Can we get complete information on the transmit power and receive sensitivity for recent radios? I’m particularly interested in the NetMetal5 SHP.
Spec sheets on the web site look like they provide this information at first glance, but only a subset (and an obfuscated subset at that, I believe).
e.g. if you look here : https://mikrotik.com/product/RB921UAGS-5SHPacD-NM it lists tx power and receive sensitivity for “MCS0, 7, 9” but does not state for which channel widths these figures pertain. According to Wikipedia : https://en.wikipedia.org/wiki/IEEE_802.11ac, some MCSx does not define the channel width. e.g. MCS5 pertains to 20, 40 and 80MHz channel width. Presumably tx power is reduced for wider channels. Also MCSs 1,2,3,4,5,8 are omitted. The live radio is no help here as it will not disclose its tx power. Rx sensitivity can somewhat be deduced by experiment – watching rssi and correlating with the chosen data rate, then varying tx power on the transmitter. This is however a very time consuming and error prone way to determine sensitivity.
I’d like to perform an accurate link analysis but without this data the task is not possible. Thanks.
