Appendix H: 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 CPE. 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 CPE 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 is equal to > -70 dBm sync value

(B) Medium Power is equal to < -70 dBm and > -85 dBm sync value
