Operation Guide for CUW Module

1. Product Overview

CUW wireless module is a proprietary modem designed and manufactured by Continental Automotive Systems, Inc. The modem will be integrated into Data Connectivity Modules (DCMs) designed and produced by Continental for use by automotive OEMs. DCMs will be

installed into vehicles during the OEM’s factory assembly process and will not be accessible

without use of special tools. Primary use-cases are data-centric with data and voice connections to Telematics Service Providers (TSP). CUW also supports WiFi and will be used provide WiFi Hotspot functionality within the vehicle.

2. Regulatory Compliance Notes

FCC:

This device complies with Part 24(E) of the FCC Rules. The FCC ID for this device is LHJCUW. Operation is subject to the following two conditions:

1. This device may not cause harmful interference.

2. This device must accept any interference received, including interference that may cause undesired operation.

3. Device Installation and User Manual

The CUW module is a proprietary product designed and manufactured by Continental Automotive Systems, Inc. for integration into telematics control units manufactured by Continental Automotive Systems, Inc. for automotive OEMs.

i. The module is limited to installation ONLY in an integrated device manufactured by

Continental Automotive Systems, Inc.

ii. During manufacturing process of the integrated device, the module is soldered onto the

pcb of the integrated device.

iii. The integrated device must provide RF connectors to external antennas or RF traces to

connect the CUW modules to antennas inside the integrated device.

The typical reference design for the trace layout, including pcb stack-up and trace length is as described and shown in a Figure 3 below:
