A UHF radio link, designed and built by Benbro in Sydney, has been tested at the large Candelaria copper mine in Chile and will now become a permanent fixture.
The R&SOSP is an open platform for fast and easy implementation of RF switch and control tasks. Different models and optional modules make the platform suitable for a wide range of applications. It can transition from simple RF switch functions to the complex RF wiring of EMC systems, for example.
A system capable of simultaneously measuring hundreds of RFID tags and rapidly testing new RFID tag prototypes has been designed by researchers.
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.
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.
This look at what could happen in the future with radio services is taken from a presentation by Chris Chapman, ACMA chairman, when he addressed nearly 300 delegates at the RadComms conference in Melbourne.
General packet radio service (GPRS) technology allows devices to communicate with one another without the need for extensive cabling. Weidmüller’s GPRS alarm module IE-GPRS-I/O monitors plant and installations, reporting deviations automatically or on request.
