Managing Today’s Complex Radio Access Network

The RAN lifecycle typically goes through four phases: 1. Planning/Design/Rollout, 2. Performance Assessment, 3. Network Optimization, 4. Capacity and Small Cell Planning. In phase 1, it is standard practice to start with coverage priorities and then move to capacity.  In order to predict your network coverage with high confidence, it is imperative that accurate RF propagation models be used in the RF planning tool.  With accurate prediction, operators are able achieve tremendous cost savings while meeting network coverage goals.

 

This paradigm holds true in 4G rollouts as well.  However, as the coverage becomes more ubiquitous, the networks are mostly capacity limited.  The focus then shifts to capacity relief in later stages of RAN lifecycle.

 

The advent of small cell-centric 5G will usher in a plug-and-play era for cellular, not dissimilar from WiFi models.  Accordingly, the planning tools and support system will need to evolve and adjust to this new reality.

 

Phase 2 of the RAN lifecycle is about assessing network performance.  You need state-of-the-art tools to monitor the network, and we know how much operators really do rely on these tools. Drive testing used to be sufficient to understand network behavior, but that’s coming to an end, except for truly Greenfield network / radio access technology (RAT) launches.

 

Given that optimization and network expansion rely on it, operators understand the need for a reliable measurement solution.  Entire network.  Real-time.  Live.  24×7. End-to-end. Every single transaction across all services. These are critical in today’s multi-RAT, multi-layer, service-aware, multi-vendor heterogeneous networks.

Future of RAN map

 

The phase three of RAN lifecycle is network optimization.  Today’s state-of-the-art solutions, offer actionable recommendations so that operators do not have to always go look for places to optimize. SON optimization solutions now fully automate that final step.  You need closed-loop automation to detect and monitor, but also to change. Infrastructure is vital to knowing how your system is performing.

 

Phase four in the lifecycle focuses on capacity planning, for which there are two parts. First is the traditional exhaust prediction of each location, upon which usually a carrier add or a cell-splitting is carried out.  Second is small-cell planning?  For example, with Super Bowl 50 in the Bay Area, we saw mobile operators out in full force adding small cells and other solutions and monitoring around the clock. Should they split the macro network? Add small cells? Where? Will the small cells draw the traffic you want? What will it cost? These decisions must be based on data – network intelligence and tools like are indispensable assets to mobile operators.

Future of RAN

 

VoLTE is harbinger of things to come.  For the first time in the history of the mobile network, we have a mixed-QoS air interface. This is a subtle but an important paradigm shift.  Then there is the end-to-end bearer management challenge that did not exist before.  Thirdly, we now have dual control plane system thanks to SIP ‘out-of-band’ call/session control.  All these three fundamental changes require a fundamental re-think of support systems.

 

There are disruptions on the horizon. New spectrum will raise game-changing questions like, how do you plan for LTE on new spectrum? LTE-U and IoT are potential game changers, and many industry trends are pointing to small cells finally experiencing the surge predicted 4-5 years ago, but differently than expected. There are new business models entering the market, and we are all working to stay ahead of the curve and make a difference. Evolution is the key.

Insight: Five Questions About 5G

Guest post by Mae Kowalke, Accedian

Amid all the hype over 5G, it’s good to periodically take a step back and ask some questions about where things are headed for future mobile broadband, and how to get there. Here are five things we’ve been pondering as part of some in-depth analysis into 5G, each with reference to a recently curated article that either attempts to answer the question, or adds depth to the inquiry.

5G Nervous System = Real-Time QoE

Guest post by Scott Sumner, Accedian

Emergence of the instrumentation layer in real-time, intelligent networks.

5G networks will support a diverse array of applications, from 4k video streaming to safety-critical IoT, autonomous cars and factories, and hosted transactional applications that let us work from anywhere.

The competition for limited spectrum and network resources collides with increased complexity as networks layer-in virtualization to increase agility, manage network slices, and dynamically allocate capacity (both bandwidth and compute) where required.

