  1. Spurious and transmission power Regulations in Japanese 4.9-5.0/5.03-5.091GHz band Kazuhiro Okanoue, NEC Yasuhiko Inoue, NTT K. OKANOUE, NEC Y. INOUE, NTT

  2. Equipment authorization patterns • Licensed base station • Licensed/Unlicensed terminal • Two spurious rules for anti-interference areas or not • Spurious rule 1 for areas including limited interference areas, e.g. Tokyo(?) • Spurious rule 2 for areas other than limited interference areas • Licensed base station for spurious rule 1 • Licensed base station for spurious rule 2 • Licensed terminals for spurious rule 1 • Licensed terminals for spurious rule 2 • Unlicensed terminal K. OKANOUE, NEC Y. INOUE, NTT

  3. Possible Communication patterns limited interference areas Other than limited interference areas Licensed Basestation for other than limited interference areas Licensed Basestation for limited interference areas Licensed Terminal for other than limited interference areas High power High power low power low power Licensed Terminal for anti-interference areas Unlicensed Terminal K. OKANOUE, NEC Y. INOUE, NTT

  4. Spurious rules for 4.9-5.0GHz • 4870MHz > f: EIRP less than or equal to 2.0mW/MHz • 4870MHz  f < 4880MHz and 5020MHz < f 5270MHz:EIRP less than or equal to 2.5mW/MHz • 5270MHz < f  5342MHz: EIRP less than or equal to 0.2mW/MHz • 5342MHz < f: less than or equal to 1.0mW/MHz • 4840MHz10MHz, 4860MHz10MHz:rule 1: less than or equal to 0.2mW/MHz rule 2: less than or equal to 2mW/MHz For unlicensed terminals, rule 1 is always applied For Licensed Equipment K. OKANOUE, NEC Y. INOUE, NTT

  5. Spurious rules for 5.03-5.091GHz • 4990MHz > f: EIRP less than or equal to 2.0mW/MHz • 4990MHz  f < 5000MHz and 5120MHz < f 5270MHz:EIRP less than or equal to 2.5mW/MHz • 5270MHz < f  5342MHz: EIRP less than or equal to 0.2mW/MHz • 5342MHz < f: EIRP less than or equal to 1.0mW/MHz • 4960MHz10MHz, 4980MHz10MHz:rule 1: EIRP less than or equal to 0.2mW/MHz rule 2: EIRP less than or equal to 2mW/MHz For unlicensed terminals, rule 1 is always applied For Licensed Equipment K. OKANOUE, NEC Y. INOUE, NTT

  6. Allowable Modulation • Class 1 • OFDM: more than 1 sub-carrier in 1MHz band • Direct Sequence: 5 < spreading bandwidth/transmission rate • Class 2 • Amplitude, Phase, Frequency and Pulse modulations and their combination K. OKANOUE, NEC Y. INOUE, NTT

  7. Transmission Power Regulations • Licensed equipment (both basestation and terminal) • EIRP: less than or equal to 250mW and 50mW/MHz • The same EIRP for class 1 and 2 modulations • Unlicensed terminal • terminals using class 1 modulations • EIRP: less than or equal to 10mW/MHz • terminals using class 2 modulations • EIRP: less than or equal to 10mW K. OKANOUE, NEC Y. INOUE, NTT
