RF & Wireless — question 8 of 10
Write a real answer. It is graded against the question's rubric, and the mastery movement is computed by the same engine the product uses. Scoring here is deterministic rather than model-written, so this page costs nothing to run and nothing is saved. In a track built from your own posting, the same rubric is graded by the model, which is what produces feedback about your reasoning rather than about coverage.
Tests whether the candidate can connect a logarithmic propagation model to a practical design decision.
A teammate wants to double the range of a wireless device and proposes simply increasing transmit power by 6 dB, reasoning that this should roughly double the range. Using the free-space path loss model, derive whether that intuition holds, and then explain why the actual range increase you'd measure in a real office deployment is often smaller than what the free-space math predicts.
This one resolves to a number. Give the value in the field below and your reasoning in the box — the number is checked exactly, by arithmetic.
