Latest negotiations that pave the way for a coherent set of rules on new spectrum use are poised to help the EU achieve the much talked about Digital Agenda. The Commission has made a clear call to Member States to put in place procedures to promote coexistence between new and existing services. But the latest text of the new Radio Spectrum Policy Programme (RSPP) falls short … [Read more...]

Apple Blocks Cell Phone Radiation App
Apple has blocked an application for the iPhone that tells owners when radiation levels have inched up too high and provides advice on how to counter the potentially damaging effects of phone radiation. The company that invented the app says that its solution gives users the information and tools to avoid mobile phone radiation as much as possible. It works by "mapping" homes … [Read more...]
San Francisco Passes Cell Phone Radiation Law
The San Francisco Board of Supervisors has passed a new ordinance requiring cell phone retailers to display and distribute a state-produced fact sheet that explains radio frequency emissions from cell phones and how consumers can minimize their exposure.This ordinance amends the city's controversial Cell Phone Right to Know Act, a similar law passed last year that required cell … [Read more...]
EMC Business Bulletin – September, 2011 – Volume 13
Where is the EMI Shielding Market Growing? The market for EMC components has grown rapidly, according to one recent study, specifically the EMI shielding market. The study performed by BCC Research indicates that the EMI shielding market has grown from approximately $500 million in 2002 to $4.5 billion in 2011, and is forecasted to grow to $5.26 billion by 2016. Frankly, I … [Read more...]
Power Quality and EMC in Smart Grid
Magnus Olofsson, President, Elforsk – Swedish Electrical Utilities’ R & D Company, Stockholm, Sweden The Smart Grid is increasingly seen as a means to facilitate climate friendly renewable energy sources (renewables), and as a way to enable efficient use of electricity. For example, modern electrical networks can link wind- and solar power with electric cars. A consequence … [Read more...]
EMC Testing above 1 GHz: The Deadline Looms
When first mandated in the 1990s, the stated objective of the EU’s Directive governing EMC was, in broad terms, that commercial and domestic equipment, and certain industrial systems, should neither cause interference or be susceptible to interference. They should not emit radiated or conducted energy at RF frequencies and they should be immune to such emissions, within … [Read more...]
