Wi-Fi Direct (English: Wi-Fi Direct), once known as Wi-Fi Peer-to-Peer, is a set of software protocols that refers to Allows devices on a wireless network to connect to each other without going through a wireless router.

wifi direct allows wifi devices to connect directly to another wifi device in a point-to-point manner for high-speed data transmission without going through a wireless network base station (Access Point). This protocol is developed, supported and certified by the Wi-Fi Alliance. Products that pass certification will receive the Wi-Fi Certified Wi-Fi Direct mark.

Its main opponent is the Bluetooth 3.0 protocol.

WiFi Direct is similar to Bluetooth technology. This standard allows wireless devices to interconnect in a point-to-point manner, and is significantly improved than Bluetooth in terms of transmission speed and transmission distance.

History:

On October 14, 2009, the Wi-Fi Alliance announced that they were developing this protocol. Public certification officially started on October 25, 2010. Currently, Atheros, Broadcom, Intel, Ralink, Realtek and other manufacturers have passed certification and are preparing to release products with Wi-Fi Direct functionality.

Wi-Fi Direct architecture is based on the original 802.11a, 802.11g, 802.11n, and does not support 802.11b. It is faster than the existing ad-hoc mode and also supports WPA2 encryption mechanism. The maximum transmission distance is 200 meters, the maximum transmission speed is 250Mbps, and the 2.4GHz and 5GHz frequency bands are used. It supports one-to-one and one-to-many modes.

Because it is a software protocol, in theory, old Wi-Fi devices may gain compatibility through firmware and software upgrades, but the Wi-Fi Alliance does not guarantee that chip manufacturers will support the upgrade.

Wi-Fi Direct logo

Devices with the Wi-Fi Direct logo support a breakthrough new technology that enables Wi-Fi The direct interconnection of Fi devices helps users complete tasks such as printing, sharing, synchronization and display in a simpler and more convenient way.

Products bearing the Wi-Fi CERTIFIED Wi-Fi Direct logo can connect to each other without joining a traditional home, office or hotspot network. Using this technology, mobile phones, cameras, printers, PCs and gaming devices will be able to connect directly to each other to quickly and easily transfer content and share applications.
