doc.: IEEE /015r0 Submission March 2003 Andy Gowans - UK RA IR2006: Short Range, Broadband, Data Services (High performance RLAN) operating in the frequency range MHz Completed EU notification October Includes interim arrangements to allow use of equipment with limited DFS capabilities ( i.e no radar detection) Devices in the mobile service associated with Mobile/Nomadic and Local Area Network applications) UK Interface requirement

doc.: IEEE /015r0 Submission March 2003 Andy Gowans - UK RA IR2006 Interim Arrangement Band A ( MHz) Reduce the power level: where no TPC nor full DFS can be implemented equipment shall only operate at a maximum power level of 60 mW. Where TPC is implemented equipment shall only operate at a maximum power level of 120 mW Limited DFS Equipment operating in this band must implement a random channel access mechanism capable of operating on all 8 carrier frequencies. INDOOR ONLY VALID FOR 12 TO 18 MONTHS FOR NEW EQUIPMENT !

doc.: IEEE /015r0 Submission March 2003 Andy Gowans - UK RA IR2006 Full Arrangement Bands A ( MHz) PSD shall not exceed 10mW/MHz. Max E.I.R.P 200mW INDOOR ONLY Band B ( MHz) PSD shall not exceed 50mW/MHz. Max E.I.R.P 1W Both Bands A & B DFS. Equipment operating in this band must implement a random channel access mechanism capable of operating on the all carrier frequencies within 330 MHz of the spectrum in bands A and B. Shall prevent co-channel operation in the presence of Radar signals. TPC shall be employed to ensure a mitigation factor of at least 3 dB on the average output power of the network. OFDM Mandatory see

doc.: IEEE /015r0 Submission March 2003 Andy Gowans - UK RA Conclusions May have to make alterations to IR2006 once DFS thresholds are completed. Changes will only make the requirements for DFS within Bands A & B less stringent from the present IR2006.
