Santosh Ganji

Researcher (Texas A&M University)

Santosh Ganji received master's degree from Indian Institute of Technology, Hyderabad, India.
He is currently pursuing doctoral degree at Texas A&M University, advised by Dr. P. R. Kumar.
He has good experience in building wireless modems using software-defined radios. He understands cellular standards,
builds early prototypes, and evaluates the performance in the wild. His main interests are mm-Wave Networks and
Cellular Networks. He contributed to Cellular Internet of Things standards and
demonstrated his work at SIGCOMM’20,’21,’22. In his free time, he takes pictures of high-speed subjects: Fighter Jets and Hummingbirds

Management of narrow directional beams is critical for mm-wave communication systems. Translational or rotational motion of the user can cause misalignment of transmit and receive beams with the base station losing track of the mobile. Reacquiring the user can take about one second in 5G New Radio systems and significantly impair performance of applications, besides being energy intensive. It is therefore important to manage beams to continually maintain high received signal strength and prevent outages. It is also important to be able to recover from sudden but transient blockage caused by a hand or face interposed in the Line-of-Sight (LoS) path. This webinar presents beam management protocols that is targeted to the use case of users walking indoors near a base station and identify research directions for Tera Hertz and 6G
