Arista Wi-Fi 7 AP (C460) Launch & Early Experiments and Field Trials on Wi-Fi 7 Client Behavior

Multi Link Operation (MLO) is touted as one of the biggest technical benefits of Wi-Fi 7. In this session, we will share some insights into the MLO (Multi Link Operation) behavior of popular Wi-Fi 7 clients in different configurations, with real demo. Specifically, we will show the behavior of client with respect to STR MLMR and EMLSR.
We will also show Preamble Puncturing in action, which is especially useful when operating in wider channel width.

Hi, Does the STR-supported S24 Ultra phone have 2 radios and 2 antennas? When operating in STR Mode, are the antennas configured as 1x1 for the 2.4GHz band and 1x1 for the 5GHz band to communicate with the AP via MLO?

If the S24 Ultra has a total of 2 antennas, wouldn't EMLSR mode achieve higher efficiency performance compared to STR mode? This is because EMLSR can utilize all NSS for transmission using the link with the same wireless communication.

What I'm curious about is the power consumption of clients in the real world, where they will generally support EMLSR. However, I observed in packet sniffing that the S24 Ultra has STR capability during the connection phase. I found this very interesting. How many antennas does it have for each independent radio? This STR feature can cause significant battery consumption. Unfortunately, detailed WiFi chip and hardware specifications for clients are not mentioned.

Nice demos, in particular preamble puncturing.
