I've been trying to search around for the effective wireless data throughput on the KW41z in different modes, ie. BLE, SMAC, Thread, Zigbee, with no luck.
Could you please check the AN12099 and the JN-AN-1035 ? As for BLE you will need to perform few calculations to get the data you want but you can always read the BLE spec for more details.
Also, please remember that the KW41Z ZigBee stack has not been released yet, but it will be available tentatively on the Q1 of 2018.
