While I understand the meaning of RSSI in the WiFi world, I am curious if a LOW (i.e. -60 DBm) means a better signal being received from the DMR repeater I am connect to, or is a -106 DBm a better signal.
While I think this might sound like a remedial question, I am trying to get clarification.
Appreciate any information you can provide
The first reply:
LOWER IS BETTER
And the light clicks on
-106 is lower than -60. Are you guys sure you’re explaining yourselves well?
Such is just basic number theory.
(Negative numbers) Weaker signal <- 0dBm -> Stronger signal (Positive)
The 0dBm point is the reference – one milliwatt. Numbers below or above are that many dB above or below one milliwatt. In the case of receivers, the signal strength is usually very well below one milliwatt. In the case of transmitter output power, it is often above. In either case a higher number is a better receive signal, and -60 is higher than -106.
It always just bothers me when I see this as someone who thinks a growing absolute value of a negative number in this field will be chasing their tail FOREVER trying to figure out reception problems. 😉
I was searching for a previous post and found that some of the earliest posts on this blog had shit links stuffed in them for sports jerseys. This was about at the same time when I had that one post get defaced…
The content isn’t lost but I’ll have to roll it back manually.
I know what posts were affected too now, since each edit somehow generated a nonsense comment email.
I always loved that Eye On Miami never seemed to forget that we have a little traffic problem down here and that our leaders needed to be reminded about it and reminded to please act in the public interest….
But then this horrible orange thing happened and they got distracted by that and we don’t have our trains yet…
Aaaaand tonight, this happened.
This is the fastest route home that Waze could give me.
The beginning is in North Bay Village. The end is in Hallandale. They are about 15 miles apart.
Unfortunately there were simply no usable routes remaining and the first thing it found was US 41, State Road 29, and Alligator Alley.
Hey, at least I got to see two panthers at one point while going through Big Cypress….
