CIS 549/001

Wireless Mobile Communications

Fall 2017


Instructor: Bongho Kim

Email: kimbong@seas.upenn.edu

Class Schedule: Wednesday, 6:00-9:00pm, Towne 311 

Office hours: TBA


Course Description:

This course covers generations of wireless mobile network standards and systems, basic differences and their evolution, charting the development of mobile telecommunications systems from 3G UMTS, to today's state-of-the-art wireless technology 4G LTE, and includes a previous technology, WiMAX, and the next generation wireless technology, 5G. It covers the architectures and their network elements, protocols, functional entities, the connection setup procedures, and the call flow of the mobile networks. Students will use an end-to-end LTE application performance simulation platform for quantitative performance analysis and design of LTE services networks. Student will be introduced to a discrete event simulation platform to analyze network protocols and analyze the impact on end-to-end application performance over wireless network. The course includes fundamental networking topics (i.e. TCP/IP, Routing) with hands-on projects, contemporary research paper readings, book chapters, presentations, assignments to utilize the simulation platform and implementation team projects. The simulation platform provides the network protocol stacks and base source code.

Prerequisites:  

Any undergraduate networking or distributed systems courses (e.g. ESE 404, ESE 407, CIS 505, CIS 551, or CIS 553) are suggested but not required as this course covers necessary networking topics. Course projects require knowledge of C/C++.

Course materials:

         Lecture note will be available

         Additional material will be drawn from selected research publications
