Appendix Y: Location (FTP) Tests
Introduction
The Location, or FTP, Test is performed to check the Ripwave system operation through file
transfers between the Base Station and the Modem. The test measures the data rate performance
at various locations within the coverage area. Data throughput is measured by executing file
transfers using the FTP protocol for both upstream and downstream links. A file server must be
in place on the same subnet with the BTS to accurately perform the file transfer, and the CPE
User computer must be loaded with an FTP Client. As the file transfer is running, a data file is
captured by the Modem tool. Data rates are captured by the FTP program.
Data is recorded in a spreadsheet format. The spreadsheet lists the location, GPS, and other
information. As data rates are captured, the results are entered manually. An average SNR and
sync RSSI can be read from the debug tool, and recorded, for quick comparison to the acceptable
criteria (see “Acceptable Criteria” section of this appendix). For NLOS indoor locations, tests are
performed both outside the building and inside, so that the obstruction loss for the building can
be determined. Unless the customer can provide indoor access, all results will be LOS or Near
NLOS.
Planning the Locations
Before the actual testing is conducted, you will need to select the locations for the testing to
occur. The sites should meet specific criteria and include a mixture of the following
environments:
?? High Power (A), low clutter; close in, residential
?? High Power (A), high clutter; close in, commercial
?? Medium Power (B), low clutter; mid-range, residential
?? Medium Power (B), high clutter; mid-range, commercial
?? Low Power (C), low clutter; distant, residential
?? Lower Power (C), high clutter; distant, commercial
Where:
(A) High Power = Sync Value greater than –70 dBm
(B) Medium Power = Sync Value between –70 dBm and –85 dBm
(C) Low Power = Sync Value between –85 dBm, and –95 dBm
