January 2015 doc.: IEEE 802.15-15-0052-01-003d Background Several contiguous bands were discussed. [15-14-0613- 01-003d] The frequency range of 252-275GHz which are already allocated to mobile services were also discussed. [15- 15-0038-00-003d] In section 10 of TRD [15-14-0309-03-003d], the operational frequency bands are categorized into three bands, 60GHz, THz frequency band and free space optics. This contribution is to provide the candidate frequency bands for TG3d devices operating at THz frequency band. Submission Slide 2 Akifumi Kasamatsu, NICT
January 2015 doc.: IEEE 802.15-15-0052-01-003d Frequency Allocation below 275 GHz in Radio Regulation Allocation to services 250-252 GHz EARTH EXPLORATION-SATELLITE (passive) RADIO ASTRONOMY SPACE RESEARCH (passive) 5.340 5.563A 252-265 GHz FIXED MOBILE MOBILE-SATELLITE (Earth-to-space) RADIO ASTRONOMY RADIONAVIGATION RADIONAVIGATION-SATELLITE 5.149 5.554 265-275 GHz FIXED FIXED-SATELLITE (Earth-to-space) MOBILE RADIO ASTRONOMY Submission Slide 3 Akifumi Kasamatsu, NICT
January 2015 doc.: IEEE 802.15-15-0052-01-003d Available contiguous bandwidth in the frequency range from 100 GHz to 1000 GHz Submission Slide 4 Akifumi Kasamatsu, NICT
January 2015 doc.: IEEE 802.15-15-0052-01-003d Suitable frequency range and contiguous bandwidth Loss (dB/km) Frequency range (GHz) (1) 200-320* (2) 275-320 (3) 335-360 (4) 275-370 (5) 380-445 (6) 455-525 (7) 625-725 (8) 780-910 Contiguous bandwidth (GHz) 120 45 25 95 65 70 100 130 < 10 < 10 < 10 < 100 < 100 < 100 < 100 < 100 * It is difficult to have contiguous bands below 252 GHz because there are many bands not allocated for mobile services.

January 2015 doc.: IEEE 802.15-15-0052-01-003d Proposal to section 10 of TRD Not to identify the frequency band below 252 GHz for TG3d devices operating at THz frequency band. Identify the frequency band of 252-275 GHz for TG3d devices operating at THz frequency band. Further identify the frequency band of 275-320* GHz for TG3d devices operating at THz frequency band. * The frequency of 320 GHz will be further studied by referencing Recommendation ITU-R P.676-9, Attenuation by atmospheric gases . New frequency identification for TG3d devices Already allocated in RR 252GHz 275GHz 320GHz Submission Slide 6 Akifumi Kasamatsu, NICT
