IP performance parameters analysis. (a) Instant IP bandwidth measurements during 10 VoIP calls in an EPA5 LTE scenario with a 7 dB of SNR. (b) Packet losses per VoIP call for different levels of SNR in an EPA5 scenario. (c) Instant jitter measurements during 10 VoIP calls in a EPA5 LTE scenario with a 7 dB of SNR. (d) Mean Jitter per VoIP call for different levels of SNR.
