Brough’s keynote address at the October 2010 4G Wireless Evolution Conference.
In it, he argues:
1. All key 4G technologies are pioneered by Wi-Fi (3-5 year lead!).
2. Wi-Fi will be the dominant solution for mobile data offload.
3. 4G technologies represent a wireless tipping point with the result they will revolutionize backhaul and eventually the first mile (via wireless ISPs).
He closes with two slides on his new wireless ISP, netBlazr.

Wireless Network Analysis 101 VoFi (Voice over Wi-Fi)Savvius, Inc
The proliferation of wireless handheld devices, especially tablets and smart phones, puts increased strain on today's wireless networks. As the technology continues to evolve rapidly, network engineers are in a race to keep up—both with system interoperability concerns, and throughput, reliability, and security issues. Now more than ever, you need a solid understanding of requirements and the solutions available for wireless network monitoring and analysis. Special attention is required when managing networks with voice and video over Wi-Fi. This webinar will not only address the tools needed for securing your network and optimizing performance, but will discuss how you can identify and monitor the maximum threshold for voice and video over Wi-Fi capacity.
Li-Fi is the term some have used to label the fast and cheap wireless-communication system, which is the optical version of Wi-Fi. The term was first used in this context by Harald Haas in his TED Global talk on Visible Light Communication(VLC). The technology was demonstrated at the 2012 Consumer Electronics Show in Las Vegas using a pair of Casio smartphones to exchange data using light of varying intensity given off from their screens, detectable at a distance of up to ten meters.

White Spaces: The Radio Evolution
Tuesday ‐ 09/13/11 • 3:30-‐4:15pm
Brough Turner , Founder , netBlazr.com
Smart antennas and smart radios, Cognitive Radio and Beam Forming are on the verge of being incorporated into product. As we head toward these technologies, the opportunities exist for new models of service sharing and interconnection to deliver broadband solutions.
My presentation of netBlazr at Emerging Communications 2011 held at the SFO Marriott June 2011 in which I presented the background (why something like this is needed), the way we disrupt the existing duopoly and pull an end run around the phone companies, the cable companies, the FCC and Congress; and an update on how far we've gotten in our first 12 months.
Although I have high hopes for TVWS I also expect that, 10-20 years from now, we will look back on the TV White Spaces decision and recognize it as a breakthough in getting access to all otherwise unused spectrum, for example in the 3 GHz - 9 GHz range.
My keynote address at the 2003 Spring VON conference, presented on April 1, 2003. I pointed to real 100/100 Mbps Internet connectivity (deployed in 1999-2000, in Ulmea Sweden) emphasizing this was only possible by getting control of local fiber away from the incumbent PTT.
A Wireless Tipping Point, Open Spectrum ImplicationsBrough Turner
As presented at eComm Europe, October 2009.
Are we using radio spectrum efficiently? No. Is this likely to change? Not soon.
"Smart" radios have the potential to support much more efficient and productive use of spectrum, but spectrum regulation is a political issue with well established stakeholders. What's more, our limited experiments with commons-based spectrum management have had widely differing results: WiFi, enormous success; UltraWideBand, disappointment.
WiFi's success happened in "junk" spectral bands where established players weren't interested. That will be difficult to repeat, but Brough will describe some very simple physical principals of radio propagation which, when combined with the next five years of Moore's law progress in semiconductors, suggest a path forward that's very different from TV white spaces. Indeed, the most important result of regulatory decisions on UltraWideBand and TV white spaces is they validate the concept of secondary access.
New Applications and New Business Models
Whether it's LTE or WiMAX or local WISPs using combinations of Wi-Fi, WiMAX and other technologies, we are on the verge of having affordable mobile broadband in the US (it's already available in the UK and Scandinavia and becoming available elsewhere in the EU). What services can be provided over the top and what services need or can benefit from operator capabilities (QoS, security, ...)? The iPhone store, Android store and similar initiatives suggest power is shifting away from the operators and into the hands of application developers and the end user. How can operators leverage their core capabilities (QoS, security, billing, customer relationships, call detail, ...) to provide applications and remain relevant to their customers?

Open Spectrum - Physics, Engineering, Commerce and PoliticsBrough Turner
The Open Spectrum Potential for Evolutionary and Revolutionary Technology and Business Solutions
by
Brough Turner; Founder and CTO at Ashtonbrooke and Chief Strategy Officer at Dialogic
Presented to the Boston chapter of the IEEE Communications Society, May 14, 2009.
In November 2008, the FCC voted unanimously to permit unlicensed wireless devices that operate in the empty "white space" between TV channels. Their “TV White Spaces” decision was the culmination of many years of proceedings, but it's just one step in a much larger discussion, commonly referred to as “Open Spectrum.”
Our use of radio spectrum is regulated under principles that were established in the 1920s, when radio spectrum appeared to be a scarce resource and frequency was the only reasonable basis for allocation. Today’s wireless technology vastly exceeds anything imagined in the 1920s and from physical principles we know that many, many orders of magnitude further improvement are possible. Already the application of new approaches in just a few slivers of spectrum has fostered new industries – WiFi, Bluetooth and more.
The presentation discusses the predecessors, potentiality, and directions for Open Spectrum. This will include:
A brief history spectrum regulation from before the Radio Act of 1925 to today.
Results from measurements of actual spectrum utilization in New York and Washington DC.
An overview of "Open Spectrum" experiments to date, including “license exempt sharing” in the 900 MHz, 2.4 GHz and 5 GHz bands and different forms of "secondary use" including UWB, 3650 MHz and now TV White Spaces.
The physics of propagation and its impact on the range of White Spaces services vs. WiFi, WiMAX, 3GSM and LTE.
IEEE 802.11y protocols and the prospects for expanding secondary use beyond TV White Spaces.
Brough Turner is founder and CTO at Ashtonbrooke and Chief Strategy Officer at Dialogic. Formerly he was founder and CTO at Natural MicroSystems and NMS Communications. He speaks and writes on a variety of communications topics including 3G and 4G wireless tutorials. He presented most recently at the 4G Wireless Evolution conference in February.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.
Let's dive deeper into the world of ODC! Ricardo Alves (OutSystems) will join us to tell all about the new Data Fabric. After that, Sezen de Bruijn (OutSystems) will get into the details on how to best design a sturdy architecture within ODC.
Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.
