Range/power: IEEE802.15.4 (thread) vs. Bluetooth 5

[Reto]

Dear experts,

Comparing:

• IEEE802.15.4, Thread protocol, 250kBit/sec,
• Bluetooth 5, Coded PHY (longest range), 125kBit/sec

Questions:

• Which technology has longer range?
• Which technology has better range/power ratio?
• What current consumption can I expect of nRF52840 when Rx/Tx 802.15.4 thread protocols?

Thanks!

I did some tests with Thread (IEEE 802.15.4, 2.4GHz): indoor range (1 concrete ceiling, or two concrete walls) is up to 20m. Then the connections stops being reliable. I did not test outdoor or line-of-sight tests (with nRF52840 Development Kit). So I would say this is in the range of what I had reached with Bluetooth 4.1.
