style="text-indent:25px">BLE藍牙模塊技術(shù)使用與傳統(tǒng)藍牙技術(shù)相同的自適應(yīng)跳頻(AFH)技術(shù)，因而能確保BLE藍牙模塊能夠在住宅、工業(yè)與醫(yī)療應(yīng)用中的“嘈雜”射頻環(huán)境中維持穩(wěn)定的傳輸。為了較大程度地減少使用AFH的成本與功耗，BLE藍牙模塊技術(shù)已將通道數(shù)量從傳統(tǒng)藍牙技術(shù)的79個1兆赫茲寬通道減少至40個2兆赫茲的寬通道。藍牙技術(shù)、無線LAN、IEEE802.15.4/無線個域網(wǎng)以及許多專有的無線電均使用無需認證許可的2.4千兆赫工業(yè)科學(xué)醫(yī)療（ISM）頻帶。由于共享這一無線電波空間的技術(shù)過多，因此無線性能會因干擾所引發(fā)的錯誤修正與重復(fù)傳送而下降（例如延遲時間增加和吞吐量減少等）。在要求嚴格的應(yīng)用中，可通過頻率規(guī)劃與特殊的天線設(shè)計減少干擾。鎮(zhèn)江品牌藍牙透傳模塊</p></p><br
