Final answer:
Wi-Fi Direct is the Wi-Fi Alliance technical specification equivalent to ad hoc mode, allowing direct device-to-device communication without a central access point.
Step-by-step explanation:
The technical specification of the Wi-Fi Alliance that is the same as ad hoc mode in a Wi-Fi network is known as Wi-Fi Direct. In ad hoc mode, devices communicate directly with each other without the need for a central access point or router. Wi-Fi Direct offers a similar functionality by allowing Wi-Fi devices to connect to each other directly for data sharing or communication purposes. It's designed to be easy to set up and use, providing a convenient way to connect devices without the need for an existing network infrastructure.
