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 device. If Continental chooses to re-use modular approval, then the TCU shall be clearly labeled with an external label containing the integrated modems FCC ID. For example, the label can include text Contains device with FCC ID: LHJ-BL28EU001. 4 Antenna requirements for use with BL28EU-001 module:

The module must be installed to provide a separation distance of at least 20cm from all persons and must not be co-located or operating in conjunction with any other antenna or transmitter. The BL28EU-001 module is for use with external antennas ONLY. For all LTE/WCDMA operating bands the maximum antenna gain is 5 dBi including cable loss. The maximum gain of the antenna path (cable loss + antenna gain) shall not exceed the above mentioned values. This radio transmitter (FCC ID: LHJ-BL28EU001) has been approved by FCC and Industry Canada to operate with the antenna types listed below with the maximum permissible gain indicated. Antenna types not included in this list, having a gain greater than the maximum gain indicated for that type, are strictly prohibited for use with this device. 5 Instructions to OEMs:

Continental must instruct the automotive OEM and provide them to include the following information into the car users manual (i.e. for the DCM):

1. End-users must be provided with transmitter/antenna installation requirements and operating conditions for satisfying RF exposure compliance:

2. A separate section should clearly state FCC RF Exposure requirements:

3. Required operating conditions for end users. 4. The antenna used with this device must be installed to provide a separation distance of at least 20cm from all persons, and must not transmit simultaneously with any other transmitter, except in accordance with FCC multi-transmitter product procedures. 5. The Maximum ERP/EIRP and maximum antenna gain required for compliance with Parts 15, 22H, 24E, and 27. 6. Clear instructions describing the other partys responsibility to obtain station licensing. BL28EU-001 OEM Manual and User Guide 6 Layout and Routing Recommendations Module Specific 6.1 The pad spacing of 1mm should allow the placement of a 600um finished VIA between pads, while maintaining a 200um Via- to-trace or Via-pad spacing, to facilitate the breakout of inner row signals. The 1mm spacing is also large enough to route two 200um (8 mil) traces between pads. Figure 6-1 Vias placed between Pads 6.2 The NAD has three antenna pins. RF Traces for antennas PRIMARY_ANT SECOND_ANT GNSS_ANT The figure below shows the general breakout of the module:

BL28EU-001 OEM Manual and User Guide Figure 6-2: NAD Pin Breakout The module should be oriented on the main board to minimize the length of the PRIMARY_LTE antenna pin (LTE Ant1). This 50ohm line should be as short as possible to the external RF connector or internal antenna feed point. The RF traces from the NAD antenna pins on the main board can be stripline or microstrip. For the stripline approach, vias should be placed to the NAD EDGE SIDE of the pins as close as possible to the NAD antenna pads to minimize any impedance discontinuity (see figure 38). For the microstrip approach, the PCB insertion loss will be less but the short route under the NAD MUST BE TREATED AS STRIPLINE SO IT WILL BE NARROWER UNDER THE NAD THAN THE MICROSTRIP LINE. The NAD has ground cleared out under the RF antenna routes as shown below:

BL28EU-001 OEM Manual and User Guide Figure 6-2: Antenna Pad Ground Cutout (Top View) For routing microstrip lines UNDERNEATH the NAD on layer 1, these ground cutouts internal to the NAD need to be accounted for in the stripline calculation. The internal GND height and dielectric constant of the NAD board are shown below:

H = 19.3 mils (491 micron) Dielectric Constant = 4.1 For example, consider the following stackup for a main PCB:

Assume the main PCB above with a 6 layer stackup with ground cut away on layer 2 so the microstrip lines reference ground on layer 3. The dielectric thickness from L1 to L3 is 21.2 mils. Figure 6-3 BL28EU-001 OEM Manual and User Guide Using an online impedance calculator, the line width under the NAD for a 50 ohm line is 16.9mils

(433micron) shown below:

BL Figure 6-4 The calculation for the microstrip line width outside the NAD is 37.7mils (967micron) shown below:

Figure 6-5 Due to the nature of the weave chosen for each PCB, the dielectric constant of the NAD board is 4.1 while the main board is 4.3. A dielectric constant of 4.2 was chosen in the stripline calculation, while 4.3 was used for the microstrip calculation. Main board stack up may vary so these line widths may need to be recalculated. IT IS HIGHLY RECOMMENDED TO USE A SIMILAR STACKUP AS SHOWN IN FIGURE 39 WITH MICROSTRIP ROUTING AND GND CUTS ON LAYER 2 WITH GND REFERENCE ON LAYER 3. THERE SHOULD BE NO ROUTING ON L2 AND SOLID GND ON L3 UNDERNEATH THESE ANTENNA LINE MICROSTRIP TRACES. BL28EU-001 OEM Manual and User Guide The antenna traces need to routed STRAIGHT OUT OF THE NAD TO THE NEAREST NAD EDGE. The lines need to be tapered from 433micron to the 967micron width gradually but quickly. Figure 6-6 These line widths may vary depending on the stackup selected for the main board. 6.3 RF Antenna Layout Parameters Type of Guidance Trace impedance Total route length Ground between signals Spacing to other signals Requirement 50-Ohms 10% single-ended

<100-mm

> 3 x line width of ground trace between, stitched VIA to ground

< 3:1 Signals should be routed along similar route path, but separated by ground trace. Trace impedances should match the table, either as microstrip or stripline. Total length for both signals should match the table. Spacing to ground or other signals on outside of bundled signals should match the table.
