Feature: 1. Dormant GPS physical detection can be error‑free, high accuracy and high‑sensitivity. Smart chip can make the product can detect about 10 meters without interference and can detect wireless devices between 1MHz‑6.5GHz frequency. 2. It uses dual antenna design dual‑frequency and can promote the performance, which can automatically switch frequency bands. High‑gain antenna, combined with radio wave can search signal faster, unlock azimuth and detect distance more accurately with stronger anti‑interference. 3. 1Mhz‑8000Mhz full‑band high‑gain antenna will have more urgent alarm sound, if it is closer to the suspicious signal. T8000 is the most advanced portable wireless signal detection equipment, especially suitable for special processing of CDMA signals. 4. You can use for Telecom's mobile phones to make calls and test the sensitivity of the detector. In addition, the transmission power of the CDMA card is very small, and it is not easy to be detected by traditional wireless detectors, but the signal detector can be the perfect replacement. 5. You can detect that if there is wireless error or location tracker installed in the car or office, and if there are suspicious signals around, if there is radiation in your working place, the roof of residential buildings, and household appliances such as microwave ovens are waiting for leakage that is harmful to the human body of electromagnetic radiation. 6. You can know that if your phone is normal (transmitting signals for no reason in the standby state), detect wireless network signal, mobile phone signal, wireless monitoring system, check if there is suspicious wireless signal in hotels, restrooms, hotels, entertainment venues, business negotiations, and locker rooms.
