+<h1>Wi-Fi Direct®</h1>
-<p>Wi-Fi Direct™ (synonym for Wi-Fi P2P (Peer-to-Peer)) is a technology that allows you to find nearby Wi-Fi Direct™ devices and form a Wi-Fi Direct™ group to communicate over a peer-to-peer link without wireless access points (base stations) in the infrastructure mode.</p>
+<p>Wi-Fi Direct® (synonym for Wi-Fi P2P (Peer-to-Peer)) is a technology that allows you to find nearby Wi-Fi Direct devices and form a Wi-Fi Direct group to communicate over a peer-to-peer link without wireless access points (base stations) in the infrastructure mode.</p>
<p>This feature is supported in mobile applications only.</p>
-<p>In a Wi-Fi Direct™ group, the group owner works as an access point in the Wi-Fi infrastructure mode and the other devices join the group as clients. A group can be created either by negotiation between 2 devices or in an autonomous mode by a single group owner device. In a negotiation-based group creation, 2 devices compete based on the group owner intent value and the higher intent device becomes a group owner, while the other device becomes a group client. In an autonomous group creation, a device becomes a group owner by itself without any group client.</p>

<h3>TDLS (Tunneled Direct Link Setup)</h3>
<p>A TDLS direct link is set up automatically between the devices, without intervention from the AP or the user. The connection with the AP is maintained.</p>
-<p>TDLS is not the same as, nor does it replace Wi-Fi Direct™. TDLS is used to optimize the traffic flow in a network, while Wi-Fi Direct™ is used to quickly connect devices to one another while on the go, even when a Wi-Fi network is unavailable.</p>
