@alanhadden
The Mobile Network >> URLLC 2017 Liveblog: Adrian Scrase. Adrian says before we get into the technology, we
should focus on the economy of 5G and the predicted boost to GDP that 5G could bring - as that's what out
"political masters" are kicking us to get 5G up and running. Politicians see potential for wealth creation from 5G, but
the industry knows that new generations of tech take time - which is why we are seeing telcos push to start now.

Looking forward to an exciting day at #URLLC2017 conference.
Brilliant speaker line-up and lots of familiar faces. Adrian Scrace

The Mobile Network >> URLLC 2017 Liveblog: Back to Adrian who is providing a background on the building blocks
of 5G. He points out that part of the history of 5G lies in its background with emergency services and D2D comms,
and that this is now expanding to a wider deﬁnition of mission critical comms. Here's a quick run down.
For IoT, 5G adds Massive MTC capability and low latency to IoT devices of 0.5-1.0ms.
The automotive industry is faced with a choice, Adrian says, with one being 5G-based V2X as a potential path to go
down. Railways also need highly reliable communications as GSM-R nears end of life. LTE and 5G could do what the
train operators want for connecting trains. Other forms of automation include factory automation, that tends to
work in the ISM band which is arguably less predictable than having dedicated spectrum. Manufacturers think 5G
URLLC could be worth looking at.
Adrian says satellite could be an important part of providing that all important coverage part of ultra-reliable. "As an
industry in the past we have really screwed up with satellite," he said. With 5G the motivation is to put that right - so
non-terrestrial components are an integral part of 5G. "That to me is a real game changer".

The main product of the telecoms industry is incomprehensible
acronyms. #urllc2017
9:36 AM - Nov 14, 2017
Martin Geddes
@martingeddes
The Mobile Network >> URLLC 2017 Liveblog: Summing up, Scrase says security and trust will be paramount for the
end market, and must be built into 5G - "an inherent part of the system design". The story that outside industries
don't trust the mobile industry is no longer true, he says. "We've made incredible progress in getting input from the
industrial sector", he says.

That means 5G is a "huge opportunity" for gains for society.
It strikes me that #5G is the drunk network engineer searching
for his computation keys under the radio lamppost, and
wondering how to upgrade it to a brighter lamp with more
colours. #URLLC2017

* 5G — town of 30k people — creates 300 jobs — $50m value
* City like Chicago — 90k jobs
* 5G addresses new demand that 4G cannot reach
* Mobile broadband not enough — also need massive M2M + URLLC
* Need to talk in same terms across the industry
* ITU deﬁnes the parameters
* We “need to know what we mean for low latency” when we say “under 1ms”
* 1 million devices per sq km
* <1 sec per day when cannot send 32 byte packet over radio path
* Automotive, public safety, factory automation — each have their own requirements
* NFV, MEC — mechanism responses from telecoms
* “Today’s IP is not good enough. We need to do something better.”
* Complex network slicing — hard to implement
* Zero-touch network + service management — very new, many emerging activities
* Police, Fire, Ambulance — broadband — groups of 5k people, device to device, new requirements
* Mission critical video, data — not just blue light services (a small industry)
* Chipsets have to be common — with multiple applications
* LTE cannot do “massive” or “critical”.
* Automotive — 10 years developing own standard

* Huge scale, low component cost
* High-speed trains — GSM-R — end of life
* Looking to LTE+5G
* Functional requirements similar to M2M; done gap analysis
* Initially Europe, then global
* Satellite — 3G poor, 4G missing. 5G new story — will be component, same radio but adjusted. Integral part of 5G
system. Game changer — drones, high-altitude platforms.
* Short timescales: new radio, new core network.
* Don’t mention network management, too complicated for manual way. Automated and zero-touch. Will need AI
to manage network.
* Lacking — security, privacy, trust.
* Careful system design needed to reach full potential.
* 5G is for everyone and everything — driven by industries and beneﬁciaries.
* Agriculture, transport, automation — coming to us. Some missing.

