[802.11ac] ASUS RT-AC66U 及 PCE-AC66 無線黃金組合開箱評測(下)
作者:Aven 日期:2013-03-28 01:23
這次的測試過程可說是一波三折，原先以為 ASUS 提供測試的是 USB 介面的無線網卡，待正式拆封後才知道是 PCI-E 1x 介面的網卡，因筆者手上的電腦不是筆電就是 EeeBOX 等輕薄 PC 為主的桌機，這些電腦都無法接 PCE-AC66 測試，好不容易找到一台 Acer H340 的 NAS 內建有 PCI-E 插槽，可是似乎是相容性的問題，接上 PCE-AC66 後一開機就當了，最後只好向友人商借一台 ASUS CP6130 桌機，才順利完成測試工作。
測試環境：
Server：QNAP TS-459 Pro+
Client：ASUS CP6130
我們設定的環境是以一台 NAS 當 Server，接於 RT-AC66U 的 LAN port，另一台桌機則採用 ASUS CP6130 安裝 PCE-AC66 無線網卡當成 Client。Server 及 Client 兩者之間的直線距離約三公尺(中間無明顯障礙物)，同時測試 5GHz 及 2.4GHz iperf 傳輸效率，供大家參考。
5GHz 頻段 Client to Server：437Mbps

測試心得
依過去的測試經驗 802.11ac 傳輸瓶頸通常落在網卡介接規格上，而 ASUS PCE-AC66 採用了 PCI-E 介面改善了USB 2.0 傳輸瓶頸。不過就如同筆者前面所提到的測試窘境，PCI-E 等內接式介面未必是最普及的選擇，畢竟用筆電取代桌機的人也不在少數，更何況對一般使用者而言，若需要拆機才能夠安裝無線網卡，相對地也提高了使用者的購買意願及門檻，建議 ASUS 未來也能顧及多數使用者的環境，提供 USB 3.0 介面的 802.11ac 無線網卡。
雖然如此，筆者還是認為 RT-AC66U 無線路由器及 PCE-AC66 無線網路卡的搭配組合，已經突破以往的測試數據，實際測試傳輸速率可達到 400Mbps 以上，以現階段市場上各家推出的 802.11ac 組合商品而言，兩者的搭檔堪稱是無線 AC 黃金組合，適合有巨量資料需要無線傳輸需求的用戶參考。
