Wireless communication auxiliaries

Power Line Amp
  • Power Line Amp (PLA) and the Filtering and amplifying the signals to the proper signal of the lower 400 MHz and FM so you can extend the line will be installed to service the shaded area of the building
  • In the underground and ground floor and Power Line Amp is designed to enable wireless communication between the transceiver in the different layers, it can be obtained a superior radio link quality
Line Amp

Installation to compensate for line loss of the coaxial cable to be installed in the propagation shadow area, and a unit that was by lengthening the length of the cable loss occurs is transmitted as the output of the constant Level for the purpose of long-distance transmission to be impossible to transmit the distance.
