Overview
Introduction
The radar module “RSMV2” from LG Electronics is a compact millimeter wave detection sensor optimized for detecting minute movements of objects at close area. Its main use is a presence detection sensor that checks the presence of people in various indoor and outdoor environments and has the advantage of being easy to install while minimizing sensor exposure. It also has an embedded program to enable configuration in response to various application requirements. By adopting Infineon’s radar sensor BGT60UTR11AiP, it supports an easy-to-use FMCW (Frequency Modulated Continuous Wave) radar platform. In particular, the AIP (Antenna In Package) structure, which has an antenna built into the radar chip, makes it possible to provide stable RF characteristics even if the size is small.
Features
- 61-61.5GHz radar sensor for presence detection.
- 1Tx – 1Rx Antenna
- Synthesized FMCW frequency source
- Back-channel UART through USB-to-PC for logging purposes
- Antenna in package (AIP)
- 12V power input.

FCC Statement
FCC Part 15.19 Statements:
This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions:
- This device may not cause harmful interference, and
- this device must accept any interference received, including interference that may cause undesired operation.
FCC Part 15.21 statement
Any changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate this equipment.
Regulatory notice to host manufacturer according to KDB 996369 D03 OEM Manual v01>
List of applicable FCC rules
This module has been granted modular approval as listed below, FCC rule parts.
FCC Rule parts 15.255
- Summarize the specific operational use conditions
-The OEM integrator should use equivalent antennas which is the same type and equal or less gain then an antenna listed below in this instruction manual. - Limited module procedures (Only limited modular approval) N/A
- Trace antenna designs (Only trace antenna module) N/A
This device is not using trace antenna.
RF exposure considerations
The module has been certified for integration into products only by OEM integrators under the following conditions:
- The antenna(s) must be installed such that a minimum separation distance of at least 20 cm is maintained between the radiator (antenna) and all persons at all times.
- The transmitter module must not be co-located or operating in conjunction with any other antenna or transmitter except in accordance with FCC multi-transmitter product procedures.
- Mobile use
As long as the three conditions above are met, further transmitter testing will not be required. OEM integrators should provide the minimum separation distance to end users in their end-product manuals.
- Mobile use
- Antennas
- This module is certified with the following integrated antenna.
- Type: Single patch Antenna in Package / Peak Gain: 3 dBi
Any new antenna type, higher gain than listed antennas, should be met the requirements of FCC rule 15.203 and 2.1043 as permissive change procedure.
Label and compliance information
- End Product Labeling (FCC)
The module is labeled with its own FCC ID. If the FCC ID is not visible when the module is installed inside another device, then the outside of the device into which the module is installed must also display a label referring to the enclosed module. In that case, the final end product must be labeled in a visible area with the following: - “Contains FCC ID: BEJ-RSMV2
Information on test modes and additional testing requirements - OEM integrator is still responsible for testing their end-product for any additional compliance
requirements required with this module installed (for example, digital device emissions, PC peripheral requirements, additional transmitter in the host, etc.). - Additional testing, Part 15 Subpart B disclaimer
The final host product also requires Part 15 subpart B compliance testing with the modular transmitter installed to be properly authorized for operation as a Part 15 digital device.
Note EMI Considerations
- Note that a host manufacturer is recommended to use D04 Module Integration Guide, recommending as “best practice” RF design engineering testing, and evaluation in case non-linear interactions generate additional non-compliant limits due to module placement to host components or properties
- For standalone mode, reference the guidance in D04 Module Integration Guide, and for simultaneous mode, see D02 Module Q&A Question 12, which permits the host manufacturer to confirm compliance.
How to make changes
Since only Grantees are permitted to make permissive changes, when the module will be used differently than granted, please contact the module manufacture on below contact information.

<ISED Statement>
RSS-GEN, Sec. 7.1.3–(licence-exempt radio apparatus) This device complies with Industry Canada licence-exempt RSS standard(s).
Operation is subject to the following two conditions:
- This device may not cause interference, and
- This device must accept any interference, including interference that may cause undesired operation of the device.
RF Exposure
The antenna (or antennas) must be installed so as to maintain at all times a distance minimum of at least 20 cm between the radiation source (antenna) and any individual. This device may not be installed or used in conjunction with any other antenna or transmitter.
End Product Labeling (ISED)
The module is labeled with its own IC Certification Number. If the IC Certification Number are not visible when the module is installed inside another device, then the outside of the device into which the module is installed must also display a label referring to the enclosed module. In that case, the final end product must be labeled in a visible area with the following: “Contains IC: 2703N-RSMV2
