OpenRAN enthusiasm spreads to Turkey

Mavenir has announced Turkcell as its latest customer, with the pair planning to deploy OpenRAN vRAN technologies in the telcos domestic market.

As part of the agreement, Mavenir’s Virtual RAN solution will be deployed on Turkcell Telco Cloud and it will be first workload that will be going live on Turkcell Edge Cloud. Mavenir claims this vRAN architecture and platform can support 4G as well as both the NSA and SA implementations of 5G NR.

“At Turkcell, we have reached more than 60% virtualization in our mobile core network. We already take great advantage of what virtualization has to offer and are willing to extend the benefits of virtualization coupled with OpenRAN for the next step in Turkcell’s Radio Access Network evolution,” said Gediz Sezgin, Turkcell CTO.

“With its broad experience and expertise in RAN technologies and Network Virtualization, Turkcell will make great contribution for innovation on open vRAN towards 5G era. We are excited to take on and lead this journey.”

Turkcell becomes the latest in a string of companies seeking to drive forward with the OpenRAN technologies, though it is not entirely clear how scaled the deployment will be. There are of course interesting promises being made by the OpenRAN community, though few telcos would be prepared to invest comprehensively during these embryonic stages of development.

To understand where OpenRAN might gain the most traction it would probably be best to look at the regions with the lowest ARPU. Turkey is an interesting market, as according to data from, the average price of GB on mobile tariffs is as low as $2.25. This is certainly not as low as some other markets, though it starts to get tricky to drive ROI when data tariffs are below global averages.

The promise of OpenRAN is to commoditise the hardware components of the radio access network, which will allow hardware and software to be decoupled. This should, in theory, reduce the cost of radio deployment and remove any vendor lock-in threats which may still persist. This is an attractive idea for companies who need to rebalance the expenditure/profitability equation.

For the moment it is difficult to see what the long-term position of OpenRAN in the vendor mix will actually be. It is not resilient enough a technology just yet for scaled deployments, though some have suggested enthusiasm for trials is a stick to beat traditional vendors down on price.

In the markets where ROI is disastrously difficult to realise, OpenRAN will certainly play a role in the future, as it will probably in rural regions. Though it does remain to be seen how much of a dent OpenRAN will put into the fortunes of the traditional RAN vendors.

TIP taps out its top achievements

The Facebook-founded Telecom Infra Project has offered an update on all the telecoms stuff it’s up to.

At the top of the list is its OpenRAN project, which promises to disrupt the industry by decoupling many of the component parts of radio access network gear, thus opening it up to greater competition. We’re told the rate of ORAN trials has significantly increased over the past year. On top of that another, related project focusing on disaggregated cell site gateways seems to be motoring along nicely too.

Rather ironically research into things like ORAN has become somewhat disaggregated itself, with other groups like the ORAN Alliance apparently working in parallel to the core TIP efforts, despite sharing most of the same members. Anyway, sensibly they have announced a ‘liaison agreement’, through which they promise not to hide stuff from each other in the area of interoperable 5G RAN solutions.

On top of that the GSMA has promised to muck in too and the OpenStack Foundation and the OpenAirInterface Software Alliance will explore collaboration areas on the newly formed Open Core Network Project Group. All this stuff is covered in a fairly comprehensive blog post by Attilio Zani, Executive Director at TIP​, which was clearly designed to coincide with MWC (RIP). The post includes the diagram below, which seeks to illustrate the scope of projects it’s involved in.

One of the major contributors to the ORAN effort, Mavenir, even had its own announcement designed to coincide with the TIP update. Mavenir has collaborated with Facebook Connectivity, MTI, Deutsche Telekom and others, to launch the Evenstar Remote Radio Head family. It’s intended to accelerate the adoption of ORAN tech by building general-purpose RAN reference designs for 4G and 5G networks.

“The Evenstar program is supported by a group of like-minded organizations that share a common goal of accelerating the adoption of Open RAN,” said Mikael Rylander, SVP and GM of the Radio Access Business Unit at Mavenir. “Through this collaboration, we hope to release RRHs with the latest features and competitive pricing. The Evenstar RRH and the program itself will help level the competition in both technical specification and price.”

