[簡易開箱] 802.11ac 極速無線初體驗 Netgear R6300

 話說今年四月底 數位天堂粉絲團 即已對全球首款支援 802.11ac 規格的 Router - Netgear R6300 無線路由器給予關注,根據 802.11ac 的規範,802.11ac 採用相對純淨干擾較低的 5GHz 為傳輸無線頻段,最大傳輸能力可達 1300Mbps,堪稱為 Giga 等級的無線網路傳輸規格,此規範一出令眾人引領期盼。這次有幸透過友人的協助拿到尚未正式進口的 Netgear R6300,面對號稱地表最強的 Gigabit 等級的無線傳輸規格,其實內心激動不已,就像美國 NASA 太空總署若請車神舒馬克試飛最新型太空梭,相信老舒應該也是此等心情吧 blushing


簡易開箱
Netgear R6300 無線路由器是新一代推出支援 802.11ac 無線同步雙頻路由器,Netgear R6300 雙頻合併最大頻寬可達 450Mbps + 1300Mbps 的傳輸能力,並且可與現有的 802.11a/b/g/n 向下相容,此外內建 4 個 Gigabit 埠提供超高速區網連線能力及 2 個 USB 2.0 界面,可外接 USB 磁碟或 USB 印表機,當成網路分享中心。

因這次只有短暫的接觸就必須歸還,待日後若有長時間測試機會,我們再做深入介紹,以下就簡單的幾張開箱照片分享給大家參考。

硬體規格
‧ CPU: Broadcom BCM4706 600MHz
‧ Flash: 128MB
‧ RAM: 128MB
‧ 802.11 b/g/n 2.4 GHz
‧ 802.11 a/n/ac 5.0 GHz
‧ 5x 10/100/1000 (1 WAN and 4 LAN) Gigabit Ethernet ports 
‧ 2x USB 2.0 ports

無線 802.11ac 傳輸測試
因這次只有短暫的時間測試就必須歸還廠商,所以只好將大家比較關切的無線傳輸速度做個測試,但目前市場上還買不到 802.11ac 無線網卡,測試計畫是以兩台 Netgear R6300 跑 bridge mode 對連,藉以測出 802.11ac 的傳輸能力,測試架構請參考底下連線架構,左方為 Router 端,右方為 Bridge 端。

測試心得
短暫的 802.11ac 初體驗,測試出來的速度的確令人驚艷,透過 Netgear R6300 內建的 Bridge 模式,連線速度雖然離 1300Mbps 的理論值還有一段距離,不過這樣的傳輸速度已經是前所未見的快,大致上已俱備 Gigabit 區網的水準,相信日後 802.11ac 終端裝置日漸普及後,Gigabit 無線網路將指日可待。
