Performance comparison of mobile phone signal jammers: Who is the real "signal terminator"?
Shielding range: The coverage range of different cell phone signal jammers varies significantly. High-end devices can cover hundreds of meters and are suitable for large venues; low-end devices are only suitable for small areas, such as conference rooms or classrooms.
Frequency coverage: Superior signal blockers can block signals in multiple frequency bands, including 2G, 3G, 4G, 5G and Wi-Fi, ensuring comprehensive shielding; while weaker devices may only support some frequency bands and have limited shielding effects.
Power and stability: High-power signal jammers are more stable in complex environments and can effectively penetrate obstacles such as walls; low-power devices may fail when there are more obstacles.
Heat dissipation and durability: High-quality signal blockers usually have good heat dissipation design and are suitable for long-term operation; low-end devices may overheat due to poor heat dissipation, affecting their service life.
Price and cost-effectiveness: High-end signal jammers are expensive but have excellent performance; low-end devices are cheap but have poor performance and stability. When choosing, you need to weigh your needs and budget.
A true "signal terminator" should have wide coverage, multi-band support, high power output, good heat dissipation and reasonable price.
