Final answer:
Network analyzers or packet sniffers are used to collect wireless packet data, which can enable law enforcement or criminals to track cell phones and even remotely access their microphones and cameras.
Step-by-step explanation:
The program that collects wireless packet data is typically referred to as a network analyzer or a packet sniffer. This software monitors and captures data packets that are transmitted over a wireless network. Law enforcement and, unfortunately, criminals can use sophisticated versions of these tools to identify and track cell phones. With the right software, they can even remotely activate a phone's microphone and camera, effectively using the device to eavesdrop on the owner. This highlights the importance of understanding network security and being aware of the potential privacy risks associated with wireless communications.
