Usage analysis of a large public wireless LAN.
Proc. 2005 International Conference on Wireless Networks, Communications and Mobile Computing, Maui, HI, 1:661-667.
This paper presents a quantitative analysis of the usage
of a large public wireless local area network which comprises of
several components providing outdoor coverage in a city center
and indoor coverage at a university campus and at selected
public city premises. Analysis is based on correlating two types of
data, RADIUS authentication data for determining the true usage
of the network, and access point syslog data for localizing the
usage. Analysis reveals interesting differences in the daily and
weekly usage patterns of different user groups. Analysis of user
mobility shows that users are not very mobile, as less than 10% of
the sessions may involve spatial movement of at least 50 meters.
60% of the stations using the network appear to have a “home”
access point, where the user spends about 80% of the time.
