1.0 INTRODUCTION
The Telematics Control Unit (TCU) integrates an on-board cellular communication module with a
WiFi hotspot functionality and interacts with remote call/data centers to provide valuable services
to the vehicle customer.
1.1 PURPOSE AND SCOPE
This conditions document is to provide installation instruction to OEM to insure safe use of the
device.
1.1.1 TCU Functionality
The TCU allows customers in to connect to their car from their phone or PC to issue commands,
retrieve information, and receive alerts for important information about their car.
For FB40-ND1 customers this means the ability to remotely control charging, receive alerts about
their charging activities and warm / cool their cabin on demand.
In addition, customers can perform lock and unlock remotely, locate and track their vehicle and
receive alerts on their phone or email if the vehicle alarm is activated.
Depending upon the level of technology supported, the customer may also be able to access
services via voice or transfer data at high speeds.
FB40-ND1 offers WiFi Hotspot functionality. WiFi and Cellular transmissions will happen
simultaneously. The WiFi and Cellular antennas are not collocated: WiFi antenna is inside the
TCU while the cellular antennas are on the roof top of the vehicle.

2.0 ELECTRICAL HARDWARE DESCRIPTION
2.1 POWER & GROUNDING
The TCU is designed to operate via an unfiltered 5 A fused input from the vehicle battery: Vbatt
Ground return is through a single ground pin: GND
2.1.1 Power – Operating Voltage
Operating voltage range is provided in the following table.
Table 3.1.1 TCU Operating Voltage Conditions
VOLTAGE
RANGE (Vdc)
SUBSYSTEM OPERATING CONDITIONS
9.0 < V
BATT
< 16.0
Normal operation. TCU is fully functional
2.1.1.1 Start/Stop Voltage Conditions
In addition to the normal operating voltage ranges listed above, the TCU must also remain
operational during engine start/stop events.
2.1.2 TCU Interface to External Cellular Antennas
The TCU has FAKRA connectors to which external LTE/GSM antennas may be connected. TCU
operates with external cellular antennas having cable length of at least 25 cm or longer.
Purple RF connector is for the primary TX/RX operation and beige connector is for RX diversity
only.
2.2 WIFI
The TCU supports IEEE 802.11a/b/g/n/ac 2.4/5GHz WiFi. TCU operates as a Personal Access
Point. Signal Specifications
Within the coverage areas, the WiFi signal from the TCU has a speed up to 20 Mbps with a bit
error rate of less than 2%. All coverage areas assume that the packaging guidelines referenced in
this document have been adhered to.
2.2.1 WiFi internal Antenna
The TCU contains integrated pcb type F dual band antenna with the following maximum gain
Frequency MAX Gain
2442 MHz 3.14 dBi
Continental Pripriotary Confidential
5220 MHz 0.68 dBi
5785 MHz 1.94 dBi
2.3 TCU LABELING
TCU labeling shall comply with the regulatory homologation compliance mark(s) that are
required by law in the country.
2.3.1 Automotive OEM Labeling Conditions
The module is marked with the Automotive OEM company trademark, engineering part number,
and supplier code.
2.4 WIFI TCU ANTENNA TRANSMIT AREA
The TCU is designed to allow the Wi-Fi antenna signal to propagate out of the top, bottom, and
sides of the module, as shown in the figure below.
Continental Pripriotary Confidential
3.0 VEHICLE INSTALLATION GUIDELINES
The sheet metal cover is designed to be a heat sink. A gap between the heat sink and the mounting
surface is recommended to facilitate heat transfer out of the module. Exceptions can be made if
the module is mounted to a surface that can help facilitate heat transfer such as a large aluminum
body panel.
The device does not have sealed connectors.
It is designed to meet Class I water intrusion conditions (no drip test required), so it should not be
placed in area that can get wet.
Continental recommends that the automotive OEM uses the mating harness supplier’s
recommendations for the keep out zone around the connectors to ensure proper mating of each
connector.
The device is limited to installation in mobile applications, according to Part 2.1091(b). No other
operation configurations are allowed.
Changes or modifications to this system by other than a facility authorized by Continental could
void authorization to use this equipment.
The device and its antennas must be installed to provide a separation distance of at least 25 cm
from all persons and must not be co-located or operate in conjunction with any other antenna or
transmitter.
4.0 REGULATORY COMPLIANCE NOTES

México
La operación de este dispositivo está sujeta a las siguientes dos condiciones:
(1) Este equipo o dispositivo no deberá ocasionar interferencias perjudiciales.
(2) Este equipo o dispositivo debe aceptar cualquier interferencia recibida, incluidas aquellas que
pudieran causar un funcionamiento no deseado.
5.0 EXTERNAL ANTENNA REQUIREMENTS FOR USE WITH FB40-ND1 TCU
The FB40-ND1 device is for use with external antennas ONLY, except for WiFi which uses
an internal antenna.
For all LTE/WCDMA/GSM operating bands the maximum antenna gain including cable loss
shall not exceed the following values:
GSM 850: 1 dBi
GSM 1900: 1 dBi
