The 9th International Workshop on Broadband Wireless Access (BWA), in co-location with IEEE Globecom 2013 in Atlanta, US, marked the successful continuation of what has become the most renowned workshops series alongside IEEE communications conferences. The series aims at bringing together leading experts from academia and industry to discuss latest research and trends in a particularly focused and interactive way.

The organizing committee of the 9th BWA has been:

  • General Chairs: Patrick Marsch, Nokia Solutions and Networks, and Andreas Maeder, NEC Laboratories Europe.
  • TPC Chairs: Arun Ghosh, AT&T Labs, Giridhar K, IIT Madras, and Peter Fertl, BMW Group Research & Technology.
  • Steering Committee: Thomas M. Bohnert, Zurich Univ. of Applied Sciences, Dirk Staehle, DOCOMO Communications Laboratories Europe, and Gabor Fodor, Ericsson Research.

This year, the workshop attracted 85 paper submissions, out of which 31 were accepted for publication, yielding an acceptance ratio of 36%. With about 50 participants, the workshop was one of the most successful instances since the beginning of the series.

Out of the accepted papers, 20 were presented in oral form in four technical sessions:
Novel PHY techniques, e.g. looking into novel multi-carrier techniques, modified OFDM approaches or faster-than-Nyquist signaling
Novel MAC techniques, e.g. focusing on scheduling and MAC design in wireless multi-hop or mesh networks
Multi-antenna and cooperative communications, investigating interference alignment, millimeter-wave beam alignment and cooperative relaying
Spectrum, cognitive radio and HetNet, e.g. covering spectrum sensing or power allocation in cognitive networks, or dual connectivity and network selection in heterogeneous networks

The remaining 11 papers were presented as posters, including short teaser talks, and covering a wide range of topics like SON, context-aware mobility management, demand control, propagation and deployment.

The paper presentations were complemented with five invited speeches from renowned representatives of mobile network operators, network vendors and academia. All speeches were focused on the future of broadband wireless access, in particular the upcoming 5th generation of cellular communications.

In the first speech from Hank Kafka, VP Radio Access & Devices, AT&T, already the title “The Next Next Generation” reminded that just lately LTE was introduced as a next generation – and defined by its abbreviation to be of longer-lasting nature – so that the introduction of yet another generation has to be carefully considered. After highlighting the current data traffic growth and consequent network densification, Hank stated future network requirements, like increased spectral efficiency, substantially more devices, and lower cost. He touched potential solutions like massive MIMO or novel PHY and MAC approaches, but emphasized that any non-backward-compatible technology would have to deliver substantial gains in spectral efficiency, throughput and cost to be justified, considering the large recent operator investments into LTE-A.

The next speaker, Bill Payne, VP Small Cells and CDMA, Nokia Solutions and Networks, emphasized the strongly expanded application space beyond 2020. For instance, the Internet of Things with trillions of connected devices and the usage of wireless connectivity for industrial or vehicular traffic automation will offer new business opportunities, but also pose severe novel communications requirements, like latency, reliability or strongly reduced device cost and power dissipation. Bill stated that 5G will require both an evolution of existing technologies like LTE-A and Wi-Fi as well as novel radio access technologies designed to meet the very different nature of future application needs. As examples of such technologies, Bill gave an insight into the novel enhanced local area and mmWave technology NSN has been investigating in the last years.

Gerhard Fettweis, Vodafone Chair Professor, TU Dresden elaborated in detail on the novel use cases that may define 5G, like user-specifically rendered 3D, augmented reality, industry automation for user-tailored products, and traffic control. He emphasized that 5G will be about using wireless communications not only for content, but also for steering and control, and stated the key 5G requirements as throughput, latency and reliability. Gerhard discussed solutions to meet these requirements, such as generalized frequency division multiplexing (GFDM) as an enabler for lower air interface latency. He concluded his talk by pointing out the interesting future question of where in the infrastructure data and applications should reside in the context of e.g. low latency, and the potential necessity to “hand over” applications between network nodes.

Gabor Fodor, Master Researcher, Ericsson, pointed out that network nodes and devices may converge towards similar complexity, and that we will see much more transmission modes beyond 2020, including e.g. device-to-device communication. He emphasized that 5G may evolve from the classically decoupled concepts of uplink and downlink to an optimization of two-way communication incorporating network coding and network information theory. Gabor also touched various other research fields of Ericsson, like massive MIMO, shared spectrum access and mmWave technology.

