2.2.2 Downlink/ Uplink Path

The user may select frequency bands according to the site conditions. After receiving a signal from the donor antenna(s), the repeater improves it and sends a securely isolated signal out to the service antenna(s). Each amplifier module has its own separate digital filter module (DFM). The amplifier module consists of a down converter, up converters, cavity filter, and power amplifier (PAU). In the Downlink Path:

1. RF Signal is received from the donor antenna through the input port.

2. The signal is then converted from RF to IF,

3. The IF signal is digitized by the DA converter,

4. The digital signal is filtered by the DFM (FPGA),

5. The modulator converts the digital signal to an analog RF signal and transmits to the amplifier.

6. Amplifier outputs final signal to service antennas at desired output power.

Uplink path works in reverse order.

3.1.1 Check points before turning on the Repeater

1) System Power Check: AC electrical power to the repeater should be 110V. Input electricity only after power verification.

2) Input RF Signal Range: Optimal input RSSI into the repeater is -57dBm ~ -27dBm for

700MHz/850MHz/1900MHz/2100MHz. User should verify input condition of Donor ANT. If the input RSSI exceeds -27dBm, then external attenuators should be added.

3) Isolation check between DONOR/SERVER ANT: Isolation condition of this equipment is

105dBc (Gain+15dB). The User should check this condition before installation.

3.4 Troubleshooting

In case of abnormal operation, technician should diagnose abnormality via remote access or directly connecting to repeater using Ethernet cable. If technician is required to conduct repairs due to major alarm, repeater should first be powered off, and then technician should prepare the proper measurement equipment before trying to fix the problem.

3.4.1 Simple Troubleshooting Method

1) Verify LED Status, both on external LED’s as well as internal module LED’s

- Normal operation: Green light on. Alarming: Red LED on.

2) Technician should check external and internal connectors to ensure all connections are tightly secure. These connectors should be cleaned regularly.

3) If technician thinks there is a serious problem, call technical support. 1-866-9-GST-USA (1-866-947-8872)
