Handheld cell phone detector - CIU Co., Ltd.
We are in a Noisy World! Speaking at the same loudness, we barely can hear conversation from the person in front of us in a restaurant, or in a subway station. However, we can hear people's murmuring from a far distance in suburb. This is because the sound noise level in a subway station is much higher than in the suburb.
Similarly, Our World is also contaminated by Radio Frequency emissions. RF Noise is everywhere. The degree of contamination varies with respect to time, location, and frequency.
4G LTE cell phone detector can only capture the signal above the noise floor. In cellphone frequency bands, the noise level is strongly related to the distribution of base stations.
At the same location, the power transmitted from a cell phone is dependent with the location of the base stations. To reach a farther base station, it will need higher power.
Sensitivity means the lowest signal level can be detected (distinguishable from Noise)
All Sensitivity Adjustment
After sensitivity of each frequency band is optimized, we can use device control buttons or remote connection to adjust the overall sensitivity.

Summary:
- Detectable distance is location and frequency band dependent (Noise level).
- It requires patience to optimize the system.
- After tuning each band, over all sensitivity can be adjusted remotely.
- Maximum detection distance has no absolute value. It is affected by the cell phone user and the location of base station.
- The farther from the base station, the longer is the detection distance.
