Written by prodigitalweb

Are you a Xiaomi Smartphone user? Then, you must have seen the term Wfd Service on your mobile device. However, many people still don’t understand what this service is, what is the need to use it, etc. Apart from this, plenty of other default apps are also available on Xiaomi phones about which they don’t have any type of knowledge. Do you also want to know what the app is, why it is used, etc.? Then, you have come to the right place. In this article, we have given elaborated details regarding the application.

What Is The Wfd Service App?

Wfd service is an internal application of Xiaomi Smartphones. It is known as Wi-Fi Direct Service. It is one of the vital apps that are available on the Xiaomi models along with its MIUI system. Using this App feature, people can connect their Xiaomi mobile devices to other Wi-Fi-Direct enabled devices as well as smart devices wirelessly. With the help of WLAN Direct, you can connect devices with each other and you don’t need to take the help of a wireless router.

It is such an app that only Xiaomi mobile device users can use. People know them also as Wi-Fi Direct Service. Xiaomi is the largest Smartphone manufacturing company in China. This company is ranked 4th all over the world. These mobile devices are generally famous for awesome specifications and “near to cost” prices.

Wi-Fi Direct Service is one of the quality specs these phones have. With the help of this feature, these phone models control the link between them via Wi-Fi networks. The feature also enables you to set up the Wi-Fi connection of your device so that you can access your network connection.

Nowadays, this feature is available in almost all the latest phones that help to make a connection with another phone directly. However, in order to do so, the phone needs to be present in the same Wi-Fi network or private hotspot. Thus, you can merely transfer files directly. It is recommended to leave the system feature as it is. Otherwise, there is a probability that your device won’t function properly.

About The App:

In recent times, each person has an individual Smartphone. Among them, multiple people use Android devices also. Xiaomi is also one of these that has its specific features like Wi-Fi Direct service. One device can connect to other devices without taking the help of any home network connection. With the help of this specific feature, you can share music, pictures, documents, and many more. What makes it special is that it allows you to watch TV without using a network connection.

Before its availability in the market, people used to use third-party apps such as Shareit, Zapya, Xender, etc. However, they didn’t face any troubles while using these apps as they were able to transfer files with them. The only drawback of these apps is that people need a Wi-Fi router or any network connection to operate them.

It is actually a lightning fast file-transfer service. You can share files with a speed up to 250 megabits per second using the feature. There doesn’t exist any risk while using this feature as it is a well-secured file transfer method. However, you need to ensure that the two devices you are using to connect need to be available within the distance of 200m. In short, it is a very useful technology using which you can transfer essential files from one mobile to another. However, the feature is not available in the devices such as Samsung, iPhones, etc. If it exists, then it will be very helpful for the users.

What is Wi-Fi Direct (WFD) Protocol?

In proximity extension, the devices running in the same application can establish direct connection between them. They do not need any intermediary applications such as wireless access point WAP to connect. This application to application protocol is called as Wi-Fi Direct (Wi-Fi Peer-to-Peer). 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.

What Is WiFi Direct?

It is a connection that allows communication from one device to another, and helps to link devices together without using a nearby centralized network. In this case, one device will work as an access point. Another device connected to this device uses WPS and WPA/WPA2 security protocols. You should know that WPS stands for Wi-Fi Protected Setup. On the other hand, WPA stands for Wi-Fi Protected Access. This technology was invented in the beginning of the 2000s. Then, it was incorporated into devices.

At a glance, you may find this technology similar to Bluetooth. But you should know that there are a few important differences between these two. The most interesting thing about this technology is that it is capable of handling more information at a higher speed compared to Bluetooth — nearly ten times the rate in optimal conditions.  A peer-to-peer connection helps to transmit data-rich content, such as a video or a picture of high resolution. In such cases, direct Wi-Fi technology is beneficial. It is also a great option when the Wi-Fi network is down.

The benefit of this technology is how versatile it can be where there will be no Wi-Fi network that can serve as a go-between for devices.  Multiple devices are able to connect to each other and are capable of sharing crucial files in casual settings without any security worries.

Devices Supported By Wi-Fi Direct:

It has been a decade now, at least, since consumers have access to this technology. All credits go to the 2011 Digital Living Network Alliance update that came with several guidelines for the feature. Now, so many compatible devices are available, even those you may not have expected. Since the release of the Android 2.3 version, Android devices continue to be compatible with this technology. And since the release of iOS 7, Apple devices have supported it.

Several entertainment devices use Direct to stream screencasts or content from a smartphone. Multiple smart TVs support this technology. Moreover, several peripherals that offer wireless connections use Wi-Fi Direct technology, rather than using Bluetooth. Additionally, devices like wireless headsets and wireless printers use this technology.

How Wi-Fi Direct can be created depends on your device type. A few devices ask you to scan a QR code. On the other hand, you need to enter a numerical PIN on a few devices. In some cases, you are capable of connecting devices by pressing physical buttons. The more time goes by, the more important security becomes. As a result, you can see the use of the combination of these techniques in more devices and fewer devices will connect automatically.

How Does Wi-Fi Direct Work?

Wireless Android devices are able to search for the available nearby Wi-Fi Direct devices using this technology. Once an Android model finds nearby devices, it can connect with them. Suppose you use this technology to share a file. In that case, your Android smartphone searches for the available smartphones that support the technology. Once your smartphone finds this, it will show it on the sourced device. You now need to click on the designation device, which you can see available on your smartphone, to connect it. After that, you will be able to start your file-sharing task easily.
