IEEE Std 802.15.4x-2019 pdf free download – IEEE Standard for Low-Rate Wireless Networks Amendment 7: Defining Enhancements to the Smart Utility Network (SUN) Physical Layers (PHYs) Supporting up to 2.4 Mb/s Data Rates.
7. MAC frame formats
7.4 lEs
7.4.4 Nested IE
7.4.4.10 SUN Device Capabilities IE
Change the 151h paragraph in 7.4.4.10 as indicated:
The PHY Modes Supported field is a bitmap indicating which PHY modes are supported for the PHY Type. The PHY modes for each possible PHY Type are defined in Table 7-21, Table 7-22, Table 7-22a,Table 7-23, Table 7-24, Table 7-25, and Table 7-26. A bit set to one in bit bn of the PHY Mode ID bitmap indicates that the PHY Mode with ID n in the table of PHY Modes corresponding to the PHY Type is supported; otherwise, it is not supported.
Insert the fllowing new paragraph and Table 7-22a after Table 7-22 in 7.4.4.10:
The PSK-C PHY mode encodings are defined in Table 7-22a.
10. General PHY requirements
10.1 General requirements and definitions
10.1.2 Channel assignments
10.1.2.8 Channel numbering for SUN and TVWS PHYs
20. SUN FSK PHY
20.1 Introduction
Change the second paragraph of 20.1 as indicated:
For the SUN FSK PHY, the symbol period used for MAC and PHY timing parameters, shown in Table 20-1, shall be the symbol period of operating mode #1 (specified in Table 20-6 and Table 20-7) and operating mode #la (specified in Table 20-7a).
20.3 Modulation and coding for SUN FSK
Insert the following new paragraph and Table 20-7a after Table 20-7 in 20.3:
Frequency bands 470 MHz, 780 MHz, 863 MHz, 866 MHz, 867 MHz, 870 MHz, 915 MHz, 915 MHz-a,915 MHz-b, 915 MHz-c, 915 MHzd, 915 MHze, 917 MHz, 919 MHz, 920 MHz, 920 MHz-a, and 920 MHz-b may additionally support operating modes #1a and #1b as specified in Table 20-7a.IEEE Std 802.15.4x pdf download.
