Navini Networks, Inc. Ripwave Base Station I&C Guide 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.
Ripwave Base Station I&C Guide Navini Networks, Inc. At least 5 test points for each type are attempted. This may be difficult, depending upon the actual deployment scenario. Results may yield a very large percentage in one of the categories. For selecting an even spread across a 120-degree sector for a panel antenna installation, divide the 120 degrees into 6 even slices of 20 degrees each. Then divide each slice into 2 Km segments.
