Quixoticity?
What are our biggest challenges today?
• WORLD– Our world is changing– Our world is growing– Our world is shrinking
• ENERGY– Energy use continues to rise– Traditional energy sources are declining– Alternative energy sources are hard to store
• INFORMATION– Information is growing– Noise is growing– Meaningfulness is declining
In order to save our WORLD,we need to use
ENERGY & INFORMATION more efficiently
Once again, a time of crises
• “A crisis is any event that is, or is expected to lead to, an unstable and dangerous situation affecting an individual, group, community or whole society” (WIKIPEDIA)
• “The real barrier of capitalist production is CAPITAL itself” (MARX, CAPITAL)
• “Capitalism is by nature a form or method of economic change and not only never is but never can be stationary.”
• “Creative destruction – the essential fact about capitalism” (SCHUMPETER – CAPITALISM, SOCIALISM & DEMOCRACY)
Financial crises…..
Institutional crises….
Natural disasters…
By the end of this century, financial loss caused by natural disasters alone will rise to $185 billion every year, even without factoring in the impact of climate change. (UN, World Bank, 2010)
Man-made disasters…
•The direct cost of the September 11 attack has been estimated at somewhat over $20 billion. Amy Zalman, Ph.D., •The most recent report from Brown University said the total cost for wars in Iraq, Afghanistan, and Pakistan is at least $3.2-4 trillion.
= Human misery
What price a human life? Human suffering?Cost-benefit analysis? Net present value?
% growth/decline in human suffering?
What price safety & security?
We are (have been) moving from one kind of economy to a new one – THE INFORMATION AGE

A biological model
Spectrum
The rise of “cellular” networks
Information goes mobileCoverage v capacityLarge cells – coverageSmall cells – capacity, indoor, fixed substitutionFrequency coordinationAnalogue > Digital > DataTrade-offsHandover/Roaming/Cell-edgeSpecializationUbiquitous GSMPatchy UMTSRapid transformation of daily life, workFrom 0.1% to 100% penetration in a generationSource of innovation & creativity
The rise of standards (communities of interest)
• International Telegraph Union set up in Paris in 1865 > telegraph > telephone > radio > broadcasting > Internet….
• Early LMR – bespoke solutions unique to each customer• A small no. of national suppliers gain advantage• Regional coordination > global coordination of
frequencies, technology standards• Regulation/deregulation• Monopoly > market competition• Mobile telephony
– Exponential growth– Roaming– Interoperability
• ETSI, TIA etc.• Battle for dominance
– GSM v TDMA v CDMA > GPRS/EDGE/3G• 3GPP > Releases 99/4/5/6/7/8/9/10/11/12…• Rapid evolution towards…
(Long Term) Evolution
• 3GPP – 6 partner org. with 350 active participants• Complex working group structure – 150+ meetings/year• LTE enters at Release 8 – MIMO, 64QAM etc.• Faster data speeds than HSPA+• LTE-Advanced (Release 10 >) meets 4G criteria• SAE – flat, all-IP architecture (EPC - evolved packet core)• Need to interwork for several years with 2G/3G• VoLTE/CSFB/IMS – a lot of acronyms
LTE-Advanced:• Carrier aggregation• Advanced MIMO• HetNets• Better cell-edge performance• Mobile relays• No support for key PMR features• (Release 12 vital to industry long-term interests)
“Bio”-Diversity
• No one company can develop a mobile standard by itself
• A global mobile communications standard is a “complex organism” – enormous feat of cooperation
• 3GPP has 403 members – from A (Aalborg University) to Z (ZTE Corporation) and every letter inbetween (except X!)
• Standards have a wide range of possible technology options to choose from
• Each “component” of a standard is a thriving industry by itself with larger & smaller players fighting for dominance and survival
• Even as one global mobile broadband standard emerges – i.e. LTE – players in other industries such as broadcasting, networking, content, vertical markets etc. bring their own IPRs to the table – historically very different industries converge in the information age
• Even apparently strong, dominant standards are vulnerable to changing market conditions & can be abandoned by members in favour of others

Symbiotic Ecosystems
• A small number of “kings of the jungle” in each industry
• However, a single dominant player can slow down progress in an industry
• Successful standards encourage numerous start-ups• Successful standards produce virtuous cycles of
growth and innovation• Start-ups are often spin-offs of larger companies• Global economies of scale demand strictly enforced
interoperability regimes to satisfy users• Mergers & acquisitions can re-invigorate technologies
as long as competitive environment is not affected• Need for a sensible, global IPR environment• Constant interaction with “neighbouring
environments” – “cross-pollination of ideas” – i.e. IPTV, mobile Internet, YouTube, social media etc.
