What device is DIRECT?

DIRECT refers to Wi-Fi Direct, a new technology that does not require a router; the Wi-Fi Direct standard refers to allowing devices in a wireless network to connect to each other without going through a wireless router; similar to Bluetooth technology , this standard allows wireless devices to be interconnected in a point-to-point manner, and is significantly improved than Bluetooth in terms of transmission speed and transmission distance.

What is DIRECT?

Direct router refers to WI-FI direct, which is a new technology that does not require a router. In October 2010, Wi-Fi Alliance (wi-fi Alliance) released the Wi-Fi Direct white paper. The white paper introduces basic information about this technology, its characteristics and functions. The Wi-Fi Direct standard allows devices in a wireless network to connect to each other without going through a wireless router. 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. By definition, Wi-Fi CERTIFIED Wi-Fi Direct devices are devices that support peer-to-peer connections. Such devices support both infrastructure networks and P2P connections. Wi-Fi Direct devices can join the infrastructure network as a typical station (STA) and must support the Wi-Fi Protected Setup joiner function.

By definition, Wi-Fi CERTIFIEDWi-Fi Direct devices are devices that support peer-to-peer connections. This device supports both infrastructure networks and P2P connections. Wi-Fi Direct devices can join the infrastructure network as a typical station (STA) and must support the Wi-Fi Protected Setup joiner function.

Wi-Fi Direct devices establish connections by forming groups (in a one-to-one or one-to-many topology) that work similarly to infrastructure BSS. One Wi-Fi Direct device is responsible for the entire group, including controlling which devices join, when the group starts and terminates, etc. This device is an access point to traditional customer equipment and can provide some of the services provided by infrastructure access points.

Initially, this new standard of the Wi-Fi Alliance® alliance was originally called "Wi-Fi peer-to-peer", but was eventually named WiFiDirect, targeting various Wi-Fi devices, from computers to mobile phones, to computer peripherals, to home appliances, etc. Devices that comply with this standard can easily connect directly to other devices to transmit data or share applications without the need for hotspots or routers. Wi-Fi Direct can support one-to-one direct connection or multiple devices can be connected at the same time, and the Wi-Fi Direct standard will support all Wi-Fi devices, from 11a/b/g to 11n, Wi-Fi of different standards Fi devices can also be directly interconnected.
