Testing Uplink Accuracy for WLAN IEEE 802.11ax

Wireless connectivity, which has been successfully implemented all over the world, has gone through some tremendous evolutionary steps. Legacy WLANs have introduced physical layer functionality such as wider bandwidth, MIMO and higher-order modulation schemes, achieving higher throughput. To tackle the challenges of crowded networks, the upcoming new IEEE802.11ax standard will now focus on increasing overall efficiency.

The most important change is the introduction of OFDMA for uplink and downlink, which offers more flexibility but also increases complexity. To ensure the success of future WLAN IEEE802.11ax devices and services, it is obvious that new tests must be conducted to verify interworking.
