Laboratory and outdoor availability and spatial coherence tests of wireless optical links

Abstract

Wireless optical links can bring new added technologic approach atop of today's wireless networks forming their backbones and subparts. However several measurements have to be performed in order to get close insight on their availability within infrastructures. The paper reports recent tests at the Czech Technical University in Prague in cooperation with Northumbria University. New testbeds have been developed for outdoor and indoor measurements. Together with reports from packet and BER measurements, paper introduces complementary results on spatial coherence measurements for single link influenced by turbulence.
