Perform Calibration Using Customer’s EMS
This step is necessary only if you have been using a Test EMS up to this point. You will need to
install the customer’s EMS server and software. Calibrate the Base Station using the customer’s
EMS. Follow the same calibration procedures described earlier in this chapter, Calibrate the Base
Station. Perform the procedure three times and make sure that the results are stable (+/–3).
Verify System Performance
Drive Study
The preliminary Drive Study is performed if no RF coverage model is available. The Drive
Study helps you to map out the coverage area. Later, the full Drive Study is performed to see if
the system’s coverage area is as predicted and, if necessary, to fine-tune the RF model.
Following the detailed Drive Study procedures in Appendix X, you will perform a preliminary
Drive Study by driving back and forth through a sector, staying on major roads about a kilometer
apart. Special attention has to be paid to the null and fringe areas. You will follow this scheme
for each sector in the site, recording the results of all tests. The test results will be sent for
evaluation, along with the Location (FTP) test results, to Navini Networks Technical Support. If
the results are not adequate, Technical Support will have you adjust some of the RF parameters
and perform the Drive Study again.
Location (FTP) Test
Location Tests are performed to see if the system file transfer functions are working as predicted
between CPE and Base Station. These are conducted in stages as well. The first stage is the
preliminary Location Test, where you perform three uploads and three downloads at three
locations with the Base Station in line-of-sight (LOS). Then you perform three uploads and three
downloads at three locations with the Base Station in non-line-of-sight (NLOS). For the NLOS
testing, you will need to find an obstacle, such as a building, between the CPE and Base Station.
Results are sent, along with the preliminary Drive Study results, to Navini Networks Technical
Support for evaluation. If the results are not adequate - i.e., file transfers do not meet customer’s
objectives - Technical Support will have you adjust some of the RF parameters and perform the
Location tests again. The detailed Location Test procedures and form are located in Appendix Y.
To summarize, these are the high-level steps for verifying system performance:
1. Conduct preliminary Drive Study (if no RF coverage map is available).
2. Conduct preliminary LOS Location Tests.
3. Conduct preliminary NLOS Location Tests.
