I'm trying to compare two antennas, A and B for WiFi.
A is showing:
Signal Strength of -77dBm, but
SNR of 9dB.
B is showing:
Signal Strength of -85dBm, but
SNR of 24dB.
My understanding is as follows - but I'm no expert on the matter: Better signal means I'll be able to receive data further away from the source, but better SNR means that signal will have a higher throughput (because less packets are being corrupted).
Does this make sense? And is there some equation to use both of these measures to form a single comparable number for digital throughput?
