User’s Guide and Test Manual for LTE Modem

(Type Approval Model: LNAD)

1. Product Overview

LNAD wireless modem 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).

High-level List of features

• Supported Protocols and Bands

o LTE band 4 (DL: 2110-2155 MHz, UL 1710-1755 MHz).
o LTE band 17 (DL: 734-746 MHz, UL: 704-716 MHz)
o LTE band 2 (1900 MHz)
o LTE band 5 (850 MHz)
o 5MHz and 10 MHz bandwidths supported for all LTE bands
o UMTS bands: II and V
o GSM operation not supported

• Binary SMS

• AGPS – not supported

• 911 and personal calls will not be placed (blocked by DCM, the telematics host)

• Solderable surface mount design for integration into DCM design

• WiFi circuit is populated but not powered or used.

The LNAD module is a proprietary product designed and manufactured by Continental Automotive Systems, Inc.
The module will be integrated into telecommunication control devices produced by Continental for its automotive
customers. Because LNAD is not intended for sale as a stand-alone device or offered for sale to general public, the
user’s manual and sales brochure are not applicable to this product.

LNAD is a surface mount (SMT) module with 122 solderable connection pads. The module is LGA package type
with dimensions 35x40x3.5mm. Two-piece shield provides RF protection.

2. FCC Note

This device complies with Parts 22, 24, and 27 of the FCC Rules. The FCC ID for this device is LHJ-LNAD. The
device meets the mobile RF exposure limit at a 20 cm separation disctance as specified in §2.1091 of the FCC Rules
and Regulations and Health Canada Safety Code 6.

Operation is subject to the following conditions:

The device 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.
For mobile and fixed operation configurations the antenna gain, including cable loss, must not exceed the
limits listed in the table below:

Changes or modifications to this system by other than an authorized service facility could void authorization to use
this equipment.

If LNAD module is incorporated into mobile or fixed host devices, the host devices may use the FCC Grants of the
LNAD modules for the final product if they meet conditions listed above. The label of the host product shall be
clearly visible from the outside and include text “Contains FCC ID: LHJLNAD”. The integration is limited to host
devices where there is at least 20 cm separation between antenna and a person.
