Wi-Fi Direct并不是什么新鲜事，但越来越多的人终于开始了解它以及它可以做什么，这与该平台不断增长的设备支持有很大关系。你看，这个概念就是在不需要无线路由器的情况下创建对等 Wi-Fi 连接。您可能会说这是不可能的，但简单的事实是，事实并非如此，而且我们多年来一直在这样做。简单来说，Wi-Fi Direct很像蓝牙(Bluetooth)，因为人们可以跨设备共享文件，甚至可以通过支持的无线耳机收听音乐。
如果此时您家中有Roku设备，那么它很可能支持开箱即用的Wi-Fi Direct 。Roku没有使用IR 发射器(IR blaster)与遥控器进行通信，而是依靠Wi-Fi Direct，而且效果很好。
好消息是，当设备相互通信时，用户不需要输入Wi-Fi密码。(Wi-Fi)整个过程是自动的，这也是许多人不知道他们将Wi-Fi用于某些硬件功能而不是蓝牙(Bluetooth)的原因之一。
目前，几乎所有 Windows 10 设备都支持Wi-Fi Direct。您只需要受支持的第三方硬件即可利用它所提供的功能。事实上，我们相信第一批Xbox One控制器只能通过该平台无线连接到系统。
将此功能内置到计算机和其他类型的硬件中可以制造出更实惠的产品。制造商无需添加蓝牙(Bluetooth)无线电，只需利用Wi-Fi无线电进行无线通信即可。
什么是 Wi-Fi Direct 连接
Wi-Fi Direct连接只需一台设备即可与Wi-Fi Direct设备兼容。为此，Wi-Fi Direct与(Wi-Fi Direct)Wi-Fi Protected Setup系统协商链接，该系统为每个设备分配一个有限的无线接入点。Wi-Fi Direct使该设备成为接入点并与其他设备连接。其他设备可以是平板电脑、PC 或移动设备，甚至来自不同的制造商。可以通过按下一个或所有设备上的按钮来建立其他设备与兼容设备的配对。
然后，兼容设备会创建一个可以建立对等连接的新 Wi-Fi 网络。该连接支持在连接设备之间进行数据传输，且设置要求最低。
此过程为所有连接的设备提供标准Wi-Fi协议，无需繁琐的设置程序即可相互交互。这些设置过程也无需指定Wi-Fi密码。
Wi-Fi Direct附带Wi-Fi 联盟(Wi-Fi Alliance)，该联盟是负责认证 Wi-Fi 套件的全球行业协会。因此，Wi-Fi Direct连接技术得到了其他人的支持，不需要任何特殊的硬件。
它消除了对接入点的要求(It eliminates the requirement for the access point)
Wi-Fi Direct 连接不需要无线接入点，因此无需路由器。它像蓝牙(Bluetooth)一样运行，唯一的区别是高速和长距离。它的速度不仅可以实现更快的互联网浏览，还可以实现文件传输。它同时提供以更高的速度与一个或多个设备进行通信。
Wi-Fi Direct设备不需要路由器或其他接入点的原因是它会根据设备的可用性在需要时形成其 ad-hoc 网络。
它消除了对互联网连接的要求(It eliminates the requirement for an internet connection)
Wi-Fi Direct提供没有有效互联网连接的Wi-Fi 。借助Wi-Fi Direct，您可以连接各种设备，例如打印机、手机、电视和另一台 PC。该连接不需要有效的互联网。使用Wi-Fi Direct，可以轻松地将手机中的图像、文件和视频共享到电视
这是一个受保护的网络(It is a Protected network)
Wi-Fi Direct连接使用Wi-Fi Protected Setup和WPA2。因此，其他人无法在未经授权的情况下连接到您的网络，并且您可以防止未经授权的通信来保护您的隐私。虽然可以通过多种方式安全地将设备连接到兼容设备。在物理上，可以通过按小工具 X 上的按钮，然后在小工具 Y 上按相同的按钮来完成，带有 PIN 码和 QR 码。
它识别附近的设备(It identifies devices nearby)
Wi-Fi Direct 提供 Wi-Fi Direct 设备发现(Direct Device Discovery)和服务(Service)发现。兼容设备可以识别其他设备。例如，如果您要打印并选择打印选项，则连接到打印机的设备将由兼容设备识别。
在您连接之前进行此过程非常重要，因为它可以确保有效利用时间。
它支持Wi-Fi收音机(It supports Wi-Fi Radio)
Wi-Fi Direct连接也是标准Wi-Fi无线电的一部分。制造商不需要为他们的设备添加额外的无线电。此外，可以使Wi-Fi Direct向后兼容。(Direct)
这些是该平台迄今为止使用的标准：
- 无线上网
- Wi-Fi Direct 设备(Direct Device)和服务发现(Service Discovery)
- Wi-Fi 保护设置
- WPA2
到目前为止， Wi-Fi Direct的用途是什么
好的，所以你可能想知道我们可以用它做多少事情。正如我们上面提到的，它可用于跨不同设备共享文件。例如，在两台 Windows 10 笔记本电脑之间或从Android(Android)手机到 PC之间共享一堆图片。
问题是，与使用蓝牙(Bluetooth)相比，它并不容易，现在可以理解。它仍然相当新，尚未成熟。但是，我们相信 Wi-Fi Direct在不久的将来会变得非常重要。
是的，它已经在工作了，但它并不可靠，以至于普通人无需像我们这样的专家就可以使用它。
检查您的设备是否与 Wi-Fi Direct兼容
这非常容易。在管理员(Administrator)模式下启动命令提示符(Command Prompt)，然后键入ipconfig (Fire)ipconfig /all并按 Enter 键。
查找Microsoft Wi-Fi Direct Virtual Adapter以确认对Wi-Fi Direct的支持。
一旦您知道您的 PC 安装了兼容适配器，您就可以在Windows 10 PC上设置 Wi-Fi Direct连接。
如何在 Windows 10 上添加 Wi-Fi Direct设备(Direct)
以下是步骤：

What is Wi-Fi Direct and how to tell if your computer supports it
