Anteumbler: Non-Invasive Antenna Orientation Error Measurement for WiFi APs

Autor: Yan, Dawei, Yang, Panlong, Shang, Fei, Freris, Nikolaos M., Yan, Yubo

The performance of WiFi-based localization systems is affected by the spatial accuracy of WiFi AP. Compared with the imprecision of AP location and antenna separation, the imprecision of AP's or antenna's orientation is more important in real scenari

Publikováno v: Annals of Geophysics, Vol 56, Iss 5 (2014)

According to the well-performed ionospheric heating experiments at Arecibo in the low latitudes as well as at Tromsø in the high latitudes, the large-scale modification effects are simulated under an assumption of equivalent conditions, i.e., with t
