Month Year doc.: IEEE 802.11-yy/xxxxr0 January 2010 Abstract IEEE 802.11 currently doesn’t standardize usage of the 900 MHz ISM band. While the band is limited, it is attractive for outdoor usage. David Halasz, Aclara John Doe, Some Company

January 2010 900 MHz ISM Band and IEEE 802.11 Current IEEE 802.11 standard does not cover the 902-928 ISM band. This band does have an advantage over 2.4 GHz, 3.65 GHz and 5 GHz because of range per transmit power. Better free space propagation loss Better clutter propagation loss. i.e. trees, telephone poles Increase in battery life A disadvantage is the limited bandwidth. However sufficient for 5, 10 and 20 MHz OFDM Smaller channels also allows for bandwidth sharing David Halasz, Aclara

SmartGrid has a large outdoor component January 2010 SmartGrid has a large outdoor component Use IEEE 802.11! Select band and channel width to meet the usage needs. David Halasz, Aclara

Use existing IEEE 802.11 PHY for quick solutions January 2010 Use existing IEEE 802.11 PHY for quick solutions Solutions today with added down converter. Possible future solutions similar to dual mode .11a/.11g WLAN cards. David Halasz, Aclara

Standardization effort January 2010 Standardization effort Standardization effort should be similar to IEEE 802.11y. IEEE 802.11y PAR approved 3/16/2006 REVCOM Standards Board Approval 9/26/2008 Efforts within IEEE 802.11k, .11y and current .11m will make this effort easier provided not a new PHY.

PAR & 5 criteria Criteria from 802 Policy and procedures January 2010 Broad Market Potential Broad sets of applicability. Multiple vendors and numerous users. Balanced costs (LAN versus attached stations). Compatibility Distinct Identity Substantially different from other IEEE 802 standards. One unique solution per problem (not two solutions to a problem). Easy for the document reader to select the relevant specification. Technical Feasibility Demonstrated system feasibility. Proven technology, reasonable testing. Confidence in reliability. Coexistence of 802 wireless standards specifying devices for unlicensed operation Economic Feasibility Known cost factors, reliable data. Reasonable cost for performance. Consideration of installation costs. David Halasz, Aclara
