As IEEE 802.11 is the preferred radio technology, IEEE 802.11 task group TGba focuses on the IEEE 802.11-based WuR standardization. We present an implementation of a wake-up receiver (WuRx), based on off-the-shelf components, using a microcontroller unit for decodification at the fastest bit rate of 250 kb/s allowed by TGba. The proof-of-concept that has been developed, does not aim at presenting an optimized power consumption solution for WuRx, but at enabling a comparative evaluation for several reception cases based on latency and power utilization. The evaluation of the performance shows the WuRx robustness in presence of frame receptions different from the expected for WuR operation or addressed to other WuRx in the surrounding area. This letter also presents the convenience of implementing a mechanism for avoiding consecutive erroneous WuRx identification matchings within the same WuR procedure
