2. GENERAL PRODUCT DESCRIPTION
Overview
The aim of this document is to present possible and recommended hardware solutions
useful for developing a product with the Telit LM940 Mini PCIe module.
LM940 is Telit’s platform for Mini PCIe module for applications, such as M2M applications,
industrial mobile router and table PC, based on the following technologies:
LTE / WCDMA networks for data communication
Designed for industrial grade quality
In its most basic use case, LM940 can be applied as a wireless communication front-end
for mobile router products, offering mobile communication features to an external host
CPU through its rich interfaces.
LM940 can further support customer software applications and security features. LM940
provides a software application development environment with sufficient system resources
for creating rich on-board applications. Thanks to a dedicated application processor and
embedded security resources, product developers and manufacturers can create products
that guarantee fraud prevention and tamper evidence without extra effort for additional
security precautions.
LM940 is available in hardware variants as listed in Applicability Table
The designated RF band sets per each variant are detailed in Section 2.2, Product
Variants and Frequency Bands.
