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!

Best Microsoft Teams Android app and Webex mobile calls noise cancelling setup?

I'm a remote worker that wants the best noise cancelling performance when in meetings/calls in Microsoft Teams Android app and Webex when I'm travelling extremely loud trains, etc.

I wanted to plug in my DJI Mic Mini Mobile Receiver into my phone via USC-C port on my Samsung Fold 7 phone (does not have a headphone jack).

And then output the meeting audio via either my phone speakers or wired earphones at least, or ideally Bluetooth earphones. But I don't think there's anything that can solve this, right? Is there?

Gemini AI said only way is via a clunky splitter which I wouldn't want or via DJI Mic 3 receiver and use wired headphones on its 3.5mm headphone jack (expensive).

My Requirements:

• Input audio - voice via DJI Mic (best noise cancelling performance possible)

• Output audio - meeting voices via phone speakers or wired earphones at least, or ideally Bluetooth earphones.

• Above only using phone, MS teams Android app, and Webex.

Do Proxies Actually Improve Privacy on Untrusted Networks?

Hey everyone, looking for some advice from people experienced - I’ve been digging into ways to better protect traffic on public and semi-trusted Wi-Fi networks (cafes, coworking spaces, etc.), and I keep running into discussions about using proxies as an additional layer alongside VPNs or instead of them in some cases.

I understand the basics, but I’m unsure how practical proxies really are for everyday privacy and whether they meaningfully reduce exposure to common threats like traffic sniffing or tracking. I recently came across a provider called Froxy while researching rotating proxies and it got me thinking about how these services actually perform in real-world setups, especially in terms of latency, reliability, and whether they introduce new risks. For those of you who have implemented proxy solutions in your workflow or network setups, how do you approach choosing a provider and configuring things securely, and are there specific pitfalls or misconceptions I should be aware of before going deeper into this?

Xiaomi AX3000 Secondary mesh node won't pair wirelessly. Solid orange LED on hard reset

Hey guys, hoping someone here can help because this Xiaomi AX3000 mesh setup is driving me crazy.

My main router in the living room is connected to my ISP and working perfectly (I even locked 5GHz to channel 44 at 160MHz with Smart Connect on to avoid any DFS drops). The problem is my secondary node in the bedroom.

Here is what happened: Out of the box, the Xiaomi app wouldn't pair it, so I used the physical mesh buttons on the routers. It worked fine and both LEDs were solid white. But the very next morning, it had completely dropped the wireless connection and the top system LED was solid orange.

I tried plugging it into the main router via ethernet and it paired flawlessly again. But the second I unplug the cable to go back to wireless backhaul, it fails and the top LED goes solid orange again.

I did a standard 10s soft reset. It boots up as a standalone router (bottom LED solid white, top LED completely off) but absolutely refuses to enter pairing mode. Pressing the physical mesh button does nothing, and the app/web can't find it.

So I tried a hard reset on the secondary node (held the reset button, plugged in power, kept holding for 15s). When I do this, the bottom LED blinks orange for about 3 seconds, and then just stays solid orange permanently. The top LED remains completely dead.

The biggest catch: I'm on a Mac, so I can't just run the official Windows MiWiFiRepairTool.exe.

Has anyone seen such a thing before?what can I do to make things work again?

Thanks in advance!

Thoughts? - Fixed Wireless Deployment B41

I’m preparing to deploy fixed wireless broadband.

Band 41, 30mhz contiguous channel + additional 10mhz channel if needed. 4T4R @ 46 dBm power.

My propagation is showing me -105db up to and beyond 12 miles SSRP.

I’ll be creating 2 classes of CPE, one for those within -90db and one for those beyond -90db, again SSRP. Idea here is to use a 9dbi receiver for most and a 15-18 dbi receiver for the “tricky” service points.

I feel like -105db at 12 miles away is outrageous. Am I right?

Transferring Assurance

Has anyone needed to switch an assurance wireless (lifeline) account to another phone and had success doing it? I’m trying to transfer my phone number to a new phone, but having no luck with any instructions I’ve found online and can’t get their customer support to work.

Found a project that lets you explore how AI-based beam prediction models behave using simulation + XAI tools

You can:

  • visualize beam patterns
  • see which inputs influence predictions
  • test how changes in environment affect the selected beam

Feels useful for debugging and understanding model sensitivity, especially in more complex scenarios.