Chih-Lin I, Chief Scientist Wireless Technologies, China Mobile Research Institute put an emphasis in her speech on the aspect of energy efficiency, and highlighted the paradigm change from designing wireless communications for optimized spectrum efficiency to jointly optimized energy efficiency and spectrum efficiency. She considered “Green and Soft” as the key words for BWA in the future. Specifically, she highlighted 5 key focus areas in China Mobile’s research effort: Rethink Shannon, Rethink Ring and Young, Rethink Signalling and Control, Invisible Base Stations, Small Cell New Spectrum. Chih-Lin also stated massive MIMO and Full Duplex as topics of interest for 5G, and provided some detailed considerations on an irregular antenna array her institute is designing.

The workshop was concluded by a panel discussion among the invited speakers, moderated by Patrick Marsch from Nokia Solutions and Networks. It started with the question which future application requirements would justify novel, non-backward-compatible wireless technologies. The panelists agreed on latency as a clear case, while reliability may be achieved through an evolution of existing technology. Also the need for device-to-device communications was stated, but here the operators commented that the business case behind this was not clear yet. Regarding expected technology disruptions, the panelists concluded that air interface modifications, mmWave technology, system architecture and protocol stack would be most likely fields. The speakers then elaborated on whether there can be a “one-size-fits-all” approach in 5G, able to address all requirement dimensions throughput, latency, reliability and power/cost, or whether there will be technologies optimized for specific use cases. Nobody was able to precisely answer this question, but the operators emphasized the need for compelling business cases to justify dedicated radio access technology only for some use cases. After venturing into the topic of spectrum usage, the panel was concluded with an outlook on how the wireless communications ecosystem may change beyond 2020. It was for instance discussed that network vendors may face the challenge of moving towards a consumer market as the number of base stations starts equalling that of devices, but that edge computing may be a novel business opportunity for both network vendors and network operators.

At this point, we would like to express our sincere gratitude to all persons who have made this workshop a great success, such as the Technical Program Committee which has mastered a total of 255 paper reviews, Matthieu Bloch, Kwang-Cheng Chen and John Barry as the overall workshop chairs for Globecom 2013, which have been very responsive and supportive, as well as the session chairs and invited keynote speakers and panelists.

Special Issue on Wireless Networking for e-Health Applications
The confluence of electronics miniaturization, information proliferation in healthcare, and novel concepts for energy efficiency and energy scavenging, has pushed the application of Mobile Wireless Networks, such as Wireless Sensor Networks (WSN) and – perhaps more importantly so – Wireless Body Area Networks (WBAN) from the realm of theoretical exploration into healthcare reality. This advance heralds in a new era for patient monitoring, medical procedures, patient status awareness, outpatient treatment, and a plethora of other areas in modern healthcare.

Developments in component miniaturization of electronics and sensing devices, advances in low-power wireless communication, and the arrival of energy harvesting have led to the development of ultra-low power wireless communication and sensing devices that are ideally suited for mobile healthcare applications. These devices can be installed in medical facilities and equipment, or worn directly on a patient’s body, allowing for real-time data acquisition, data fusion, reporting, and alerting from a plethora of sources. This allows for an unprecedented level of insight into a patient’s health, with a similarly high level of fidelity of the collected data that in many cases is sufficient to allow biometric identification of
an individual.
With the advent of these new e-Health applications and their associated requirements and constraints, many vital topics of research need to be
explored to provide robustness, security, responsiveness, and longevity of the wireless network and patient health information. This special issue
focuses on the state-of-the-art in wireless networking for e-Health applications, associated technical and regulatory challenges, as well as
exploring deployments and implementations in real-world applications.

About the Conference

Next-generation mobile networks will evolve out of existing wired and wireless networks of different nature by means of convergence, fusion and mutual penetration; next-generation multimedia services in turn pose new requirements and challenges on treatment of traffic within communication systems – a certain degree of multilayer co-operation has to be achieved. This forms a framework on harmonization of results obtained separately in different areas of network research like network performance evaluation, architecture and protocol design, and low layer network design. The conference goal is in the identification, investigation and integration of new algorithms, approaches, architectures, methods and mechanisms to enable proper and efficient operation of a next-generation IP-based wireless network. Therefore, wireless networks and their interaction with wired networks shall be widely examined and addressed throughout the conference.

The history of NEW2AN dates back to 1993, today it is an established conference featured by proceedings published by Springer LNCS (confirmed) and distinguished keynote speakers.

The NEW2AN 2012 will be held in St. Petersburg, Russia – the meeting point of East and West. Through its stunning architecture and wonderful art galleries and museums, among a number of other attractions, the wealth of history of East and West can be seen and felt in this beautiful city.

