What is Wi-Fi Direct (WFD) Protocol?

In proximity extension, the devices running in the same application can establish direct connection between them.

It helps you to connect two devices without using a Router or Bluetooth.In addition, it is a single hop communication between the devices. Besides, It has the ability to connect devices of different manufacturers. It negotiates the link with a Wi-Fi Protected Setup system which assigns the devices with a limited wireless access point. And the pairing of the device can be done to establish the communication.

Basic Function of Wfd Service:

While using this service feature for communication between Wi-Fi devices, you don’t need to use an Access Point (AP). We know this kind of communication as Wi-Fi P2P (peer-to-peer). It works in two steps only: – Device and service discovery.

In the first step, you need to use the Device discovery. Hence, you need to take help from a device that helps to broadcast a probe request for MAC addresses. What it does is scans the devices that are available nearby. This phase is known as the Scanning phase. Devices that get the probe request give a response by sending a unicast message to the sender. It is known as the find phase.

The next step is known as Service discovery. In this case, the sender device usually sends a unicast service request to the receiver. After that, the sender device sends a unicast message in turn that contains service details. Next, these devices get connected so that they can form a P2P group. It works quite similarly to a Wireless network. This step consists of two phases that are as follows:- formation and operational phase.

The device which exhibits Access Point-like function will be the P2P group owner. It is also known as P2P GO. On the other hand, the remaining devices will become P2P clients. If you want to connect the group to an external network, then you must use the P2P GO device. The reason is that it is the only one that allows doing this.
