Concurrent Mode Radio Configuration#
Set Up Wi-SUN Concurrent Mode#
The concurrent mode configurations available are as shown below:
Regulatory Domain | Concurrent Base PHY | Concurrent Alternate PHY |
|---|---|---|
NA | FSK_50kbps_1b FAN1.1 Profile | OFDM option 1 FAN1.1 Profile |
JP | FSK_100kbps_2b ECHONET Profile | OFDM option 3 FAN1.1 Profile |
EU | FSK_50kbps_1a FAN1.1 Profile | OFDM option 4 FAN1.1 Profile |
Note: Depending on customer requests, other concurrent modes could be added in the future.
Concurrent Mode Configuration using the Simplicity Studio Radio Configurator#
With the last SiSDK, the Radio Configurator GUI allows you to select a concurrent PHY based on the previous table when selecting a radio profile Wi-SUN FAN 1.1 Profile in Protocol Configuration as shown below for the NA regulatory domain:
In the Channel Group, the base FSK PHY through the Wi-SUN PHY Operating Mode ID could be selected. Then selecting the Customized option, it could be possible depending on the FSK base PHY to select an alternate OFDM PHY for concurrent mode detection.
For example, the Wi-SUN FAN 1.1 with NA regulatory domain, the FSK 1b with 50kbps could be a base PHY providing Concurrent OFDM Option selection set by default to NONE as shown below:
In the previous snapshot with Concurrent OFDM Option set to NONE, it is an FSK mode 1b providing 50kbps with PHY Operating Mode ID=2. In the Concurrent OFDM Option list, the OFDM option can be selected to get a concurrent PHY with FSK plus OFDM as shown below:
The Alternate Base Channel Frequency, the Alternate Channel Spacing, and the Alternate Number of Channels are provided by default. These fields values are compliant as specified by the ChanPlanID in Wi-SUN PHY Technical Profile Specification 2V00. It is possible to modify these values nevertheless note the FSK channel plan should be compatible with the OFDM channel plan as described in section 1.
Notes:
For Regulatory domain JP, the PHY FSK_100kbps_2b uses the ECHONET Profile in place of FAN1.1 Profile with a preamble length of 15 bytes and an FCS length with 2 bytes CRC.
For Regulatory domain EU, a channel mask applies and forbids the use of some available channels in the middle and at the end of the RF band. The channel masking in the middle of the RF band is taken into account thanks to a RAIL callback provided by the stack (see RAIL_lib API Usage for Mode Switch PPDU).
