Abstract
Interests in location-aware systems and services have been growing with the proliferation of
mobile computing devices and wireless networks. In indoor environments, location estima-
tion systems that utilize the underlying 802.11 WLAN infrastructure have gained more and
more attention because no extra hardware is required for these systems. Most previous pub-
lished works for 802.11 WLAN location estimation systems have focused on improvements
in location estimation accuracy, reduction in system setup e®orts and designs of analytical
models. However, the AP deployment issues have not been much discussed in literature.
We've developed an AP deployment algorithm, which can determine the total number and
the deployed locations of APs based on a certain accuracy level for a given indoor environ-
ment. We'll show our algorithm can produce AP deployments which help yield near optimal
accuracy in WLAN location estimation systems.
