TECHSHIP IS A GLOBAL SUPPLIER OF WIRELESS COMPONENTS
The Telit LM960A18 Mini PCIe (mPCIe) data card delivers high speed data rates via Advanced LTE and offers a cellular connection for products in network appliance environments. This data card is well-suited for products that demand high throughput such as routers, mobile gateways and access points, to provide the most advanced 4G LTE connectivity, ensuring a rich and seamless user experience.
Based on LTE UE category 18, the LM960A18 mPCIe data card achieves download rates up to 1.2 Gbps and upload rates of 150 Mbps.
It supports up to 5x downlink carrier aggregation and 2x uplink carrier aggregation, 2x2 MIMO (4x4 MIMO on a set of bands). Please refer to the LM960 Hardware Guide for complete specification. The product supports multiple RF frequency bands and band combinations to accommodate global deployments.

How-to change the cellular modulesUSB composition mode to Mobile Broadband Interface Model (MBIM) used by Windows 8 and 10 systems for controlling and establishing data connectivity through the built-in connection manager in Windows?
This is done by sending a set of AT commands to the cellular modules Modem or AT serial interface found in Windows Device Manager. Please see list below for associated AT commands.
(For additional details, refer to the product specific software, ports, and AT commands guides found on the Techship product web pages under technical documentation tab).
After the AT commands have been received by the module and has restarted, the USB interface endpoint composition should have changed to include MBIM interface as well.
You can find the correct Serial COM port number by checking Windows Device Manager, under the Modems drop down -> (right click and see properties for selected COM port info) or under the Ports (COM & LPT) drop down.

Telit LE910C1 and LE910C4 series:
Telit LM940 and LM940A11:
Telit LM960 and LM960A18:
Telit LE910 V2 series:
On Huawei and Telit LN94x series modules the USB mode changing is done automatically by the modules Windows drivers based on current Windows version.
Please be aware that some USB mode configurations do not include any serial interfaces, making it impossible to revert the changes using AT commands.
How can we establish data connection for cellular modules in Windows 8 and Windows 10 systems?
Microsoft Windows desktop versions starting from Windows 8 and newer have built in data connection manager for WWAN, Wifi etc. that can be used to configure, control and establish the data connection of cellular module that support MBIM interface, which most cellular modules do.
The connection managers settings and controls can be found and accessed on Windows desktop start menu through the network icon (see picture).
The Cellular tab can be found in Windows system settings and if needed the connection APN details can be manually entered through "Advanced options".
What Linux kernel modules and configs are commonly used for communicating with cellular modules over their USB interface?
Most cellular modules can be supported in Linux by using som of the in-kernel drivers. The physical data interface to the host Linux system is usually done over USB which enumerates a set of different endpoints/interfaces. A set of serial interfaces for Modem/PPP, AT commands, NMEA location data and chipset debug information are almost always available in all configurations.
In addition some type of network endpoint/interface are also available and exposed. This can vary between manufacturers and chipset vendors and can also commonly be configurable by using USB configuration mode switching or through vendor specific AT commands.
Recommended kernel configurations to enable are listed bellow. Many cellular modules base their Linux support on these modules and drivers. Once included in the kernel build, the USB interfaces will be detected and bound correctly out-of-the-box or after applying source code patches to the driver modules.
Configs for USB serial drivers:
Configs for Modem/PPP support:
Configs for USB network drivers:
Please relate to the Techship product specific web pages for vendor specific Linux integration guides.
