  In highly-dense IEEE 802.11 deployments, areas covered by multiple Wireless
Local Area Networks (WLANs) will be common. This opens the door for stations
equipped with multiple IEEE 802.11 interfaces to use several WLANs
simultaneously, which not only may improve user experience, achieving a better
connection with higher throughput and resilience; but it may also improve the
network utilization. In this paper we investigate such a scenario. First, using
a test-bed, consisting of a single station equipped with two interfaces and two
access points, we observe that the file transfer time between the station and a
destination server can be significantly reduced, studying with special
attention the case in which both links do not have the same available
bandwidth. Then, using a Markovian model that captures the scenario's dynamics
in presence of multiple stations, we observe that in addition to improve
individual station's performance, we can also improve the utilization of a
multi-Access Points network despite increasing the contention level.
