Department Description

Our 5G cellular network research encompasses development of technologies both on the radio access network (RAN) 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, our 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.

Our department is also conducting extensive research on creating end-to-end solutions using multimodal sensing technologies in the retail, public safety and transportation domains.

End-to-End Solutions Using Wireless Sensing & Communications

In this area of research, we focus on developing solutions for different industry domains based on multimodal sensing and communication technologies, with wireless playing the major role. In the retail world, we have been developing a suite of technologies to be deployed in the storefront to both enable a better customer shopping experience and provide valuable data to the retailer. Our Virtual Shielding technology provides a seamless checkout solution using RFID, which is more cost effective f…

5G Cellular Networks

Our current research considers a range of topics in the domain of 5G Cellular Networks within the RAN and the EPC.In developing technologies for deploying massive MIMO systems, we are exploiting the systems' decorrelation property to avoid unnecessary pre-coder computations, thereby reducing scheduler overhead.In our work with millimeter wave technologies, we are developing solutions using beam tracking technology that do not require explicit channel measurement. We are also creating a nov…

NavigateIO

First responders, a critical lifeline of any society, often find themselves in precarious situations. The ability to track them real-time in unknown indoor environments, significantly contributes to the success of their mission as well as their safety. In this work, we present the design, implementation and evaluation of TrackIO – a novel system that is capable of accurately localizing and tracking mobile responders real-time in large indoor environments. NavigateIO leverages the ultra wide-ban…
