Various sensing and signal detection components form the "perception and diagnosis system" of the communication terminal, enabling precise collection of signal strength, environmental parameters, and equipment operating status. This includes radio frequency sensors, signal detection chips, light sensors, distance sensors, acceleration sensors, positioning sensors (GPS/Beidou), and battery status sensors, etc. With high sensitivity and low power consumption, it can support functions such as signal strength detection of the communication terminal, intelligent signal optimization, precise positioning navigation, call noise reduction, and equipment abnormal warning (such as overheating of the battery, signal interference), providing data support for stable communication and safe operation of the equipment.
