The discussion centers around the impact of 5G technology on IMSI catchers, with a consensus that while criminal use of IMSI catchers may be declining, law enforcement retains methods for tracking individuals through the capabilities of 5G networks. 5G's enhanced features, such as mmWave and beamforming, allow for precise location tracking, often making IMSI catchers redundant. Although IMSI catchers were previously useful for gathering identifiers and personal information, their necessity may be lessened due to the extensive surveillance capabilities provided to carriers. Additionally, there are inquiries into potential SIM card configurations that could enhance privacy by preventing connections to certain network technologies, suggesting ongoing concerns about network security and individual privacy.
