Import 20dbm Single Band Gsm Mobile Signal Repeater — Buy in Bulk from Supplier in China

The 20dBm Single Band GSM Mobile Signal Repeater is a radio frequency amplification device designed to capture existing weak cellular signals from outside antennas and rebroadcast them indoors with increased power. This specific model operates at 20 decibel-milliwatts output, which classifies it as a medium-power repeater suitable for residential and small office environments. The device works on GSM frequency bands typically spanning 850MHz or 900MHz depending on regional network allocations, and it amplifies both voice and 2G data signals. Key specifications include a coverage area rating for small to medium spaces, which generally translates to approximately 500-2000 square feet depending on building construction materials and original signal strength. The unit features automatic gain control to prevent signal overload and maintains a flat gain response across the operating frequency band.

The repeater housing is constructed from aluminum alloy with heat dissipation features to manage thermal output during continuous operation. The device includes built-in safeguards against signal overload, which protects both the unit and connected mobile devices from interference. Typical frequency tolerance for GSM band repeaters is within plus or minus 200kHz of the designated carrier frequency. The input sensitivity rating typically requires a minimum received signal strength of -90dBm or stronger from the external donor antenna to achieve effective amplification. Internal components include a low-noise amplifier, bandpass filtering to prevent out-of-band emissions, and a power amplifier stage. The unit operates on standard 100-240V AC power input with DC regulation providing stable 12V or 24V internal operation.

This repeater is purchased by telecommunications resellers, building contractors installing distributed antenna systems, and facility managers addressing dead zones in office buildings, warehouses, and residential complexes. Buyers typically require MOQ flexibility for stocking and distribution, and the product is offered with FOB and CIF shipping terms. The target buyers include signal solution integrators, IT infrastructure companies, and retail distributors specializing in connectivity equipment. Quality certification documentation should be verified before purchase, and buyers should confirm compatibility with their specific regional GSM frequency allocations.
