Il progetto w1700k-sdr ha sviluppato un firmware e un insieme di utility che trasformano il router wireless Gemtek W1700K Wi-Fi 7 in un sistema radio definito dal software (SDR), capace di ricevere e analizzare segnali radio su un ampio intervallo di frequenze. Il codice \u00e8 scritto in C e Python e distribuito con licenza MIT, ad eccezione del modulo del kernel fornito sotto GPLv2.<\/p>\n

Dopo la sostituzione del firmware standard, w1700k-sdr riprogramma il chip radio MediaTek MT7996 per catturare segnali radio arbitrari, non limitati ai canali Wi-Fi. Il SoC Airoha AN7581 utilizzato nel router \u00e8 impiegato per il preprocessamento dei dati dal chip radio e per inviarli a un computer esterno collegato tramite Ethernet a 10 gigabit via UDP, con una velocit\u00e0 fino a 320 milioni di campioni al secondo (Msps). Sul computer, i dati vengono analizzati e visualizzati tramite grafici e spettrogrammi.<\/p>\n

Il firmware \u00e8 stato creato da zero senza utilizzare codice proprietario MediaTek, ma utilizzando codice dal driver mt76, fornito con licenza BSD. Il firmware inizializza autonomamente il chip radio e lo gestisce tramite comandi dal host. Invece di un legame rigido ai canali, \u00e8 stata implementata la possibilit\u00e0 di sintonizzare il generatore di segnale su qualsiasi frequenza nelle gamme 2.081-2.748 GHz, 4.647-7.509 GHz e 4.707-7.576 GHz con passi di 2.98 Hz o 11.9 Hz. La frequenza pu\u00f2 essere cambiata al volo con un ritardo di circa 1 ms. <\/p>\n
