一旦滿足基本規(guī)范，對RFID產(chǎn)品的性能進行優(yōu)化以贏得某一特定市場空間的競爭優(yōu)勢就顯得尤為重要。性能指標(biāo)包括標(biāo)簽的讀取速度、標(biāo)簽在多閱讀器環(huán)境中的工作能力和標(biāo)簽與閱讀器之間的距離。在消費應(yīng)用中，標(biāo)簽與閱讀器之間的通信速度直接影響用戶的滿意度。例如，使用RFID的公共運輸業(yè)，讀取時間由5秒鐘降低到小于半秒鐘后，才得到廣泛認可。在工業(yè)應(yīng)用中，速度就意味著生產(chǎn)量：生產(chǎn)量越高，資金和人力資源的使用效率就越高。由于無源標(biāo)簽從RFID閱讀器獲得它們正常工作所需的能量，多個閱讀器可能導(dǎo)致標(biāo)簽試圖對詢問它的每一個閱讀器都進行響應(yīng)。在多閱讀器情況下，為改善系統(tǒng)的吞吐量需要使用某種防沖突協(xié)議。最后，為最大化標(biāo)簽的讀取范圍，載波對噪聲(carriertonoise)的要求應(yīng)當(dāng)最小化，但是這可能與通過最小化載波的不工作時間以防止標(biāo)簽耗盡能量的需要相沖突。這些優(yōu)化措施對工程師和測量設(shè)備提出了挑戰(zhàn)。
讓我們看一個具體的例子——優(yōu)化通信速度，也稱為翻轉(zhuǎn)時間TAT(以下簡稱TAT)�？捎玫腞F能量、路徑衰落和經(jīng)過更改的符號速率能延長標(biāo)簽對閱讀器查詢的響應(yīng)時間。響應(yīng)越慢，讀取多個標(biāo)簽所花費的時間就越長。快速測量TAT對優(yōu)化RFID系統(tǒng)的速度是非常必要的。
