Import All Gsm Cdma 3g 4g Wifi Gps Lojack Signal Jammer — Buy in wholesale FOB from Supplier in China

Jammer Group offers an adjustable ten-band signal jammer covering CDMA 850-894 MHz, GSM 920-960 MHz, DCS 1800-1880 MHz, PCS 1920-1990 MHz, 3G 2100-2180 MHz, WiFi 2400-2480 MHz, 4G LTE, 4G Wimax, GPS L1 1575.42 MHz, and Lojack 167-173 MHz. The device delivers 24W total output power through eight external omni-directional antennas, with an adjustable frequency control allowing selective band activation. Jamming range extends up to 50 metres depending on local signal strength and environmental conditions. The unit measures 330 by 238 by 65 millimetres and weighs 6.0 kilograms, powered by AC 110-250V with an external 12VDC 15A supply included.

The ten-band architecture targets cellular voice and data, wireless local area network, satellite navigation, and vehicle tracking frequencies. CDMA and GSM bands cover legacy and current 2G cellular infrastructure, while DCS and PCS address 1800 and 1900 MHz cellular allocations. The 3G band at 2100-2180 MHz targets UMTS networks, and 4G LTE/Wimax coverage is switchable between US and European frequency allocations. GPS L1 jamming at 1575.42 MHz interferes with civilian satellite navigation receivers, while Lojack coverage at 167-173 MHz targets vehicle recovery systems. WiFi suppression at 2.4 GHz affects IEEE 802.11b/g/n devices in the immediate vicinity. The adjustable button interface permits users to activate specific bands rather than blanket jamming, reducing power consumption and detection risk.

Typical applications include security installations, examination halls, correctional facilities, and meeting rooms where unauthorised wireless communication or tracking is prohibited. The device is not frequency-agile beyond the preset bands, so emerging 5G NR networks and 5.8 GHz WiFi are not affected. Buyers should confirm local regulatory status before import, as signal jamming devices are restricted or prohibited in many jurisdictions including the European Union, United States, Canada, Australia, and numerous Asian markets. The cooling system is designed for continuous 24/7 operation. Packaging and shipping from Shenzhen typically involves standard export cartons, with power cord adapted to destination voltage if specified.

Jammer Group is located at Fuhuaraod, Shenzhen 518000, Guangdong Province, China. The supplier operates under an imported tier classification with harbor trust tier status. The response rate is recorded at 0.00 percent with zero average response hours, indicating no platform-mediated communication history is available for prospective buyers to evaluate. The supplier's profile on the marketplace is limited to the single product listing described here, with no additional company history, certification, or client reference information provided.

The source description presents product technical details without organisational background, manufacturing credentials, or export experience. No ISO registration, factory audit results, or intellectual property ownership is stated. Buyers should conduct independent verification of the supplier's legal entity registration, manufacturing location, and compliance with Chinese regulations for radio transmitting equipment production. The address format in the source data contains apparent typographical irregularities, so confirming current contact details directly with the supplier is essential before any commercial engagement.
