fibre-optic networks.

Multi-hop wireless networks for efficient data transmission
04/19/2012 - 08:50

Data transmission by networks have limits in the amount of data they can transmit. North Carolina State University researchers developed an efficient data transmission approach over multi-hop wireless networks. This approach can increase the efficiency by 20 to 80 percent.