The Cost of 5G and the Next New Shiny Thing

Guest post by Iain Gillott, iGR Research

We in the mobile love to discuss ‘the next big thing’ – we are never happy living in the present and always want the next new shiny thing.  Perhaps this is because of the way the industry developed in the mid-1980s, from humble analog networks (really, they were not that good!) to digital networks and then to 3G and beyond.  Of course, along the way we never agree on a single network technology (2G was covered by at least four standards) and so even as the latest-and-greatest technology was always been promoted.

Now that we have got to LTE (which most of the world agrees on for ‘4G’), it is time for the next shiny thing: 5G.  The problem with 5G at present is that if you talk to five people about 5G and what it is, and you will get at least seven answers! What stands out more than any new 5G technology, air interface or spectrum is the general level of confusion and lack of definition.

Building Customers through Skilling

Guest blog post written by Sanjeev Duggal, CEO & Executive Director, Centum Learning Ltd

Improved economic conditions have fueled unprecedented telecom growth in Africa. It is estimated that by 2016 the continent will have a billion mobile phones. According to a World Bank report, nearly 16% of adults and 31% of those with a formal bank account in Sub-Saharan Africa have reported using a mobile phone to pay bills or send / receive money in the last 12 months.

Africa’s status as being the second most mobile connected continent where about 15% of its billion inhabitants own a cell phone has ushered many African nations into a digital economy and changed lives of people for the better. The telecom revolution has touched people through better access to education and entertainment, helped in disaster management and better agricultural yields and brought people together through social media.

Guest post – Promoting economies of scale in device testing

Guest post by the Global Certification Forum

The extension of mobile phone and broadband services across the globe has been built on our industry’s adoption of global standards.  Verifying that new devices conform to those standards is of great importance to manufacturers and operator alike. As devices become more complex with the overlaying of new mobile technologies on legacy standards, there could be a danger that pre-launch testing becomes so cumbersome that the full economies of scale from standards can’t be realised.

That’s where GCF Certification comes into play.  Developed and maintained through the collaboration of experts from manufacturers, operators and the test industry, GCF Certification has become the global baseline for assessing interoperability between mobile devices and operators’ networks and services. Certification brings economies of scale to device testing.

The roll-out of any new generation of mobile network technology is never as simple as flicking a switch. Much of the current discussion around 5G is about its definition. But 5G won’t truly happen until it can actually happen in the network. Like all grand designs, obstacles need to be overcome in order to achieve that goal.

Like other industry commentators, my fundamental viewpoint is that 5G will be a “network of networks.” Network densification involving macro sites, in-building wireless, metro cells and small cells will continue on the way to 5G. This densification adds more complexity to wireless networks and demands ever more sophisticated infrastructure solutions. Managing these multiple network layers efficiently is becoming ever more important to deliver 5G speeds and throughput.

Beyond data offload: Gemalto’s advanced Wi-Fi services put new revenue streams within easy reach

Guest post by Jean-François Gros, Marketing & Business Development Director, Gemalto

Guest post by Jean-François Gros, Marketing & Business Development Director, Gemalto

Among consumers, Wi-Fi is perhaps most commonly associated with the simple pleasures of a few minutes free surfing on the train or alongside a coffee. For mobile network operators, however, the stakes are rather higher. With pressure to build capacity and coverage combining with a fiercely competitive marketplace, the inexorable spread of Wi-Fi offers a compelling route to enhanced customer experience, differentiation, and new revenue streams.

Whilst much attention has focussed on the 4G roll-out, Wi-Fi’s contribution to the connectivity eco-system has largely flown under the radar. But the figures speak for themselves.  It is widely reported that, by 2018, there will be one hotspot for every 20 people on the planet; by 2017, seven billion devices will be Wi-Fi enabled1.

