Next Generation Wireless Systems Lab

Welcome to Next Generation Wireless Lab

These are exciting times in the field of wireless research. Wireless communications now affects all our lives in multiple ways, the common examples being cellular phones, wireless local area networks, back haul microwave links, etc. Wireless technology is expanding at a rapid pace, and is now finding several more applications such as in wireless sensor networks, factory automation, vehicular communication, personal area networks, body area networks, etc.

The current research work in the lab focuses on performance analysis and design of next generation cellular mobile radio systems such as HSPA, LTE, and WiMAX, wireless system and protocol design for energy harvesting wireless sensor networks, cognitive radio, cooperative communications, multiple antenna systems, and interference modeling.
