Super strength signalling in marine and coastal regions
27 June, 2008
A particular window of time when mobile signals and radio waves are ‘super strength’ — allowing them to be clearer and travel greater distances — has been discovered by Salil Gunashekar as part of his doctoral studies at the University of Leicester’s Department of Engineering in England.
Frequency 'sweet spot' helps signals travel in tunnels
02 June, 2008
Underground tunnels, usually a difficult environment for radios, can have a frequency 'sweet spot' at which signals may travel several times further than at other frequencies, according to researchers at the National Institute of Standards and Technology (NIST), in the US.
Where we could be going with radio
