It includes lots of essential improvements (but not limited to):

• AMPDU (Aggregated MAC PDU)
• Achieve self-interference free in OTA test while achieving fast TDD turnaround time (0.6us)
• Essential improvements on RF, baseband/FPGA and driver. iperf: TCP 40~50Mbps; UDP 50Mbps (best case AMPDU on); EVM -39dB; MCS0 sensitivity -85dBm (no external LNA); MCS7 -73dBm. (Both conducted/cable and radiated/OTA test)
• More app notes about: CSI radar; Packet, IQ sample and CSI self-loopback test; CSMA and arbitrary frequency/channel setting; FPGA and driver event/packet statistics; and more.
