From a UE (user equipment, so a handset/module) perspective there are a number of parameters that are critical to its operation. This video explains what these numbers are, where they come from and how they are used. It is applicable to all UE's on the market.

This video shows how to use AT commands to create a raw TCP session from an HL78 module UART/USB interface through to a server with an open port/public IP address. The same commands are employed across the HL and RC families of products.

This video walkthrough demonstrates how to retrieve NMEA frames from modules like the EM/MC74. All required AT commands are reviewed and demonstrated.

This video shows how to start a data session that a Linux system is able to use for data communications over its USB link when connected to a 3G or LTE network.

The Qualcomm based modules may be upgraded and downgraded between firmware versions and across carrier configuration files. This video walks through how to perform this operation using the QMI SDK on an EM7565. It is applicable to all of our EM, MC, RC and WP families of units.

In embedded designs CMUX is a popular mechanism to use where an external PPP dial-up connection is used rather than the onboard IP stack. This allows the application firmware to have the connection up while still performing other operations on the unit such as querying network status, etc. This video walks through the tools that can be used on a Linux system to start CMUX, and its operation.

Within mobile networks there are different ways of being attached to a 3GPP PLMN (public land mobile network). This video explains the different types of attach statuses and how they can affect and influence data connections you are using.

When using the HL78 module, for network or application problems it may be necessary to be view the internal operation of the unit. To do this logging from its debug port is required. This video shows how to carry out this logging, resulting in a file that can be sent back to Sierra Wireless for analysis.

Several of the Qualcomm based modules that Sierra Wireless produce have the ability to store multiple firmware and carrier (i.e. Vodafone, Verizon, Docomo, etc.) configuration files. This video shows how to manage and switch between these firmware and carrier configuration files.

In some applications, the ability to know the location of the unit without powering up a GPS is useful. Using the method shown in this video, an application can perform a geolocation operation through the use of a pure cell ID. This is demonstrated using the WP7607, which is a 2G/3G/4G module. However, any module can be used.
