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 FSO medium range link has been successfully implemented for high requirement applications at Gbps. An experimental performance evaluation(More)
A very high speed FSO (free space optics) link has been successfully implemented for purposes of high requirement applications, at the University Campus. An experimental performance evaluation of this link has been carried out at various OSI levels (1, 4, and 7). Several results are presented and discussed.
The importance of wireless communications has been growing. Performance is a most relevant issue, resulting in more reliable and efficient communications. Security is crucially important. Laboratory measurements are made about several performance aspects of Wi-Fi (IEEE 802.11 b, g) WEP point-to-point links. A contribution is given to performance evaluation(More)
Wireless communications using microwaves are increasingly important, e.g. Wi-Fi. Performance is a very important issue, resulting in more reliable and efficient communications. Security is equally very important. Laboratory measurements are made about several performance aspects of Wi-Fi IEEE 802.11g WPA point-to-point links. A contribution is given to(More)

1 —Wireless communications are increasingly important. Performance is a very relevant issue. Laboratory measurements are made about several performance aspects of Wi-Fi IEEE 802.11a, b, g point-to-point links, using two types of access points from Enterasys Networks. Detailed results are presented and discussed, namely at OSI levels 4 and 7: TCP throughput,(More)
