Rf Link Budget

Calculates wireless link budget using transmit power, antenna gains, distance, frequency, obstacle losses, and receive sensitivity. The template computes free-space path loss, total path loss, received signal level, and link margin.

with-tool: The model is given an executable Python calculator script.

How this task is generated

One template produces many comparable benchmark tasks while keeping the scoring contract fixed.

  1. 01

    Template

    The reusable contract shown on this page.

  2. 02

    Scenario

    An archetype and site context are sampled.

  3. 03

    Difficulty tier

    Inputs may be hidden at harder tiers.

  4. 04

    Task prompt

    The model responds with the declared outputs.

Parameters

Inputs the model receives, and the outputs it is scored on.

Inputs

7 inputs

Always given

Included directly in every task prompt.

Scored outputs

4 outputs

Free space path loss db

free_space_path_loss_db

Free-space path loss

Scores if within ±3% of the reference value.

Total path loss db

total_path_loss_db

Total path loss including obstacles

Scores if within ±3% of the reference value.

Received signal level dbm

received_signal_level_dbm

Received signal level

Scores if within ±3% of the reference value.

Link margin db

link_margin_db

Margin above required receive sensitivity

Scores if within ±3% of the reference value.

Difficulty

Each template is sampled at three tiers. Harder tiers may hide inputs, forcing the model to infer them from the scenario description.

easy

All inputs given

Short wireless link with all losses visible

medium

All inputs given

Short or long wireless link

hard

Some inputs hidden

Obstacle loss hidden in path context

Hidden inputs

  • Obstacle losses dbobstacle_losses_db
