A link budget provides a detailed analysis of the power budget, accounting for the gains and losses at each stage of the transmission path and hence determines whether a communications link will perform successfully or not. Link budget guides engineers in designing communication systems where the transmitted power, antenna gains, receiver sensitivity, and other parameters are appropriately chosen for reliable communication. Link budget accounts for all gains and losses to provide a quantitative assessment of the system’s performance, helping engineers estimate the achievable data rates, coverage range, and signal quality. Link budgets also help ensure compliance with regulatory standards, such as maximum permissible transmit power levels, interference limits, and signal quality requirements.
