Course DescriptionThe millimeter-wave (mmWave) technology, especially in the unlicensed frequency band around 60 GHz, is considered as one of the primary enabling technologies in the upcoming 5G mobile network architecture, offering an attractive alternative to today's over-crowded WiFi and cellular bands. The very small wavelength at 60 GHz allows for tiny antenna arrays that can form highly directional beams, enabling multi-Gbps data rates. The caveat is the high attenuation of mmWave links due to the small wavelength. For example, a human in the line-of-sight between the transmitter and the receiver can attenuate the signal by 20-30 dB, resulting in total link outage. Additionally, directional transmissions pose a great challenge to mobility as mobile clients and APs may have to continuously rearrange their beams. On the other hand, the short wavelength and high directionality translates in high sensitivity, enabling a number of wireless sensing applications, e.g., mobile radar imaging, motion tracking, and vital sign monitoring.
The seminar will cover the state-of-the-art in mmWave networking and sensing. Example topics include: 60 GHz performance in indoor/outdoor environments, 60 GHz power consumption, MAC protocol design and implementation (e.g., for beam/rate adaptation), mmWave WLANs, picocells, WPANs, and mesh networks, 60 GHz data centers, mmWave mobile radar imaging, high-precision motion tracking, and vital sign monitoring.
The main goal of the seminar is to help students understand the basic principles as well as the state of the art in a variety of topics in mmWave networks. As a secondary goal, students will learn how to how to read and review research papers and how to communicate technical material effectively.
The seminar is suitable for students who have strong interest in (wireless) networking and intent to pursue a career in the area, e.g., PhD students already working in wireless networking or MS students interested in doing research in the field (in the form of independent studies and/or MS Thesis). One of the goals of this seminar is to identify, by the end of the semester, a set of open research problems on which students can work during the summer or the next semester, e.g., in the form of independent studies.
Pre-requisitesCSE 4/589 and/or CSE 630. Students are expected to have solid background in computer/wireless networking. If you haven't take any of the pre-requisites, and you want to take this seminar, arrange for a meeting with the instructor. Send me an email including a brief description of your relevant background and why you are interested in this seminar.
Required TextbookThe course is based on material from recent conference proceedings and journals. The instructor will provide pointers to the papers in the reading list. The instructor will also provide his own lecture notes when necessary. There is no required textbook for the course.
Course StructureEach week we will discuss one topic. A list of papers from top networking and systems conferences (MobiCom, SIGCOMM, MobiSys, NSDI, CoNEXT, INFOCOM) will be provided for each topic. One of the papers for each topic will be listed as mandatory paper and the remaining ones as related papers. All students are required to read the mandatory papers, submit reviews for a subset of them, and participate in discussions in class.
Each lecture will consist of two parts. In the first part (1.5 hours), we will be discussing the mandatory paper (one student will be presenting). In the remaining time, another student will be summarizing the related papers and lead the discussion on the topic of the week.
In detail, the course includes the following assignments:
