Traditional radios work by having electronic circuitry that tunes in only the frequency of interest. The hardware of the radio uses filters and other technologies to modify the signal so that only the desired wave is output. Circuits take care of splitting left and right stereo signals, filtering out side bands, receiving AM or FM, etc.; they ultimately ...

is it really possible to sniff all packets from all devices connected to a router using a sniffing software like Wireshark? The answer is yes. But the scenario must meet certain requisites (that you can someway force). Wireshark will display any packet of any protocol as long as it can “see” them and while they are in the same environment (with some ...

As said by @stuchl4n3k, HackRF One is a SDR (Software Defined Radio) solution. This mean that the whole "protocol" part is done on software side. The advantages of such a solution is that it isn't limited to one usage: with HackRF One, one may create: GSM / LTE base station. 433 Mhz (garage door) sniffer/emitter. DAB+ (Digital Audio Broadcast) receiver. ...

From sniffing POV, HackRF One as well as many other SDRs give you radio wave processing capabilities. This means that you can tune to a wide band of frequencies and capture the signal. What you do with it then is generally beyond the SDR's scope. You can always try to process the signal yourself (e.g. with GnuRadio) and write a decoder the data packets for ...
