1.7. CSI measurements over a large and continuous spectrum by QCA9300

PicoScenes unlocks the arbitrary tuning for carrier frequency for the QCA9300 NIC. More specifically, QCA9300 can operate at any carrier frequency between 2.2 to 2.9 GHz in the 2.4 GHz band and 4.4 to 6.1 GHz in the 5 GHz band. PicoScenes uses the --freq command option to specify the carrier frequency, e.g., --freq 4900e6. For more details, you may refer to The academic paper of PicoScenes.

Continuous and overlapped CSI measurements over a large spectrum can be obtained via PicoScenes on QCA9300.

Hint

Why do the CSI measurements misalign with each other? Do you wanna stitch them together? You may refer to The academic paper of PicoScenes.

1.8. CSI measurements under tunable and wide baseband bandwidths

For the QCA9300 NIC, PicoScenes unlocks the fine-grained tuning for baseband bandwidth from 5 to 80 MHz with a minimum step of 2.5 MHz. PicoScenes also provides up to 200 MHz baseband bandwidth on the SDR devices. PicoScenes uses --rate command option to specify the baseband bandwidth for both the commercial Wi-Fi NIC and SDR frontends, e.g., –rate 55e6. For more details, you may refer to The academic paper of PicoScenes.

PicoScenes provides the out-of-box CSI measurement functionality for the tunable and wide bandwidths.

1.9. Live CSI measurement and plot using HackRF One

PicoScenes supports the most cost-efficient SDR devices, HackRF One. With this only 200$ SDR, Wi-Fi sensing researchers can perform 802.11a/g/n/ac/ax packet injection, receive standard 20-MHz bandwidth packet in realtime, and access the comple PHY-layer information. For more information, please visit PicoScenes now officially supports HackRF One.

1.10. User tuneable Rx gain for the QCA9300 NIC

For the QCA9300 NIC, PicoScenes unlocks the manual Rx gain control for all three radio chains. With this feature, PicoScenes eliminates the troubles caused by the automatic gain control (AGC), and researchers can obtain continuos and smooth CSI amplitude measurements across packets.

1.11. 27-NIC Wi-Fi sensing array

To fully demonstrate the capacity of multi-NIC CSI measurement, we setup a 27-NIC Wi-Fi sensing array. The array contains 27 QCA9300 NICs and 10 1-to-3 PCI-E bridge adapters. For more details, you may refer to the evaluation part of The academic paper of PicoScenes.

1.12. Large spectrum stitching using two QCA9300 NICs

This short video demonstrates the spectrum scanning and stitching using the PicoScenes platform and two QCA9300 NICs. I upload the same video to both YouTube and Youku (for China mainland users).
