May 2001 doc. : IEEE 802. 15 -01/255 r 0 FCC NPRM 01 -158 • Paragraph a. 1. iii Frequency hopping systems in the 2400 - 2483. 5 MHz band shall use at least 75 non-overlapping channels, except that as few as 15 non-overlapping channels may be used for systems that intelligently modify their hopsets in accordance with Section 15. 247(g). Hopsets modified in this manner must be re-determined at least once every 30 seconds. The average time of occupancy on any channel shall not be greater than 0. 4 seconds within a period of 0. 4 seconds multiplied by the number of hopping channels employed.

May 2001 doc. : IEEE 802. 15 -01/255 r 0 Vic’s Proposed Text 6 Regulatory Conformity and Spectrum Sharing Feasibility For a wireless project to be authorized, it shall address regulatory conformity and show spectrum sharing feasibility for its intended applications. At a minimum, the proposed project shall address: a) Conformance to existing regulations for proposed regulatory domains: ITU, regional, national, etc. b) Feasibility of coexistence with other IEEE 802 standards and projects, and other devices that share the spectrum c) Confidence that ongoing regulatory activity (e. g. FCC Notice Of Inquiry, Notice of Proposed Rule Making) will allow deployment of devices implementing the proposed standard Submission 10 Steve Shellhammer, Symbol Technologies

May 2001 doc. : IEEE 802. 15 -01/255 r 0 TG 2’s Version Regulatory Conformity and Coexistence with other Wireless IEEE 802 Standards For a wireless project to be authorized, the Project Authorization Request (PAR) shall require regulatory conformity and coexistence with other Wireless IEEE 802 Standards. At a minimum, the proposed project shall require: (a) Conformance to existing regulations for proposed regulatory domains (e. g. ITU, regional, national) or have indications that ongoing regulatory activity (e. g. FCC Notice Of Inquiry, Notice of Proposed Rule Making) will allow deployment of devices implementing the proposed standard. (b) Coexistence with other Wireless IEEE 802 standards and projects.
