Wi-Fi

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 operation. This module should be 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. The

label for the end product must include FCC ID: BEJTM05GTJN or A RF
transmitter inside, IC: 2703H-TM05GTJN.
