Wi-Fi Aware

Wi-Fi CERTIFIED Wi-Fi Aware™無需傳統網路基礎設施、互聯網連接或GPS信號,就能夠快速發現和連接其他Wi-Fi設備,並與這些設備進行資料交換,因此擴展了Wi-Fi®的功能。Wi-Fi Aware™基於用戶當前的位置和偏好建立獨立的、點對點的Wi-Fi連接,可提供豐富的當下體驗。

社交互動用例

  • 與附近的人建立連接,在移動設備上玩一款共同喜歡的遊戲;
  • 與附近的朋友一起收聽在其中一個使用者設備上播放的歌曲;
  • 在音樂會上發現朋友,分享照片或相約會面地點。

商業用例

  • 不用先登錄網路,就可以向印表機安全地發送檔;
  • 路過餐館、甚至在餐館未開門時,無需互聯網連接,就可查看餐館功能表並訂位元。

教育用例

  • 為參觀博物館、畫廊和實地考察的學生提供更好的教育體驗;
  • 實現學校簽到和點名自動化,並給簽到和點名加上時間戳記。

新出現的用例

  • 使自動駕駛和遙控車輛能夠立即感知其他設備並自動交換諸如GPS座標、高度、方向、擁有者身份等資訊。
  • 簡化機場安檢以及海關和移民局的處理流程,因為可以使用電子版駕照或護照等移動身份證件,而無需旅客出示實體身份證件。

Wi-Fi Aware豐富了個性化移動體驗

Wi-Fi Aware利用用戶的自發性接近實現創新應用。Wi-Fi Aware設備在建立關聯之前,不斷發現在用戶Wi-Fi範圍內的其他設備,因此,發現與用戶設定的偏好相匹配的資訊和服務變得容易了。這種技術支持真正的個性化社交、本地和移動體驗,可幫助用戶最為充分地利用其移動設備,甚至在擁擠的環境中也一樣。

主要特點:

  • 甚至在沒有GPS、蜂窩或基礎設施連接時,在建立關聯之前,利用Wi-Fi或藍牙低功耗無線信號以連續、節電方式進行設備至設備發現;
  • 同時多方位分享服務或資訊;
  • 動態連接,即使某部設備移動到連接範圍以外,通過Wi-Fi Aware連接的設備群也能夠保持連接;
  • 在室內和擁擠環境中運行良好;
  • 高效率設備至設備通信支援本機和基於IP的資料交換,每個資料流程都與特定應用或服務相關聯;
  • 基於使用者的隱私控制,使使用者能夠通過設備作業系統或應用選擇是否披露身份資訊。

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.

  • What is the Wi-Fi Alliance specification underlying Wi-Fi Aware?

    Wi-Fi Aware is a certification program based on the Wi-Fi Alliance Neighbor Awareness Networking Technical Specification.

  • 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. ​
