WiMAX ytelsesmålinger i skogsterreng

The need for information flow within and between different units and platforms in the Norwegian Defence is expected to increase substantially over the next few years. To meet this demand, new wireless communication systems with higher data transmission capacities will be required, not least in tactical units. A number of civilian standard based mobile broadband technologies have emerged over the last few years that may, at least partially, help solve this challenge. This report investigates the usability for mobile broadband systems in the Norwegian Defence with a particular focus on the IEEE standards 802.16-2004 and 802.16e-2005, fixed WiMAX and mobile WiMAX, respectively. The report presents results from WiMAX field trials conducted in Hedmark, Norway during the autumn of 2007. Measurements were performed on a 2.3 GHz WiMAX setup acquired by the Norwegian Army. The results from the measurements show that a throughput of several Megabits per second can be achieved even at distances of several kilometers. Results also indicate a strong dependency between terrain, vegetation and network performance.
