Bosch Km 1100-T 048798-401 工業WLAN比一般企業辦公和家庭應用環境用的WLAN要求要高許多，可歸納如下：
（1）嚴格的延遲要求：用于現場設備要求延遲不大于10ms，用于運動控制不大于1ms，對于周期性的控制通信，使延遲時間的波動減
至最小也是很重要的指標。
（2） 確定性性能的保證：保證確定性是對任務執行有嚴格保證的工業通信系統必備的特性。即使設備處于漫游狀態也有此要求，否則會喪失實時性能。
（3）支持大量設備掛網，并容許掛網設備的接入數量可隨機變化：工業WLAN的接入點約為數百個的數量級。若節點過多和接入的節點數有變化，有可能導致IEEE 802.11的MAC協議層效率太低。
（4）網絡安全的保證：滿足安全保密法規是工業WLAN的基本要求。包括防止黑客用戶的侵入及對這些接入點的檢測等。
（5）網絡投用的保證：由于運行故障是不可接受的，因此對于有幾百個設備節點的WLAN來講，要求網絡具有自投用功能，并能執行無線配置和輔助節點位置的自動搜索。
IEEE 802.11在技術上并不能提供確定性的保證，但在802.11e 中給出了在MAC層支持多傳輸介質應用及保證通信質量QoS的擴展。一方面解決了在MAC層的優先級服務，另方面又通過輪詢規約（polling protocol）實現多介質的通信調度。由于輪詢在本質上具有確定性，因而可以避免由802.11的信道爭用和指數補償而造成的延遲。為了防止輪詢可能帶來的不良問題（如在需要發送的數據尚未形成之前輪詢信號已到，那么該數據的發送則不得不再等待一個輪詢周期），需要通過自適應輪詢算法保證現場設備同步。
由此可見，雖然工業WLAN的市場容量相對較小，但性能要求卻很高。工業WLAN的產品應靈活地通過軟件模塊實現802.11的分標準。如Siemens已問世的產品SCALANCE-W，就可提供工業QoS和快速漫游的解決方案。
無線信息傳輸主干網
由于ZigBee是短程網，不可能覆蓋整個廠區，加之原有的現場總線也很有效，所以設計了一種無線信息主干網系統。通過建立發射功率較大的無線信息主干網（WIB，Wireless Information Backbones），可將ZigBee傳感器的信息傳輸給各種掛在以太網、現場總線上的物理設備（如圖3）。WIB的節點一方面是無線網絡上的一個節點，另一方面又起著無線通信協議和其他有線通信協議的轉換作用。實踐證明，采用1W的發射功率，WIB就可穿透多數的工廠和成套設備。這樣，ZigBee因其發射功率小、易受鋼結構所衰減、傳輸距離短等固有問題，完全可以通過WIB予以解決（參見圖4和圖5）。而其低功耗、低成本、傳輸可靠性高、簡便實用等優越性又可以充分被利用。
