Which signal strength and noise values meet the minimum SNR for voice networks?
A. signal strength -69 dBm, noise 94 dBm
B. signal strength -67 dBm, noise 91 dBm
C. signal strength -68 dBm, noise 89 dBm
D. signal strength -66 dBm, noise 90 dBm
Correct Answer: B
The minimum recommended wireless signal strength for voice applications is -67 dBm and the minimum SNR is 25 dB.
