4G/LTE eHWIC card troubleshooting

Team first of all I am not 100% sure if this belongs in this forum,

I have a 2911 with the right IoS loaded and the card is working and I can pass traffic over a major carriers Wireless private network.

My question will be very easy to most off you.

Sometimes I get complaints that the site is slow or not working well, now from a signal point of view I am looking pretty good.  I am at -70dBm range with a positive SINR (Signal to Noise Ratio)

My question is remotely and with the utilization of Pings is there any way I can calculate the data throughput?

For instance if I shared with you this info below can I do some calculations?  I have found some on the internet but I am not sure I am trusting them.

Hub Router#ping xx.yy.zz.11 repeat 1000 size 1500

Type escape sequence to abort.

Sending 1000, 1500-byte ICMP Echos toxx.yy.zz.11

, timeout is 2 seconds:

Success rate is 100 percent (1000/1000), round-trip min/avg/max = 80/81/388 ms

Any help and input provided would be great appreciated.

Thank you all so much.
