Abstract 

High-speed metro and access networks are indispensable to provide broadband services, especially bandwidth-hungry services and future 5G mobile networks to end users. Such networks should not serve only low-mobility users, but also those on fast-moving objects such as high-speed trains. Advanced wireline and wireless network solutions with ultra-high capacity, low transmission delay, high energy efficiency, and low cost need to be developed to support a wide range of applications and requirements in future networks. The convergence of wireline and wireless networks should also be considered to simplify the network configuration, management, and to realize new features and functions. Advanced photonic-based transmission systems are thus of critical importance to facilitate future mobile and wireless communications. In addition, high-performance imaging would play an important role to enhance safety and security of public infrastructure including airports, railways, etc. High-resolution radars can be constructed by the use of millimeter-wave and terahertz-wave where wide radio frequency resource is available. To cover wide ranges, a combination of radio and optical technologies via radio-over-fiber technology would be very useful to distribute and collect radio-wave information. This tutorial will present technical challenges, possible paths, and enabling system/device technologies for future mobile transport networks, including mobile backhaul and fronthaul. It will also discuss photonic-based millimeter-wave and terahertz-wave radar systems and related technologies for applications to public services, disaster recovery, etc.

Applications of Mobile Robots and Drones in Future Wireless Communication Systems

Des McLernon

School of Electronic & Electrical Engineering, University of Leeds, Leeds, UK

Email: D.C.McLernon@leeds.ac.uk

Abstract 

In parallel with the well documented comms revolution (e.g., internet, cellular phones, social media, etc.), another technological revolution is taking place with robotics. Robots (fixed, mobile, UAVs/drones) have recently been named as one of the world’s ‘eight great technologies’. In particular, by virtue of their mobility they can be used to assist in meeting the huge wireless communications demands outlined above. In this tutorial level talk I will show how signal processing allows mobile robots (either individually, as relays or as swarms) to enhance communications links and meet the aforementioned and other challenges. Specifically I will introduce:

  1. how the new concept of intelligent trajectory planners allow mobile robots to find (in an energy efficient manner) the optimum position from which to wirelessly upload data;
  2. how we can use efficient energy harvesting to assist robotic communications;
  3. how robotic arrays can use communications and signal processing in ‘search and rescue’ scenarios;
  4. how to optimise the communications performance of drone-based small cells (e.g., emergency response for resilience in future cities through to temporary cellular services for major events).

In-band Full-duplex Radios: Networking and Security Issues

Diep N. Nguyen

University of Technology Sydney, Australia

Email: Diep.Nguyen@uts.edu.au

Abstract 

The self interference suppression (SIS) capability allows a transmitting device to suppress its self-interference up to the noise floor, enabling two wireless radios to simultaneously transmit and receive on the same channel and even using the same antenna array. Radios with this in-band full-duplex (IBFD) capability have the potential to not only double the network throughput but also help solve various issues (e.g., Tx deafness, hidden/exposed nodes) at the MAC and network layers. Additionally, one can exploit the SIS capability in various applications like indoor localization, securing wireless transmissions. This talk gives an overview on recent developments of SIS and its implications on wireless networking and securities. Our latest findings on the network capacity, anti-jamming solutions, eavesdropper countermeasures for IBFD radios and their experimental prototypes are also discussed.
