Projekt w1700k-sdr opracowa\u0142 oprogramowanie i zestaw narz\u0119dzi, kt\u00f3re przekszta\u0142caj\u0105 bezprzewodowy router Gemtek W1700K Wi-Fi 7 w system radiowy definiowany programowo (SDR), zdolny do odbierania i analizowania sygna\u0142\u00f3w radiowych w szerokim zakresie cz\u0119stotliwo\u015bci. Kod jest napisany w j\u0119zykach C i Python i jest rozpowszechniany na zasadach licencji MIT, z wyj\u0105tkiem modu\u0142u j\u0105dra, kt\u00f3ry jest dostarczany na licencji GPLv2.<\/p>\n

Po wymianie podstawowego oprogramowania w1700k-sdr przprogramowuje chip radiowy MediaTek MT7996 do przechwytywania dowolnych sygna\u0142\u00f3w radiowych, bez ogranicze\u0144 kana\u0142ami Wi-Fi. Zastosowany w routerze SoC Airoha AN7581 jest wykorzystywany do wst\u0119pnego przetwarzania danych z chipa radiowego i ich przesy\u0142ania na zewn\u0119trzny komputer pod\u0142\u0105czony przez 10-gigabitowy Ethernet za pomoc\u0105 UDP, z pr\u0119dko\u015bci\u0105 do 320 milion\u00f3w pr\u00f3bek na sekund\u0119 (Msps). Na komputerze dane s\u0105 analizowane i wizualizowane za pomoc\u0105 wykres\u00f3w i spektrogram\u00f3w.<\/p>\n

Oprogramowanie zosta\u0142o stworzone od podstaw, bez u\u017cycia w\u0142asno\u015bciowego kodu MediaTek, ale z wykorzystaniem kodu z sterownika mt76, kt\u00f3ry jest dostarczany na zasadach licencji BSD. Oprogramowanie samo inicjalizuje chip radiowy i zarz\u0105dza nim za pomoc\u0105 polece\u0144 z hosta. Zamiast sztywnego wi\u0105zania z kana\u0142ami, zaimplementowano mo\u017cliwo\u015b\u0107 dostosowania heterodyny do dowolnej cz\u0119stotliwo\u015bci w zakresach 2,081-2,748 GHz, 4,647-7,509 GHz i 4,707-7,576 GHz z krokiem 2,98 Hz lub 11,9 Hz. Cz\u0119stotliwo\u015b\u0107 mo\u017ce by\u0107 zmieniana w locie z op\u00f3\u017anieniem oko\u0142o 1 ms. <\/p>\n