“To benefit from next generation, open, disaggregated RAN solutions that can be implemented in various deployment scenarios for 4G and 5G networks, it is important for Deutsche Telekom to work with innovative partners driving ORAN compliant technology,” said Abdurazak Mudesir, SVP Technology Architecture & Innovation at Deutsche Telekom. “This collaboration between the ORAN and TIP communities is an important contribution to grow that ecosystem and accelerate the commercialization of Open RAN technology.”

While the development of novel technologies is usually a fragmented process in its initial stages, TIP and ORAN have been around for a few years now, so this increased collaboration seems overdue. While we still seem a long way from ORAN taking the place of any of the big RAN vendors in commercial networks, the rapid progress it seems to be making will surely be a cause of nervousness.

Mavenir looks to cash in on US xenophobia

At times, US anti-China rhetoric flirts with the line between protectionist and xenophobic, but that won’t bother the likes of Mavenir as it touts its All-American credentials.

It what appears to be a relatively unprompted submission, Mavenir lawyers have filed documents with the Federal Communications Commission (FCC) stating the firm is as patriotically-US as apple pie, watery lager, high-powered rifles and gas-guzzling jeeps.

The objective here is quite clear; the US political administration does not like China, is prepared to spend big to supercharge an alternative telco vendor to the likes of Huawei or ZTE, and Mavenir wants to get rich as the establishment attempts to drown the success of China’s technology industry under the patronising veil of national security.

It is opportunism at its finest.

“Mavenir noted that it is the industry’s only US-owned, US-headquartered, end-to-end network software provider delivering OpenRAN and virtualized networks,” the filing states.

There are of course other companies who could be deemed American, though it appears they have their own faults. Parallel Wireless, for example, is headquartered in New England, is funded by Californian moneymen, but some of its founders are Indian. It almost ticked all the boxes!

Although it is an unusual strategy from Mavenir, it might work.

US politicians might be losing the political battle to extend its anti-China rhetoric throughout the world but presenting a genuine alternative might be one way to aid this propaganda campaign. An alternative which is also driving forward the attractive OpenRAN technology to add a cherry on top.

While it might still be a technology in its infancy, OpenRAN is capturing the hearts and minds of those who want to force through disruption in the RAN ecosystem. The Nokia/Ericsson/Huawei cartel does not present a significant amount of competition, which OpenRAN could help with, while it could also make the economics of 5G network deployment more attractive.

There are a few initiatives which are progressing around the world. Rakuten is deploying a fully virtualised network with the OpenRAN community at the heart. Admittedly it doesn’t have to worry about legacy technologies muddying the waters, but Vodafone, MTN, Telefonica and Etisalat are attempting to blend OpenRAN into a more traditional network work environment, with legacy complications and all.

Earlier this month, the Democrat Senator for Virginia Mark Warner introduced a new bill to Congress. The Utilizing Strategic Allied (USA) Telecommunications Act will aim to provide $1 billion to create Western-based alternatives to Chinese equipment providers Huawei and ZTE. This is the prize the Mavenir gold-diggers are chasing.

And to sweeten the deal, Mavenir has also suggested it is able to help the poor rural providers dig out the dangerous technology from naughty Huawei and ZTE. We suspect it will all be done for a patriotically attractive price, or at least attractive to the Mavenir swashbucklers.

This is what some might call underhanded PR, a tactic which is more at home on ‘The Thick of It’ than the telecommunications slugfest. But it is an excellent of opportunism, which will probably be successful for the All-American vendor.

What are Boris Johnson’s alternatives to Huawei? periodically invites expert third parties to share their views on the industry’s most pressing issues. In this piece John Baker, SVP of Business Development at Mavenir argues that OpenRAN must signal the start of a new cycle for infrastructure vendor market.

For many years now, the telco infrastructure market has been dominated by just three vendors – Huawei, Nokia and Ericsson.  Other firms have fallen by the wayside, unable to compete on price or move fast enough to keep up with changes in technology.

