TR-398 Issue 2 & Issue 3 WiFi Testing with LANforge
TR-398 Issue 2 & Issue 3 WiFi Testing with LANforge
Broadband forum的TR-398 WiFi Performance test plan提供了一套全面的測試,可驗證住宅和小型辦公室室內環境中部署的WiFi無線存取點(AP)的性能,包含網路性能、吞吐量、連接穩定度、公平時間調度(Airtime Fairness)和長期穩定性,綜合性的測試項目涵蓋絕大部分的測試領域。TR-398 Issue 2增加新測試項目,包含雙頻吞吐量(Dual Band Throughput)、雙向吞吐量(Bi-directional Throughput) 以及802.11ax-高峰性能表現(Peak performance)和頻道自動選擇測試(Automatic Channel Selection),TR-398 Issue 2可適用於所有 802.11ax以及舊有的802.11n/ac模式。而TR-398 Issue 3相較於TR-398 Issue 1 & TR-398 Issue 2包含了新的測試應用,TR-398 Issue 3中的新測試應用包含:負載下的延遲(Latency-under-Load)、服務品質(QoS)、多頻段吞吐量(Multi-Band throughput)、Mesh測試、並支援6E以及測試平台的自動校準,此自動化程式可讓用戶自定義測試內容,包含執行和通過/不通過指標。(Broadband Forum的 TR-398 Issue 3 文件仍在進行中。)
此測試解決方案可提供設備供應商,在進行部署WiFi AP前對實驗室中的AP進行確認,以供設備製造商在AP的開發過程中進行測試。
Candela Technologies提供自動化的TR-398測試系統,以合理的價格和解決方案提供所有必需的測試硬體,包括多個無線終端模擬器、流量產生器、RF外箱、控轉盤、可編程衰減器和全自動測試軟體以及PASS / FAIL結果報告,簡單的操作即可滿足測試且可獲取All in one的測試報告。
