AirMac Extreme ME918J/A ベンチマーク

MacBook Pro 新調にともない、802.11ac 対応のAirMac Extreme(ME918J/A)を入手しました。 

 Half mini PCI 802.11acカードが流通していれば、自作のAccess Pointに組み込んだのですが、しばらく流通の目処が立たないので。。

ローカルネットワークのファイルサーバーへのファイルアクセスについて、有線とAirMac Extremeで無線接続を行った場合のスピード比較を行いました。

有線はもちろん、1000Base-Tですが、MacBook Pro Retina model Late2013 には1000Base-Tの口がありませんから、Thunderbolt-Erthernet変換アダプタを利用しました。

Samba 4.0系でのベンチマークです。

802.11a のアクセスポイントと比べて、全体的にパフォーマンスが上がっています。

SNMPが仕様から省かれてしまっているのが残念ですが、電源内蔵やビームフォーミングなど魅力も満載です。
