Hi guys!

I would like to know, is there any command to get information about Resource Blocks and Modulation Coding Scheme ?

Thanks.

http://rfmw.em.keysight.com/wireless/helpfiles/89600b/webhelp/subsystems/lte/content/lte_overview.htm as first of google result and many at commands give RB as
100 → like 100% of 20Mhz bandwith
50 → like 50% of 20 means 20/2=10Mhz
etc.
And you can check cellular tab or info command to see that bandwith.

and Modulation Coding Scheme ?

You know that lte6 is lte category below cat.12 because 6 is smaller then 12 :slight_smile: http://anisimoff.org/eng/lte_mcs.html
And this means max modulation can be 64qam… and final was is to know the CQI who is show at the same place what prev. parameter.

Thanks! It’s very helpfull.

I haven’t tried rb commands yet, but my CQI is never lower than 12 and sinr is 20+

What is a real world maximum speed with b7+b7 on r11e?
Can I get closer to it’s 300 mbit/s with hex s USB?

I don’t need this max in reality, just want to play with and get as much as possible, this why I can change cells and locations for testing.

very promissing


What is a real world maximum speed with b7+b7 on r11e?

max I see was 195Mbps but this was at SXTR with bonding 2xFE, without 1GbE port who will show us more speed from r11e-LTE6.
For now, no one not show max speed. Not every country have B7+7 at one ISP and both as 20Mhz bandwitch and not load Tower/Bts/eNB by other users.

But what you will connect to that USB?

145 Mbps is my max for now and 100-110 Mbps as average.
I`v seen 300+ with current provider on Android, it was B7+B7 and this cell is not far away from my house.


But what you will connect to that USB?

USB 2.0 to Mini pci-e card. I think that can be a bottle neck but not sure about r11e-lte6 uses USB 3.0 in pci-e form factor.
Plus I want to add some cooling because it works with 2x -17db Yagi.
