Satellite navigation and mobile telephone network could improve safety of trains

  • PDF
TechAndComputer (Apr. 23, 2010) — Engineer Jon Mikel Rubina puts forward alternative economical telematics for the current railway system, with applications enabling monitoring and control of elements that make up rail infrastructure.

The current situation of the safety of trains leaves room for improvement. The technology used has high financial costs, both in its implementation and in maintenance, and it is necessary to reach a compromise...

Bio-inspired computer networks self-organise and learn

  • PDF
TechAndComputer (Apr. 13, 2010) — Powerful computers made up of physically separate modules, self-organising networks, and computing inspired by biological systems are three hot research topics coming together in one European project.

European researchers have developed an innovative computing platform. At the heart of the system are many small modules, each made from chips with an inbuilt ability to learn. A self-configuring wireless network connects the modules, allowing them...

Wireless health care for diabetes

  • PDF
TechAndComputer (Apr. 1, 2010) — Online communities could easily be used to offer people with chronic illnesses, such as diabetes , wireless healthcare services via mobile phones and the internet. The approach, outlined in the International Journal of Networking and Virtual Organisations, would reduce healthcare costs and empower many patients to manage their condition more effectively.

Providing optimal healthcare while keeping costs down is...

Piping wireless into the home

  • PDF
TechAndComputer (Apr. 6, 2010) — Besides carrying digital data, optical fibers can also transmit radio signals for wireless communication. So-called "radio-over-fiber" technology has been used to provide access to radio dead zones, but new research is looking into using this technology to broadcast wireless closer to home.

Radio over fiber (RoF) modulates an optical wavelength in the fiber with a radio signal. This solves the attenuation problem...

Future of broadband: Where data is broadcast using desk lamps

  • PDF
TechAndComputer (Mar. 10, 2010) — In the future, getting a broadband connection might be as simple as flipping on a light switch. In fact, according to a group of researchers from Germany, the light coming from the lamps in your home could one day encode a wireless broadband signal.

"The advantage is that you'd be using light that is already there," says Jelena Vučić of the Fraunhofer Institute for Telecommunications, Heinrich-Hertz-Institute in G...
