Use Cases

Use case 1:
Cooperative communication and multi-static sensing based on OFDM waveform

PoC typical setup for ISAC in a cell-free wireless network context with Wi-Fi OFDM waveform.

Objective:

Develop and validate cooperative MIMO multi-static sensing algorithms to enable high accuracy localisation and tracking and high-resolution 3D imaging.

01
This PoC will demonstrate the synchronised data collection in a distributed setup with FPGA based customised Wi-Fi nodes (AP + multiple Stations) for joint multi-static sensing and communication.
02
This PoC will demonstrate the centralised data processing algorithm for advanced sensing features, such as high accuracy localisation/tracking and 3D imaging.

The goal of this PoC is to show ISAC in a cell-free wireless network context with Wi-Fi OFDM waveform. One Wi-Fi station communicates with user equipment running some local/internet traffic. Two stations (could be the receiver of the same station involved in the communication or a new station) decode the reflections from the transmission and generate range-Doppler maps that are combined to generate a multi-static view of the environment. The typical setup of this PoC as illustrated below.

Use case 2:
Generation and Robust Distribution of References to Synchronise Network
Objective:

System timing and synchronisation:

01
Using photonics to generate a very precise clock reference with ultra-low phase noise.
02
Point-to-multipoint synchronisation for massive MIMO edge network with ultra-low timing jitter at a range of frequencies extending up to the mm-wave.
03
Demonstration of SWaP-C reducing by using photonic integrated circuits and sharing the photonic core among several sensors.

The work will include experimental testing of all the subsystems of the data and clock distribution to the Remote ISAC transceivers depicted, including the Master Optical Clock, the multichannel TRx and Rx transceivers designed and structured as Photonic Integrated Circuits (PICs) and the Remote ISAC transceivers (RISACTs). The synchronisation and data transmission of point-to-multipoint ISAC signals will be experimentally tested. A massive MIMO edge network with more than 1000 edges will be experimentally emulated in Lab.

Use case 3:
Use liquid crystal technology from Antenna to RAN

PoC3 scenario illustration

Objective:
01
To demonstrate the integration of radio-sensing and communication technologies through the use of phased array antennas in a 6G perceptive network.
02
To validate the control phases of the phased array antenna using liquid crystal technology in an end-to-end manner, from the antenna to the RAN.
03
To validate the antenna capabilities in the real world for radio-sensing, radio localisation and tracking application.

The PoC scenario will test the communication between a BS and mobile user (end terminal, vehicle, or drone) using the phased array antenna designed by SOD with eBOS testbed facilities. The PoC will be able to localise the user, transmit the information and track the user. Figure below shows an illustration of a potential scenario.

Step 1: Validate the antenna performances

Step 2:  Integrate the phased array antenna in a communication system infrastructure

Step 3:  Qualify the antenna in real-world conditions.

If the PoC is successful, the phased array antenna may be used as a component of future 6G networks.
