Wireless Signal strength.

Folks,

What does the db strength mean for the wireless signal. Is a -70dB considered good?

Hi Nik,

You need to check Noise level as well (or SNR), if you have RF environment where SNR is greater than 25 then that is good for sensitive applications running on wireless(like voice).

In a typical environment Noice level is consider as -92dBm, so to have 25SNR you should have signal strength (or RSSI) -67dBm or better. That's why for voice application we are trying to give -67dBm or better.

On the other hand data applications would work even with -75dBm signal as well.
