This course covers today's state-of-the-art
wireless technology 5G New Radio, 4G LTE, the next-generation wireless
technology vision for 6G, and fundamental Wi-Fi technologies. Internet of
Things (IoT) and the network slicing technologies in the 4G and 5G mobile
networks, which are the parts of the main drivers for 5G, and the Docker container
and Kubernetes will be also covered. Students will use an end-to-end 4G LTE and
Wi-Fi application performance simulation platform to analyze network protocols
and analyze the impact on end-to-end application performance over the wireless
network. Students will also build a simple IoT service with a real IoT client
device and IoT server platform on the Internet. The course starts with the
fundamental wireless technology background and networking topics with hands-on
projects to help students building a foundation for the course, and the course
includes contemporary research paper readings, assignments to utilize the
simulation platform and implementation projects. The simulation platform
provides network protocol stacks and base source code.
● Understand the technology evolution path of, and
the demands driving, wireless technology and mobile networks, the global
technology standardization process, some of the major mobile network
technologies and IoT technologies.
● Confidently discuss key wireless mobile terms
and technologies with wireless mobile network domain experts as one of their
own.
● Use new technology design principles, and the
key factors that can improve the wireless network performance to build a proof of concept network system.
● Read and analyze technical papers from the
wireless communications domain, extract and evaluate their key messages, and
write comparisons between them.
● Set up a variety of real-time traffic monitoring
systems and use them to analyze network traffic
● Design a traffic split and aggregation algorithm
that utilizes both LTE and Wi-Fi networks to increase the network throughput
under various network conditions.
● Build your own IoT device emulator and setup an
end-to-end IoT service through a real public IoT server.
The course projects require knowledge of C/C++.
Any undergraduate networking courses are suggested but not required as this
course covers necessary networking topics.
● Lecture note will be available, and additional reading
material will be drawn from selected research publications and standard
specifications
● Textbook Recommended

You must attempt all graded assignments to pass
the course. If you have any questions or concerns about grading or progress in
the course, please reach out to the instructor.
This course will use a variety of assessments to
determine whether learners understand and can apply the key concepts and skills
that the course teaches. This includes:
|
Type |
% |
Description |
|
Quizzes (Take
home) |
14% |
There
are seven on-line short quizzes, providing an opportunity to review the
lectures. You will complete the quizzes at home by the due date and you can
try two attempts for each quiz. |
|
Projects |
43% |
There
are 5 projects, providing an opportunity to apply lectures to real-life
wireless communications applications and programming. Project 1, 2, 3, and 4
will be done in a team, and the project 5 will be done individually. Team projects: Project 1(8%): Network Packet
manipulation and TCP packet trace analysis Project 2(8%): Build Wi-Fi
simulation in NS3 and TCP performance analysis over Wi-Fi Project 3(7%): Build LTE
simulation in NS3 and TCP performance analysis over LTE Project 4(15%): Traffic split and
aggregation over Multi-Radio Access Technology (LTE and Wi-Fi) simulation Individual
project: Project 5 (5%): Build a simple
IoT service using LoRaWAN devices (hardware or
emulator) and an IoT server platform on the Internet |
|
Midterm
Paper |
18% |
(15%) There
is one midterm paper, which will be a comparison paper (using three reference
papers) on existing research. This
paper includes a peer review component. (3%)
Peer paper review |
|
Final
Exam |
25% |
There is
one final exam. The final exam will cover from the LTE lecture to the last
lecture. A final exam preparation slide deck (about 55 pages) will be
provided, and you are allowed to bring one page hand written summary paper (letter
size) prepared by you. |
Please read
the instructions for each assignment very carefully to make sure you know what
to submit to receive credit!
Late
Policy/Extensions
An assignment that is turned in late will receive a 10% grade reduction
per day up to 2 days. No other extensions unless there is an acceptable reason
with prior notification.
Regrade Requests
Regrade requests are handled on a case-by-case basis and are allowed up
to 1 week after the grades are released. Regrade requests may take up to a week
to process. When submitting a regrade request, please explain (in detail) why
you feel the grading is incorrect.
Extra Credit
Students may earn extra credit at the discretion of the faculty if a
student goes above and beyond during assignments.
The following activities are
not mandatory, but will greatly support your success on the graded assignments.
Discussion forums (Ed
Discussion) are designed to give you optional extra practice with the material
and to see examples of how your classmates are thinking and working.
The instructor will provide one-on-one session
to the student who needs more focused support. If a student sent an email for support,
then the instructor will arrange a time slot with the student and prepare a
one-on-one zoom session.
The instructor encourages students to use this
opportunity to gain knowledge as much as possible from this course.
The professor may add
additional optional segments to support the class as needed.
Discussion forums and recitations are collaborative—please take advantage
of those times to work with your colleagues. For general communication with
your colleagues, use the Piazza messages.
Forming study groups to understand the material
is also a good idea, as long as you stay on the conceptual level and are not collaborating on the graded
assignments directly.
Note: When in doubt always ask the instructor or
TA first, to avoid any potential collaboration that can lead to academic
dishonesty.
Do not cheat. Please note that searching for previous solutions online is the same as
cheating.
You can further read Penn's Code of Academic Integrity page on this subject matter, as well as the
SEAS Graduate Student guidelines on the code of ethics.
Dates are subject to change. Please check Piazza
for announcements regarding schedule changes.