Of course, the mobile ecosystem has always encouraged innovative players to develop new solutions and there are plenty of companies supplying the operator community with specialist network products and services. Having said that, there is no doubt that the operator choices for its end to end Network infrastructure vendor have reduced over the last 10 years.

Now one of those three Network vendors, Huawei, is facing a geopolitical and commercial storm itself. The US government has turned against it for its 5G infrastructure and is putting pressure on other NATO countries to do the same – causing Britain’s PM Boris Johnson to cry out ‘but what are the alternatives?’

Whatever the truth of the matter or the motive for raising it, US fears about hidden spyware or an over-reliance on the technology from a vendor thought to be controlled by a ‘competing nation’ is causing a major market stir and threatening to exclude Huawei from operator tender lists across the USA and Europe.

Commercially, this can be portrayed as good news for Nokia and Ericsson, but it is not quite that straightforward.  Firstly, a reduction to just two vendor choices cannot be good for the market. Secondly, all this is happening at the same time as the technology is rapidly evolving, creating new ways of building networks and delivering services.

Operators concerned about their dwindling source of options for network  infrastructure – and already frustrated by the feeling of being trapped into ‘vendor lock-in’ of hardware-centric solutions – are therefore increasingly attracted to the commercial and technical opportunities of virtualization; and especially to the new breed of vendors emerging with software-centric  solutions.

What’s more there’s a general feeling that the traditional vendors, after naturally taking a protectionist stance to the hardware model that underpins their businesses, are no longer at the leading edge of the technology when it comes to the software-led world of virtualized networks. Ericsson, for example, has so far shied away from embracing OpenRAN – an initiative that allows networks to be built using off-the-shelf servers rather than proprietary boxes.

The OpenRAN initiative is at the heart of the Facebook-led Telecom Infrastructure Project (TIP) looking to bridge the digital divide by lowering the cost of mobile network deployment. It’s also been welcomed by Vodafone, as evidenced by the RFP it has issued looking to convert its entire European footprint to an OpenRAN model.

Late last year, analyst Stephane Teral at IHS Markits cited my own company, Mavenir, as being best placed to become the new third choice vendor in the market.  But this revolution in supply is not just about adding one or two new vendors to the supply chain to answer Boris Johnson’s plea.

It’s about the creation of a truly new infrastructure market model.  One where open interfaces, software-led, cloud-based network architectures with end-to-end automation become the new normal.  It’s a wind of change bringing a new cycle in the infrastructure vendor market – giving operators more choice, lower costs, more service flexibility, and a faster return on network investment.

O2 joins the OpenRAN movement

O2 is the latest telco to join the increasingly popular OpenRAN cause, suggesting the technology could better serve customers in the hard to reach and heavily-populated areas.

Working with Mavenir, DenseAir and WaveMobile, O2 will aim to deploy the technology in dense urban environments, as well as the smaller, isolated rural communities. Like every telco, O2 is attempted to fine-tune the economics of network deployment as the realities of significant 5G investments start to rear their head.

“Connectivity is a lifeline for consumers and businesses alike and we’re committed to delivering the best possible network experience for our customers,” said O2 CTO, Brendan O’Reilly.

“O-RAN represents a really exciting opportunity to deliver better coverage, in more places, more of the time. By opening up our radio access network to smaller vendors, and as we look towards wider adoption of 5G, O-RAN will be part of the solution to bring the latest connectivity to more people around the country.”

The Mavenir segment of the project will focus on high-density environments in London. The objective will be to provide enhanced mobile connectivity and better customer experience in high-traffic areas such as stadiums and shopping centres.

“Densification of coverage in cities is a challenge but OpenRAN is ready to take it forward and Mavenir is proud to work with O2,” said Stefano Cantarelli, CMO of Mavenir.

O2 has said the WaveMobile OpenRAN technology is currently active on several sites across the UK including Woldingham in Surrey, and the solution could be used to provide connectivity services in ‘not spots’ in the future.

OpenRAN is increasingly looking like an attractive idea not only because of the technological benefits, but also the commercial. Firstly, opening-up the network to new suppliers will encourage innovation in new areas, and secondly, it puts pressure on current suppliers to negotiate more favourable terms with telcos.