@zahidtg
The Mobile Network >> URLLC 2017 Liveblog: Pierpaolo is pointing out that 5G in 3GPP is much more affected by
use case requirements than previous Releases. It is also speciﬁed to work in a much wider range of bandwidths. Plus
in R16 5GNR will be able to operate in non-licensed spectrum without a licensed spectrum anchor. (the equivalent
of MulteFire in LTE). That will allow different deployments of 5G in private environments.

Slicing feature roadmap in standards firms up, rel15 for the start,
and then lots to do to mature the proposition over next few
releases @5G_NORMA @5g_monarch #URLLC2017

@alanhadden
The Mobile Network >> URLLC 2017 Liveblog: Marchese is moving on to URLLC. He lists out Power Plan and
Industrial internet, 360 video comms, remote control of drones, ground based vehicles and cloud robotics. Ral time
control o vehicles, remote health care, smart grids and industrial control systems as well as critical public safety.
Much of this will require network slicing, as well as new edge network platforms. There's a lot of work to be
addressed in slicing, in orchestration, in federation and in how to select a slice from a user experience perspective.
There's also the key element of security and authentication - adapted for different use cases and for SIM and non-
SIM based applications. Security per slice will be critical to the business model.
Finally - R17 will start in 2020 and will include continuous enhancements but Marchese says Nanocore technologies
and AI will be critical to the fully flexible and automated operation of the network.
* 5G — complete new platform. Bigger journey — digital transformation. Cloudification, appification. New concepts
like slicing. New skills.
* Extended range of QoS values — core network

* Service-based architecture — cloud-ready
* State of the art protocols (HTTP2, RESTful)
* Microservices architecture for core network
* Slicing — multi-tenant, API driven
* Attached without IP address allocation [RINA — association control]
* LTE-M — low priority indicator for delay tolerant device
* Distribute intelligence in network.
* Use cases — robotics, cloud, UAVs, etc.
* How to orchestrate and control slices in a distributed environment
* Single protocol framework — SIM and non-SIM use cases
* Federated network slicing
* Next gen protocol stacks
* Nanocore and AI — eSON [not going to work]

The Mobile Network >> URLLC 2017 Liveblog: As an architect Sutton says he needs to understand where to deploy
enablers for low latency capabilities into the network. So he has looked at latency requirements of certain use cases.
7-12ms for VR and AR, sub 10ms for tactile internet and V2V and 1-10ms for manufacturing and robotic control.
"That's not quite as challenging as it could be," he says. "Everything's not 1ms."

@dinos_kats

The Mobile Network >> URLLC 2017 Liveblog: Quite a technical description of the overall network architecture, the
point of which is to look at latency capabilities across the potential different interfaces. For example, if running
IPSec and encryption on the link between a central and a distributed radio unit - how much latency is involved?
BT's latency modelling shows that estimated latency in round trip time can be 3.2ms and 4.4ms in the access and
the aggregation layers. So the key Question is when will you have a need to distribute content and compute
resources at those layers so they can align with those latency capbilities." So we architect to accommodate that and
implement them when demand is there," Sutton says.
#5G is in denial of a mathematical fact: the user experience is
increasingly dominated by dynamic load (∆Q|V) and not base
delay (∆Q|G) or link speed (∆Q|S). #URLLC2017 #DeltaQ Lots
of V ambitions that cannot ever be delivered with G & S-centric
engineering models.

@3g4gUK

The Mobile Network >> URLLC 2017 Liveblog: "We can have network based low latency services - it doesn't have to
be on the BTS or streetside" - if you are looking at sub 5ms we can do that from a network location.
If you are looking at 1-2ms then we can enable a cell site itself as a standalone URLLC build. That could be at a
factory itself and engineer a solution to ﬁt that market. We do something similar today already in stadiums etc
However the functional decomposition of the RAN introduces a whole host of new challenges.
In my mind URLLC is an overlay that needs to be optimised on top of the base eMBB network and requirements will
vary based on use cases, and within that there are URLLC, UR use cases and LL use cases - each of the three areas
need to be understood and addressed independently.
"URLLC is absolutely vital to us, these are markets we need to be moving into. The opportunity today will only be
constrained by our imagination."
One hour into #urllc2017 and we've heard "performance" once,
and "integration" zero times. But lots of talk about possible "best
case" success modes for latency for AR/VR. Engineering =
quantified safety case. So where is it? #5G

