摘要：
Wireless communications using microwaves are increasingly important. Performance is a very relevant issue, resulting in more reliable and efficient communications. Laboratory measurements are made about several performance aspects of WiMAX (IEEE 802.16d) and Wi-Fi (IEEE 802.11a, b, g) point-to-point links. An initial evaluation and comparison of these technologies is made, using Alvarion equipments and access points from Enterasys Networks. Through OSI levels 1, 3 and 4, detailed results are presented and discussed, namely: SNR, latency and ICMP packet loss. It is concluded that WiMAX, which is an important emerging and rapidly expanding wireless wide band technology, shows the best performance.
