Proiectul w1700k-sdr a preg\u0103tit un firmware \u0219i un set de unelte care transform\u0103 routerul wireless Gemtek W1700K Wi-Fi 7 \u00eentr-un sistem radio definit prin software (SDR), capabil s\u0103 primeasc\u0103 \u0219i s\u0103 analizeze semnalele radio pe o gam\u0103 larg\u0103 de frecven\u021be. Codul este scris \u00een limbaje C \u0219i Python \u0219i este distribuit sub licen\u021ba MIT, cu excep\u021bia modulului kernel, furnizat sub GPLv2.<\/p>\n

Dup\u0103 \u00eenlocuirea firmware-ului standard, w1700k-sdr reconfigureaz\u0103 chipul radio MediaTek MT7996 pentru a capta semnale radio arbitrare, f\u0103r\u0103 a fi limitat la canalele Wi-Fi. SoC-ul Airoha AN7581 utilizat \u00een router este activat pentru prelucrarea ini\u021bial\u0103 a datelor de la chipul radio \u0219i trimiterea acestora pe un computer extern, conectat prin Ethernet de 10 Gigabi\u021bi prin UDP, cu o vitez\u0103 de p\u00e2n\u0103 la 320 milioane de e\u0219antioane pe secund\u0103 (Msps). Pe computer, datele sunt analizate \u0219i vizualizate prin grafice \u0219i spectrograme.<\/p>\n

Firmware-ul este creat de la zero, f\u0103r\u0103 utilizarea codului proprietar MediaTek, dar cu utilizarea codului din driverul mt76, furnizat sub licen\u021ba BSD. Firmware-ul ini\u021bializeaz\u0103 autonom chipul radio \u0219i \u00eel controleaz\u0103 prin comenzi de pe host. \u00cen loc de o leg\u0103tur\u0103 rigid\u0103 la canale, este implementat\u0103 posibilitatea de a seta heterodina pe orice frecven\u021b\u0103 \u00een intervalele 2.081-2.748 GHz, 4.647-7.509 GHz \u0219i 4.707-7.576 GHz, cu un pas de 2.98 Hz sau 11.9 Hz. Frecven\u021ba poate fi schimbat\u0103 \u00een timp real cu o \u00eent\u00e2rziere de aproximativ 1 ms. <\/p>\n