* “CU pooling” “F1 ﬂex” — [MG: I have no idea what they are.]
* IPSec on F1 interface over Ethernet [MG: 2 out of 2 terms I grok.]
* “How much latency can we afford?”
* Optimise overall capacity and performance
* AI + automation opportunity
* “Performance” — [MG: Yay! Someone gets it.]
* 95th percentile of distribution for latency
* When to distribute content — CDN, MEC for VR/AR, compute for factory automation? [MG: How to do this? ∆Q!]
* 50% of content BT serves today is from on-net caches
* Can have network-based low-latency services
* Functional decomposition of RAN — whole host of new challenges.
* Network very dynamic, NFV vital. Softwareisation of network critical for network.
* URLLC is an overlay on base network of enhanced mobile broadband.
* Constrained by imagination. [MG — no, science and maths.]
*There is “UR” and “LLC” — not the same. Address independently.
#5G is trying to do in a complex mobile environment things that
the industry cannot yet do in a far simpler fixed one. Caught
between incompatible "purpose-for-fitness" and "fitness-for-
purpose" paradigms. This won't end well, IMO. #urllc2017

Designing 5G New Radio for mission-critical services
Luis Lopes - Senior Staff Engineer, Qualcomm

Scalable numerology, 5G NR design trade-offs & new mini slot
structure by Luis Lopes, @Qualcomm #URLLC2017
10:25 AM - Nov 14, 2017
3G4G
@3g4gUK
The Mobile Network >> URLLC 2017 Liveblog: Lopes points out that the point of the 5GNR is to enable different
requirements - so very small slots in the scheduling for lower latency, for example, or "traffic puncturing" to
interrupt other traffic with low latency traffic. That's a mini slot that can start at any time and doesn't have to wait for
scheduling and sent while nominal broadband data (with new CGB codes) is ongoing. Again pretty technical but the
point is that URLLC can be supported within that overall air interface.
And he points out that in general capacity goes down as latency drops. Reliability also impacts on capacity. But
Qualcomm has found that wider bandwidths via trunking and multiplex gains can get some of this back. "In a
wideband channel you reduce some of the loss you have realised." Again, to paraphrase: although challenging,
URLLC is achievable.

#5G NR has much more flexible frame structure compared to
#LTE which will allow the ultra low latency flexibility. #urllc2017

soon on a number of scenarios," Lopes says. In the long term he sees sharing of sensor data between vehicles,
trajectory sharing and coordination, local high def maps and wideband positioning. Some of these add a relatively
high throughput requirement to the reliability and low latency requirements.

@dinos_kats
The Mobile Network >> URLLC 2017 Liveblog: First question from the ﬂoor essentially asked how the hell telcos will
do SLA management when there are so many different service and use cases.
The panel agrees that there will be increased complexity. But if a slice is allocated to a use case then the slice is
attached to an SLA, that could give a way forward.
Network Slicing as a Service creates a new business model, the same type as cloud computing did, and telcos will
probably create platforms that tenants can log into, selecting blueprints of what they need in terms of a functional
architecture and SLAs.

Working in ultra-reliable low-latency comms seems to cause one
to wear sombre colours and sober styles. I should have worn my
bright orange ("tomato" officially) jumper, after all. Still, I tried
with purple. Be different if you're a game changer. #urllc2017

* Minimum Service Guarantee — SLA
* Complex challenge — layers of deﬁnition — physical, synchronisation, placement of functions, etc.
* Reliability cannot be disjoined from latency
* <1ms — close to edge — under 150km
* Mobility — makes latency and reliability requirement hard
* Are we talking a few bytes or a few thousand bytes — requirement changes

* Q: How are you going to deﬁne SLAs? A: “We don’t know”
* Slice — minimum SLA attached to it
* Throughput — latency — reliability — mobility
* Time-sensitive networking — 802.1 committee
* The network functions need to be placed close, else the radio effort is wasted
* Lots of open questions and challenges
* Should not fear cloud computing — need to cloudify network
* Can then achieve performance, esp in terms of latency