IEEE Globecom 2010

Schreibe eine Antwort

IEEE GLOBAL COMMUNICATIONS CONFERENCE (IEEE GLOBECOM) is one of the flagship conferences of the IEEE Communications Society and high up on my annual conference must-attends.

This year, IEEE Globecom 2010, is held in Miami, Florida and lines-up seamlessly in the hall of fame of this conference series. With 2500 attendees on-site it sets a new record and as usual it features a very comprehensive program with a good number of high-profile speakers from business as well as academia.

Keynote by Yoshihiro Obata, CTO of eAccess Ltd in Japan
A very interesting talk, excellent presentation with a very good mix of industry/company background/insight and technological/research challenges. This is the style of talks you look for at IEEE Globecom.

Here is what Mr Obata had to tell:

– Traditionally, Telco services were controlled by operators (e.g. SMS). With IP services control moves towards devices/applications
– And terminal are no any longer provided by the operator, huge variety in devices, competition high (e.g. Apple vs Google)

– Smart-phones turn signaling (traffic) into a huge issue for operators. As control went from network to devices operators cant control / police users effectively. This essentially prevents M2M introduction

– Highest expenses are still with the backbone, eAccess flat rate offers were only possible since they own a backbone, especially in wireless networks is the backbone cost what matters; base stations are not relatively inexpensive

– Volume and characteristic of traffic by corporate users does not cause trouble, i.e. corporate users behave as they follow a certain (manageable) pattern (e.g. peak traffic).

– Mobile vs Fixed: The peak (busy hour) in mobile networks is broad (TMB: statistically stationary) versus traffic in fixed networks (ie DSL) shows very sharp/short peaks (instationary) -> TMB: This has consequences to admission control!

– Reasoning: mobile terminals/services are simpler to use, by potentially more singles and younger users, which are attached for longer periods to their terminals; In contrast, Internet services over fixed (cable, DSL, etc) access require a greater effort to start, in particular the terminal (PC, laptop, etc) and hence users start-use-shut.

– On traffic patterns: 300K (2-5%) users take 50% of the capacity for peer-to-peer traffic, still no issue for state-of-the-art technlogy, annoying though, but the network needs to be sized for full capacity anyways.

– On business in general, telcos need to adapt to change as meanwhile nearly 30% of the user spending goes to the terminal and this takes a major part of the overall budget

– A new service in Japan is „Pocket WiFi, WiFi allows terminals to concurrently access the network with one subscription. This gives meanwhile three options for mobile operators – hotspots, mirco cells, pocket wifi – still unclear which will predominate

Kevin Fall (Intel) WSN Forum
– Observation on WSNs – mostly worried with power consumption, use essentially the same network architecture as any other devices, people mostly use them for trivial scenarios (room temperature monitoring)

– Programming WSNs as essembles instead can be a basis for innovative scenarios

– Issues: disconnection, addressing (location/ID, address space)

– Some ideas/solutions: DTN (storage/caching), use URIs for addressing/naming anything

– Info-networking (content-centric or data-centric networking) that put data/information in the center of design, architecture, operations instead of hosts

Edward Knightly (Rice Uni) WSN Forum
Edward, how was giving a keynote at my BWA workshop in 2008, talked about „sensing“ in general and took WSNs into the vehicular, smart grid, and eHealth domain. Nothing really new, some of the slides are indeed known for a while (eHealth). What was new though, is that he is promoting „Visible Light Communication“ as a technology for vehicular communications.

H. Atarashi (NTT DOCOMO) 4G Operator Perspectives
– DOCOMO to deploy LTE comercially in Dec 2010, initially over legacy 3G infrastructure, terminals will support dual-mode

– 3 deployment scenarios, remote-radio-head, cabinet-type, indoor

– Remote radio head: base stations (eNodeB) are deployed somewhere and connect over fiber to the …

– ~1000BS by end of 2010, 5000 by end of 2011, 15000 by end of 2012 (40% POP coverage)

China Mobile
– 564m subscribers, ~500000 GSM base stations
– LTE deployment in 2011, several trials conducted with several manufacturers involved (terminal + network), LTE-TD meets all expectations

COMCAST IPv6 Forum
– CDNs are starting migration strategies this year (2011)
– Mind that this involves many aspects, way beyond the network, e.g. OS, Apps, OSS tools, CRM, Accounting, BSS in general
– To wait is a risk: v6 introduction takes time, Google needed 3 years
– And there will be more NAT to come in the meantime
– But 90% of v6-readiness can be achieved without turning v6 on!
– How to save cost? Put v6-readiness in your product strategy (TMB: that“s easy said ..) and mind that a customer may need to turn NAT on in order to access your content
– But isn“t v6 broken? No, that“s mostly an issue on your consumer-side and mind, ISP-NAT does not scale and add complexity/unwanted control
– The today challenge of v6 is not so much technology, it“s training of field personell, sales, support, etc
– Comcast is virtually v6 ready

