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.

The Open Spectrum Potential for Evolutionary and Revolutionary Technology and Business Solutions

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.

Title:
“Hybrid communication systems, FSO/RF and RoF: reliable and scaled communications anywhere”
Abstract:
Current network and telecommunication systems are required to provide higher data rates in access
networks to an increasing number of users. This fact is mainly due to the increase in the Internet
traffic data, which is related with the higher demand of online added-value online content, as a result
of a society increasingly more interconnected. New emergent radio technologies play a key role to
supply these high-demand services to customer, e.g., UWB, WIMAX and LTE-advanced. [1-3]
How to carry them to final customer? How to backup these services?
Free-space optics (FSO), Radio-over-fibre (RoF) and RF/FSO Hybrid communication systems
become a solution to deploy these services on indoor/outdoor scenarios avoiding architecture
problems on WAN environments, e.g., university campus, companies’ parks [4]. Moreover, these
systems will fit emergency scenarios, e.g. earthquakes, tsunamis, where the classical
communications infrastructure cost and time replacement is very high [5]. On the other hand, the
implementation of RF/FSO or RoF systems are enclosed in the new green communications issues,
because they share the common goal to implement energy efficiency communications at anywhere
scenario [6, 7]. Therefore, emergent radio technologies and their application on FSO and RoF
systems are a challenging research issue nowadays.

Practical fibre Optics for Engineers and TechniciansLiving Online
The Fieldbus and DeviceNet standards are also becoming a standard at the field and instrumentation level, and are replacing the traditional approaches in the plant today. Ethernet is fast becoming the obvious choice for industrial control networking worldwide.
While the basic structure of Ethernet has not changed much, the faster technologies such as fast Ethernet and gigabit Ethernet have increased the complexity and choices you have available in planning and designing these systems. There has also been a convergence between Fieldbus and DeviceNet standards in that they are also increasingly becoming based on industrial Ethernet for the higher speed data transfer applications.
There is a fair degree of confusion about where Fieldbus, DeviceNet and Ethernet, are applied and the workshop commences with a clear comparison between the different standards and where they are applied. The first day focuses on AsiBus, DeviceNet, Profibus and Foundation Fieldbus technologies in a simple and understandable manner.

The Internet backbone consists of just over 6000 independent networks that exchange traffic in fashions that are not well understood outside of the backbone networking community. We explain how it works, how it has evolved and how it is continuing to evolve today.
This is a revised and annotated version of material most recently given as an invited presentation at OFC 2014, the optical fiber conference in San Francisco, in March 2014.

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.
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.
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.
As presented at the 4G Wireless Evolution conference in Miami, January 22, 2010.
WiFI has been at the heart of the change to OFDM and MIMO solutions. It is not suprising that WiFi is a hotbed of innovation in today’s marketplace. This discussion looks at the current and future opportunities associated with WIFI and the implications for new kinds of deployment and adaptation by the LTE and WiMAX community.
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?
How the history of cellular technology helps us understand 4G technology and business models and their likely impact on wireless broadband
Including:
Brief history of cellular wireless telephony

> Mobile core network architectures
Demographics & market trends today

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).
Speakers:
Bob Boule
Robert Boule is a technology enthusiast with PASSION for technology and making things work along with a knack for helping others understand how things work.

Securing your Kubernetes cluster_ a step-by-step guide to success !KatiaHIMEUR1
Today, after several years of existence, an extremely active community and an ultra-dynamic ecosystem, Kubernetes has established itself as the de facto standard in container orchestration. Thanks to a wide range of managed services, it has never been so easy to set up a ready-to-use Kubernetes cluster.
However, this ease of use means that the subject of security in Kubernetes is often left for later, or even neglected. This exposes companies to significant risks.
In this talk, I'll show you step-by-step how to secure your Kubernetes cluster for greater peace of mind and reliability.

26. TVWS – Beach-front Property?
MIMO antenna separation
>= ½ wavelength
2.1 meters at 70 MHz
21 cm at 700 MHz
But
2.5 cm for 5.8 GHz Wi-Fi
D-Link DAP-2553 Wavion Networks

27. Multiple radios per chip
Like CPU cores … Intel
2x2 MIMO – 2008
4x4 MIMO – 2010-11
then
Fujitsu
8 radios, 16 radios?, …
what to use the silicon
for?
Beam-forming ! AMD

30. Gaining spectrum for open use
Seeking only “Secondary access”
No interference with existing users
Geographic database; Listen-before-talk
License-exempt stations under positive
control of a “lightly” licensed station

31. Wi-Fi 802.11y - 2008
Rich protocol set for “secondary access”
31
32. Open spectrum
Wireless tipping point ahead
Focus on spectrum blocks above 3 GHz
More access at 5 GHz (4.9-6 GHz)
Anything between 6-10 GHz
“Secondary use”
Light licensing – 802.11y protocols