• Apple, Google, Microsoft, Cisco etc. compete in multiple markets and bring market power and valuable funds to develop new “mutations”
Competition v Cooperation
• “Competition is good”• “Cooperation is good”• Contradiction?
• Companies need to know when they should compete & when they should cooperate?
• Game Theory has evolved during the 20th century to provide a growing set of information-rich standard solutions to particular problems/challenges faced by participants competing and cooperating in complex markets
• Negotiation – strategies, coalitions etc.• Discovery that most markets do not tend towards
equilibrium• Multiple equilibria are the norm (Thank God!) – this
makes it harder to find a solution but allows for a much richer environment for new ideas to flourish
• Expert advice required to find right balance between competition and cooperation
The rules of the game – mechanism design
• Government – balance of powers• Institutions - Legislation & Regulation• Spectrum auctions - Optimal allocation of scarce resources?• Each “player” should have the right incentive to “play by
the rules”- i.e. it should not pay anyone to cheat• Fair voting systems• Perfectly functioning markets
• Very, very hard to design the perfect mechanism to achieve best possible solution for society:
– Lobbying– Concentration & abuse of power– Monopolies– Rent-seeking– Freeloaders– Externalities– Transfer pricing– Information asymmetries– Unequal initial allocations etc. etc.
Critical Communications
Life-blood of new 4G/5G economy
Current state of critical communications
• Narrowband, spectrally efficient, professional comms• Accelerating migration to digital• Variety of solutions/technologies/standards to suit user needs• Number of PMR users continues to grow world-wide• Many professional users who signed contracts with
commercial operators over past decade or so are coming back to PMR because of unique value proposition
• Special features:– Security– Emergency button – man-down– Availability– Redundancy and resilience– Direct Mode Operation– Efficient, instant group calls
• Data applications growing – but voice is still critical app.• Greater integration with commercial networks• Rapid innovation in advanced control room solutions• Looking at mobile broadband options – working hard to
influence global standards processes
Who are critical communications users?
Critical communications v commercial communications
• One of a number of “false dichotomies”• Not either/or – priority of one over the other – in a
4G/5G world all communications becomes critical• Emergency services must be provided with the most
advanced communications tools to serve society & achieve public service targets
• Critical national infrastructure supports the emergency services & provides infrastructure for the new society & economy, where we all live and work
• Emergency services must be able to talk to each other & to the public (when required)
• The public must be able to talk to each other & to the emergency services (when required)
• It is government’s responsibility to allocate resources (i.e. spectrum) in a responsible & sustainable manner in all its citizens’ long-term interests
• A strong critical communications sector together with a strong commercial communications sector will provide solid foundations for the future (Smart Cities with Smart Governments, see later slides)
Public sector v private sector
• Another false dichotomy• A number of fundamental goods/services are provided more efficiently by the
public sector, including defence and public safety• Most goods/services are provided more efficiently by the private sector• At different times, in different places, different solutions required• Open societies require strong public & private sectors• Private enterprise tends to thrive in markets where price information allows private
individuals & families to make decisions which do not seriously affect well-being of others
• The public sector steps in in the case of “market failures” (a long list!)• There used to be private police forces, fire brigades, ambulances etc. (in some
cases, there still are!) – private utilities – good idea?• Each society has to decide priorities – security, fairness• Each society has to decide how to allocate resources• Each society has to solve its “coordination problems”• Government sets the rules; tends to be less innovative• Regional/global agreements for harmonised solutions • ICT solutions - greater transparency, better access to information • Public-private partnerships – “smart” contracts
Social value v economic value
• When did the economists take over?• Equity markets; Speculative finance• Short-term investments > culminating in high-frequency
trading algorithms• Social projects (including the finance of critical
communications networks & services) need to look at long-term benefits – outcome for society as a whole, rather than prioritising small subset of individuals (i.e. shareholders)
• Basic human nature: conflict between instant personal gratification and long-term interests of the species
• Following the recent global financial crisis, an increased awareness that financial markets have their limitations – urgent need to separate out important socially-valuable uses of money from “speculation” (& outright criminality)