Nokia IPv6 Forum
– Symbian is v6 ready since quite a while
– NAT versus v6, keep-alive versus idle but connected -> NAT drains your mobile“s battery
– Operators will not switch on Voice over LTE in the near future
– More details on NAT: keep-alive commonly in 40sec-5min intervals, can decrease your standby time from days to hours, many different/imcompatible tunneling, very different NATs (home, office, hotspots, ISP-NAT, etc) in terms of traversal mechanisms, frequently poor quality code, mind multi-level NAT (cascades)
– T-Mobile and Nokia run v6-trial in the USA, Nokia supports cell+wifi v6 in the N900 dual-stack.

Some random notes
– JND theory, „just noticable distortion“, widely used theory for picture quality evaluation (subjective)

– Wireless network usage is not uniform, one practical example shows 15% of the cells generate 50% of total traffic

– Most of the traffic in the future is expected to come from indoor environments

Mobile Cloud Computing

Schreibe eine Antwort

Is there something like „Mobile Cloud Computing“? (a question I am after since early 2009)

A quick Internet research provides evidence that MCC might indeed get away from being a „bwc“ (buzz word combination) and turn into something substantial.

Fundamental Reflections on MCC
– MCC basic elements: Mobile Device, Mobile Network, Cloud Computing (IaaS/PaaS), Cloud Serivce (SaaS)
– Mobile Devices: The dominant share will remain low-end, with very limited resources
– Mobile Networks: Shannon/Nyquist, channel characteristics/impairments
– Cloud Computing: Depends on communications, provides virtually unlimted resources on-demand, …
– Users look for something that may be called „on-service, on-demand, on-(any)-device“

ICIN 2010 in Berlin

Schreibe eine Antwort

I was attending ICIN 2010 in Berlin. My keynote on „Global Future Internet Research“ can be found on the conference website (link below).

Worthy conference with a good number of talks/attendees. Particularly interesting I found the mixture of people from research and those working on innovation and/or general management.

Few takeaways:
+ IaaS (network+storage+computing) seen as good business model for telcos in the future
+ Value of enforcing an extra revenue share from Google questionable since 25bn (Google) versus 1000bn (Telcos) is peanuts (CEO of Northstream).
+ Appstores/developer communities for telcos of limited value since Appstore mainly a tool for device sales (mobile device manufacturers)
+ Telco““““s shall better look into many smaller business models rather than looking for the next SMS-like killer app (H. Arnold, T-Labs)

The slides of the keynote speakers are meanwhile available for download

I am attending the 1st FUSECO Forum in Berlin, at Fraunhofer FOKUSFUSECO Forum 2010

A few takeaways (slides at download)
HP Baumeister – Fraunhofer Digital Media Technologies, USA
+ Verizon happy to be a „bit pipe provider“ and teams-up with Skype exclusively

Franz Seiser, Deutsche Telekom AG, Germany
+ Deployment (especially integration) of EPC into existing infrastructure true challenge (despite the streamlined architecture of EPC itself)
+ Roaming (in particular IMS roaming) and QoS (different signalling) big challenge
+ Roaming primarily a European issue
+ Challenge with signalling load in LTE due to non-standard conform feature (immediate dormant mode) of smart phones (for energy saving). Operators don““““““““““““““““““““““““““““““““t have any means to control signaling in their networks
+ Another challenge related to signaling is that LTE/EPS uses Diameter exclusively and hence is not simple to integrate into existing SS7-based 2G/3G systems
+ IMS still way too much focused on fixed networks

Giulio Maggiore – Telecom Italia, Italy / ETSI TC INT Chairman, France
+ IMS & EPC Interoperability to be released by ETSI TC INT in 2011
+ Workshop 3GPP rel 8 Implementation, Deployment and Testing, 24-25 Nov 2010, Sophia Antipolis, FR

Industry panel:
Markus Beckmann, Accenture, Germany, Sven Akesson, Ericsson, Sweden, Wolfgang Hummel (Telco SM), HP, Germany, Cornel Pampu, Huawei Technologies, Germany, Bernd Wunderlich (Telco SM), IBM Deutschland, Germany
Thorsten Robrecht (Head of Global LTE), Nokia Siemens Networks, Germany, Alain Dakroub, Tekelec, France

