GSM Pojačalo / Repeater GSM signala – 2G/3G/4G Voice + Data.




The Signal GDW-505 repeater amplifies EGSM,GSM,DCS, WCDMA, LTE signals inside buildings. The device is ideal for locations where the range of a cellular network allows for use of mobile phones out of buildings, but is insufficient for indoor operation. An example may be a place located far from the transmitter or a building with thick walls, cellars (coffee shops) or modern windows with panes of covered with metallic compounds.
The GDW-505 repeater is a consumer device that amplifies the full range of GSM/EGSM/DCS/WCDMA signals (LTE in the 900, 1800, 2100 MHz band), meets the requirements of the RED Directive 2014/53/EU and the ETSI standards 303 609. The device has a CE declaration.

Contents of the set:
  • repeater,
  • wall plugs and bolt,
  • manual
This product can solve the problem of low GSM/3G/LTE signal in hotels, boardinghouses, and various buildings, allowing to use cellular phones for calls and Internet access.
AGC function. Automatic gain controls the gain up to 20 dBm, which means that if the signal at the input of the device is too high, an appropriate mechanism will “suppress” it.
Controlled gain: This function allows you to manually set the signal strength at the output to adjust it to the value allowed by the repeater.
nstallation of the Signal GDW-505 repeater:
  • find a place outside the building where we the GSM signal is received,
  • mount the outdoor antenna (A741031) so that it faces the GSM base station,
  • choose a location for installing the repeater somewhere inside the building to place the indoor antenna in the central part of the building/hall/room to be covered,
  • check if the distance between the outdoor and indoor antennas is at least 10 m,
  • install the GDW-505 repeater away from heat sources, ensuring proper device cooling,
  • check the cables for proper connection to the antenna and the amplifier
  • (external and internal antenna sockets are marked respectively),

  • plug the power supply into the 230 VAC socket
The Signal GDW-505 repeater connects to both, the external and internal antenna with cables, so it is easy to choose an installation location where 230 VAC is required.
