Wi-Fi Aware

發現附近的世界

Wi-Fi CERTIFIED Wi-Fi Aware™是Wi-Fi Alliance®的一個認證計畫, 它可以在不需要傳統的Wi-Fi網路基礎設施、網路連接或GPS信號的情況下,通過快速發現、連接和與其他Wi-Fi設備資料交換的方式來擴展Wi-Fi®的功能。Wi-Fi Aware™是基於用戶的即時位置和偏好,通過建立獨立的、點對點的連接為用戶提供豐富的即時體驗。

  • 與附近的人聯繫,在移動設備上玩喜歡的遊戲
  • 管理會議日程和地點,或在展會上引起其他與會者注意
  • 在逛街時,收到精選零售商的優惠券和通知
  • 為參觀博物館的人帶來具有教育意義的體驗
  • 在音樂會上查找好友,分享照片或約定見面地點

Wi-Fi Aware在關聯之前持續發現用戶Wi-Fi範圍內的其它設備,説明使用者輕易地找到在附近與自己偏好匹配的資訊和服務,為使用者提供更有趣、更相關、更高效的移動體驗。地鐵站裡的個人可以與附近的人連線玩遊戲,同時可以在不需要網路連接的情況下接收列車時刻表的更新。午餐休息時,用戶可以在與同事通過建立獨立的對等連接分享照片的同時維持與公司網路連結。

Wi-Fi Aware是推動真正個性化的社交、本地和移動體驗的關鍵因素,它適用於擁擠的環境中。Wi-Fi Aware已準備好大規模採用,並且在Android Oreo作業系統中可以使用本地的支援。

Wi-Fi Aware豐富個性化的移動體驗

  • 在關聯之前,即使沒有GPS、蜂窩或基礎設施連接,也可以提供連續的設備到設備的發現
  • 允許同時進行多方向的服務或資訊共用
  • 動態功能;即使一個設備移出範圍,通過Wi-Fi Aware連接的設備組也保持它們的連接
  • 在室內和擁擠的環境中工作良好
  • 能夠實現設備到設備的高效通信;每個資料流程都與特定的應用程式或服務相關聯
  • 提供用戶隱私控制;通過作業系統或應用程式選擇加入或退出身份披露
  • 充分利用用戶的自發性,實現創新應用

基於 Wi-Fi CERTIFIED™計畫的強大優勢, 使用者可以信任 Wi-Fi Aware設備在眾多設備品牌中運行良好。

Frequently Asked Questions
  • What is Wi-Fi Aware?

    Wi-Fi Aware incorporates capabilities enhancing peer-to-peer communications by enabling devices to exchange services and information 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-enabled 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 are capable of receiving updates to support Wi-Fi Aware. Whether a device can receive software updates to add the new functionality or not comes down to individual device vendor implementation. Native support for Wi-Fi Aware is available in the Android Oreo 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 today. 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 used 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 whereas 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.
