   A network administrator is upgrading a wireless network to support IoT sensors that transmit small data packets periodically. The sensors are battery-powered and need to conserve energy. The admin is considering using 802.11ah (Wi-Fi HaLow) instead of standard Wi-Fi. What is the primary advantage of 802.11ah for this use case?

   • AIt uses the same 2.4 GHz band as standard Wi-Fi, ensuring compatibility.
   • BIt operates in sub-GHz bands, providing longer range and better penetration, which can reduce the number of access points needed.
   • CIt provides higher data rates than 802.11ax, enabling faster sensor data uploads.
   • DIt requires no authentication, simplifying sensor deployment.
