User Guide
Chapter 1 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.

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.

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 FX3TM 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, wideband antennas.

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 falldetection, 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.
