Error Vector Magnitude (EVM) is a single most important performance metric of Wi-Fi systems, which gives a comprehensive indication of the quality of the Wi-Fi hardware. The transmitter chain silicon design; RF Front End(RFFE) components (filters, power amplifiers, matching and diplexers) and antennas, all add noise to the Wi-Fi system. Measuring EVM will tell you…

In my last blog, we talked about the throughput gains due to efficiency improvements in PHY layer of Wi-Fi6. I wanted to follow up with some discussions on hardware challenges and practical benefits of 1024 QAM (aka MCS 11) in this blog, but I think it is good to discuss the impact of Wi-Fi MAC…

The Wi-Fi alliance started the Wi-Fi6 certification program in late 2018. Wi-Fi6 is based on IEEE’s 802.11ax standard which has introduced many PHY and MAC level efficiency improvements such as 1/4 Sub-carrier spacing 1024 QAM (MCS 11) Upto 8 spatial Streams OFDMA (Downlink and Uplink) MU-MIMO (Downlink and Uplink) BSS coloring Target Wake-up Time In…
