Overview

Wi-Fi Direct, also known as P2P (Peer-to-Peer) is a communication protocol based on standard Wi-Fi technology. Its core feature is forming a 1:N star topology network structure (one GO connects multiple GCs) without requiring traditional routers or access points (APs).

Device Roles:

• Group Owner (GO) : Acts as a soft access point (Soft AP), responsible for group management and data routing.
• Group Client (GC) : A device connected to the GO, functioning similarly to a traditional Wi-Fi client.
• P2P Device: A device not yet joined to a group, in a discoverable or pending connection state.

Advantages

Simple Connection

Through the standard P2P protocol, devices can directly establish peer-to-peer connections, ensuring good compatibility.

High Bandwidth & Low Latency

Based on Wi-Fi PHY layer, significantly higher transmission rates than Bluetooth.

Enhanced Security

Supports WPA2/WPA3 enterprise encryption. Peer-to-peer transmission avoids cloud relay, mitigating privacy leakage risks.

Typical Applications

Mobile Phone as GO Controlling Smart Devices:

When a mobile phone acts as the Group Owner (GO), other devices (e.g., smart home terminals) serve as Group Clients (GCs). They directly form a local area network without routers. The GO device provides AP-like functionality, centrally managing intra-group connections and data relaying. This enables direct control of smart devices via the mobile phone (e.g., monitoring cameras or controlling appliances).

Smart Device as GO Supporting Multi-Terminal Tasks:

Mobile phones and PCs can simultaneously send tasks (e.g., document printing) to a printer.

Provisioning:

A mobile phone delivers the router’s SSID and password to the printer via the P2P channel, enabling the printer to access the target router.
