Question: LTE Active user and Latency

[b0r3l_1]

Hi Guys,

Need your expertise, what is the correlation of LTE active user and latency? We are having high latency (70 - 150ms) during peak periods. I'm using ping tool from google play and directly pinging the router (Ookla server) before going to the internet. I believe the LTE scheduling plays a part here since during peak period our simultaneous users reach around 50 -90. Thanks

There's probably packets dropping somewhere. Number of users should not impact latency. Check SCTP retransmission counter if you suspect backhaul (S1) problem, check UGW, LAN switch, firewall interfaces for packet drops otherwise.

Here's the sample ping captured

Hi

Have you verified through TWAMP?

It depends on the Cell BW (10Mhz, 20Mhz, etc) and the scheduling algorithm.
