CVMóvel, in partnership with Ericsson (NASDAQ: ERIC) and Portugal Telecom (PT) Foundation, is taking information and communication technologies (ICT) to students in Cape Verde schools. Through Connect To Learn, the global education initiative founded by the Earth Institute, Ericsson and Millennium Promise, which leverages ICT for a 21st century education in developing countries, three Cape Verde schools will have access to modern learning tools and educational resources.
Ericsson (NASDAQ: ERIC) e Intelsat SA (NYSE: I), el proveedor líder mundial de servicios por satélite, junto con los socios de BT Group plc (NYSE: BT), Sony (NYSE:SNY) y Newtec demostrarán en el Centro de Convenciones de Las Vegas, en el NAB Show 2014, la siguiente iteración de una verdadera 4K Ultra Televisión de Alta Definición (4K UHDTV) extremo a extremo.
Human exposure to the radio frequency electromagnetic fields (EMF) emitted by radio base stations (RBS) is proportional to the transmitted power. Thus, knowledge of actual power levels is key for a correct estimate of the actual EMF exposure. In this study, downlink output power distributions for RBSs in a 4G LTE mobile communication network have been determined. By extracting data using the operations support system (OSS) of the network, statistics were obtained based on 24 hours measurements for more than 5000 RBSs. The network measurement approach was verified with in-situ power density measurements. It was found that the actual output power levels are significantly below the theoretical maximum. For high-traffic periods, the 90th percentile transmitted power was found to be about 12% of the theoretical maximum.
