In the coming weeks, I’ll be reviewing and adding support for the Airgain NL-SW-LTE-TG1WWG modem to Simple IoT for several customer applications.
This modem uses a Telit modem. Previously, we used the NL-SW-LTE-QBG96 which is based on a Quectel modem.
Airgain modems are end-device certified, which means you don’t need to get them certified by the cellular carriers to use them. Generally, we recommend you use these types of modems for low/moderate production volumes, and then if you reach high volume usage, use a solder-down module from Telit/Quectel and go through the certification process.
Below is a photo of a development kit from Symmetry Electronics.
The NL-SWDK2 development kit provides several ways to interface with the modem. From the product brief:
Developers can connect to the modem in any of three ways:
• Directly from PC to the modem’s UART port, sending AT
commands through PC terminal application
• From a microcontroller development kit that supports an
Arduino shield interface
• Through the two modem breakout headers connected to the
Skywire interface
The modem contains UFL connectors for cellular (top) and GPS (bottom) antennas.
