Another experiment [Integrive-100 MIMO SDR] : How far can we push it?
Hi everyone,
Following up on my previous demo, my team and I decided to take the Integrive-100 out for a real-world stress test. I wanted to see how our architecture handles a challenging Non-Line-of-Sight (NLOS) environment in an urban setting.
The Setup:
Distance: 207m (Straight-line distance)
Environment: Dense urban with buildings (NLOS)
Placement: Transmitter on a building rooftop / Receiver at ground level.
Frequency: 915 MHz
Bandwidth: 5 MHz
Modulation: QPSK
FEC: Reed-Solomon (Code Rate: 0.8)
Tx Power: 18.5 dBm
The Results:
Measured SNR: 17 ~ 19 dB
Packet Error Rate (PER): 0.13% (0.0013) No retransmissions
Throughput: 5.5 Mbps
The high SNR margin suggests our RF front-end and signal processing are operating efficiently, leaving significant headroom for more challenging environments or longer distances. At 5.5 Mbps (69% efficiency including slot-based MAC overhead), the link provides enough capacity to support stable, real-time video or audio streaming. Our focus remains on fixing the 'hardware plumbing' so that your algorithms can reach their maximum theoretical potential.
How many of you are also taking your setups out of the lab?
I’d love to compare notes with anyone else doing field work!