Some might call it cynical, but there have been suggestions that Vodafone’s aggressive move towards OpenRAN is a ploy to gain the upper-hand during negotiations with the likes of Huawei, Ericsson and Nokia. These traditional suppliers will of course want to hold onto contracts, and prevent money heading towards the likes of Mavenir, Parallel Wireless and Altiostar. Success breeds success after all.

The more noise makes about OpenRAN as a realistic alternative to the status quo, the more nervous traditional RAN vendors will be. But this is not to say OpenRAN will not take its place in future networks on its own technological merit, it is just a factor which is worth bearing in mind.

Although O2 should certainly be categorised as an early adopter of the technology, there are other existing projects worth noting.

Rakuten will soon become the fourth mobile player in the Japanese market, with its network deployment driven by OpenRAN. Few have the luxury of a greenfield approach like this, but that has not stopped Vodafone deploying OpenRAN in the UK, DRC, Mozambique, South Africa or Turkey. Similarly, Etisalat in the UAE recently announced it was working with NEC, Cisco and Altiostar to deploy the open technology in its own networks.

And over in the US, various Senators and FCC Chairman Ajit Pai has been plugging the technology as an alternative for Huawei. Senator Mark Warner recently tabled a bill in Congress which would direct as much as $1 billion toward the OpenRAN community. It will not replace the traditional RAN ecosystem any time soon, but OpenRAN is here and here to stay.

O2 expects the commercial deployment of OpenRAN to accelerate over the next 18-24 months. This might be bad news for the traditional RAN vendors, but with Mobile World Congress kicking off in just over a month, there might be a few more announcements in the pipeline.

Vodafone searches for supply chain rejig through OpenRAN

Vodafone has announced it will introduce OpenRAN technology in various parts of its UK network, as well as the Democratic Republic of Congo (DRC) and Mozambique.

In what appears to be an effort to break down barriers to work with new vendors, Vodafone will seek to empower the ecosystem through the introduction of commoditised hardware. This is the first trial of the technology in a ‘developed’ market, leaning on trials which have taken place in Turkey and South Africa.

“We are pleased with trials of OpenRAN and are ready to fast track it into Europe as we seek to actively expand our vendor ecosystem,” said Vodafone CEO Nick Read.

“OpenRAN improves the network economics enabling us to reach more people in rural communities and that supports our goal to build digital societies in which no-one is left behind.”

Launched through the Telecom Infra Project (TIP), the OpenRAN initiative aims to build 2G, 3G and 4G RAN solutions based on a general-purpose vendor-neutral hardware and software-defined technology. With vendor-neutral hardware hitting the networks, the aim is to reduce reliance on a small number of vendors, de-couple the hardware and software components of the network more stringently and reduce the vast expenditure made on network infrastructure.

The UK trial will focus on rural locations, perhaps to reduce the exposure of failure. These are also the cell sites which will cost the most and offer the smallest profits. There is a lot to gain here, while the consequence of failure will be limited.

“Encouraging the emergence of new suppliers would give operators greater choice in a far healthier ecosystem,” said Kester Mann of CCS Insight. “Disrupting the status quo could, in particular, make the economics of network deployment stack up in rural areas or hard-to-reach locations, for which roll-out may not currently be viable or cost effective.

“Improving network economics and better monetising infrastructure assets is an important focus of Vodafone CEO Nick Read as the company seeks to achieve ambitious cost-saving targets.”

Like many of the worlds’ telcos, Vodafone is slowing stumbling towards a tricky situation with its supply chain, though many of the issues are outside the control of the company. With Huawei under increasing pressure, the future does look glum for a segment of the ecosystem which is already under-populated.

However, the telcos are not completely blameless in this situation. Investments have been concentrated with the three major vendors in this space (Huawei, Ericsson and Nokia). Through prioritising these companies as primary vendors, challengers have not been given the opportunity to scale and compete. Another complaint levelled at the telcos has been a comprehensive and convoluted procurement process, which has inhibited the ability of smaller players to compete against the status quo.

