Field Performance Measurements of a Gbps FSO Link at Covilha City, Portugal

Wireless communications have been increasingly important. Besides Wi-Fi, FSO plays a very relevant technological role in this context. Performance is essential, resulting in more reliable and efficient communications. A 1.14 km FSO medium range link has been successfully implemented for high requirement applications at Gbps. An experimental performance evaluation of this link has been carried out at OSI levels 1, 4 and 7, through a specifically planned field test arrangement. Several results, obtained namely from simultaneous measurements of powers received by the laser heads, TCP, UDP and FTP experiments, are presented and discussed.
