    "body": "## 簡介\n\n無線網橋就像一條看不見的網線，把現有網路連接到另一個地方；它不會憑空產生網際網路。例如，住宅和遠處倉庫各裝一台支援橋接的設備，倉庫端可以接上攝影機、交換器或無線基地台。\n\n## 工作方式與用途\n\n常見的點對點方案在兩端各有一台設備；部分產品也支援一點對多點。它常用於連接建築、農場或停車場的監視攝影機，以及其他不便布線的位置。實際距離取決於設備、環境和安裝條件。\n\n## 安裝注意事項\n\n盡量讓兩端保持通視；建築、樹木和地形可能影響訊號，而看得到對端不保證鏈路良好。依距離、頻寬、供電和防水需求選型，標稱距離和速率並非保證。使用強密碼和支援的安全功能、更新韌體，並遵守當地無線電與安裝規定。\n\n路由器主要連接和管理不同網路，無線基地台主要服務附近終端，而網橋側重連接不同位置；同一設備可能具有多種功能。\n\n## 發展與現況\n\n無線網橋隨 IEEE 802.11 無線區域網技術及室外定向天線發展；5 GHz 802.11ac 與 60 GHz 設備適用於不同場景，部分 60 GHz 設備提供 5 GHz 備援。不同廠商的橋接協定不一定相容。[^source_ieee80211][^source_mikrotik_cube]\n\nTP-Link CPE710 在 80 MHz 下的最高 867 Mbps 是無線實體層速率，不是實際下載速度；Ubiquiti Wave Nano 標示的 2 Gbps 是系統總吞吐量，不保證單向或全天候效能。距離、遮擋、干擾、負載和網路埠皆會影響結果，60 GHz 也需考慮雨衰。[^source_tplink_cpe710][^source_ui_wave][^source_itu_rain]\n\n延遲應測量空閒和滿載狀態；ping 是往返時間，並要觀察抖動、丟包和中斷。可用 iperf3 測單向與雙向吞吐量，跨日及雨天持續觀察。99.9% 年可用率約允許 8 小時 46 分鐘中斷，僅為換算例子，不是產品承諾。\n\nTP-Link、Ubiquiti 和 MikroTik 均有相關產品；截至 2026 年 10 月，尚無本詞條可核實且涵蓋全球的可比廠商市占資料，不能用 Wi-Fi 路由器或局部樣本數據代替。[^source_mikrotik_cube]",
