  1. Kazu Takahashi, Panasonic 60 GHz band Japanese Regulatory Update Authors: • Date: 2015-May-xx

  2. Abstract • This contribution provides a latest status for the Japanese regulatory status which may affect on 802.11ay specifications. • Major changes are; • Antenna input power • Occupied bandwidth • New rule is under discussion. Now asking for public comment until May 22nd (17:00 JST).

  3. 60 GHz band Regulations

  4. Kazu Takahashi, Panasonic Antenna input power and antenna gain • Defined two categories • 1: Existing low emission power point to point system • 2: Higher emission power point to multi-point system • Existing system (no changes) • Antenna power is less than 10 mW • Antenna gain is less than 47 dBi • EIRP is not specified • New system (antenna power in excess of 10 mW) • Antenna power is 10 mW ~ 250 mW • Antenna gain should be greater than 10 dBi. • EIRP is less than 40 dBm

  5. Kazu Takahashi, Panasonic Occupied bandwidth/Unwanted emission • OBW • Not specified up to 9 GHz • Allowable value of unwanted emission intensity • Defined as absolute value referring 11ad spectrum mask Lower Band Ch#1 Ch#2 -9 dBm/MHz -17 dBr -26 dBm/MHz -22 dBr -30 dBm/MHz -30 dBr 54 55 56 57 58 59 60 61 0.94 2.7 1.2 -3.06 -0.94 3.06 -1.2 -2.7 58.32 GHz 60.48 GHz Upper Band Ch#4 Allowable value of unwanted emission intensity -9 dBm/MHz -17 dBr 11ad/WiGig Spectrum mask -26 dBm/MHz -22 dBr -30 dBm/MHz -30 dBr 62 63 64 65 66 67 68 69 0.94 2.7 1.2 -0.94 -3.06 3.06 -1.2 -2.7 64.8GHz

  6. Kazu Takahashi, Panasonic Technical Conditions Detail (Draft)

  7. Kazu Takahashi, Panasonic Measurement Method • Measurement method for new regulation is not defined yet, it will be defined after approved. • Possible method; • Single Antenna: Antenna Power can be calculated by measured EIRP, subtracting with antenna gain. • MIMO: Aggregating for each antenna power DUT Spectrum Analyzer/ Power Meter 3mdistance recommended EIRP Antenna power

  8. Kazu Takahashi, Panasonic Conclusion • Japanese new regulation will support long range usage and higher throughput using channel bonding • OFDM based channel bonding would be better to meet unwanted out of band emission.
