Introduction
This guide provides information on the installation and operation of the Vayyar V60G-HOME-I
modules.
V60G-HOME-I is a family of multi-antenna millimeter-wave modules operating at 60GHz bands, based
on the company’s VYYR7201 RF SoC, generating a 3D image of the sensor’s vicinity by transmitting and
receiving mm-wave signals from multiple antennas (MIMO), used as a fixed field disturbance sensor or
a short-range device for interactive motion sensing.
Models pertaining to the V60G-HOME-I family are intended to be integrated with an additional host,
either a PC-host operating the device through a USB interface, or a microcontroller-unit (MCU) for
integrated and embedded products.
The sensor detects objects in a defined arena and provides 3D-data of the targets to the host, such as:
position within the arena, class or posture; a raw 3D image (point-cloud for example).
Typical applications for the device can be touchless input device (e.g. gesture-recognition interface),
in-room people detection and monitoring for improving comfort and energy-utilization optimization
(e.g. HVAC operation and airflow optimization), detection of abnormal conditions such as fall of elderly
people and apnea in adults and babies, and in-cabin monitoring for detection of infants left in car.
The models participating in the V60G-HOME-I family (and certified under modular-approval) include,
but not limited to: vStraw_CTPB4_I, vBLU_OK_CTPB4, vBLU_MW_CTPB4.
1.1 Release Information Note
Software capabilities, algorithmic capabilities and different features are under continuous
development and improvement.
This document provides basic description of the system and it is operated. For more details –contact

System Overview
2.1 System Architecture
The V60G-HOME-I system may be operating with a host-PC and dedicated control and imaging SW
and GUI (for example an “EVK” architecture), or by running an imaging engine on a dedicated DSP
embedded into the proprietary VYYR7201_CTPB4 chips and using a dedicated API to extract the
processing outputs (“embedded architecture”), or any combination of the two.
An “EVK” architecture and connectivity scheme is illustrated in the figure below.
Figure 1: V60G-HOME-I “EVK” System Architecture
The “EVK” V60G-HOME-I system is comprised of the following components:
The V60G-HOME-I RF Sensor module.
The EVK Engine. Host software that performs signal processing functions. The software
runs in a command window in a PC, which is connected to the V60G-HOME-I Sensor via a
USB cable.

V60G-HOME-I User Guide

Web GUI. User-interface client software that communicates with the EVK Engine via a
TCP/IP connection.
API Client. Optional, customer-developed software that communicates with the EVK
Engine via a TCP/IP connection.
A typical “Embedded” architecture is depicted in the following figure:

2.2 Hardware
The figure below presents a high-level block diagram of the PCB that houses the USB-based sensor
unit:
Figure 3: High-Level Block Diagram –USB-based system
An SPI-based module is similar, excluding the USB-related components. The following components
are embedded in the sensor unit PCB:
Vayyar VYYR7201-B4 system-on-chip (SoC).
46 embedded Tx/Rx linear polarized PCB embedded, wide-band antennas.
A Crystal used as a clocking source for the Cypress MCU.
A TCXO (Temperature Compensated Crystal Oscillator) used as a clocking source for the
VYYR7201-B4 SoC.
Power supply system supporting 3.3V, 2.5V, 1.27V and 1.2V DC/DC converters.
For USB-based models - a digital interface that communicates with a host PC via a USB-2.0
connection. The interface is implemented using on-board Cypress micro-controller unit
(MCU).
For SPI-based models –the interface is communicating directly with VYYR7201- B4 SoC.

2.2.2 Digital Interface
The V60G-HOME-I models use either USB 2.0 or SPI as digital-interface, connecting the host module
to the sensor module.
The USB interface is implemented on the module using an MCU and a micro-USB connector. The SPI
interface is connected directly to the VYYR-7201-B4 chip, through a board-mounted multi-pin
connector.
Micro-Controller Unit (MCU)
Cypress’s EZ-USB FX3™ MCU integrates the USB 2.0 physical layers (PHYs), and contains a 32-bit
ARM926EJ-S microprocessor for building custom USB SuperSpeed applications. The integrated
processor contains a unit called General Programmable Interface (GPIF), which provides easy
connectivity to popular interfaces.
USB Connector
The onboard micro-USB-B 2.0 connector is used for power supply and for data transfer between the
sensor unit and the host PC. The connector supports the USB 2.0 protocol in High-Speed Mode (480
Mbps).
Figure 4: vStraw_CTPB4_I Connectivity
SPI Interface
Modules which are using SPI interface, the digital-interfaces and power supply are fed through a
dedicated connector. The exact connector used changes per specific model, for example
VBLUOK_CTPB4 uses OK-06F030-04.

2.2.3 RF Interface - Antennas
The array of 46 antennas serves to connect the sensor unit with the environment. The antennas are
embedded in the PCB, as depicted in the figure below.
Figure 6: Antenna Positions and Numbering
For each transmitting (TX) antenna, there are multiple receiving (RX) antennas for collecting and
recording the received RF signals. Each RX antenna and its associated TX antenna serve as an
antenna pair.
All 46 antennas are from the same antenna type, which is linear polarized PCB embedded, wide-
band antennas.
2.2.4 Electrical Specifications
The following electrical specifications are for the sensor unit. The current consumption specifications
are based on lab measurements performed by Vayyar.

2.3 Software
The V60G-HOME-I system software performs signal processing and generation of the arena image,
either on a host-device, or on an embedded DSP processor.
The software generates a 3D image and a point-cloud corresponding to the detected objects in the
arena, and may extract further details through more advanced algorithms (for example –fall-
detection, breathing waveform monitoring etc). The data can be obtained either using a dedicated
API (see detailed module SW manual), or a Graphical User Interface (GUI).
The following diagram describes a typical processing flow of the software.

3.2 Instructions for the Integrator
The OEM integrator is responsible for ensuring that the end-user has no manual instructions to
remove or install module.
3.2.1 OEM Integrators Notices
This device is intended only for OEM integrators under the following conditions:
The transmitter module may not be co-located with any other transmitter or antenna. As long as this
condition above is met, further transmitter testing will not be required. However, the OEM
integrator is still responsible for testing their end-product for any additional compliance
requirements required with this module installed.
IMPORTANT NOTE: In the event that this condition cannot be met (for example certain laptop
configurations or co-location with another transmitter), then the FCC/ISED authorization is no longer
considered valid and the FCC ID/IC number cannot be used on the final product. In these
circumstances, the OEM integrator will be responsible for re-evaluating the end product (including
the transmitter) and obtaining a separate FCC/ISED authorization.

V60GHOMEI”(either in user-manual, on the package or the product case).
When the hosting device uses an electric-display in a product, it should be possible to display
electronically the FCC-ID.
3.2.3 OEM Manual Information that Must be Included
The OEM integrator has to be aware not to provide information to the end user regarding how to
install or remove this RF module in the user manual of the end product which integrates this
module.
The user manual for OEM integrators must include the following information in a prominent
location:
IMPORTANT NOTE: To comply with FCC/ISED RF exposure requirements, this device and its antennas