Wi-Fi Direct is nothing new, but more people are finally learning of it and what it can do, and that has a lot to do with the growing device support for the platform. You see, the concept is all about creating a peer-to-peer Wi-Fi connection without the need for a wireless router. You may say this is impossible, but the simple truth is, it’s not, and we’ve been doing it for years. In simple terms, Wi-Fi Direct is a lot like Bluetooth since folks can share files across devices, and even listen to music from supported wireless headphones.
If you have a Roku device in your home right at this moment, then chances are, it supports Wi-Fi Direct right out of the box. Instead of using an IR blaster to communicate with the remote control, Roku relies on Wi-Fi Direct, and it works quite well.
The good news is, the user is not required to enter a Wi-Fi password when its time to have devices communicate with each other. The entire process is automatic, which is one of the reasons many people have no idea they are using Wi-Fi for certain hardware features instead of Bluetooth.
Right now, almost all Windows 10 devices have support for Wi-Fi Direct. You will only require supported third-party hardware to take advantage of what it has to offer. In fact, we believe the first Xbox One controllers could only connect to the system wirelessly via the platform.
Having this feature built into the computer and other types of hardware could make for more affordable products. Instead of having to add a Bluetooth radio, manufacturers could simply take advantage of the Wi-Fi radio for wireless communication.
What is Wi-Fi Direct connection
Wi-Fi Direct connection needs only one device to be compliant with the Wi-Fi Direct devices. For this, Wi-Fi Direct negotiates the link with a Wi-Fi Protected Setup system which assigns each device a limited wireless access point. Wi-Fi Direct enables this device to become an access point and connect with other devices. Other devices can be a tablet or PC or a mobile, even from a different manufacturer. The pairing of other devices with the compliant device can be established by pressing a button on one or all the devices.
The compliant device then creates a new Wi-Fi network that can establish a peer-to-peer connection. The connection enables data transfer between connected devices with minimal setup requirements.
This process provides all the connected devices with standard Wi-Fi protocols without the requirement for cumbersome set-up procedures to interact with each other. These set-up procedures also exclude the need to specify Wi-Fi passphrases.
Wi-Fi Direct comes with the Wi-Fi Alliance which is the global industry association in charge of certifying the Wi-Fi kit. Thus, the technology of Wi-Fi Direct connection is supported by others and doesn’t require any special hardware.
It eliminates the requirement for the access point
Wi-Fi Direct connection does not require a wireless access point, thus eliminating the need of a router. It operates like Bluetooth with the only difference between high speed and longer range. Its speed not only enables faster internet browsing but also file transfers. It simultaneously offers to communicate with one or more devices at a higher speed.