@zahidtg
The Mobile Network >> URLLC 2017 Liveblog: Erfanian is here to talk about "Enabling 5G Extreme Requirements" .
Cloud RAN is going to be critical, as is the overall cloud transformation in the network.
Speciﬁcally on low latency and meeting reliability he touches on lots of technical points - frame structure, packet
size, channel uses, block error rate, diversity, re-transmission techniques - saying there is still evaluation and
standardisation work to do.
But depending on the use case we put a different trade-off on these above elements in a reconﬁgurable way -
depending on the criticality and cost we can support. So by a use case we look at how we schedule and process an
application that comes in, how do we multiplex and process? And these are Qs that link to low latency and high
reliability and it is still ongoing in R&D.

The telecoms industry *loves* this kind of "zillion PowerPoint
shapes" network slide. They always look dauntingly complex.
But there really is an essential simplicity: all the objects help us
copy information with the impairment of passing time (& nothing
else) #urllc2017 #DeltaQ

* Not just about capacity and coverage, but a wide range of requirements in a mobile + connected society

* Can we get the 5G benefits without a 5G core?
Refreshment Break

The Mobile Network >> URLLC 2017 Liveblog: Most of the morning programme has been based around
understanding the technology enablers and design principles for stitching together networks that can support
URLLC. The afternoon promises more discussion of the actual use cases and benefits to vertical industries of URLLC.
Let’s hope that delivers because right now we need a dose of business reality but also vision and imagination of the
benefits of URLLC.
If you were doing a gap analysis of 5G and URLLC based on what we’ve heard this morning, you’d perhaps highlight
quality of service/SLA management within the network slicing environment. But also... a whole supporting cast of
network functionality, it appears - more granular and flexible service functions, and slicing control, and a
decomposed 5G RAN and core with control &user plane separation. In other words the whole 5G and automated
network transformation piece.
Here's are questions that I think is still outstanding - what are the elements that will specifically lower latency or
increase reliability? And how can they be combined or managed within service slices that verticals (businesses) can
use and make sense of in a business environment?
Right... coffee

The Mobile Network >> URLLC 2017 Liveblog: Mike Short keeps asking what the key enabling technologies are.
To be honest I'm not sure from those answers what the key enabling technologies will be. They will be related to the
use cases in question. They will be standards-based to optimise cost. The architecture itself will play a role in siting
resources. There will be some network sharing.
Moving on, Moderator Mike Short asks what some key network slices might be. Xeuli An says ﬁrst of all they should
be international - so a car moving between countries gets the same level support. She says that Network Slicing can
penetrate a lot of industries - and adds the proviso that there will be private networks as well as public. (I think this is
under-discussed so far, FWIW.)
Short asks about regulation. Xueli An says there is some movement in discussions - for example on network slicing
in net neutrality terms. In China, she says, that's not as strong a point as in Europe and the USA.

Any talk of using #5G for safety-critical systems is presently
unethical. The engineering isn't anywhere near the level
required to make the safety case. As an industry we need to
master mission-critical first. #URLLC2017

performance) has little user value; better to have more
predictable quality, but with higher/wider latency. #URLLC2017

Question to all those at #urllc2017 today - what is the target
ARPU for a low-latency subscriber in #5G, vs. a normal MBB
user?
Given it's likely to be needed only by maybe 0.1% of total
devices, does that imply $10, $100, $1000/mo for a profitable
biz case?

Q Who will build and pay for the networks? Sutton says we are building them already with 4G and then enhance the
capability of that network to support either demand or new monetisation capabilities but the coupling of the two
are essential.

Scrase says you are in fact looking at a very different funding model. If GDP gain is the motivation maybe
Governments need to get more involved. Could overturn our idea of the role of an operator and user. Tomorrow's
operators could be Alibaba and Amazon.
Willcock says that for 5G to be successful we have to look beyond current business models. Operator-vendor-user
won't do it.
Huawei's An says we should engage early in machine connectivity via industrial organisations - and that people in
those industries should think about what the business models should be.
And that's basically it.

