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.

exceptions listed below.
[2] Not supported AT commands:
* $ARME and $ARMEE: related to RPM configuration
* +CTSA and +CBKLT: used for emulating touchscreen action and turning on/off the display backlight.
Probably not applicable for embedded module.
* +CESP: used for SMS block mode protocol
[3] AT Commands with limited support:
* +PACSP: appears to only work when camped on 3G network (e.g., UMTS)
* +++ packet data escape sequence may only be supported for UMTS circuit switched data.
5. Appendix 1: Windows 7 USB driver installation issue and solution
Device Manager displays many 'Unknown device' entries referencing mfe_firehkmp in the Network adapters
section
5.1
Environment
McAfee Host Intrusion Prevention 7.0
Microsoft Windows 7
5.2
Problem
Multiple Unknown device entries are listed in the Network Adapters section of the Device
Manager. Each of these entries reference mfe_firehkmp.
An affected system may also be unable to use a VPN Client or install any software that uses NDIS
5.x drivers because no additional NetLuids can be enumerated.
User’s Guide for LNAD
(FCC ID: LHJ-LNAD)
Rev: 0.7
Page 8 of 8
5.3
Cause
The Host Intrusion Prevention (Host IPS) 7.0 NDIS 5.x driver does not correctly remove and clean
up NetLuid on systems running Microsoft Windows 7. Over time, this causes all NetLuids to be
exhausted.
5.4
Solution
Use the following steps to fix this issue.
5.4.1
Open an Administrative command prompt.
5.4.2
Run the NDISCleanup utility for your specific system (x86 or x64) using the following
command:
ndiscleanup -cleanup -if 1
5.4.3
Run regedit the following way,
psexec -i -d -s c:\windows\regedit.exe
5.4.4
Navigate
to
the
following
key
and
delete
it
if
it
exists:
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\Root\MFE_FIREH
KMP]
5.4.5
Restart the system.
