VDC (Vehicle Domain Controller) supports highly integrated multimode,
multiband RF CMOS transceiver IC. It provides a single-chip solution for LTE
carrier aggregation support up to 20 MHz+20 MHz for 2DLCA. For the WiFi,
Qualcomm engine are used. Overall the VDC directly supports with up to 2 GSM
bands, 3UMTS bands and 6 FDD-LTE bands with 2DLCA. Additional Qualcomm IC as
QCA6574 support WiFi 11ac.
VDC is operating with LGE shark antenna approved for use with the device.
RFx information
The strength of the RF field produced by the wireless module or modules
embedded in the TCU is well within all international RF exposure limits known
at this time. Because the wireless modules embedded in the TCU emit less than
the maximum amount of energy permitted in radio frequency safety standards and
recommendations, the manufacturer believes these modules are safe for use.
Regardless of the power levels, care should be taken to minimize human contact
during normal operations. This module should remain more than 20 cm (8 inches)
from the body when wireless devices are on and transmitting.
This transmitter must not be collocated or operated in conjunction with any
other antenna or transmitter. Operation is subject to the following two
conditions: (1) this module does not cause interference, (2) this module
accepts any interference that may cause undesired operation.
Information for the integrator
The integrator must not provide information to the end-user regarding how to
install or remove this RF module in the user manual of the end product. The
user manual that is provided by the integrator for end-users must include the
following information in a prominent location. To comply with FCC RF and IC
RSS‐102 exposure requirements, the antenna used for this transmitter must be
installed to provide a separation distance of at least 20 cm from all persons
and must not be collocated or operated in conjunction with any other antenna
or transmitter.
Approbation FCC
This module complies with FCC/IC rules.
FCC : Part 15, Part 22, Part 24, Part 27, Part 90
ISED : RSS-130, RSS-132, RSS-133, RSS-139, RSS-199, RSS-247
Furthermore, this device complies with FCC radiation exposure limits set forth
for uncontrolled environments.
This module must be installed and operated with a minimum distance of 20 cm
between the radiating element and the user.
This module must not be co-located with any other transmitters or antennas.
To comply with FCC regulations limiting both the maximum RF output power and
human exposure to RF radiation, the maximum antenna gain including cable loss
in a mobile-only exposure condition must not exceed the values listed in the
following table.
| Band | Frequency Range [MHz] | Maximum Antenna Gain[dBi] |
|---|---|---|
| GSM850 | 824~849 | -3.57 |
| GSM1900 | 1850~1910 | 0.01 |
| WCDMA(B2) | 1850~1910 | 0.01 |
| WCDMA(B4) | 1710~1755 | 0.33 |
| WCDMA(B5) | 824~849 | -3.57 |
| LTE(B2) | 1850~1910 | 0.01 |
| LTE(B4) | 1710~1755 | 0.33 |
| LTE(B5) | 824~849 | -3.57 |
| LTE(B7) | 2500~2690 | -3.61 |
| LTE(B12) | 699~716 | -2.61 |
| LTE(B26) | 814~849 | -4.30 |
To satisfy the FCC’s exterior labeling requirements, the following text must
appear on the exterior of the end product.

Changes or modifications to this equipment may cause harmful interference
unless the modifications are expressly approved in the instruction manual.
Users may lose the authority to operate this equipment if an unauthorized
change or modification is made.
Note: If this module is intended for use in a portable device, additional
testing will be required to satisfy the RF exposure and SAR requirements of
FCC Part 2.1093 and RSS-102.
This device complies with part 15 of the FCC Rules. Operation is subject to
the following two conditions: (1) This device may not cause harmful
interference, and (2) this device must accept any interference received,
including interference that may cause undesired operation.
Note: The OEM integrator is responsible for ensuring that the host product which is installed and operating with the module is in compliant with Part 15B unintentional Radiator requirements, please note that For a Class B digital device or peripheral, the instructions furnished the user manual of the end‐user product shall include the following or similar statement, placed in a prominent location in the text of the host product manual:
Note ： This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation.
If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of the following measures:
- Reorient or relocate the receiving antenna.
- Increase the separation between the equipment and receiver.
- Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
- Consult the dealer or an experienced radio/TV technician for help.
Approbation IC
The device applies the following requirements persuant to RSS-247 additional requirement.