* Hard to agree common spectrum
* Means we can try more things — and also do things like cross-border services
* Forces us to learn interworking problems

5G NR radio protocols to support URLLC
Osman Yilmaz - Team leader, 5G Radio Resource Control, Ericsson

Only 40 years behind the curve, telecoms discovers "lean" and
the potential to reduce waste. #urllc2017 #5g
Martin Geddes
@martingeddes
The Mobile Network >> URLLC 2017 Liveblog: Osman is here to talk about radio protocols to support URLLC.
Yilmaz says that the key enablers for URLLC have already been identified within the standards process, and it is the
standalone 5GNR specs that will include URLLC capabilities - out in 2018.
Yilmaz identifies the big three use cases for URLLC - traffic safety and control, industrial application and control,
remote manufacturing, surgery. These are distinct from Massive MTC things such as logistics and smart buildings
and so on.
The most important design targets for 5G NR to meet this multi service requirement follow:
1. To be Ultra Lean - sending only the control messages you need to. So for URLLC will need a lot of control
information so that data is provided in time. So the system should be scaleable to minimise non-user transmissions
where it can.
2. To be forward compatible from R15 onwards.

3. To support multi-connectivity. So a device connected to two access points - multiple transmission points to
improve reliability.
4. Beam-centric communications also helps that by re-using reources.
5. Mini-slots for communication to reduce latency and increase ﬂexibility
6. Network slicing
The Mobile Network >> URLLC 2017 Liveblog: Good from Ericsson - there are indeed levers within 5G NR to pull
that tweak latency and reliability. Things like short transmissions and timing (mini slots) in control messaging can
reduce latency. Don't forget these sit alongside architectural elements like MEC and C-RAN.
For reliability, dual site connectivity, diversity of receive and transmit path and multiple transmission all aid reliability.
And here’s a slide of some use cases plotted by requirements.
Useful summary by @ericsson of the URLLC use cases

* “Radio resource control” [MG: they haven’t grokked the distributed computing bit]
* Ultra-lean — minimise transmissions (signalling + control overhead) [MG: Finally! Applying 1970s theory to
telecoms, only 50 years late to party.]
* Multi-service, multi-connectivity, multi-beam
* Reduce size of radio slots
* One-shot transmission vs many-short transmission vs retransmission
* Single vs joint transmission (one vs many backhauls)
* Need smarter scheduling

support URLLC (and 5G in general) for reasons of security, scale, delay and lots of other reasons. "Legacy network
protocols will not be able to deliver URLLC in the future" is the quote.
But the good news is there are alternatives that are live now... although Smith is not supposed to say what they are.
The ETSI NGP he chairs is looking at manageable discrete steps to show incremental differences - and some targets
could be MEC, Carrier Ethernet, for small steps.
This was really a teaser presentation in a way.

* “We need to talk about TCP/IP”
* Lots of great access technologies
* Superhighways for legacy vehicles

* Any flaws in protocol design increase processing
* Workarounds — layers and shims — increase processing, latency, cost
* More latency = less revenue
* Parameters need to reflect current scenarios
* Gone from 1970s — to 2010s — everything has changed
* Network resource contention — huge number of flows
* AMPS: Addressing — Mobility — Performance — Security
* IP — interface-centic, not app-centric
* Signalling storms
* Performance — TCP congestion control not good, poor throughput for small flows, ridiculously large headers
* Congestion bubbled up from all layers to the application — and a round trip
* Need tighter control loops — at the right layer
* Lots of wasteful retransmissions
* TCP can’t tell layer 1 or 2 retransmit vs loss
* Security — there is none. Need expensive overlays like IPSec. Well known ports are a vulnerability.
* These are not solved by IPv6. Increases header size — wrong direction.
* Semantic info of real estate — bind MAC address — vulnerable data. Anonymise it — more work. BGP becomes hard
to scale in mobile
* Score card for TCP/IP is bad. Going to get worse.
* Future demands — huge change — quantity, quality, endpoints, network attachments
* Just increasing capacity does not solve this problem
* Industry verticals don’t just need 1ms radio, but end-to-end budget for performance
* Four 9s reliability — a worry — and energy industry needs better
* SDN, NFV slicing don’t solve this
* Today’s protocols reduce the value of the network investment
* For URLLC, shims and workarounds will break and fall apart
* Alternatives live now
* Narrowband IoT
* Some secret ones
* Next Gen Protocols — ETSI
* Too much inertia to change Internet in one hit

