  Support for Wi-Fi Direct lets users connect directly to nearby peer
  devices over Wi-Fi, for more reliable, higher-speed communication. No
  internet connection or tethering is needed. Through third-party apps,
  users can connect to compatible devices to take advantage of new
  features such as instant sharing of files, photos, or other media;
  streaming video or audio from another device; or connecting to
  compatible printers or other devices.

Unfortunately, this is not ad-hoc mode -- it's "Wi-Fi direct", which is
a Wi-Fi Alliance specification unrelated to IEEE 802.11.

  Is this the same as Ad Hoc mode?
  No, this is not Ad-Hoc mode (also known as IBSS) but an extension to
  the ubiquitous infrastructure mode of operation that can operate
  without a dedicated access point. Ad Hoc, or IBSS, mode is a legacy
  protocol for Wi-Fi devices, and Wi-Fi Direct is a new innovation. With
  the technology underlying Wi-Fi Direct, a device can maintain
  a simultaneous connection to an infrastructure network – this isn’t
  possible with Ad Hoc.

  Is the specification underlying the Wi-Fi Direct certification program
  based on the IEEE 802.11s (Mesh) or 802.11z (Direct Link Setup)
  No. The specification underlying the Wi-Fi Direct certification
  program was developed within the Wi-Fi Alliance by member
  companies. It operates on 802.11 devices but is not linked to any
  specific IEEE 802.11 amendment.
