Post-pandemic telecommunications

If the Covid-19 pandemic had occurred in 2002 instead of SARS we would have been in much greater trouble. Fewer than 16% of Australian households had broadband in 2002 (today it is up to 91%). Videoconferencing solutions were limited to expensive (and user-unfriendly) corporate systems and were certainly not available to households. IP/Cloud contact centres were available but had virtually no adoption. Streaming video was beyond our wildest dreams.

Fortunately in 2020 these solutions were available and affordable but, until the pandemic, not really exploited by consumers and businesses to any great degree (in the first 8 weeks of the pandemic e-commerce sales – as a percentage of retail sales – increased more than the previous decade).

The pandemic has changed our expectations of telecommunications. It is now an essential part of daily life and businesses cannot operate without it. However, as the recent Hartsuyker Regional Telecommunications Independent Review Committee has found, the availability of telecommunications is not uniformly spread across the country. Some 30% of the population live outside capital cities and often face major challenges with their telecommunication services. In this talk, I shall discuss some of those challenges and also the technology considerations that must go into addressing them. For example, will Low Earth Orbit (LEO) Satellite constellations solve all the major issues and will they make NBN geostationary satellites obsolete?

Another major frustration for users across the country, but particularly in regional areas, is the massive rise of spam and scam calls and texts. Is the ACMA doing enough to combat this? For example, why are carriers not mandated to implement the STIR/SHAKEN protocols? Why are Australian phone numbers so widely available? Again, this will be another point of discussion in my talk.


Hugh S. Bradlow is President of the Australian Academy of Technology and Engineering. He is also Chair of the Board of ASX-listed company Rocketboots and an independent Non-Executive Director of Silicon Quantum Computing Pty Ltd. He also served on the Regional Telecommunications Independent Review Committee for 2021.

He was previously Chief Technology Officer and Head of Innovation at Telstra, responsible for the R&D of new technologies and their introduction into Telstra’s business.

Before joining Telstra in September 1995, Professor Bradlow was Professor of Computer Engineering at the University of Wollongong in Australia and Professor of Electrical Engineering (Digital Systems) at the University of Cape Town.

Professor Bradlow is a graduate in electrical engineering from the University of Cape Town in 1973 and received the D.Phil. degree for research in experimental nuclear physics from the University of Oxford.

He is globally recognised as a thought leader in telecommunications and was elected as the joint 2009 Australian Telecommunications Ambassador of the Year, named by Global Telecom Business as one of the most 100 most influential telecommunications executives in the world and Smart Company designated him as one of the 12 most influential people in Australian ICT.

Scheduling links in mm-wave IAB Networks 

Scheduling in wireless networks is known to be a hard problem. In this talk, we formulate the scheduling problem for IAB networks and present some distributed scheduling algorithms – one based on back-pressure and a more distributed approach that we call local max-weight. In these, we exploit the tree structure to obtain capacity-achieving algorithms where the complexity does not grow exponentially in the size of the network.

When does chip design become the right choice for your IoT device implementation?

About: IoT and wearables have important challenges such as limited or no access to continuous power and size/weight limitation. Edge computing in IoT devices can reduce the amount of data communication. It also offers other benefits such as increased response time​, and reduced number of interfaces with the cloud​. However, it puts more pressure on the IoT devices from power consumption and size/weight perspective which play important roles in designing IoT devices, even though microampere microcontrollers have emerged. One solution is to design customised chips to perform specific tasks at ultra-low power consumption. But chip design is extremely expensive. This talk presents the pros and cons of chip designing for IoT solutions.

Optimizing computer vision

  • Date: Thursday 24th June 2021 
  • Time: 5pm to 6pm
  • Location: Virtual
  • Registration:


A picture may be worth a thousand words, but a single static view is seldom adequate. When faced with a complex visual scene, we employ a range of voluntary and involuntary movements to assess and scan the scene. These include binocular eye movements, such as saccade and vergence, and may also include movements of head and torso to improve the viewing of occluded parts. In effect, we select a set of visual poses to gradually build up our knowledge of the scene.

Similarly in computer vision, acquisition of the most relevant information from a scene is a critical basis for a range of applications, including robotics, surveillance and 3D reconstruction. While there is a wealth of research on algorithms that use the acquired information, little research exists on how to optimize the acquisition phase, that is, how to best arrange the cameras to obtain the most informative viewpoints from the scene.

We have proposed the concept of Correspondence Field (CF), which is a conservative vector field in front of cameras, to quantify the ability of cameras in obtaining information from every point of the scene. In this talk, I will demonstrate the utility of CF in optimizing the position and orientation of cameras to obtain the best viewpoint. As an example, I will focus on improving the estimate of object depth, which is foundational for most computer vision applications. Our experiments show that CF optimization results in significant improvement in accuracy of depth estimation and this enhancement is independent of, and additional to, any algorithmic refinements for correspondence matching.

