| Popis: | This paper presents a new method for jamming of GSM communications. The aim is to decrease voice connection quality, thus disabling users to understand each other, while keeping established connections. The jamming method parameters depend on the algorithm characteristics implemented in SACCH frame. It is proved for three mobile telephony codecs that it is possible to reach unsatisfactory voice connection quality MOS less than 2 due to jamming of a GSM communications channel. Errors in data transmission during the periods without jamming also cause voice connection quality impairment and this influence is analyzed. The method performances are compared to other solutions. |
