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 LE910Cx-mPCIe module. LE910Cx-mPCIe is Telit platform for Mini PCIe 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, LE910Cx-mPCIe 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. LE910Cx-mPCIe can further support customer software applications and security features. LE910Cx-mPCIe 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. LE910Cx-mPCIe is available in hardware and band variants as listed in 2.2 Product Variants and Frequency Bands.

Temperature range

Case

Range

Note

Operating Temperature Range

–20°C ÷ +55°C

The module is fully functional(*) in all the temperature range, and it fully meets the 3GPP specifications.

–40°C ÷ +85°C

The module is fully functional (*) in all the temperature range.

However, there may be some performance deviations in this extended range relative to 3GPP requirements, which means that some RF parameters may deviate from the 3GPP specification in the order of a few dB. For example: receiver sensitivity or maximum output power may be slightly degraded

Storage and nonoperating Temperature Range

–40°C ÷ +105°C

Table 5 Temperature range

(*) Functional: the module is able to make and receive calls, data connection and SMS.
