Wi-Fi Aware

Wi-Fi CERTIFIED Wi-Fi Aware™无需传统网络基础设施、互联网连接或GPS信号,就能够快速发现和连接其他Wi-Fi设备,并与这些设备进行数据交换,因此扩展了Wi-Fi®的功能。Wi-Fi Aware™基于用户当前的位置和偏好建立独立的、点对点的Wi-Fi连接,可提供丰富的当下体验。


  • 与附近的人建立连接,在移动设备上玩一款共同喜欢的游戏;
  • 与附近的朋友一起收听在其中一个用户设备上播放的歌曲;
  • 在音乐会上发现朋友,分享照片或相约会面地点。


  • 不用先登录网络,就可以向打印机安全地发送文件;
  • 路过餐馆、甚至在餐馆未开门时,无需互联网连接,就可查看餐馆菜单并订位。


  • 为参观博物馆、画廊和实地考察的学生提供更好的教育体验;
  • 实现学校签到和点名自动化,并给签到和点名加上时间戳。


  • 使自动驾驶和遥控车辆能够立即感知其他设备并自动交换诸如GPS坐标、高度、方向、拥有者身份等信息。
  • 简化机场安检以及海关和移民局的处理流程,因为可以使用电子版驾照或护照等移动身份证件,而无需旅客出示实体身份证件。

Wi-Fi Aware丰富了个性化移动体验

Wi-Fi Aware利用用户的自发性接近实现创新应用。Wi-Fi Aware设备在建立关联之前,不断发现在用户Wi-Fi范围内的其他设备,因此,发现与用户设定的偏好相匹配的信息和服务变得容易了。这种技术支持真正的个性化社交、本地和移动体验,可帮助用户最为充分地利用其移动设备,甚至在拥挤的环境中也一样。


  • 甚至在没有GPS、蜂窝或基础设施连接时,在建立关联之前,利用Wi-Fi或蓝牙低功耗无线信号以连续、节电方式进行设备至设备发现;
  • 同时多方位分享服务或信息;
  • 动态连接,即使某部设备移动到连接范围以外,通过Wi-Fi Aware连接的设备群也能够保持连接;
  • 在室内和拥挤环境中运行良好;
  • 高效率设备至设备通信支持本机和基于IP的数据交换,每个数据流都与特定应用或服务相关联;
  • 基于用户的隐私控制,使用户能够通过设备操作系统或应用选择是否披露身份信息。

Frequently Asked Questions
  • What is Wi-Fi Aware?

    Wi-Fi Aware incorporates capabilities enhancing peer-to-peer communications by enabling devices to exchange information and services without the need for network infrastructure or sophisticated setup processes. Within Wi-Fi Aware networks, connections are contextually formed, creating a simple data exchange mechanism based on shared user preferences.​

  • How do users experience Wi-Fi Aware?

    Wi-Fi Aware mobile device experiences are application-driven; and users can control privacy settings and opt-in to desired notifications. Users can configure an application to offer and/or seek services on nearby devices.  

  • What is the range in which Wi-Fi Aware operates?

    Wi-Fi Aware operates at typical Wi-Fi range.

  • Will Wi-Fi Aware drain the battery on my mobile device?

    Wi-Fi Aware was designed to be power efficient by establishing independent networked “clusters” synchronized to a common “heartbeat” to exchange small messages about services available nearby. Continuous discovery occurs in the background without putting undue burden on the battery of a mobile device.

  • On what frequency bands does Wi-Fi Aware operate?

    Wi-Fi Aware operates in 2.4 GHz and 5 GHz. Discovery occurs in the 2.4 GHz band, channel 6 (discovery in 5 GHz is optional).

  • Can my device be updated to support Wi-Fi Aware?

    Many devices can receive updates to support Wi-Fi Aware. Whether a device can receive software updates to add the new functionality or not depends upon vendor implementation. Native support for Wi-Fi Aware is available in the Android O (and later) operating system.

  • What is the relationship between Wi-Fi Aware and Wi-Fi Direct?

    Wi-Fi Aware is a similar peer-to-peer connectivity technology to Wi-Fi Direct. However, while Wi-Fi Direct requires a centralized coordinator, called a Group Owner, Wi-Fi Aware creates decentralized, dynamic peer-to-peer connections. Many applications, such as Miracast and direct printer connections, work well with Wi-Fi Direct. Wi-Fi Aware is positioned to provide peer-to-peer connectivity in highly mobile environments, where devices join or leave in a less deterministic manner. Whether it's professionals at a crowded conference to find each other or strangers on a subway momentarily joining a multi-player game, Wi-Fi Aware connections seamlessly adapt to changing environment and usage conditions. 

  • What is the difference between Wi-Fi Aware and Wi-Fi Location?

    Wi-Fi CERTIFIED Location™ is used for determining device location within a network by finding and connecting to access points, whereas Wi-Fi Aware is about connecting directly to other devices to publish and advertise information and services without an access point. Wi-Fi Location™ and Wi-Fi Aware can be utilized for similar uses, such as geo-fencing or personalized shopping, but Wi-Fi Location is meant to operate within Wi-Fi infrastructure to deliver precise location determination. Wi-Fi Aware is focused on connecting devices within an area of proximity without a network infrastructure.

  • Why use Wi-Fi Aware over other connectivity technologies?

    Wi-Fi Aware has a longer range than other commonly used technologies. Proximity-based applications are more useful when the connection allows for a longer range. Additionally, once connected, devices can leverage the high-performance, fast speeds, and a high level of security that Wi-Fi delivers. The latest enhancements to Wi-Fi Aware also offer discovery by Bluetooth LE, which will trigger a formal Wi-Fi Aware session by first waking the Wi-Fi radio.

  • What operating systems support Wi-Fi Aware?

    Native support is available in the Android™ O (and later) operating system.

  • What are the latest features that are available in Wi-Fi Aware as of today?

    Wi-Fi Aware incorporates enhanced power savings, service discovery, Bluetooth Low Energy triggered initialization, device ranging, as well as native and IP-based data transfer. ​
