style="text-indent:25px">BLE藍(lán)牙模塊芯片極小，可以直接嵌入數(shù)字電表中。其工作采用2400～2483.5MHz的ISM(工業(yè)、科學(xué)和醫(yī)學(xué))頻段，這是因為該頻段內(nèi)沒有其它系統(tǒng)的固定信號干擾，同時頻段向公眾開放，頻段在全球范圍內(nèi)有效。但同時ISM頻段作為開放頻段，使用其中的任何頻段都會遇到不可預(yù)測的隨機干擾源(如某些家用電器、無繩電話和汽車開門器等)。因此，對外部和其它藍(lán)牙用戶的干擾源用不同的技術(shù)加以處理。如：采用跳頻技術(shù)，抗信號衰落;采用快跳頻和短分組技術(shù)，減少同頻干擾，保證傳輸?shù)目煽啃?采用前向糾錯(FEC)編碼技術(shù)，減少遠(yuǎn)距離傳輸時的隨機噪聲影響;采用FM調(diào)制方式，降低設(shè)備的復(fù)雜性等。目前藍(lán)牙技術(shù)的傳輸速率設(shè)計為1MHz，以時分方式進行全雙工通信，其基帶協(xié)議是電路交換和分組交換的組合，完全滿足電表收費中的實時性的要求。</p><p
