Most routers have the SoC integrating the radio chip, and running firmware and the OS on the same silicon.
- wtallis 7y agoWireless router SoCs usually have at most one radio integrated, and the 5Ghz radio is still usually attached over PCIe. And even the integrated 2.4Ghz radio's firmware is running on entirely separate processor cores and in a different memory address space from the application processor.
- milankragujevic 7y agoI did not know that the firmware for the radio is running in a different context (memory space/processor). I assumed they would, to save cost, run everything together.
