Explanation
A cell tower analyzer (also known as a network signal analyzer or IMSI catcher detector) can identify the cellular tower the phone is connecting to and verify its legitimacy, including the tower ID, carrier information, and location data. A sudden, unexplained jump to full signal strength could indicate a rogue cell tower (such as an IMSI catcher or 'stingray') attempting to intercept communications by spoofing a legitimate carrier tower. A WiFi analyzer (A) only examines 802.11 wireless networks, not cellular. A spectrum analyzer (C) measures raw RF frequencies but cannot identify cell tower identity. A packet analyzer (D) captures network traffic but cannot verify cellular tower legitimacy.
