According to FCC rules, what is the maximum output to the intentional radiator (IR) for frequency-hopping spread spectrum with a 5 MHz bandwidth?

• A. 250 milliwatts (mW)
• B. 100 milliwatts (mW)
• C. 125 milliwatts (mW)
• D. 75 milliwatts (mW)

Answer: (C)

The correct answer regarding the maximum output for intentional radiators (IR) using frequency-hopping spread spectrum with a bandwidth of 5 MHz is 125 milliwatts (mW). This specification aligns with the rules set forth by the Federal Communications Commission (FCC) for devices operating under certain conditions. Specific regulations dictate that frequency-hopping systems must adhere to a maximum power limit to minimize interference and ensure efficient spectrum utilization. For systems utilizing a bandwidth of less than or equal to 5 MHz, the 125 mW output limit is established to facilitate compliance with the requirement that limits emissions and restricts the potential for disruption in shared frequency bands. In understanding this, it's essential to recognize that limitations on power output for different technologies exist to balance the operational capabilities of devices while safeguarding the integrity of communication channels and preventing undue interference with other electronic systems. Therefore, a frequency-hopping system operating at 5 MHz is rightly constrained to a maximum output of 125 mW as outlined in the FCC rules.
