Former EMC Society President Bob Hofmann on the Mend

 

Long time IEEE EMC Society member and past president Bob Hofmann is currently recuperating from a fall that occurred as he arrived home from a VCCI-related trip to Japan. Apparently, he sustained a fall and some head injuries as he was dropped off at his home. This past weekend, he underwent surgery to correct bleeding and remains hospitalized. The very good news is that the … [Read more...]

EU Member States Free Up Spectrum for New Mobile Services

 

On Monday, July 27 the Council of Ministers of the European Union agreed to open up a portion of the spectrum for the new generation of mobile devices. This approval was the last step required in a process of spectrum reform that already had the backing of the European Parliament and Commission.  In October of 2009, the 900-MHz band, which had been limited to use by traditional … [Read more...]
