North Queens TV White Space Trials
Results from 2nd Test Site
The test site is located on a low partially cleared hill top approximately 22 meters above the surrounding land, within a 5km radius of the test site we can count over 80 hills of the same height or higher, of course most of the population is located on the lower land making it a very challenging environment for wireless communications.
Although with TVWS a maximum antenna height of 33m (100ft) is allowed we only had a test mast of 14.5 meters (45ft) available for the tests limiting our coverage. Using Radio Mobile software we prepared an expected coverage map of the area viewable in Google Earth, real world results came in close to the expected results which we will be reviewing with an aim of increasing the accuracy in our area.
We were impressed to see the TVWS equipment routinely make a link where the signal path was obstructed by one or more solid obstacles.
Test 19-21 were conducting as a survey for a test network to see the coverage we could get without moving the base station yagi, the client CPE were spread over a 25 degree arc
All test were conducted with the same 8dBi yagi antennas at base and mobile.
Tests marked with an * were conducted twice once before the leafs left the trees and once after the average variation was 5dBm
