AP 315's Max Speed

    Hi ,

    The majority of the AP's we are currently running are the 315's and I noticed today that the Max Speed users are getting on 5 GHz is 400 Mbps. The documentation for the 315's states I should be getting up to 1,733 Mbps. Is there something I have configured wrong? We run Microsoft Surface Laptops for the most part with IT using Dell's. It's the same across the board though. 

    Thanks,

    Brandon

    You may be seeing the speed reported for a 2 spatial stream device on a 40mhz wide channel. The "marketing speed" is a theoretical maximum. You never really see speeds like that out on the real world. See this chart for expected speed with certain combinations of RSSI/SNR (Will dictate the modulation and coding), Channel Width, and Spatial Streams: https://mcsindex.com/

    So this is normal to see regardless of the AP type?

    Yes this would be a clients max speed capable on a 2 spatial stream device using a 40mhz channel with an MCS of 9. Client capabilities are shared with the Aruba APs and this is how the system calculates that value.

    FYI also you would need to get the same MCS on 2spatial streams with a 160mhz wide channel to get to the 1.7 Gbps

    Interesting, my you provide one table for AX as well ?

    Here you can find the full MCS Index table.
