TESLA GSM-LTE Signal Booster/Repeater for Improved Cell Phone Reception

The TESLA GSM-LTE Signal Booster/Repeater offers a reliable solution for homes, offices, or recreational facilities with weak or unstable mobile signals. It allows you to stay connected even in areas with poor signal strength. Installation is easy—simply connect the device to an outdoor antenna, which captures the available signal and transmits it for further processing. The signal is then distributed throughout the surrounding area at a quality corresponding to the reception at the outdoor antenna.

The device operates in the GSM 900 MHz and LTE 1800 MHz frequency bands. The former is used for standard two-way calls over the mobile network, while the latter provides access to high-speed data connections.

The signal booster/repeater is designed to work seamlessly with mobile networks available in the Czech Republic*.

Main functions and features:

• Amplifies/repeats the mobile signal in the GSM 900 MHz and LTE 1800 MHz frequency bands
• Provides two-way voice communication in the GSM 900 MHz band
• Supports high-speed data connections in the LTE 1800 MHz band
• Automatic gain control (AGC), AI-powered power-saving mode
• The resulting signal quality corresponds to the signal level at the outdoor antenna
• Receiving voice calls over LTE is not supported
• 900/1800 MHz signal availability may vary depending on coverage and carrier*
• Coverage up to 500 m²
• Easy installation without the need for professional assistance
• Complete installation kit included in the package
• Robust aluminum housing ensures efficient cooling and a long service life
• Device status and operation indicators
• CE and RoHS certified—safe and environmentally friendly operation
