I want to get a good performance of SI4463 communication. The setting attached now reach to 300 meters. what can i change to get longer distance.? It shall be compatible with the setting in use.
If "It shall be compatible with the setting in use." means the PHY is fixed, you don't have too much to change in the radio settings. Enabling IQ calibration would probably improve image rejection. Anyway 300 meters sounds quite decent, depending on your HW. Did you measure sensitivity or any other performance data that does not meet the datasheet specification and makes you think the WDS generated config should be further optimized?
