Dear Sirs,
We are evaluating nRF52840 now, How far is the maximum range it can reach while keeping the data rate at 2Mbps if we use two nRF52840 for point-to-point communication?
Thanks.
Steven

That depends a lot on what kind of an environment you are in. As this link explains (see answer 4), in normal office testing scenarios with short range & moderate to high WiFi interference, you can expect results of around 1100-1360 kbps. My guess is short range refers to the range shown in the high throughput demo Youtube video, although I would test this with two 52832 DKs or 52840 PDKs to verify the range more accurately (demo FW available here). If you want to try the demo out with an nrf52 DK or nrf52840 PDK & a Samsung S8, you can take a look at the github code.

Yes, it depends on the environment, we want to know two results:
1. How many meters it can reach in outdoor environment while keeping the data rate at 2Mbps ?
2. In normal office with moderate to high WiFi interference, how many meters it can reach while keeping the data rate at 2Mbps? Maybe it is not very accurate, but it is helpful.
I am unsure about an outdoor environment, but in a normal office with moderate to high WiFi interference, you should be able to get up to a couple of meters with a high throughput of around 1.2-1.3 Mbps. Again, to double check this, I would test it yourself to see if this is satisfactory.
There is also a great test that Gary from Android Authority did, which could be interesting to read. He got a throughput of 1.215 Mbps at a distance of 5m with one wall in between his two nrf52840 dev kits. You can assume a direct line of sight test would lead to greater range.
