NRF52 indoor range

[Yegor]

For the first, impressed by your intoducing NRF52 chip.

Question: what`s NRF52 indoor range using onboard antenna and maximum output power (+4dBm)? Thanks.

While it's hard to give exact numbers on range as Dave said we can calculate how much improvement you would see from the nRF51. With an improved link budget of 5dB we get an increased range of about 70% in those cases where we can ignore losses.

What makes the calculation a lot harder is that on-the-air loss is a function where one of the main contributors are range. Additionally you have the loss through solid or semi-solid objects which can be very significant, think concrete vs. lead chamber. This is why you are very likely to get a cryptic answer.

You mention a 5dB improved link budget. However Tx (max) is still +4dB and the Rx (sensitivity): -96dB (from -93dB on nRF51). Isn't this only a 3dB improvement not 5dB