When the industry is running smoothly, few would have complained with the concentration of investment to a small number of vendors, but there are wrenches being thrown into the works all over the place.

With Huawei potentially facing bans in numerous countries and its supply chain being compromised thanks to the entry onto the US Entity List, a major vendor is under threat. Although Huawei has confirmed it is producing products free of US components, the performance of this equipment is unknown for the moment. Worst-case scenario, the vendor community could become a lot smaller.

Vodafone is one company which does look to be exposed to the Huawei conundrum. UK CTO Scott Petty has said banning Huawei would set the company back two years in its quest for 5G, costing millions as the company would be forced to strip the vendors equipment out of its network. Huawei equipment currently accounts for 32% of the 18,000 base stations around the country, though it has plans to strip Nokia equipment out, with Ericsson taking the rest.

Only working with two suppliers is a precarious situation, though this is compounded when you look at the difficulties Huawei is facing. The introduction of OpenRAN might be considered a bold move, but it is starting to look very necessary to enable access to more vendors.

The trials in the UK, DRC and Mozambique will focus on mobile calls and data services across 2G, 3G and 4G, with 5G possible over OpenRAN in the future. OpenRAN could be debuted elsewhere across Europe dependent on the success of the trials in the UK.

The team have currently identified 100+ rural locations to trial the technology, though this could be expanded in the future. Vodafone has said OpenRAN could reduce network hardware costs by up to a third, but this is dependent on how the technology and supplier ecosystem develops over time. Mavenir, Parallell Wireless and Lime Microsystems are three new suppliers enabled by the trials, though there are a huge number of start-ups who are connected to TIP.

Although this is a small trial for the moment, it is certainly one worth keeping an eye on. Vodafone is in a slightly tricky position when it comes to its supply chain, though should OpenRAN prove to be successful, numerous options could be opened-up. It is a low risk gamble, though the gains of a new supply chain certainly outweigh the consequence of failure.

Mavenir places fortunes in hands of big boys and RCS

Mavenir is a business which has been growing steadily over the last few years, capitalizing on the virtualization buzz, though future prospects could ultimately be out of their control.

One aspect of the business model for Mavenir is simple. It is somewhat reliant on the process of decoupling hardware from software, the emergence of standardised NFVi, which in turn will allow operators to reduce spending on hardware, placing more emphasis on software, which is the dream situation when rolling out the 5G world. Mavenir does of course have some pretty handy technology outside this grand plan, but this seems to be the general thesis.

This trend of decoupling hardware from software is already underway, though admittedly progress has been lethargic to date due to resistance from today’s heavyweight vendors and some operators clinging to the strategies of yesteryear, but staggered steps forward are being made. This is where Mavenir can enter the fray with the knockout punch; because its business model is not associated with hardware, it can offer software products and services cheaper.

The overarching theory is sound. Companies like Huawei and Ericsson, despite becoming software players in their own right, will have to protect total revenues; the transition from an integrated hardware/software solution to purely software will drop revenues, therefore in the first instance prices in the pure-play software business will be inflated. These are companies which will not want to shock investors with a plummet in revenues, therefore the transition into the virtualized world with be ‘managed’. With the traditional heavyweights overcharging, Mavenir can swoop in and undercut because there are no legacy hardware business revenues to worry about.

This all sounds like a very effective business model, but a lot of it is dependent on factors which are outside the control of the company itself. As it stands, Mavenir is profitable, with revenues of roughly $500 million and plans to grow this number to more than $1 billion in four years, but this all depends on virtualization trends picking up pace, operators embracing the new dynamics of the digital economy, 5G deployments to be as optimistic as currently being preached, and of course the assumption they can undercut the bigger boys on price.

But this is only one part of the Mavenir story, the other is focused on RCS, and looks incredibly promising. To date, RCS has been somewhat of a dirty word for the operators, with the webscale player plundering the bounties. But the tide is turning. Recognising the potential for RCS when delivering new services in messaging and multi-media content, it is embraced by operators in North America, with trends slowly beginning to sail across the Atlantic to Europe.

