What is the frequency range of RTL-SDR?
The RTL-SDR is a USB dongle that can be deployed as an RF-frontend as shown in Figure 3.1 a). It operates at the frequency range of 24-1766 MHz [55] , therefore, it is an ideal candidate for the LPWAN technologies that operate in the sub-1 GHz frequency band.
What is RTL-SDR sample rate?
The maximum sample rate is 3.2 MS/s (mega samples per second). However, the RTL-SDR is unstable at this rate and may drop samples. The maximum sample rate that does not drop samples is 2.56 MS/s, however some people have had luck with 2.8MS/s and 3.2 MS/s working well on some USB 3.0 ports.
What does RTL-SDR stand for?
RTL is short for RTL2832U. The Realtek RTL2832U chipset was a popular choice for digital video broadcast (DVB-T) receivers, whose original purpose was to receive video. It was discovered that these could be hacked and turned into wideband SDR receivers. These devices have come to be known as the RTL-SDR.
