Technical specs regarding PCIe vs USB 3.1


Are there any technical specs published by Sierra Wireless regarding the differences between using the PCIe physical connection versus using USB 3.1? E.g. differences in max throughput, latency and so on applicable specifically to the EM91x or EM92x modules.


Hi @aleksander0m,

There is no official Throughput information for the mentioned EM9 modules. In this case, it’s best to email technical support at for assistance.
