FET’11 Deployment: In the second set (conference) of
experiments, a number of weeks after our initial deployment,
we tested our system in a less controlled environment. The
performance fine-tuning after the first set of experiments
allowed us to scale the system even further. As this was a
larger scale deployment and was done in harsher conditions,
we used a larger team of people to setup and operate the
infrastructure (5). The setup was completed within 4 hours
on the day before the opening of the conference (FET’11)
to the public. In contrast with the CTI deployment, the
networking isolation offered by walls and doors was not
available, making it more difficult to determine the location
of participants. As seen on Fig. 3, the infrastructure was
installed behind booth stands, while visitors registered upon
their entrance to the venue, and then installed the application
for their smartphone (Fig. 1).
