LE910-EUv2: LTE Data Connection Speed Benchmarking

3 thoughts on “LE910-EUv2: LTE Data Connection Speed Benchmarking

  1. Hello,

    I’m doing data transfer speed measurements/benchmarking with different modems and LE910-v2 is one of those that I’m doing measurements on.  The host board is a ARM-based platform running embedded Linux and the modem connects to it via USB.  At the moment I’m using Speedtest.com to measure LTE data connection speeds using a common SIM card with different modems.  The TELIT LE910v2  (S/W ver) 20.00.402 that I’m using gives me slower speed readings compared to another modem (different maker) and I’m sure this is probably because I may have been missing out on some settings either in the modem settings itself or on the host Linux stack.

    1.  Do you have any recommendations on how to best measure LTE connection speeds (without the need of very expensive/specialized LTE equipment)?

    2.  TELIT LE910v2 uses USB-NCM connections to the host (the other modem I tried used USB-ECM), are there any settings in the modem that can be tweaked for doing optimizations?

    Thank you very much.

    1. 1.  Do you have any recommendations on how to best measure LTE connection speeds (without the need of very expensive/specialized LTE equipment)?

      First of all be sure you are comparing the modems when registered to the same network and possibly same channel and signal quality.

      You can use AT+COPS?, AT#MONI, for this. Have the modems you are testing the same LTE category?

      Both NCM or MBIM interfaces are fine to test high throughputs. Usually it is recommended to use for data connection a PDP context different from 1, which is normally used by the network of IMS and EPS registration.

      1. Thank you very much, Andrea.  

        I will try what you’ve advised and post any new findings here.
