Operation Guide for LNADVW Module
1. Product Overview
LNADVW 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). LNADVW also
supports WiFi and will be used provide WiFi Hotspot functionality within the vehicle.

3. Device Installation and User Manual
The LNADVW 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 LNADVW 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 LNADVW module and RF Connector:
- Recommended RF Connector Type: Fakra
- 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 and IC requirements for the integrated
