Source? This seems unlikely considering the existence of legal SDR. Also proprietary blobs seem like a whole separate thing that companies would do to protect

- generalizations 5y agoCan confirm. Look at the FCC regulations for selling rf-emitting devices. The seller has to show that the device will only emit at the specified frequencies and power. When it's consumer-facing, like a wifi router, one way to do that when the hardware itself is technically capable of more, is to lock down the firmware. The downvotes on gp are misinformed.
- monocasa 5y agoThese chips and their closed blobs are older than the relevant FCC regulation.
- aksss 5y agoHasn’t the relevant fcc regulation (concerning signal strength and use) been around since the eighties at least?
- monocasa 5y agoIt was a 2015 ruling that can be seen as not allowing user modifiable firmware for transmitter hardware. https://www.wired.com/2016/03/way-go-fcc-now-manufacturers-locking-routers/ https://www.wired.com/2016/03/way-go-fcc-now-manufacturers-l...
