Estimated LTE Data Utilization in Failover Scenario

Wed Jul 31 16:54:26 UTC 2019

In my experience with LTE is that it’s never enough. We have bank branches
with 20Mbs metro lines and on rare occasion when that circuit drops 4G LTE
will provide you with 10mbs at best also note that latency is much higher
which can mess with ipsec/VOIP etc. I don’t think you can pick how much
bandwidth you will get with 4G LTE. From the testing I have done with VZ 4G
I get 10mbs down and 2/3 up with a -65 RSSI. It’s still better to have LTE
for a backup then not to have it. 

I have used cradlepoint and now switched to cisco ISR 1111. I find the
crandlepoint to be not as reliable as the cisco ISR. The cradlepoint will
get extremely hot, go down for no reason and has poor signal compared to the
ISR 1111 with LTE.  I would stay away from the cradlepoint and find a Cisco
LTE solution. 

Again like I said a backup of any kind even if not sufficient in bandwidth
is better than nothing.

Good Morning,

First time NANOG poster, apologies if I breach etiquette.

Does anyone have any first-hand data on how much data a small-medium
business (SMB) can expect to consume in a failover scenario over a 4G/LTE
connection?  Retail, under 50 head count, using PoS, maybe cloud accounting
software, general internet activity, 8 hour time period.  Wonder if anyone
is using a Cradlepoint or SD-WAN solution that could pull a few quick
numbers from a dashboard for me.  I haven’t had much luck in my searches.

Appreciate any info anyone can provide.

Thanks,
