Bands A & B update

1. Bands A & B update Andy Gowans Private Business Systems UnitUK Radiocommunications Agency Andy Gowans - UK RA

2. UK update IR 2006 SI 2003 No.74 ETSI EN 301 893 DFS parameters Effect on UK IR2006 Structure of the presentation Andy Gowans - UK RA

3. IR2006: Short Range, Broadband, Data Services (High performance RLAN) operating in the frequency range 5150 - 5725 MHz Completed EU notification October 2002. 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 Andy Gowans - UK RA

4. 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 IR2006 Interim ArrangementBand A (5150-5350MHz) VALID FOR 12 TO 18 MONTHS FOR NEW EQUIPMENT ! Andy Gowans - UK RA

5. IR2006 Full Arrangement • Bands A (5150-5350MHz) • PSD shall not exceed 10mW/MHz. • Max E.I.R.P 200mW • INDOOR ONLY • Band B (5470-5725MHz) • 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 http://www.radio.gov.uk/publication/interface/ Andy Gowans - UK RA

6. New Statutory Instrument New draft SI to allow both Licence Exempt use and provision of public networks put before parliament in January 2003. SI 2003 No.74 Became law on the 12th of February 2003. Allows the Licence Exempt use of Equipment that meets the requirements of IR 2006. Allows the provision of public service. see http://www.legislation.hmso.gov.uk/stat.htm Andy Gowans - UK RA

7. EN 301 893 going through two step approval process currently doing the final comment resolution before voting. Looking to resolve comments April meeting and submit for vote. ETSI Andy Gowans - UK RA

8. Table D.1: DFS requirement values Parameter Value Channel Availability Check Time 60 s Channel Move Time 10 s Channel Closing Transmission Time 220? ms DFS parameters from EN Annex D Andy Gowans - UK RA

9. Table D.2: Interference Threshold values Master Device Maximum Transmit Power Value >200 mW -64 dBm £200 mW -62 dBm DFS parameters from EN Annex D Andy Gowans - UK RA

10. Slave device threshold ? Example 1: Maximum Transmit Power Value >200 mW -64 dBm £200 mW N/A Example 2: Maximum Transmit Power Value >200 mW -62 dBm 121 - 200 mW -55 dBm £120 mW N/A Example 3: Maximum Transmit Power Value >500 mW -62 dBm 201 - 500 mW -59 dBm 101 - 200 mW-55 dBm 51 - 100 mW-52 dBm £50 mW N/A Andy Gowans - UK RA

11. Ad hoc networking threshold Maximum Transmit Power Value >200 mW -64 dBm 26 - 200 mW -62 dBm £25 mW N/A Radar detection is not mandated in 5150 - 5250 MHz. Andy Gowans - UK RA

12. 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. Andy Gowans - UK RA