• Economic activities are those that can be measured• Social activities tend to be “more valuable” at a human level
& in the longer term, but difficult to quantify• The destruction of both types of value has serious
consequences• Big role for governments; global institutions (UN, G20, ITU)
New economy – new forms of value
• There are many “currencies” in the world• We seem to have spent most of the 20th century obsessed
with one particular form – money• Security is a kind of currency – the problem is that it can
only be measured “negatively” (i.e. when it’s lost!)• People value lots of” things”/experiences: hobbies,
charities, shared experiences, respect for nature, traditions, culture, art, science, knowledge, wisdom
• The new economy is struggling to find more ways of expressing & “quantifying” these kinds of value
• Ironically, as we get “richer”, we start to substitute our “money credits” for other more fulfilling & satisfying experiences
• Start recovering the notion of Wealth as a “means” to achieving certain goals, not as an end-in-itself
• Governments must look for more ways of allowing shared value/social value to emerge within the structure of the new economy
• There will be a need to finance very sophisticated critical communications networks which keep up with commercial market trends
Smart Cities
• The space where the majority of mankind will live during 21st century• They have to be self-sustaining• They have to provide for a growing population: humans, robots & machines• All services need to be interconnected & interrelated for greater efficiencies• Extreme inequalities will be harder to justify & probably no longer tolerated• Only sustainable through renewable energy sources – strict pollution-reduction
programmes will be enforced• Smarter use of spectrum in order to cope with data overload• Integrated public safety, public health, basic services, transport sectors with
seamless communications• Those city authorities that start programmes early will generate large amounts of
information so that experiences can be either copied or rejected• Smart Cities will evolve over several decades• Smart Cities will compete against each other• Smart Cities will take resources away from Dumb Cities• Global regulation will be required• Networks of smart cities will challenge the Nation-State• Large corporations will try to control data flows• All communications will be CRITICAL
Smart Governments
• Traditional institutions are in crisis• The information age opens up Government & challenges authorities
of all kinds• Marginal groups can become empowered – better democracy?• Smart Governments need to keep their people safe; provide the
right conditions for growth & development• New technologies create new opportunities• New technologies create new threats• Governments need to be accountable; need to make decisions
faster & need to provide solutions to the main “coordination problems” encountered by society
• Powerful, secure, modular critical communications platforms must be put in place for the common good
• Smart Governments will work with other Smart Governments, studying best-practice & benchmarking themselves against the more successful authorities
• Smart Governments will evolve over several decades• Smart Governments will compete against each other• Smart Govs will take resources away from Dumb Govs• Global regulation will be required
Better Use of Energy/Information
• At a certain level, the world can be reduced to the relationship between energy and information
• Our struggle for life & continued prosperity on this planet comes down to our sustainable use of energy and information
• After over 2 centuries of increasingly less sustainable use of energy and the exponential growth of information & noise, pollution levels are at an all-time high
• The growth of the information age is our response to previous crises• A new approach to energy and information must be our response to the current
wave of crises• Digitalisation and virtualisation have the potential to improve our lives• Modern communications solutions are complex networks• Complex networks are subject to inherent risks• Security & resilience must drive the 4G/5G debate• We need to fight for key critical services• Governments must carry out full risk assessments• Sufficient spectrum must be awarded to critical comms• Regional/global harmonisation must be final goal• We must use less energy to provide better information
Back to spectrum…
Who uses/needs it, why &how easy is it to coordinate?
Global framework
• ITU – founded in Paris in 1865• United Nations agency since 1947 based in Geneva• Over 700 public/private members from 193 countries• ITU-R – Radiocommunication Sector – manages radio-
spectrum & satellite orbit resources• ITU-R responsible for World Radiocommunication
Conferences (WRC)• No global alignment of spectrum allocation• World divided into 3 regions: roughly: EMEA, Americas,
Asia-Pacific• WRC-07: revised UHF spectrum allocations to IMT –
“Digital Dividend” – Regions 1+3: 800 MHz (some 700 MHz in Asia); Region 2: 700 MHz
• WRC-12: Surprise 2nd Digital Dividend in Region 1 proposed by MEA to be discussed at WRC-15 – initially opposed by CEPT
• Interesting for PPDR community: AI 1.1/1.2/1.3• In case of Europe - CEPT:
– Conference Preparatory Groups (CPG)– European Common Positions (ECP)
