無線網橋的架設方式主要有四種,分別是點對點、點對多點、中繼以及發射,而這四種方式適合的場合都不一樣,下面我們一起來看看。
點對點傳輸:也就是常說的PTP,是最簡單的傳輸模式。由於點對點傳輸的損耗較少,所以傳輸距離也相對較長,因此2.4G和5.8G的無線網橋都適用。
點對多點傳輸:基於點對點傳輸模式發展,點對多點傳輸是多個發射點與接收端之間的傳輸,所以角度要合理,同時損耗較大,適合傳輸距離較近,因此,僅適用於5.8G的無線網橋。
無線中繼:在WDS上可以讓無線AP之間通過無線信號進行橋接中繼,無線中繼模式雖然使無線覆蓋變得更容易和靈活,一旦AP出現故障,整個WLAN將癱瘓。因此,無線中繼模式僅適用於沒法進行網絡布線的特殊情況下,以及那些場地開闊、不便於鋪設以太網線的場所。
反射傳輸:反射傳輸是藉助了傳輸設備之外的物體進行微波發射傳輸,這樣可以通過調整設備的角度,通過建築物或山峰反射微波信號進行無線通信。

Wireless bridge installation method
Peer-to-peer transmission: also known as PTP, is the simplest transmission mode. Since the loss of point-to-point transmission is small, the transmission distance is relatively long, so both 2.4G and 5.8G wireless bridges are applicable.
Point-to-multipoint transmission: based on the development of point-to-point transmission mode, point-to-multipoint transmission is the transmission between multiple transmission points and receivers, so the angle should be reasonable, and the loss is large, suitable for transmission distance, so only applicable. Wireless bridge at 5.8G.
Wireless relay: On the WDS, wireless APs can be bridged and relayed by wireless signals. Although the wireless relay mode makes wireless coverage easier and more flexible, once the AP fails, the entire WLAN will be paralyzed. Therefore, the wireless relay mode is only suitable for special cases where network cabling is not possible, and where the venue is wide and it is not convenient to lay Ethernet cables.
Reflective transmission: The reflection transmission is carried out by means of an object other than the transmission device for microwave transmission, so that the microwave signal can be transmitted through the building or mountain reflection microwave signal by adjusting the angle of the device.
