  • Ecc Report 157 the Impact of Spurious Emissions Of
    ECC REPORT 157 Electronic Communications Committee (ECC) within the European Conference of Postal and Telecommunications Administrations (CEPT) ECC REPORT 157 THE IMPACT OF SPURIOUS EMISSIONS OF RADARS AT 2.8, 5.6 AND 9.0 GHz ON OTHER RADIOCOMMUNICATION SERVICES/SYSTEMS Cardiff, January 2011 ECC REPORT 157 Page 2 0 EXECUTIVE SUMMARY This ECC Report presents detailed analysis of the impact of fixed radiodetermination systems on other services/systems (i.e. Fixed service (P-P application), Mobile service (RLAN in 5 GHz band) and Radioastronomy service) operating in adjacent or different bands. This analysis was done on a theoretical approach, but results of some measurements of existing filtering solutions were also considered. A number of cases have been considered of major importance for defining levels of unwanted emissions in the spurious domain giving confidence of reasonably low occurrence probability of interference. Particular attention has been given to meteorological radars, which represent the majority of fixed installations presently subject to the 100 dBPEP attenuation required in ERC/REC 74-01. Further consideration was given to the levels in ERC/REC 74-01. In relation to FS, the Report considered: the impact of spurious emission, the very high power of the primary radars under consideration confirm the common assumption that, whichever would be the spurious limit in dBc, main-beam to main-beam coupling between radars and FS stations is not possible because in all cases the protection distance is in the order of several tens of km (in most cases lies beyond the horizon). Therefore, it is assumed that information about the FS and radar locations are known to administrations licensing their use; the impact of typical C band meteo radars on the variation of the potentially blocked azimuth angles for FS stations in the 6-8 GHz band was considered as more representative case.

Energy should be useful in specific applications, to generate a certain voltage level and make capable of delivering a recommended Power to the load. So, the main challenge for energy harvesting is to obtain a significant amount of power efficiently from the environment.