Radio spectrum allocation categories
• Aeronautical mobile• Aeronautical radionavigation• Amateur• Broadcasting• Fixed• Land Mobile• Maritime Mobile• Maritime radionavigation• Meteorological aids• Mobile• Radiolocation• Radionavigation• Standard frequency• Earth exploration satellite• Intersatellite service• Meteorological satellite• Radioastronomy• Radiodetermination satellite• Space operations / Space research
LTE bands
The UHF traffic jam
• Prime estate – limited resource (the Manhattan & Hong Kong of radio-spectrum world)
• 3G frequencies were freed up in 2GHz band – coverage challenges• Digital dividend frees up 700/800 MHz bands for mobile broadband (i.e. LTE)• Broadcasters getting squeezed as digital TV requires less spectrum than analogue• Second digital dividend in EMEA creates new headaches• Serious possibilities of interference when broadband subscribers really get going• Legislators/regulators trying to find the right balance between needs of mobile
operators, broadcasters, wireless microphone operators, low-power White Space/cognitive radio technologies and PPDR/emergency services/CNI
• Last opportunity in a generation to find dedicated spectrum (preferably at least 2x10 MHz) for critical communications users in sub 1 GHz bands
• Can spectrum be shared?• Will technologies converge?• Is LTE possible in 400 MHz?• Protect existing narrowband• Global giants watching on• Potential for M&A activity
Spectrum auctions
• Step towards “market-based” spectrum management• Since 1994, FCC has carried out 87 spectrum auctions raising $US 60
billion for US Treasury (not all collected!) • In 2000, the UK Government received over UK£22 billion from the
auction of 5 3G licences – winning bidders took on excessive debt & 3G coverage in UK remains patchy 12 years on
• Participants tend to pay too much for prime spectrum (winner’s curse) and too little for spectrum in low-density geographical areas
• Highly complex structures devised to avoid collusion & other “market failures”
• Highly paid activity for Game Theory experts!• A good idea when participants know what they are buying & can afford
to pay – in many cases, auctions are the right solution• Auctions fail spectacularly when massive hidden value for one
participant (i.e. critical communications users) cannot be appropriated by society
• Rigid, flawed economic theory is no substitute for strong political will to make the best decisions for society as a whole
• WARNING: In the USA, funds for FirstNet’s roll-out depend upon the success of future auction processes (see separate slide on USA/Canada)
Critical communications – general requirements
• Security Backward compatibility• CoverageControl room integration• Control Recovery plans• Availability• Interoperability (network, device, application)• Dynamic prioritisation• Resilient operations• Hardened sites…
• Voice (and increasingly, data)• Instant Push-to-Talk• One-to-many communications• Device-to-device communications…
• Messaging• Location• Database access• High-speed data? Internet/Intranet access? Video?...
Critical communications - specific requirements
UTILITIES: FIRE/OIL & GAS/MINING:• Telemetry/SCADA IS radios (IECEx, ATEX)• Teleprotection Bright display• Smart Grid Large keys• Low latency IP67• Distributed control Monitors/sensors• Mains power independence Man-down
Downloadable plans/mapsTRAINS:• Remote diagnostics• Real-time passenger information• Tunnels/underground coverage• Video surveillance• Ticketing• CBTC
USA & Canada
• USA – Largest LMR market in world; still mainly analogue• Long process of rebanding in 800 MHz due to interference• Long process of narrowbanding (12.5 kHz) below 512 MHz – 1/1/2013• P25 – interoperability standard for public safety (Phase 2 delayed)• DMR becoming popular; TETRA now available in USA/Canada
• Leading the way in Public Safety Broadband:• NPSTC/NIST chooses LTE as PS Broadband standard• In February 2012, Federal Law awards D Block to PSBN – 2x10 MHz in
700 MHz band• $7 billion awarded for nationwide rollout by FirstNet• First meeting of FirstNet Board in September 2012• PSCR, Boulder, CO., R&D body – PSS LTE requirements in 3GPP• Industry Canada – final consultations on D Block – probable allocation of
2x10 MHz in same bands as USA• Still working on business case; no clear decision on mission-critical voice
over LTE; commercial carriers oppose utilities/rural broadband• A long way to go before PSBN is a reality, but some key decisions already
taken
Asia-Pacific, inc. Australia
• Largest region – growing number of Japanese, Chinese, Korean manufacturers of PMR equipment
• Large number of digital TETRA/P25/DMR networks• China has chosen PDT for critical communications; TETRA for
largest cities• ITU-R Resolution 646 (WRC-03) identified 806-824/851-869 MHz
for PPDR in Region 3• 700 MHz band assigned to mobile broadband across the region –
being auctioned off to commercial carriers (no global harmonised PPDR spectrum will be available)
• 900 MHz also available for mobile broadband
• Australia - recent decisions by ACMA to support public safety:• 2008: reforms in 400 MHz band – exclusive use of spectrum for
narrowband emergency services (TETRA, P25)• October 2012: 2x5 MHz in 800 MHz band for nationwide PSMB 4G
data network (Is this enough?) – precise band not defined – somewhere in 803-960 MHz band (regional interoperability?)
