doc.: IEEE /042 Submission January 2001 Mika Kasslin, NokiaSlide 2 Purpose Introduction to –DFS and TPC requirements in ERC/DEC/(99)23 –EU directive, ETSI guide and Harmonized EN

doc.: IEEE /042 Submission January 2001 Mika Kasslin, NokiaSlide 3 The ERC requirements: DFS Designated bands – MHz for indoor use – MHz for indoor and outdoor use DFS process required –to detect interference from other systems and avoid co- channel operation with them, notably radar systems –to provide a uniform spread loading across a minimum of 330 MHz, or 255 MHz in the case of equipment used only in the band MHz

doc.: IEEE /042 Submission January 2001 Mika Kasslin, NokiaSlide 4 The ERC requirements: TPC Designated bands – MHz for indoor use, mean EIRP limited to 200 mW – MHz for indoor and outdoor use, mean EIRP limited to 1 W TPC process required –both in up- and downlink to reduce the interference effect caused by RLANs under the coverage area of a satellite –to ensure a mitigation factor of at least 3 dB on the average output power

doc.: IEEE /042 Submission January 2001 Mika Kasslin, NokiaSlide 7 Harmonized Standard = Article 3.2

doc.: IEEE /042 Submission January 2001 Mika Kasslin, NokiaSlide 8 Harmonized EN Requirements: –Carrier frequencies and channelization –RF output power –Transmitter unwanted emissions outside the band within the band –Receiver spurious emissions –DFS –TPC
