The reason 6Ghz was introduced with WiFi 6E and 7 was because 2.4Ghz and 5Ghz was very busy.
My question is why isn’t there anything in between? Why isn’t there a 3Ghz, 3.5Ghz, 4Ghz, etc?
Also, what if things that require very little data transmission used something lower than 2.4Ghz for longer range? (1Ghz or something?)
shouldn’t the arrow be pointing down?
To be fair I was really lazy and just grabbed the first one I saw with “not” inserted into it.
Because yes you are correct.
Growing up I always learned (I think) the “insert missing text” symbol was shaped like the one in the pic, like a caret symbol.
The odd thing is I also remember the caret and inserted word being at the top like in OP’s image, but style guides I can find now show the caret at the bottom and the inserted text at the top.

Wikipedia seems to indicate using a downward facing caret, or a caret with an extra upward arm https://en.m.wikipedia.org/wiki/Caret_(proofreading)
TIL!
All that to say the formatting of OP’s pic, no matter the direction of the arrow/caret, makes it hard to read. A little “don’t dead open inside” or something.
Edit to add: This one shows it the way I remember it https://dmlfnsgrade9isawesome.weebly.com/editing1.html
