Outdoor WLAN communication is envisioning an increasing interest, due to the massive emergence and deployment of outdoor wireless Mesh Networks. This paper provides a report on an extensive measurement campaign carried out in an outdoor Wireless LAN Campus scenario. A public domain driver, namely MADWiFi, has been modified in order to achieve a high (per-node and per-frame) measurement granularity, and in order to distinguish the different causes that contribute to link-layer errors. The main result of our experimental investigation is that, unlike 802.11b, which appears a robust technology in most of the operational conditions, 802.11g may lead to severe inefficiencies when employed in an outdoor scenario.
