1. Interference frequency band: Mobile phone signal jammers can cover a wide range of communication frequency bands, including 2G, 3G, 4G, 5G and other mobile communication network frequency bands to ensure comprehensive interference to various mobile phone signals.
2. Interference power: The interference power of mobile phone signal jammer is one of the important indicators to measure its performance. In general, the greater the interference power, the wider the interference range, but also need to consider the impact on the surrounding environment and human health. Therefore, the mobile phone signal jammer usually has an adjustable interference power to adapt to the needs of different occasions.
3. Interference range: The interference range of the mobile phone signal jammer depends on its interference power and the influence of the surrounding environment. In general, the mobile phone signal jammer can form an effective interference area within a certain range to ensure that the mobile phone signal in the area cannot be used normally.

4. Stability: The mobile phone signal jammer needs to run steadily for a long time to ensure its reliability. Therefore, mobile phone signal jammers usually use advanced thermal design and stable power supply to ensure that they can work stably in a variety of environments.
5. Safety: Mobile phone signal jammers need to comply with relevant safety standards and regulations to ensure that their use will not cause adverse effects on the surrounding environment and human health. Cell phone jammers are typically designed with low radiation to reduce interference with the surrounding environment.
