Multimedia group communication services in mobile networks as a replacement for traditional trunked radio communication have attracted a lot of attention recently. This paper presents results from a newly developed simulation model to study the transfer of multimedia streams in group communication systems within different setups. As the real time ability of such a system has been identified as the...
Solar Systems has more than 10 years experience with grid-connected CPV systems using large reflective optics. Over the last 7 years, Solar Systems has deployed 47 dish units, of which 23 are with multijunction solar cells, in five different commercial CPV power plants and two testing facilities, for a total installed capacity of 1.5MWp. Recently, Solar Systems has designed and built a 140kWp Heliostat...
Multi-junction III–V solar cells have been in operation for the last two years in several 500X dish concentrator PV systems using reflective optics. The performance monitoring of these CPV systems on a 15-second basis has accumulated a very large amount of data and allowed for analysis of the influence of atmospheric parameters to the system efficiency. Dense array modules are assembled into large...