5 Ways IPX is making LTE a global success

This guest blog was written by Jay Jayasimha, Chief Technology Innovation Officer, Cataleya 

Jay Jaysimha

LTE needs IPX to be a truly global success. When domestic LTE deployments are supported by global IPX-enabled networks, it changes what is possible in the mobile market. Today, we’ve seen the development of LTE networks on a local level but for 4G services to mature and realise their full potential LTE needs to be supported with robust, reliable and intelligent IPX-enabled networks.

There will be 450 commercial LTE networks deployed by the end of 2015, according to The Global Mobile Suppliers Association (GSA). Close to 50% of subscribers in Q4 2014 were in Asia-Pacific with North America and Europe trailing close behind.

Exclusive interview – Steven K. Berry, President and CEO of CCA (Competitve Carriers Association)

Steven K Berry, President & CEO of CCA

Steven K Berry, President & CEO of CCA

Ahead of the 8th Annual LTE North America event in Dallas, TX this November 18th & 19th, we had the opportunity to interview Steven K. Berry, President & CEO of the Competitive Carriers Association (CCA).

In the interview Steven shares his thoughts on the key challenges being faced by competitive carriers throughout the U.S., the industry’s concerns looking forward to 2015, and the path towards a competitive landscape for all carriers.

Q. What are the key challenges faced by North American carriers today in the roll-out and upgrade of LTE networks?

A. Competitive carriers must have access to critical inputs including access to spectrum, access to the latest, most-advanced handsets, and reasonable roaming agreements to continue to improve and build out their networks.  Carriers in the most rural and hard to serve areas also need certainty regarding sufficient Universal Service Fund (USF) support.  Competitive Carriers Association (CCA) works each and every day to ensure our members, nearly every wireless carrier in the U.S. outside of AT&T and Verizon, have the opportunity to grow and thrive, and to do so, they must have access to these inputs to find a pathway toward the next generation of networks.  The wireless industry is, unfortunately, plagued by continued consolidation – a significant challenge for smaller carriers trying to compete with the two largest national carriers.  We have been working closely with the Federal Communications Commission (FCC or Commission), Congress and the Administration to ensure policies are in place that will allow our members to enhance their networks and serve their customers the best way possible.  Tim Donovan, VP of Legislative Affairs for CCA, is speaking at the LTE North America event and will address some of the critical policy issues for CCA members and how decisions made in Congress and at the FCC affect not only the carriers, but consumers and the economy as well.

NFV: What’s Good? Price/Performance for Starters

Guest post by 6Wind

TL;DR: NFV Promises To Alter The Value Proposition For Network Operators Of All Sizes

As we prepare for SDN Asia 2015 in Singapore this October, we look forward to discussing how executive telecom decision makers want to capitalize on the APAC market’s propensity for rapid technology adoption by providing an abundance of services at the lowest costs. NFV enables rapid service creation while lowering costs, but it is necessary to not sacrifice performance in the process.

Performance continues to drive the NFV discussion because without proper oversight, virtual machines and cloud infrastructure can be real headaches by demanding increasing requirements of hardware to accommodate an increasing software footprint. To achieve an abundance of services at the lowest costs, enabling performance in the initial design architecture will help further drive the costs down. There are two major areas of performance bottlenecks that organizations should evaluate to enable the full promise of NFV.

Haitham Mashal, Senior Director- CS Core, Du

Prior to the LTE Voice Summit (London, September 28th-30th), we interviewed Du’s senior core network Director Haitham Mashal about his views on the development of VoLTE, service planning and future opportunities. Here is what he had to say, ahead of his participation at this year’s summit.

Q. As we see the commercial launch, is there any clearer idea of whether VoLTE will truly live up to its promise?

A. No doubt VoLTE would even exceed its promise for both customers and Operators. Operators would have the chance to transform their networks into full fledge IP network and get the benefit of reducing both CAPEX and Opex. Operators would also be capable to offer better Voice quality with enriched services on top of the voice that can compete with OTT voice services.

