Final answer:
MBSS (Mesh Basic Service Set) is the 802.11 service set defined specifically for directional multi-gigabit (DMG) radios.
Step-by-step explanation:
The 802.11 service set that is defined specifically for directional multi-gigabit (DMG) radios is MBSS (Mesh Basic Service Set).
MBSS enables high-speed and long-range wireless communication among multiple DMG radios within a mesh network. It allows these radios to form multiple connections and transmit data simultaneously, improving overall network performance.
For example, MBSS can be used in large outdoor events or industrial environments where fast and reliable wireless connectivity is required across long distances.
