2.  Web-based WiFi Laboratory (WeFiLab)
 WeFiLab mainly focuses on providing students hand-on
experience of doing experiments on real devices through
webpage anytime anywhere.
 It uses the structure of two-level operations, which
facilities increasing the scale of wireless devices and
allows WeFiLab to be extended to more complicated
operations.

3.  For science and engineering students, laboratory plays
acrucial role in their undergraduate degree courses
because the laboratory activities provide the hands-on
problem solving skills and necessary experience for
adopting their knowledge in real-life.

4.  Traditional laboratories
 Shortcomings
◦ Qualified staffs
◦ Budget
◦ only accessible during opening hours

5.  Two approaches for online laboratories
◦ Virtual laboratories
◦ Remote laboratories

6.  Virtual laboratories
◦ Virtual laboratories are based on software to simulate
experiments environment.
◦ No real damages.
◦ missing of reality.

7.  Remote laboratories
◦ Remote laboratories experiments are conducted and
controlled remotely through Internet, using real components
or devices
◦ Too complicated for network beginners as students may
need to write programs/scripts to conduct experiments.
◦ Java, Flash, or ActiveX are frequently used tools for User
Interfaces (UIs)

8.  WeFiLab
 Control and manage various wireless devices for conducting
experiments via Internet.
 No need of writing scripts/programs.
 Plug-in free web based GUI framework.

9. Ø Simulation software.
Ø Emualab.

10. Ø Encouraging students to be fully involved into the
experiments on real wireless devices.
ØHides the details of the complex configurations on
wireless devices from users through the two-level
operation structure.
ØAllows the administrator to add new wireless devices
whenever needed to support more students.

14.  It depends on the number of wireless devices and
what kind of experiments students are doing.
 Students’ diversity
 Lock restriction
 Schedule scheme
◦ Reservation scheme (scheduled)
◦ FCFS scheme (nonscheduled)

15.  Basic experiments
 Advanced Experiments

16.  2 or more wireless routers to form the wireless nodes
array.
 Wireless routers are connected to the server through a
switch on Ethernet.
 Ported with a comprehensive OpenWRT embedded
Linux OS.
 Wireless device adopts Broadcom’s BCM5354,
which is a 802.11b/g Router Systemon-Chip, as the
core of the wireless node

18.  WeFiLab was used as a complement of assignments
for two courses in City University of Hong Kong.
 146 undergraduate computer science students are
involved into the experiment about 802.11 Frame.
 OBTL scheme.

19.  Intended learning outcomes (ILO)
 Teaching/learning activities (TLA)
 Assessment tasks (AT)

20.  This experiment mainly focused on the infrastructure
mode of IEEE 802.11 WLAN.
 Overview
 Experiment Details
 Results and Analysis

21.  WeFiLab on Smartphones
 Interference
 Relationships of Roles
 More Technologies
 Education and Research

22.  It aims to provide undergraduate students for hand-on
experience of doing wireless network experiments on
real devices.
 With the web-based GUI, it enables students to do
experiment on webpage via Internet anytime
anywhere.
 Two-level operations to coordinate the
communication between clients and wireless devices.
