w1700k-sdr projekti on valmistanud p\u00fcsivara ja utiliitide kogumi, mis muudab Gemtek W1700K Wi-Fi 7 traadita ruuterist programmeeritava raadiotehnika (SDR), mis suudab vastu v\u00f5tta ja anal\u00fc\u00fcsida raadiolainete signaale laias sagedusvahemikus. Kood on kirjutatud C ja Python keeltes ning jagatakse MIT litsentsi alusel, v\u00e4lja arvatud tuumamoodul, mis on antud GPLv2 alusel.<\/p>\n

Ruuteris rakendatav SoC Airoha AN7581 on kasutusel raadiokiibi poolt saadud andmete esmasteks t\u00f6\u00f6tlemiseks ja nende edastamiseks v\u00e4lisele arvutile, mis on \u00fchendatud 10-gigabitise Etherneti kaudu UDP-s, kiirusel kuni 320 miljonit valimit sekundis (Msps). Arvutis anal\u00fc\u00fcsitakse ja visualiseeritakse andmeid graafikute ja spektrite abil.<\/p>\n

P\u00fcsivara on loodud nullist, ilma MediaTek'i omandi\u00f5igusega koodi kasutamiseta, kuid kasutades mt76 draiverist saadud koodi, mis on antud BSD litsentsi alusel. P\u00fcsivara initsialiseerib raadiokiibi iseseisvalt ja juhib seda hostilt saadetavate k\u00e4skude kaudu. K\u00f5vakettas kanalitele on kehtestatud v\u00f5imalus seadistada heterod\u00fcnaator mis tahes sagedusele sagedusvahemikes 2.081-2.748 GHz, 4.647-7.509 GHz ja 4.707-7.576 GHz sammuga 2.98 Hz v\u00f5i 11.9 Hz. Sagedust saab muuta reaalajas umbes 1 ms latentsusega. <\/p>\n
