  1. Project: IEEE P802.15 Working Group for Wireless Personal Area Networks (WPANs) Submission Title: [Discussion about DSSS Channelization and Resolution for Comment #341 ] Date Submitted: [November 2012] Source:[Tuncer Baykas, Shuzo Kato] Company [Tohoku University] Address [Sendai, Japan] Abstract:[Discussion about DSSS Channelization] Purpose:[Providing Resolution for Comment #341] 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.

  2. Comment #341 and Current LECIM Channelization Comment #341: Add DSSS channelization to bands 922, 917, 920, 921. This will allow manufactures to support certain regulatory domains. LECIM PHY Channelization: FSK PHY bands: 169,433,470,780,863,915, 922,917,920,921 (915 subbands) DSSS PHY: 2450, 470, 780, 863, 915, Statement in 8.1.2.12 Channel numbering for LECIM PHYs: For all bands except the 2.4 GHz band, if the device supports the band, it shall support all channels within the band. Slide 2 Tuncer Baykas , Tohoku University

  3. Consequences of Adding Bands From the point of silicon manufacturers: No major change: If they produce a chip for 915 band, that chip will support bands 922, 917, 920, 921 automatically. From the point of the editor: Only change in the draft standard will be Table 66a rest of the standard does not need any change. From the point of device manufacturers: They can decide if the end device supports all 915 band channels or specific bands 922, 917, 920, 921 depending on the regulatory domain that they want their device to operate.
