Video Summary - ISAC Integrated Sensing And Communication / JCAS Joint Communication and Sensing

Summary of Technological Concepts / Platform Features

An Integrated Sensing and Communication (ISAC) demo was presented at RC 2023 by TMYTEK (with the Zostack founder).
The showcased system is a “mini meter wave platform” designed for joint communication and sensing, also referred to as JCAS / ISAC.

The platform is based on USRP-2974.
It uses frequency translation / “frequency version” steps, because the RF front-end components (subsystem) can only generate signals after CPRS (exact term unclear due to subtitle noise).
Main functional blocks:
- A “beamforming box” using a 4×4 array for transmitter/receiver beamforming.
- A “pure passage” / circuit path for signal handling (designed by TMYTEK; exact naming unclear).

The demo uses OFDM signals for communication.
It also generates/uses a radar sensing signal to measure distance between:
- the beamforming box and a reflector.
The system supports two layers of sensing/visualization:
- Physical-layer diagrams, showing communication + radar signals together.
- Application-layer reporting, including live video/stream measurement displays (example shown as “live stream from the upper layer”).

The demo illustrates the relationship between communication and sensing:
- Blocking the beamforming signals with a hand causes the video stream to be blocked.
- Removing the hand restores the video quickly.
The subtitles emphasize that the application-layer can represent the sensing/communication effect (e.g., video availability) rather than only showing raw RF/PHY signals.
