Wireless Repeater
Triple-band wireless repeater can amplify two bands or multiple sub-bands signals at the same time by sharing one antenna feeder system. It is a good solution for multi-operator coverage projects because the infrastructure costs will be greatly reduced.
In the downlink path, the repeater will pick up the signal from the exiting transmitter via the donor antenna, amplifying and re-transmitting it into the desired coverage area via the service antenna. In the uplink path, the repeater will receive signals from cell phones in the covered area and re-transmit them back to the base station.
