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 LHJ-
CUW. 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:
Typical RF trace layout between the CUW module and RF Connector:
- Recommended RF Connector Type: Fakra
FCC ID: LHJ-CUW
- Main LTE/WCDMA antenna connector (MIMO1) is X203.
o Recommended RF trace length is less than 40 mm.
- Diversity LTE/WCDMA antenna connector (MIMO2) is X202.
o Recommended RF trace length is less than 45 mm.
- WiFi antenna connector is X201.
o Recommended RF trace length is less than 50 mm.

iv. Automotive OEM is responsible for ensuring that the end-user has no manual instructions
to remove or install module.
v. The module is limited to installation in mobile applications, according to Part 2.1091(b).
vi. No other operation configurations are allowed.
vii. Changes or modifications to this system by other than a facility authorized by
Continental could void authorization to use this equipment.
viii. The module must be installed to provide a separation distance of at least 20 cm from all
persons and must not be co-located or operate in conjunction with any other antenna or
transmitter.
ix. The integrator is responsible for fulfilling FCC requirements for the integrated device.
If Continental chooses to re-use modular approval, then the TCU shall be clearly labeled with
an external label containing the integrated modem’s FCC ID. For example, the label can
include text “Contains device with FCC ID: LHJ-CUW.
4. Antenna requirements for use with CUW module:
·The module must be installed to provide a separation distance of at least 20cm from all
persons and must not be co-located or operating in conjunction with any other antenna or
transmitter.
· The CUW module is for use with external antennas ONLY.
· For all LTE operating bands the maximum antenna gain is 6 dBi including cable loss.
· The maximum gain of the antenna path (cable loss + antenna gain) shall not exceed the
above mentioned values.
This radio transmitter (FCC ID: LHJ-CUW) has been approved by FCC to operate with the
antenna types listed below with the maximum permissible gain indicated. Antenna types not
included in this list, having a gain greater than the maximum gain indicated for that type, are
strictly prohibited for use with this device.
5. Instructions to OEMs:
Continental must instruct the automotive OEM and provide them to include the following
information into the car user’s manual (i.e. for the DCM):
1. End-users must be provided with transmitter/antenna installation requirements and
operating conditions for satisfying RF exposure compliance:
2. A separate section should clearly state “FCC RF Exposure requirements:”
3. Required operating conditions for end users.
FCC ID: LHJ-CUW
4. The antenna used with this device must be installed to provide a separation distance of at
least 20cm from all persons, and must not transmit simultaneously with any other
transmitter, except in accordance with FCC multi-transmitter product procedures.
5. The Maximum ERP/EIRP and maximum antenna gain required for compliance with Part
24(E).
6. Clear instructions describing the other party’s responsibility to obtain station licensing.