The reason Wi-Fi Direct device doesn’t require router or other access points is that it forms its ad-hoc networks, as and when required depending upon the availability of the devices.
It eliminates the requirement for an internet connection
Wi-Fi Direct offers Wi-Fi without an active internet connection. With the help of Wi-Fi Direct, you can connect various devices such as the printer, mobile, T.V, and another PC. The connection does not require an active internet. With Wi-Fi Direct it is easy to share images, files, and videos from your mobile to your T.V.
It is a Protected network
Wi-Fi Direct connection uses Wi-Fi Protected Setup and WPA2. As a result, others cannot connect to your network without authorization, and you can prevent unauthorized communications from safeguarding your privacy. While connecting devices to the compliant device can be done securely in numerous ways. Physically, it can be done pressing the button on gadget X and then same on gadget Y, with pin codes and QR codes.
It identifies devices nearby
Wi-Fi Direct offers Wi-Fi Direct Device Discovery and Service discovery. The compliant device can identify other devices. For example, if you want to print and you select the print option, the device that is connected to the printers will be identified by the compliant device.
It is highly important that this process takes place before you get connected as it would ensure efficient utilization of time.
It supports Wi-Fi Radio
Wi-Fi Direct connection is also a part of the standard Wi-Fi radio. It is not required for manufacturers to add extra radios to their devices. Moreover, Wi-Fi Direct can be made compatible backward.
These are the standards used by the platform so far:
- Wi-Fi
- Wi-Fi Direct Device and Service Discovery
- Wi-Fi Protected Setup
- WPA2
What are the uses of Wi-Fi Direct thus far
OK, so you might be wondering about the number of things we can do with this. As we’ve mentioned above, it can be used for sharing files across different devices. For example, sharing a bunch of pictures between two of your Windows 10 laptops, or from your Android phone to your PC.
The problem is, it’s not as easy when compared to using Bluetooth, and that’s understandable right now. It’s still fairly new and has yet to reach maturity. However, we believe Wi-Fi Direct will become very important in the near future.
Yes, its already working, but it’s not ye reliable to the point where normal folks can use it without having to call for a specialist like ourselves.
Check if your device is Wi-Fi Direct compatible
This is super easy. Fire up the Command Prompt in Administrator mode, then type ipconfig /all and hit the Enter key.
Look for Microsoft Wi-Fi Direct Virtual Adapter to confirm the support for Wi-Fi Direct.
Once you know that your PC has the compatible adapter installed, you can set up the Wi-Fi Direct connection on the Windows 10 PC.
How to add a Wi-Fi Direct device on Windows 10
Here are the steps:
- Step 1: Go to ‘Settings’ on your PC or laptop.
- Step 2: Go to ‘Network & Internet’.
- Step 3: In the Network, select the Wi-Fi Direct Option, by clicking it “ON”. Your Windows 10 PC will start searching for the available Wi-Fi Direct connection. When the scanning is complete, the name of your Wi-Fi Direct connection will be displayed on the screen. Select the desired Wi-Fi Direct connection.
- Step 4: For authorization, the system will ask you for a password. Enter the respective credentials, and your system is all set as a compliant Wi-Fi device. Now you can easily pair other devices to your Windows 10 PC and enjoy the high-speed internet without any wires or router as the access point.
In short, if you want to add a Wi-Fi Direct device to your Windows 10 computer system, then open the Settings app by clicking on the Windows key + I. After that, navigate to Devices > Bluetooth & other devices > Add Bluetooth or other devices.
Finally, select Everything else, then add the device you wish to connect with.
How to pair other devices with Windows 10 PC using Wi-Fi Direct
To pair Windows 10 PC with other compatible devices, go to Settings. Click on the Wi-Fi Direct menu. A drop-down menu under the “Discovered Devices” tab is displayed with the list of all the devices. Select the device you wish to pair with Windows 10 PC and press ‘Connect’.
Select the network name you created in the compliant device as a Wi-Fi Direct network and connect to it. Enter the passcode to connect to the network. The network will remain active until you disconnect it or turn off the computer. It will be re-enabled only when done manually. Wi-Fi Direct can be activated on multiple devices at a time by simply selecting all the devices together, and you can form a Wi-Fi Direct group.
That’s it.
