7. IEEE 802-15-12-0052-00 Submission Scope This amendment specifies a physical layer (PHY) for IEEE 802.15.4, and medium access control (MAC) changes needed to support this PHY, for use in equipment intended to meet the United States (US) Positive Train Control regulatory requirements and similar regulatory requirements in other parts of the world. –Enables operation in licensed or license-free radio frequency bands below 6 GHz –Accommodates transmit power levels greater than the 1 W typical of Part 15 devices –Meets performance requirements at speeds up to 600 km/h –Supports radio ranges on the order of 70 km –Allows operation in contiguous or non-contiguous channel bandwidths as narrow as 5 kHz –Supports data rates up to 1 Mbps with flexible and robust quality of service –Provides modulation methods and spectral characteristics consistent with local regulatory requirements –Accommodates rapidly changing network membership., Slide 7
