第七章 各型學校行動學習無線網路最佳佈建建議方案 7.1 大型學校以名間國中為例
充分利用 2. 4GHz 及 5GHz 電波的特色，分配如下：
2.5 GHz 頻段
可以確保網路傳輸速率，且頻道相對較多且寬，可確保教學的順暢，可做為教 學之用。
二.每個地方最佳的無線電波頻道分配
1.2.4GHz
頻段
2.4GHz
的無線電波就只有
3個乾淨的
20MHz
頻道可用，要有最佳的利用那麼看
起就應該像右圖。
2.5GHz
頻段
5GHz
部分在
WiFi分析儀看起來應該 像下圖這個樣子才會有最佳的傳輸速率。
台灣目前已全部開放計有
CH36、CH40、CH44、CH48、CH52、CH56、CH60、CH64、CH100、CH104、CH108、CH112、CH116、CH120、CH124、
CH128、CH132、CH136、CH140、CH149、CH153、CH157、CH161、CH165
共
計
24個頻寬
20MHz的乾淨頻道，如下圖所示。
33
其中
CH100~CH140共
11個頻道必須具 備
DFS(自動跳頻)，CH52~CH64共
4個頻道
如具備
DFS(自動跳頻)則可在室外使用。另外頻寬
40MHz的頻道共有
11個，頻
寬
80MHz的頻道共有５個。基本上
5GHz部
分因為穿透力不佳大約隔一間教室(兩道牆)或 一層樓(樓地板比較厚)就沒有訊號了！因此為 因應時代的趨勢，應選購至少支援
Band 2~4的無線基地台才能調成任何一個地方同一頻 道只有一台無線基地台使用
(802.11ac@80MHz)。
三.提昇學校有線網路佈建品質
本計畫所列學校機房有線網路建置情形 如圖所示，不僅是維護不易、不够美觀……
等外在表現而已，更因線路的扭曲、彎折影 響日後網路的傳輸速率，進而降低教學效率
與順暢，建請教育部寬列經費至少提升至如右圖的佈建品質。
四.持續規畫校園行動教學無線網路架構與輔導
本計畫執行期間雖為一年，然實際進行行動學習無線網路最佳佈建建議方案 探討時間不足，僅依目前市面上主流行動裝置進行各種無線網路標準下實際傳輸 速度測試，並沒有進行下列各項實測：
1.不同等級的行動裝置其網路傳輸速率。
2.行動學習學校採用設備實際傳輸速率測試。
3.以行動學習學校採用設備作為行動載具進行整班上網無線網路實際總頻寬測試-
提供全班同時上網時無線網路可用總頻寬資訊。
4.以行動學習學校採用設備作為行動載具進行各型學校整班上網學術網路實際總
頻寬測試-提供全班同時上網時各校學術網路可用總頻寬資訊，學校可以知道該 申請多大的頻寬。
5.無線網路基地台等級。
建請教育部寬列經費進行上述各項測試並將成果與各校分享，各校如有須要最好
能有專人協助，降低校園行動學習無線網路建置門檻，營造處處有教材，時時有
學習，人人有成就的教育實境！