* Carrier Ethernet, slicing, multi-access edge computing are example applications
* Temp shims to work with TCP/IP

The Mobile Network >> URLLC 2017 Liveblog: Thrybom says 5G can fulﬁl deterministic and more robust capabilities
on the wireless side. The PIMM project (a mining pilot) and TACNET4.0 are looking at 5G.
Future use cases include closed loop control, remote control and mobile workforces.
Reliability and robustness is key, as is safety and security. Positioning is also important in some apps, such as mining.

The biggest challenge is the mindset change on the telecoms side to change from thinking about broadband to
reliability and thinking not about average latency but worst case latency. Any time a packet not meets a deadline
then that's loss, three of those losses then production stops and that's very expensive.
Also in terms of this mindset change, with cloud owners bringing operators into their clouds - how does an SLA
look, and who is responsible if production stops?

The Mobile Network >> URLLC 2017 Liveblog: So the technology Mueller sees as important are (obviously) the new
air interface, plus edge computing where the cloud can come into the factory, and thirdly network slicing. And he
wants to think about slicing in a local context, with the additional need for E2E slicing with very high granularity and
the monitoring of slice properties in real time.

And here it is: the big question is who will operate a 5G network inside a factory in the future. Many factory owners
are concerned to let a MNO inside their production. For security and economic reasons, and also for reliability
reasons. Is there an operator willing to take responsibility for that? Operation of private 5G networks within a
factory environment is a necessity. This could be a showstopper. But factory owners should at least have a choice.
It could also be an opportunity for the operator with the right capability, risk proﬁle and industrial focus.

The Mobile Network >> URLLC 2017 Liveblog: Back to industrial automation and the audience is very keen to
explore the idea of private networks - will operators be cut out as industries self-serve via private 5G networks

slices from an operator, or are operators themselves willing to take on the full responsibility for performance and
reliability in an environment where they don't control all the variables - such as the built environment, where
machines move, what machines are used etc.
Guess what... nobody's sure yet. But for sure there are companies looking at all these options.

He's talking about other areas such as a pianist playing with special gloves that contain sensors so that others can

then experience the performance as he plays it. Or a dance performance that transmits dancers' heartbeats into a
silicon heart that the audience holds.
"So what does this mean for telco infrastructure," he asks. Well, immersion requires 5G. Rates of 1-10Gbps, latency
of less than 10ms, MEC and the IoT.
Hossaini said that 5G also requires immersion. It's a major business driver - with new media formats, new cross-
trained researchers and new production workﬂows in the arts.

challenges. Can 5G solve them? #URLLC2017
Zahid Ghadialy
@zahidtg
The Mobile Network >> URLLC 2017 Liveblog: Long is going to talk about high performance radio communications
- breaking it down into two areas: high mobility and for high capacity.
Long is saying that mMTC and high performance communications applications cannot simply be replicated by non-
telco players - so that gives telcos a good way in which to "move up the value chain".
In the Industrial Internet of Things, high mobility (satellites, planes, vehicles) have very high mobility and range. In
IIoT more likely to see challenges on reliability, systems integration and safety. But both need coverage quality,
security, ease of network management.
Not surprisingly connectivity to high altitude platforms has plenty of challenges. You can mitigate some with smart
antenna technology. For industrial IoT challenges relate to device density - not from a throughput but a
management perspective. Also propagation inside modern factories is a "nightmare". Plus lots of devices sending
small numbers of packets can be very ineﬃcient if sing IP or UDP. Need more eﬃcient protocols to get more data
through the channels.