Customers would enjoy the enriched crystal clear HD voice and shorter time setup. This would definitely enhance the customer experience and satisfy the customer demands to enjoy different services simultaneously even during call establishment.

NFV RoI: The Current Business Drivers for Mobile Virtualisation

Written by Paul Jesemann, Cisco Solution Consultant, Mobility Architecture, APJ

Written by Paul Jesemann, Cisco Solution Consultant, Mobility Architecture, APJ

If someone were to define a safe bet, it would be on the number of blogs about NFV, its drivers and benefits out there, by far exceeding the actual number of Virtual Network Functions deployed. So please let me try a different perspective.

We have been talking about NFV for more than two years now. There is no shortage of studies and surveys on its drivers and potential, but what can be said about reality? A reality I would like to delineate as follows… To CTOs and CIOs, NFV (and SDN) is something to drool or to brag about: “We will adopt it” or “We have great results from adopting it”, and an occasional “We have been doing it in the lab for ages, so…?” . But as Geoffrey Moore tells us the “Techies” and “Visionaries” don’t make a technology, until it can be recognised by the majority.

Here comes the important part for “crossing the chasm”: How about successfully addressing the key CFO’s question, “Show me the money”?

What makes me feel great about NFV now becoming a reality, is the fact that there are numerous examples globally, where CFO’s have “found the money”, resulting in commercial NFV deployments. Take AT&T Connected Cars or Telefonica’s “LTE in a Box” as an example for revenue increase business case – not just an approved one, but a proven one! How about a cost reduction one like XL Axiata are confidently aiming for . And if you think increased agility is an esoteric one, look at what Aspider or NAKA Mobile can create with NFV, agility does get signed off, so I assume it also pays off!

In the whole discussion, using Geoffrey A. Moore’ “Crossing the Chasm” reference, is it important where to place the named service providers? Maybe as pragmatics – but what is far more important than a classification is the fact that they are doing it – congratulations!

I do acknowledge that there are still many challenges ahead to reach mainstream Mobile NFV deployments– orchestration or  interoperability being one of them (thank you Light Reading and EANTC!), and I am as pleased as I am sure to believe they would be adequately addressed. But that’s maybe another blog some time soon.

Bringing Accurate Synchronization to Small Cell Backhaul

This guest post was written by Alon Geva, Timing & Synchronization Expert, CTO Office at RAD

Delivering sub-microsecond time accuracy to cellular base stations is one of the major challenges facing cellular providers as they deploy their new LTE networks, creating unique challenges in the backhaul segment. This is exacerbated by LTE-A’s stringent synchronization requirements and, eventually, by 5G, now on the horizon.

Before the debut of 4G, the standard way to deliver a clock reference was to install Global Navigation Satellite System (GNSS) access at every cell site. A GNSS receiver is usually referred to as a Primary Reference Time Clock (PRTC).

The limitations of GNSS

This approach, however, is impractical in the 4G environment, since its network architecture is different. The most prominent change is that 4G accommodates large numbers of small cells to deliver higher capacities and data speeds. Stationing a GNSS antenna at every 4G cell site will be problematic due to cost. Apart from the unprecedented volume of antennas that would have to be bought, installed and maintained, the rapidly falling price of small cells will accelerate their deployment only further. Beyond all this, of course, is that every antenna requires an unobstructed sky view, a major problem for small cells, which, in many cases, are installed indoors, on building walls and closed spaces such as shopping malls, basements and traffic tunnels.

But that’s just the beginning.

The velocity in how the world creates value has hastened considerably. We spent millennia as an agrarian economy, then came the industrial age that refines these commodities into manufactured goods. We have since evolved into the service economy and most will agree that we are now onto the experiential economy.
To appreciate what that means to us in the telecommunications business, perhaps we can take a moment to follow the journey of the humble coffee beans.