• At the same time, 50 MHz of spectrum made available in 4.9 GHz band for Public Safety Agencies (PSAs)
Europe
• Large number of nationwide/regional TETRA networks deployed (TETRAPOL in France, Spain, Switzerland, Czech Rep.)
• DMR growing quickly• Rapid migration to digital helping growth in PMR industry• Lack of frequencies in metropolitan areas• CEPT PT FM49 Project Team set up in 2011 devoted to
broadband PPDR spectrum• Radio Spectrum Policy Programme approved in early 2012 with
inclusion of PPDR/critical communications• First Digital Dividend 800 MHz auctioned off to commercial• WRC-12 adopted resolution for co-primary mobile allocation in
694-790 MHz in Region 1• Proposal by several critical comms suppliers for 2x10 MHz to
be awarded in lower 700 MHz to PPDR Broadband• Norway proposing lower 700 MHz for PPDR• Still a long way to go• Europe in danger of falling a long way behind
& destroying growth prospects of “new economy”• Need for a political decision
TCCA CCBG
• During my presentation last year I announced the TETRA Association’s name change to TCCA
• In March 2012, a new group was created within TCCA: the CCBG (Critical Communications Broadband Group) to lead the way in the gathering of requirements and drive for global technology standardisation & spectrum harmonisation
• Its first Chairman is Tony Gray, who will speak to you tomorrow• TCCA has reached out to other influential groups in global critical communications:
3GPP, NATO, UIC, E-UTC, NPSTC/NIST, CITIG/CATA, APCO International, Tetrapol Forum
• CCBG has held 4 plenary meetings so far • Approx. 50 active members – all volunteers• Working Groups:
– User Requirements (WG UR)– System Architecture (WG SA)– Strategic Case (WG SC)
• TCCA is no longer just TETRA – inclusive, cooperative model• CCBG is open to all TCCA members• Tony will tell you more about it tomorrow
Wrap-up
Critical communications – vital for sustainable economy
• Growing imbalances and inequality in the global economy threaten social and political stability
• What price safety & security?• Critical communications generates huge social value • Critical communications needs enough spectrum now for
all current & future needs for a generation• Smart Governments will rely on Critical Communications
to protect Smart Cities, networks • A strong critical communications sector provides the
conditions for the growth of a vibrant private, commercial sector
• The Critical Communications industry is too fragmented; it needs to unite, cooperate & forge symbiotic ecosystems
• The current crisis is an opportunity to move to a new economic model based on better provision of health & education leading to innovation and the better use of information using less energy – all communications becomes critical – better opportunities for this industry
The information age
• We are moving from one economic model to another one• The new economy creates a new economic order• The new economy will create new institutions• The new economy will create new forms of value• The crisis is an opportunity for massive change • We are generating more data than can ever be processed• We are becoming more mobile, informed & manipulated• Trust and respect for traditional institutions are being
eroded• As we become more “materialistic”, the material is
vanishing; we no longer “possess” anything• We will need to find better ways of using energy and
information• Information is not knowledge; information is not wisdom• 4G is not the “end-game” – just the beginning• We have a long way to go & difficult choices to be made• We must remain vigilant in order to remain free
Beyond bits & bytes
• We live in dangerous times• Increasingly complex technology must be under our control • We need to legislate to protect our environment for future
generations• Diversity needs to be protected & celebrated• We need a new global IPR regime to encourage innovation
& avoid parasitic behaviour• We need to find new ways of “measuring” social value• We need to decouple “casino finance” from the real world• We need more global regulation to avoid large corporations
hijacking Smart Cities agenda• Human intelligence is required to curb the excesses of big
data, business analytics, automated trading etc.• We need to recognize that all communications is critical &
build adequate safety measures into all technology standards before they are released (similar to new drugs!)
• We need to regain our optimism for the future, stop stupid austerity measures imposed by global capital, unlock social value & encourage young people to explore new worlds
The human condition
• We have come on a long journey• We are the custodians of the world• We are part of the natural cycle – there is no escape
from this reality• Our restless animal spirits drive us through cycles of
excessive optimism followed by excessive pessimism• Economics is an embodied state-of-mind not an
indifference curve• Society is not a collection of isolated individuals• Unfair societies are not sustainable in the long term• Respect & trust are important currencies in an
advanced open society• There must be a deeper meaning to our lives• In spite of our constant failures through the ages, we
must continue to attempt to design better social systems
• There is no going back – we must embrace the future• As Steve Jobs once said: “Stay hungry, stay foolish”• “Stay quixotic”
The struggle continues…
• Workers of the PMR industry unite!
• We shall never surrender!
Thank you …for staying awake
