歐洲電信標準協會(European Telecommunications Standards Institute,簡稱ETSI)在2012年6月4日發布了ETSI EN 300 328 V1.8.1正式版本, 由於上一版本是在2006年發布的, 因此最新版本和前一版本有許多差異, 強制實施日期為2014年12月31日

由於一般使用者在使用2.4GHz產品時, 容易被其他同頻段的產品干擾, 因此在最新版本中, 特別提出adaptive equipment, 而adaptive mode在1.8.1版法規中的定義如下:

adaptive mode: mechanism by which equipment can adapt to its environment by identifying other transmissions present in the band

在1.8.1版本中新增了一些測試項目, 分別針對adaptive equipment和non-adaptive equipment新增的測試項目, 其中有Medium Utilisation (MU) factor, Adaptivity, Receiver Blocking, 這些都是前一版本沒有的測項;

此外, 舊版中Frequency range的測試項目1.8.1版本中被替換成99% Occupied Channel Bandwidth, 並且EN 300 328 V1.7.1