Landscaping QoE in a new mobile world

This guest post was written by John Twohig, Solutions Architect at Eirteic

John is a Solutions Architect at Eirteic

John is a Solutions Architect at Eirteic

Today, Mobile Service Providers find themselves struggling to cope with the increasing demand for capacity whilst maintaining a high level of customer experience. Trying to find the most flexible and cost-effective infrastructure to support next generation services whilst also attempting to reduce customer churn by providing adequate customer level Quality of Experience (QoE) & Quality of Service (QoS) can be difficult to achieve. Essentially, Service Providers are caught between a rock and a hard place.

Subscriber level QoE is a subjective matter that is a balancing act; there are a number of factors which need to be considered:

  • Localised low signal quality
  • Numbers of connections using the network in a particular area
  • The performance of a particular mobile handset
  • Download bitrate
  • Resolution and encoding of video content
  • Responsiveness of mobile or web based applications
  • User service plans

Exclusive interview with Kobus Smit, Head of Voice and Messaging, Deutsche Telekom

Ahead of the 3rd annual LTE Voice Summit 2015, I interviewed Kobus Smit, Head of Voice and Messaging at Deutsche Telekom who gave us an insight on services VoLTE will offer + customer benefits it will bring- here is what Kobus say’s  in this exclusive interview

Ahead of the 3rd annual LTE Voice Summit 2015, I interviewed Kobus Smit, Head of Voice and Messaging at Deutsche Telekom who gave us an insight on services VoLTE will offer + customer benefits it will bring

Q. As we see the commercial launch, is there any clearer idea of whether VoLTE will truly live up to its promise?

A. VoLTE offers some clear customer benefits – especially around HD voice quality and faster call set-up times, which we believe customers will notice and appreciate. There are also further advantages, like high speed browsing during a call, but the usecases are still pretty limited. The largest benefit of VoLTE, however, is arguably for the Operator and not so much for the customer as it facilitates the necessary transfer of voice to IP. We therefore belief that from a customer perspective “plain” VoLTE alone will not necessarily be a very convincing proposition.

Q. Can we expect to see new and innovative services built on top of plain audio VoLTE?

A. Yes indeed – and it is already being prepared. DT has developed an Enriched Calling proposition together with Sony, Vodafone and others, which we will be bringing to market soon. This enables customers to have a far richer calling experience by adding context and content before, during and after a call. The features include the setting of call importance, adding a subject, picture or location before the call; during a call, users can exchange, locations, draw on maps or pictures, share videos, images and files, and after the call customers have the possibility to leave a visual voicemail, a video or text message. All of this is delivered with very little incremental effort, by utilizing RCS functionality already available in the network and handsets to deliver a truly enhanced user experience.

Q. What is the future, beyond VoLTE? What are the next steps in network development?

A. We are deploying VoLTE on a local basis first and will then extend it to Roaming. We further plan to combine VoLTE with other voice services such as WiFi Calling and plan to establish Video Calling. With VoLTE as a basis for IP voice, it opens the possibility of further enhancement and service meshing in the IP domain.

Q. Network Function Virtualization for VoLTE- what does this to you and is the way forward for this service?

A. For us it is not about the virtualization of one single service, its more about the virtualization of the network infrastructure in order to be more efficient and offer better quality and service for our customers.

Q. What will be your key message at the LTE Voice Summit 2015?

A. Enriched Call builds an attractive proposition around VoLTE.

Carrier Challenges

The sheer number of Wi-Fi connected devices is growing at a phenomenal rate, and Wi-Fi is fast becoming the preferred method of connection – at least two thirds of consumers today prefer connecting over Wi-Fi as opposed to cellular, mostly due to cost and performance.

Mobile operators have been increasingly turning to Wi-Fi offloading as a cost-effective way to manage data capacity, and that trend continues. Many analysts are forecasting a steady annual increase in carrier hotspots to more than 7 million by the end of 2015. (Source: ABI Research)

However, data offload is just the tip of the iceberg. The real reason many carriers are out there securing hotspot locations and launching services is competition for new revenue opportunities, from both incumbents and “over-the-top” (OTT) players alike.
