DragonWave says that it has completed a series of outdoor small cell backhaul propagation tests that have been conducted with an unnamed 3rd party for street level characterization.

This testing has validated and characterized non-line-of-sight (NLoS) paths at street level utilizing 60 GHz small cell backhaul deployment technologies. The exercise also validated and characterized the accuracy of NLOS path predictions in order to improve deployment and network planning.

As a result, the testing characterized distance limitations that are experienced by street level line-of-sight (LOS) paths due to flat fading. Flat fading had been found to limit urban paths with no incline to less than 400 meters, even with sufficient planned path fade margins. This testing focused upon how flat fading can be improved with various angles of incline.

Tests were made with and without vehicular traffic, characterizing RF channel behavior in LoS and NLoS conditions to verify product performance and determine best deployment practices.

"Conducting street level, outdoor small cell backhaul testing has enabled us to successfully characterize NLOS operation in the 60GHz band, through the first reported characterization of V-Band performance on Urban NLOS paths," said Erik Boch, DragonWave CTO and VP of Engineering. "We have gained actionable knowledge about how to combat path limitations that are present in urban deployments, and our network planning service will support both improved small cell performance and deployment capabilities"
