The first WiFi-7 tri-band router on the Qualcomm's Alder IPQ9574 platform. https://lnkd.in/dCrn4YN6

Some project details:

  Tri band 4x4 MIMO 2.4GHz /ax + 4x4 MIMO 5GHz /be + 4x4 MIMO 6GHz /be   IoT ZigBee module with coexictence mode   10G WAN port   4x2.5G LAN ports    13 antennas   USB3.1 Host   Passive cooling (max TDP > 30W)   Six layer PCB   eMMC + DDR3 1GByte   Thermoflow simulation Lightpipe optical simulation   Smart RGB "ring" LEDs multimode indication   Touchbutton power on/off   The schematic diagram contains 53 pages   Three PCB - mainboard, LED and FPC touchbutton   The full production bundle consist > 40 documents

It was developed over a year ago by a product team of four designers in 3 months! There was one mistake made during the first EVT iteration only. After the fix it booted and worked without problems.

It seems, we developed it too early. A year later, there was only one similar router on the market from the Xiaomi.

My most favorite and complicated PET project.

Six years ago I decided to get an amateur radio call sign and make my own SDR DDC/DUC transceiver. What happened as a result?

  1. I've got callsign - UT2UK
  2. 7 types of PCBA * 3 releases = 21 PCBA samples
  3. The mechanical design - 20 parts * 2 releases (laser cut, metal stamping, milling, laser engraving etc)
  4. The 32 GIT repos. The main module repo consists > 70K C/C++ code lines
  5. The four different HW platforms - TI's TMS320C67xx , ARM9, Ti's PRUSS controllers, MCU M51 from Nuvoton
  6. The technological stacks: QNX ARM C/C++, DSP C/ASM, Matlabs , Ti' PRUSS C, M51, C, JS for the WEB remote control , Intel FPGA Verilog etc
  7. Over $10K expenses - R&S spectrum analyser, signal generator, Anritsu VNA, 50 ohms loading, R&S power detector from eBay etc
  8. More than 70 users in different countries

What's next - a new version of the transceiver. It seems like it will never end 🤔
