The Mobile Communications and Networking research department has two focus areas: 1) Technologies for improving the capacity, coverage and scalability of next generation 5G cellular networks, and 2) End-to-end solution creation leveraging various forms of wireless sensing and communication technologies such as RFID, Bluetooth, WLAN and cellular in multiple vertical industry domains.

In the 5G cellular network domain, the department's research encompasses development of technologies both on the RAN (Radio-Access Network) as well as the Mobile Packet Core (EPC). Within the RAN, technologies such as massive MIMO/MU-MIMO, millimeter-wave access (e.g., transmission at 28 GHz to nomadic/mobile users), dual-connectivity LTE-A solutions and LTE transmission in the unlicensed band are being developed. At the mobile core, the focus is on virtualization, scalability and cloud deployment of EPC network elements as well as provision of appropriate services at the mobile-edge (MEC) and the cloud using service chaining.

Research on end-to-end solution creation using multi-modal sensing technologies (with wireless being the main mode of sensing/communication) is a major new thrust for the department. The iniial vertical industry domains currently under consideration are retail, public safety and transportation. In the area of retail solutions, the focus so far has been on development of technologies to be deployed in the store-front to enable better shopping experience for the user and at the same time collect data to be mined by the retailer for more efficient store operation. In the domain of public safety, the focus has been on leveraging autonomous aerial vehicles to deploy on-demand communication and tracking solutions for aiding in first responder missions. In the area of transportation, the focus has been on smart-parking and other traffic optimization technologies for urban transportation. The focus within our department on end-to-end solution development is expected to undergo substantial growth in the near future.
