  Currently, most mobile phone signal jammers on the market are full-band interference devices that can effectively shield mainstream communication and wireless network frequencies and adapt to various complex environmental requirements. Its main shielded frequency bands include:

  Mobile communication frequency band

  CDMA: 867–885 MHz (China Telecom 2G)

  GSM: 923–960 MHz (China Mobile/China Unicom 2G)

  DCS/4G: 1805–1990 MHz (part of 4G frequency band)

  3G (China Unicom/China Telecom): 2100–2175 MHz

  Mobile 3G (TD-SCDMA): 2008–2029 MHz

  4G FDD-LTE:

  4G1: 2298–2406 MHz

  4G2: 2547–2650 MHz

  

  Wireless network frequency band

  WiFi 2.4GHz: 2400–2485 MHz

  WiFi 5.1GHz: 5150–5350 MHz

  WiFi 5.8GHz: 5725–5825 MHz

  5G frequency band (Sub-6GHz)

  5G N78 frequency band: 3400–3600 MHz

  5G N79 frequency band: 4800–4900 MHz

  Product advantages overview

  Full-frequency coverage: supports shielding of current mainstream communication formats, including 2G, 3G, 4G, 5G and WiFi networks.

  High-performance interference: using advanced circuit design and frequency band layered interference, signal shielding has no dead angle.

  Cooling system optimization: equipped with high-efficiency air cooling or aluminum alloy cooling module, supports long-term stable operation.

  Plug and play: installation-free design, easy operation, can be used after power on.

  Safe and reliable: will not interfere with other electronic devices, no radiation damage to the human body.

  Applicable places: school examination rooms, conference rooms, prisons, detention centers, military strongholds, government agencies, libraries, theaters, gas stations and other environments where mobile communications and wireless networks need to be restricted or shielded.