+ NSN: currently has (global) 52% of GSM subsribers and 72% of WCDMA, currently 32 LTE networks globally (LTAM, Asia), Germany also close to forefront, NSN roughly 1M LTE basestations deployed globally, devices are already there and comercially available in weeks/month, 50% of NSNs business is already operating networks, 45K LTE basestations to be deployed by Lightsquared and operated by NSN
+ IBM: Germany decreasing telco market, question what can LTE do to solve this – generate more revenue?, Operators have to operate 2G, 2.5G, 3G and soon 4G networks but revenues shrink (~2 percent), challenge / opportunity is cloud computing for enterprises, OTT-provider kept the consumer based for them
+ HP: Offers a combined HLR+HSS product, better work with OTT (like Goolge) rather to fight them
+ Ericsson: IMS already deployed (mostly in fixed domain), Ericsson has a unit Global Services and running (deploying/operating) already hundreds of networks
+ Accenture: One challenge with these technologies is the process change that comes along with convergence (e.g. by EPC/SAE), massive impact on IT systems, changes needed in ticketing, customer support, OSS/BSS, etc, key element to address pressure of decreasing revenues is out sourcing to dedicated specialists in countries abroad (e.g. India, Asia, East-Europe) – examples engineering, operations (e.g. provisioning in shared service centers) and similar.

Q&A: Shall operators outsource core services like voice? Accenture: better not

M2M Opportunities – Lessons Learned from the US Market
Ronald M. Jubainville, Sprint, UK
+ Sprint SIP-enabled IMS network since Aug 9th 2006, First US 4G network in the US, World““““s first 3G/4G Android phone
+ What matters are devices, e.g. Mobile ATMs (average load per Mobile ATM is 6MB/month)
+ Usage-based insurance for cars with 183M users operational

Alfonso Ehijo, Telmex International, Latin America / University of Chile
+ Verizon does befriend the idea of bit-pipe provider due to compensation by several exlusive partnerships with Google, Skype, and similar content/service providers
+ Relationship (the R in smart) is what really matters (c.f. Verizon)

Roberto Minerva, Telecom Italia, Italy
+ Too many network APIs out there
+ The problem is that Telco““““s are accountable and for that make usage of network APIs complex and heavy
+ Issue is the difference between global Internet services and local communication (network) services
+ IMS will not be able to support services for business services
+ OneAPI is too late
+ Interoperability is an issue for telcos, not the users
+ WebCo(mpanies) are much faster and release alpha versions and by that involve the users early – versus – Telco““““s develop standards over years …

Q&A: There is a big opportunity in the _private_ cloud (Google is not (yet) there) says Sprint

Prof. Marc Drüner, trommsdorff + drüner, Germany
+ Marketing has to go online, „go where the customers are“, people expect the company comes to them,
+ Cool Internet App: Mint.com – manage your financials using the wisdom of the crowds!
+ 75% percent of Indian youth has first contact with Internet via mobile devices
+ Extensive study of Retail Use Cases available by the company

Boaz Zilberman, fring, Israel
+ IMS is a waste of time, too complex, too heavy,
+ Mobile app industry leapfroged IMS

Sebastian Krems, ITCcon GmbH, Germany
+ Wholesale is key to the future and this means partnership
+ Wholesale industry in the telco domain behind to other industries
+ Roughly 250MB of information per year/person, total 1-2extabyte/year
+ Telco industry sustained 50% of price decline/year for the last 30 years
+ Wholesale today: long distance: doesn““““t make a good business anymore -> efficiency and scale are king; access: potential for a long-term business for investors who can sustain a steep ramp-up
+ In the future – wholesale will be all over the place!

Dr. Ralf G. Herrtwich, Daimler AG, Germany
+ The most profitable pieces in a car „integrated solutions“
+ So far web-experience in vehicles are lousy! Network doesn““““t support 200km/h ! – LTE could be the solution

Philipp Freudenberger, SAP, Germany
+ SAP about to take a bold step into the (enterprise) mobility domain (c.f. Sybase acquisition), along with SAP““““s strive for broader adoption of its solutions (goal of 1bn users by end of 2010)
+ Value chains get more and more sophisticated, increasing number of players, stakeholders, – business networks
+ How to make money out of an increasing amount of information? – Example: „from starvation to restaurant to food and payment“, „collaborative eCare“, „utilities – increased collaboration by smart cars, smart meters“, „retail – highly collaborative since customers can use real-time offer/price comparisions“

Closing Note by the Chairman – Thomas Magedanz, TU Berlin / Fraunhofer FOKUS
+ Still many open questions to be answered, especially in view of the more complex value chains in the future
+ Will there be a common platform in the future that supports this value chains and allows for collaborative value proposition?
+ This will be addressed by „Future Internet Research“ !
