 The fully networked human? − Innovations for future networks and services
  ITU Kaleidoscope event, 12 − 14 December 2011, Cape Town, South Africa
Welcome Host: Francis William Petersen (Dean, Faculty of Engineering & Built Environment, University of Cape Town, South Africa)

The fourth in the Kaleidoscope Conference Series will be held for the first time on African soil, and the University of Cape Town is proud to host the Conference in collaboration with the South African Department of Communications.

When focusing on the theme of the Conference, the value that the multi-disciplinary aspects of information and communication technologies (ICTs) could add to human centred systems is immense. The connection between humans and machines will need focused innovation, and the progressive developments in broadband networks can facilitate the better understanding of such interface. It is indeed in Africa where the challenge for a multi-disciplinary approach is critical.

It is not only about access to ICTs which have high-speed characteristics, but it is also about accountability and security to applications and end users.

In the context of Africa, ICTs need to be reliable and affordable, and I will explain how to address these challenges appropriately.
Keynote speech: 2020: The Ubiquitous Heterogeneous Network - Beyond 4G. Rufus Andrew (Managing Director, Nokia Siemens Networks, South Africa)

The demand in mobile broadband communication continues to increase exponentially, fuelled largely by the proliferation of smarter and smarter devices. Smartphones, superphones, and tablets with powerful multimedia capabilities and applications are becoming increasingly popular and are creating new demands on mobile broadband.

This trend is expected to increase in momentum over the next decade and will be further fuelled by the arrival of billions of billions of machine devices and related machine-to-machine (M2M) applications and human to machine communications. As the interfaces and capabilities of mobile devices start accommodating broader radio-frequency (RF) capabilities and technologies such as RFID (radio-frequency identification), mobile networks will play an increasing role in the backhauling and fronthauling of signals that will be connected to the ’Internet of Things’

These factors are adding up to create an exponential increase in traffic volumes, number of transactions, and complexity of processing. Extrapolations of current growth trends predict that networks need to be prepared to support up to a thousand fold increase in total mobile broadband traffic by 2020. This figure assumes a ten-fold increase in broadband mobile subscriptions and up to 100 times higher traffic per user

To meet such demand, the industry needs to look ahead of today’s technology horizon to create ‘Beyond 4G’ Networks. In order to successfully achieve this, industry collaboration is needed to deliver on the following requirements.

1. Ten times more spectrum will need to become available for mobile broadband
2. Networks will need to use spectrum ten times more efficiently than existing mobile broadband technologies
3. Networks will require ten times more base stations

This presentation looks in detail at these requirements with possible solutions for the ‘Beyond 4G’ Network.

Finally we look at the impact of the ‘Beyond 4G’ Technologies bridging or further entrenching the Digital Divide.
Keynote speech: Recovery from the Communication Disturbance by the Tohoku Earthquake and Actions toward the Future.
Hirofumi Horikoshi (Technology Planning Department, NTT Corporation, Japan)

The Tohoku Earthquake and the successive tsunami on 11 March 2011 crashed down the significant areas of NTT’s communication services. 385 central offices, 4,900 base stations of our cellular network service and 150 million telephone circuits became out of order. This talk shows: (1) how NTT made efforts for the recovery of its network, (2) how to keep communication services in the disaster regions, (3) how to provide livelihood support to the sufferers, and (4) the possible future action plans.

Despite many aftershocks, where some of them were over a magnitude of seven, as shown in Fig. 1, the communication system was recovered by the end of April, except 18 base stations. Even in the areas surrounding the nuclear power plants, people could communicate with each other. The major means for recovery were (i)new constructions or replaces of power supplies as well as communication facilities in central offices, (ii)reinstallations of transmission paths, (iii)repairing entrance circuits for base stations, (iv)expanding cellular zones, etc.

3,600 public telephone booths with portable satellite links, 31 automobiles equipped with base station, 900 satellite cell-phones, 2,100 mobile phones and 410 battery charge booths were provided free of charge. 336 free internet corners, free WiFi services as well as 670 free tablet terminals were also provided for the internet connectivity. The Web page was launched to show the map of recovered regions. Labor-intensive operations were also made. For the people in evacuation centers, we sent messengers to receive messages about the well-being of those people and to transfer them to the relatives, the mass media, and the Web page.

Now several actions are planned toward fault-resilient network infrastructure. The first one is to make the power supply of base station uninterruptible. For this aim, 1,900 base stations will have long life batteries such as 24 hours, which cover 65% of the population. The second is to construct 100 large zone base stations in the densely-populated areas, which cover 35% of the population of Japan. The third is to increase the number of physical routes for each trunk circuit, to introduce the distribution of network functions, to improve waterproof central offices, etc.

From the lessons learned at this disaster, we will introduce a new voice message service as shown in Fig.2, which sends a voice to the destination as a recorded file to avoid the congestion of telephone service. It is very useful to send a message as “I’m alive!” to our relatives at a disaster, and will be one of the most important life saving tools.

Keynote Speech: The fully networked human-ity? - Innovations for the un-networked human
Alfredo Terzoli (Rhodes University, South Africa)

There is a growing perception that the many divides that fracture the humankind are problematic. Divides do generate instability (to the point of revolutions or wars) and have obvious inefficiencies, deriving from the fact that, as humans our (collective or social) strength is in the group, not in the individual.

One such divide is between those that are connected to the global information cloud, the Internet or those that are not. On this divide, often referred to as ‘digital divide’, millions of words have been spent, but without any major concrete change: the problem is still with us, no matter how clichéd it sounds by now.

Interestingly enough, this divide runs along others, such as the one between the rich and the poor, and the educated and the uneducated. Maybe bridging one divide can help bridging the others? What type of innovations do we need to start bridging the digital divide for real - and so potentially other divides? What systems should be in place, what standards, what practices? This talk will try to answer these questions focusing on an ongoing experiment in Dwesa (Wild Coast, South Africa), the Siyakhula Living Lab, at the centre of a rich innovation ecosystem.
The disappearance of Telecommunications and the fading of boundaries among atoms and bits
Roberto Saracco (Telecom Italia, Italy)

Forecasting 50 years in areas where technology evolution dominates is impossible. However, some trends that have been manifested in the last fifty years can tell us something. It would be a mistake to look at these trends and simple prolong them into the future because we are reaching some singularity points where what used to be true may no longer apply.

The goal of the talk is to reflect on some of these singularity point and provide some guess of what may lie beyond their horizons.

What means to have unlimited pervasive bandwidth? What means when there is no separation between an object and its representation, when it becomes irrelevant to distinguish between atoms and bits? How will our physical limits, as human beings, constrain the exploitation of what is beyond our limits?
Atlas of Technology Advance
Rias J van Wyk (Technoscan Centre, USA)

Taking a “Jules Verne View” of the management of technology (MOT), we expect three developments in the coming decades: (i) A uniform technological language to rationalize the various technological dialects that are in use at present. (ii) An atlas of technology based on the uniform technological language (iii) The emergence of a “science of technology” as a coherent discipline.

The atlas of technology will be used in three applications. To track technological evolution, to structure technology foresight, and to construct an Omega map of achievable technological performance. An example of each application will be covered in the presentation.
