What is Wi-Fi Direct and how does it work?
Wi-Fi Direct is a technology that allows devices to connect to each other without the need for a wireless access point or router. It enables devices to communicate with each other directly, using a peer-to-peer connection. This technology is commonly used for file transfer, printing, and other applications that require device-to-device communication. Wi-Fi Direct uses the same Wi-Fi technology as traditional Wi-Fi networks, but it operates on a different frequency band and uses a different protocol to establish connections.
When a device is connected to a Wi-Fi Direct network, it becomes a “group owner” or a “client.” The group owner is the device that initiates the connection and sets up the network, while the client is the device that joins the network. Wi-Fi Direct connections are typically faster and more reliable than traditional Wi-Fi connections, as they don’t require the data to be routed through a central access point.
What are the benefits of having Wi-Fi Direct on?
