It looked better when the 
was white on red (it’s showing green in the Windows session I’m using now because of the changes Discourse made to their emoji set use) and provided better contrast to 
, and I probably could’ve highlighted the “5 GHz” vs “5G” thing better rather than sticking it in a footnote. I s’pose I could redo the table with 
and 
or 
. 
Note that frequencies are expressed in GHz, which is gigahertz, and that this is not the same as the “G” used in wireless communications labels like “5G” where the “G” stands for “generation”. ↩︎
