11.5 Remote Unit Configuration
The remote unit will automatically receive all the configuration data from the monitoring system. The
remote unit will not start transmitting before receiving acknowledgment from the monitoring system
that the parameters loaded into its memory are valid.
In the case of a power down, once power restored the remote unit will wait 1 minute before starting to
transmit with its initial configuration parameters.
11.6 Normal Operation
The remote unit LED should be green.
11.7 Recommended Measurements
11.7.1 Testing the First Remote Units
It is advised to perform the following measurements for the first few remote units installed in the
network to verify proper operation:
1. Measure signal levels at the coax cable connection between the wall outlet and the remote unit.
The pilot and the cellular signals should be visible at levels between -20 dBm to – 50 dBm
(dependant of the coax length in this specific network branch)
2. In case a remote unit with external RF outputs is available, measure that the output power is 10
dBm (as specified) and the RF output is at the correct cellular frequency
11.7.2 Standard Remote Unit Testing
For all remote units perform the following:
1. After installing the remote unit, verify the LED is green
Using dedicated cellular test equipment (Handset with test mode or specialized h/w)
2. Measure the cellular downlink signal.
3. Generate a call and test: coverage quality (walk test), call quality and uplink transmit power
4. In case there is a problem perform the measurements in section 9.7.1 for further troubleshooting
12 Preparing for Remote Unit Installation
All operation and maintenance actions are done through the monitoring system. The monitoring
system is a web based application residing on a local PC which serves as a web server.
12.1 Logging into the Monitoring System
Upon activation of the system, the user will be directed to the entry screen and prompted to enter User
Name and User Password. Enter the login information to enter the system.
