  1. Project: IEEE P802.15 Working Group for Wireless Personal Area Networks (WPANs) Submission Title: [Possible PAR changes for 802.15.4g] Date Submitted: [12 May 2009] Source: [Kendall Smith,Mark Thompson] Company [Aclara RF] Address [23905 Mercantile Rd., Beachwood, OH 44122] Voice:[+1.216.896.8552] E-Mail:[mthompson@aclara.com, ksmith@aclara.com] Re: [IEEE 802.15.4g Working Group] Abstract: Discussion of a proposal to add provisions for Battery Operated Sensing Devices. Purpose: To allow for battery operation in 802.15.4g network Notice: This document has been prepared to assist the IEEE P802.15. It is offered as a basis for discussion and is not binding on the contributing individual(s) or organization(s). The material in this document is subject to change in form and content after further study. The contributor(s) reserve(s) the right to add, amend or withdraw material contained herein. Release: The contributor acknowledges and accepts that this contribution becomes the property of IEEE and may be made publicly available by P802.15. Kendall Smith, Mark Thompson, Aclara RF

  2. Possible PAR changes for 802.15.4g • Valid frequency bands • Data rate • Battery operation • Internet Protocol support • Support for legacy equipment Kendall Smith, Mark Thompson, Aclara RF

  3. Valid frequency bands Currently: “Operation in any of the regionally available license exempt frequency bands, such as 700MHz to 1GHz, and the 2.4 GHz band” Proposed: “Operation in any of the regionally available license exempt frequency bands or dedicated use bands” Kendall Smith, Mark Thompson, Aclara RF

  4. Data rate Currently: “Data rate of at least 40 Kbits per second, but not more than 1000 Kbits per second” Proposed: “Data rate of at least 40 Kbits per second” Or: Two new limits? Kendall Smith, Mark Thompson, Aclara RF

  5. Battery operation Currently: - nothing - Proposed: “Support low power operation to support battery powered devices that may require up to 20 years battery life” Kendall Smith, Mark Thompson, Aclara RF

  6. Internet Protocol support Currently: - nothing - Proposed: “Support Internet Protocol (IP) as efficiently as possible” Kendall Smith, Mark Thompson, Aclara RF

  7. Support for legacy devices Currently: - nothing - Proposed: “Provide support for legacy devices as feasible” Kendall Smith, Mark Thompson, Aclara RF

  8. Possible PAR changes for 802.15.4g Will this delay the progress of 4g? - Maybe, but let’s minimize the impact Will we incure the wrath of the EC? - Some say yes. Is that a valid reason? Can’t we just evolve the standard later? - Does that match the need? Is the benefit worth the trouble / risk? - That is the key issue! Kendall Smith, Mark Thompson, Aclara RF

  9. Scope:This Standard defines an amendment to IEEE 802.15.4. It addresses principally outdoor Low Data Rate Wireless Smart Metering Utility Network requirements. It defines an alternate PHY and only those MAC modifications needed to support its implementation. Specifically, the amendment supports all of the following: Operation in any of the regionally available license exempt such as 700 MHz to 1 GHz or the 2.4 GHz band. Data rate of at least 40 Kbits per second, but not more than 1000 Kbits per second Achieve the optimal energy efficient link margin given the environmental conditions encountered in Smart Metering deployments. Principally outdoor communications PHY frame sizes up to 1600 octets Simultaneous operation for at least 3 co-located orthogonal networks Connectivity to at least one thousand direct neighbors characteristic of dense urban deployment Provides mechanisms that enable coexistence with other systems in the same band(s) including IEEE 802.11, 802.15 and 802.16 systems.