Mitigation includes SON, interference mitigation, a frame structure to support small packets.

The Mobile Network >> URLLC 2017 Liveblog: Thibault is going to share the findings and proposals of the NGMN
Extreme Requirements Taskforce.
Thibault says the first phase has been to look at fundamental trade-offs when requirements are extreme,which
mainly relates to coverage. The second phase has been to look at deployment models. Ericsson is leading the RAN
deployment model and Huawei is leading on end to end considerations.
There's a final whitepaper due in March 2018.
So what are the effects of making radio requirements extreme? Simply that if we start decreasing latency then
experience coverage loss. So we need to understand that extreme requirements have a huge impact on coverage
area that we serve.
Meanwhile although it looks like we can deliver low latency for small packets in our coverage area, if we use TCP/IP
then the overhead fills up the air interface.

So extreme requirements may require more bandwidth and site diversity, but also lighter protocol stacks might be
needed for delivery of small packets.
The design/operation trading space for ultra reliable low latency
networks. Packet size, reliability, latency, coverage –
fundamental trade-offs. #urllc2017

* Packet size, reliability, latency, coverage — fundamental trade-offs
* If we use a TCP/IP stack, the headers use up all of our resources (lots of small packets, lighter stacks)
* Otherwise the air interface is carrying nothing — just overhead

Yes we have also seen and considered some of these coverage
compromise issues in recent tool based analysis of
requirements in a couple of our projects #URLLC2017

Having taken into account the discussions how do we ensure the URLLC conference makes a difference?
Moderator: Dr Mike Short - Telefonica, Panellists: Ilara Thibault - Vodafone, Andy Sutton - BT, Erol Hepsaydir - Three
UK, Pierpaolo Marchese - Telecom Italia
We can't do automated fault isolation, or scientific allocation of
blame, in well-established services like voice. We're trying to run
before we've crawled and walked with #5G and advanced
industrial use cases. #urllc2017

The Mobile Network >> URLLC 2017 Liveblog: This final panel session is asking: "How do we ensure the URLLC
conference makes a difference?"
BT's Andy Sutton says we've hit on the realisation that the appetite for conversations between telcos and industry is
real.
Thibault says there is a list of verticals that would like to engage.
Moderator Mike Short asks if there is enough flow of ideas. Thibault says one issue is that the vehicle makers are not
used to collaborating with each other.
And here we come to money: Mike Short asks (to chuckles from the audience) if there's any indication that
companies would be willing to pay for the investment in networks for URLLC, or shoulder the risk of technology
change.
Sutton says one thing that did come up is that companies spend a lot of money on services that would be in essence
replaced by 5G and that opens up a potential business case. TIM's Marchese says there needs to be "more flexibility"
in terms of business model between a private enterprise environment and a public environment to make 5G
sustainable.
A question asks if it is in fact established that verticals will look to 5G to meet their needs in this area. Sutton argues
that, to take an analogy, in Narrowband IoT cellular "won overnight" once its benefits had been established. Short
argues that cellular comes with advantages in volumes and economies of scale.
* Not clear to verticals the complexity of managing a network
* If there’s an automotive or industrial accident, who is responsible?
* Who will pay? Industry verticals already spending a lot of previous gen services.
* Is 5G just carrier aggregation and MIMO antennas?

* Government backing critical — money, demand, research
Chairman's Closing Remarks
Dr Mike Short - CBE, Telefonica Europe - Vice President Telefonica
A brilliant conference with brilliant speakers, panelists and
chairs. Dr. Mike Short is always great chair. A day well spent.
#URLLC2017. Looking forward to #URLLC2018

The Mobile Network >> URLLC 2017 Liveblog: And so to Mike Short's summary. We've had 22 speakers and 4 panels,
we've looked at standards, at architecture, 5G NR, we've touched on cost a little, some of the technical trade-offs,
and considered links to key verticals and heard detail on some of those. "Bringing demand and supply together is
not always easy but the conference has tried to do that". The material from 5GAA and 5GIA has impressed Short.
* Balance demand and supply
* Cost an issue
* Trade-offs needed
* URLLC for people vs things — different?
