Television‚ Inc.‚ 392 U. S. 390‚ the Court determined that a CATV provider was more like a viewer than a broadcaster‚ because its system “no more than enhances the viewer’s capacity to receive the broadcaster’s sig¬nals by providing a well-located antenna with an efficient connec¬tion to the viewer’s television set.” Therefore‚ the Supreme Court held that a CATV provider does not violate the exclusive right of the copyright holder and hence did not perform publicly. The Court reached the same determination

Results have shown that attachment of RF shield on mobile phone not only reduces SAR in head model but also the radiated power. Moreover‚ the RF shielding does not degrade the antenna performance. However there is slight variation in return losses when compared with RF shielding. So the RF shielding gives an option for compliance testing of mobile phones at the design stage. Another simulations show that a combined use of textiles