November 2020


It is well known that coherent light beams have an angular momentum associated with them. This is the well-known phenomenon of polarization and  is the direction of oscillation of the electric field of the electromagnetic wave.  In the quantum mechanical view of light, it  is associated with the intrinsic spin of the photons. From a communications engineering viewpoint, this enables two orthogonal channels in, for instance satellite television, thus doubling the channel capacity of a given frequency.

In recent years it has been recognized that there is another angular momentum associated with a coherent light beam. This is called orbital angular momentum (OAM) and is also associated with a quantum mechanical parameter. It corresponds to solutions to Maxwell’s equations with helical wavefronts and, unlike polarization, can, in principle, take infinitely many orthogonal states. The OAM of a coherent beam can be any integer. Creation of low integer OAM states is not very difficult with both metamaterials and computer generated holograms being used. Similar devices can be used to filter light beams to detect such states.

 The ability to reliably create and detect such states holds great potential for communications using electromagnetic waves, both in free space and in optic fibres. Effectively, it is possible to create a number of orthogonal communication channels at a given frequency in an optical fibre.

Our speaker will talk about the theoretical ideas behind this new technology, as well as a few practical aspects and uses in communications.

Recently, there have been several important regulatory actions in the United States in response to industry developments of the next generation of mobile technologies. Following the release of several GHz of spectrum in the mmwave and sub-mmwave ranges a few years ago, the US FCC embarked upon releasing additional spectrum in the mid-ranges to accelerate the expansion of 5G. These efforts, aside from being exceptionally expeditious, have used novel approaches to arrive at suitable regulatory solutions. From financial incentives to FSS operators in C-band to devising an Automated Frequency Coordination (AFC) vehicle in 6 GHz, these bold solutions are leading to several “first of its kind” solutions, paving the way towards taking full advantage of recent technological developments such as 5G and Wi-Fi 6E.

In this presentation, we look at background and outcome of the FCC’s proceedings related to these bands.

With video traffic accounting for more than 60% of the global downstream Internet traffic in 2019, video streaming represents a significant portion of inbound traffic to the home environment. Recently, the Internet Engineering Task Force (IETF) has standardised three Active Queue Management (AQM) schemes – PIE (RFC8033), CoDel (RFC8289) and FQ-CoDel (RFC8290). These schemes are being progressively deployed at the last-mile Internet Service Providers’ (ISP) end-points and home gateways to counteract bufferbloat and will likely impact consumer video streams. This talk presents the benefits of the emerging AQM schemes in broadband networks and their impact on video streaming traffic and an experimentally validated technique that has been proposed for improving streaming performance in typical consumer home broadband environments.

The world and broadband now evolve to a new normal.  A centennial pandemic suddenly intensifies our broadband dependency and mandates more ubiquitous and reliable communication everywhere, including Australia’s NBN.   What does this mean for broadband evolution plans?  What must change?  What can change? Fiber to everyone’s wristwatch was never an economically viable solution, but there are paths that address need and viably advance into the new altered future.  Existing facilities’ combined intelligent leverage, and best use of advanced, powerful, and distributing computing can indeed provide viable solutions.  This talk investigates such paths, how to measure their advance, and suggests paths that transcend well into tomorrow’s New Broadband Normal.

In 5G networks, mobile service providers will support vertical slices of mobile applications to meet diverse service quality requirements, such as ultra-low latency, densely distributed users and high reliability. Meanwhile, wireless traffic is explosively growing, driven by widespread mobile communication devices and increasing popularity of mobile applications. The wireless network slicing technique, which is built on network function virtualization and software defined network schemes, will support wireless applications on substrate physical facilities with higher flexibility and lower cost.

A scheduling policy for wireless network slicing should maximize the energy efficiency of the network. (Here, we define energy efficiency as the ratio of long-run average throughput of user requests to the long-run average power consumption.) This is a problem of extremely high computational complexity, which prevents direct application of conventional optimization techniques. We have developed a policy called Most Energy-Efficient Resource First (MEERF), which is scalable and priority-based. MEERF is asymptotically optimal in a local wireless environment with highly dense user population and exponentially distributed service times. Our extensive simulations show the robustness of MEERF to different service time distributions. We also show the effectiveness of MEERF compared to benchmark policies in a more general network with potentially geographically distributed users and infrastructures.

The presentation will provide a brief introduction to 5G and what it means for electromagnetic (EMF) exposure based on the results of assessments of 5G networks (commercial and pilot) conducted in Australia and overseas.  The international EMF exposure guidelines were updated in March 2020 and one of the major changes was to provide more detailed guidance for frequencies above 6 GHz. Independent public health agencies say that no health risks are expected for 5G but myths and misinformation continue to be spread on social media, including suggestions of a link between wireless technologies and COVID-19. Pointers will be provided to reliable sources of information.
