change CC1310 Frequency band and data rate on ti-15.4 stack

hi all,

Can i change the ti-15.4 stack RF parameters with Freq band(480MHz) and data rate(long range mode 625bps)*2  and how to do it?

now,we need using the ti 15.4 stack to build our system,but it different with Wi SUN(data rate  and rf band)

at project config file(config.h *1) to set the different band mode(us or Europe).

ref IEEE 802.15.4g - Wi SUN Alliance doc , it can  Flexibility support additional data rates
 and Support for Global and Regional frequency  bands

*1: config.h setting

/*! PHY IDs - 915MHz US Frequency band operating mode # 1 */
#define APIMAC_STD_US_915_PHY_1 1
/*! 863MHz ETSI Frequency band operating mode #1 */
#define APIMAC_STD_ETSI_863_PHY_3 3

*2.

how to import the smart rf studio 7 rf parameters to our project

*3:

CC1310 128K/20K ,5x5

    (reposting answer from TC - undoing accidental deletion)
    It is not possible to change the data rate and RF settings in TI-15.4Stack. If you require custom phy setting (not complaint with 802.15.4g setting used by TI15.4-Stack) then you should use the Proprietor RF example, which allow you to export directly from SmartRf Studio. Please look at the available examples and how to use them here:

    Currently only two data rates are supported with TI 15.4-Stack - 50kbps and 5kbps. Frequency bands supported are 915MHz, 863Mhz and 433MHz.

    hi ,

    we have asked ti to change the RF frequency band to 485M. and channels mask.

    then ti give me a project files.(it seem only change mac_pilb.c)

    i have been test ,but the performance less than 915M .

    Can anyone give me Suggest for this? only change the mac_plib.c defined?
