    Aruba 800 Switch與Aruba 52 Access Points測試報告Aruba 800 Switch與Aruba 52 Access Points測試報告

    作者:陳世揚 工研院交大網路測試中心Aruba Networks推出的方案要讓企業更樂於導入WLAN設備,它能集中化管理許多AP,具有動態RF能力、安全控管與IDP能力,NBL這次評估的Aruba 800和Aruba 52的確實令我們看到它的優異之處。

    NBL Review Highlights1.具備圖形化的RF規劃,其APM能動態配置Channel與Power Level2.實現RF Heat Maps(等強度涵蓋圖)能及時顯示AP的部署情形3.能識別是否有危險的AP,並偵測Ad-Hoc、Wireless Bridge和多種攻擊4.可定位無線裝置,並精確到3公尺範圍以內5.能依不同身分,給予如地點、時間、頻寬合約、與應用協定等的控管6.支援WPA連線的Seamless漫遊,甚至在使用Switch失效備援的情況下
