Wi-Fi 7, based on features defined in the IEEE P802.11 be draft amendment. Wi-Fi 7 enables significantly faster speeds by packing more data into each transmission. 320 MHz channels are twice the size of previous Wi-Fi generations. 4K QAM (Quadrature Amplitude Modulation) enables each signal to more densely embed greater amounts of data compared to the 1K QAM with Wi-Fi 6/6E, which – to continue the truck analogy– is like having professional movers optimize truck cargo space to pack the maximum number of boxes.

How to address this Wi-Fi 7 320MHz channels band width and 4K QAM modulation / demodulation test challenges. Teradyne have LitePoint box solution and also new generation RF instrument – UltraWave 8G based on UltraFlexPlus Platform.

We had setup experiment with LitePoint box and UW8G for investigation. In this paper, we will compare test solution RF performance on EVM, ACLR etc, and also programming model and test time. It will help us understand advantage and disadvantage of each solution.
