Openwifi: Linux mac80211 compatible full-stack 802.11/Wi-Fi design based on SDR
It seems one of the final missing links to fully open source hardware WiFi would be the RF transceiver chip. This is, to my understanding, something similar to a high-bandwidth DAC and ADC coupled with configurable frequency mixers to access radio frequencies.<p>Is anyone trying to create an open source version of that chip? I understand there's not a lot in the way of open source analog chip designs out there, but with Google/Skywater's free PDK, the time may be ripe to change that.<p>Also, there are many SDR LTE base stations, but can we make our own SDR LTE handset as well? Can it connect to an existing cell network?
