Detailed Product Description

Our Mini Repeater (i.e. small RF repeater with output power lower than 1W) provides an affordable solution to solve the indoor coverage problems due to signal fading and attenuation caused by architecture obstacles.

It is mainly deployed for small points of in-building wireless signal coverage, when installation of standard repeaters will generate great interference to the wireless network or the area to be covered is widely distributed. Its easy installation and maintenance can help carrier get fast return.

The Mini Repeater works as a relay between the BTS and mobiles. It picks up the strongest signal from the BTS via the Donor Antenna, linearly amplifies the signal and then retransmits it via the Coverage Antenna to the weak/blind coverage area. And the mobile signal is also amplified and retransmitted to the BTS via the opposite direction.

Application Diagram of Mini Repeater

To expand signal coverage or fill signal blind area where signal is weak or unavailable.

Use the brackets to mount the mini repeater onto a wall.

Use the AC/DC adaptor to give power supply to the mini repeater.

The user manual gives you a complete guide for the installation, operation and troubleshooting of the mini repeater.

Optional Accessories

Use the jumper cables to connect the mini repeater to the Donor Antenna and the Coverage Antenna.

The Donor Antenna is used to pick up wireless signal from the BTS. It connects to mini repeater via a jumper cable. Usually it is installed outdoors (e.g. on the roof) to get better signal.

The Coverage Antenna helps to transmit the amplified signal to the area to be covered. A jumper cable is also required to connect it to the mini repeater.

Use the cable ties to fix the jumper cables.

Wrap the waterproof tape over the joint of RF connectors to give protection against rain and humidity.
