Wireless connections have improved a lot lately and the data-rates and latencies that are now achievable with LTE make mobile broadband connections a key ingredient in every M2M recipe. But LTE mobile broadband connections in Linux-based systems are no longer setup using the good old AT+PPP pair. LTE-capable modems now use ECM-like network interfaces and even new control protocols, like QMI or MBIM.
This talk is about how the new LTE-capable devices are exposed in the Linux kernel (e.g. qmi_wwan, cdc-mbim...), and which user-space tools (e.g. ModemManager, libqmi, libmbim...) are available to control them. The talk will be a hands-on demonstration of how to use these modems with these tools, focused on what users need to do to use them properly, and also how developers can benefit from them to write new applications.