In the RCS world, Mavenir has been one of the first to get to the party. The team has already developed cloud-based applications, allowing easier integration for the operators, but more importantly, these applications aren’t just focused on the consumer services. This is where the webscale players have been reaping the benefits, but with an eye on the enterprise services market, Mavenir has the potential to make solid progress.

Another very important factor is the procurement process. The team already count 240 companies around the world as customers, and many of these customers are fickle beasts. They don’t like the unknown and fear change, the fact Mavenir is already a known entity is a positive. But known under what name…

This has been the plague of the business for the last few years. It was known as one name, then another brand, before adopting a new logo. Consistency has not be a major play, which will certainly make some nervous. A big question is whether Mavenir has permanently solved its identity crisis.

The theory about being able to undercut competitors is believable, but until competitors start talking about pricing models, we’ll never actually know. The assumption here is competitors will be defensive of hardware revenues, not aggressive on the software side. However, trends in the VoLTE world, where Mavenir is arguably knocking the likes of Nokia and Ericsson off the pedestal, and RCS are looking promising for the business.

A large component of Mavenir’ success seems to be heavily reliant on the deviousness of today’s mega-vendors and whether they will abuse relationships with customers, as well as adoption trends with are largely uncontrollable. A lot of future success seems to be dependent on moving cogs functioning smoothly and in a timely manner, but the team is confident… some might even say cocky.

vMBC delivers vital internet traffic offload at the network edge periodically invites third parties to share their views on the industry’s most pressing issues. In this piece John Baker, SVP, Business Development at Mavenir looks at the benefits of the Virtualized Media Breakout Controller.

Operators are facing a dilemma – How to remain profitable while cost-effectively meeting rapidly escalating network capacity demands. Nearly 80 percent of user data that transits an operator’s network is encrypted video that only benefits OTTs. It is in each operator’s best interest to architect the network to off-load this traffic at the nearest point possible.

The Virtualized Media Breakout Controller (vMBC) is the answer ­– allowing user traffic to offload to the cloud as soon as physically possible. “Approximately 40 percent of video content could be cached at the edge,” according to Iain Gillott, President and founder of iGR. “The trick is to be able to benefit from the feature and operational cost benefits without having to upgrade to 5G architectures.” vMBC makes this possible with an innovative, new white box platform designed to be positioned for cost-effective function at the edge of the network.

Defer Bandwidth Increases for Two years

With bandwidth consumption growing exponentially each year, the vMBC breaks out local traffic and directs it from the network edge, instead of moving it back through a typically centralized packet core. This offloading conserves transport and centralized packet core network assets on both control and user planes.

What does this mean for operators?  In one feasibility scenario, iGR estimates that if operators can offload 32 percent of the data from a network site (using a solution such as the vMBC), then they can defer spending on increased bandwidth for more than 25 months. On top of offloading traffic, the vMBC can be combined with additional virtual network functions (VNFs) that provide video optimization and caching as well as virtualized base band Units (vBBUs) for Cloud RAN. This opens the door to using previously excluded fronthaul solutions and processing of the radio interface on COTS processors, with each incremental function significantly and positively impacting Total Cost of Ownership (TCO).

Deploy Anywhere, Even Crowded Cell Sites

A local breakout solution offers the ability to host virtual routing, firewall, and user plane data offload in a single white box routing platform, deployable anywhere at the network edge including cell sites, near-edge data centers, local data centers and enterprise locations. With most cell sites being too crowded to add additional network equipment, the vMBC, along with other VNFs, can be loaded on a compute platform that can directly replace a traditional cell site router, ensuring the integrity of the existing network and seamless integration into next generation MANO operational systems.

Leading the Way to MEC and IoT

vMBC is a key part of MEC (Multi-Access Edge Computing) and IoT initiatives, improving next-generation core network services and providing a path toward 5G and edge computing. The ability to scale network functionality using virtual elements and COTS HW platforms allows network functionality to be deployed at any location.

vMBC is also optimized by design and architecture to support low latency use cases by enabling small form factor user plane deployment at the network edge. This greatly reduces network latency by allowing applications to be located close to where they are deployed, automatically replicating and synchronizing databases across multiple sites, providing complete failover capability. The solution is inherently fault tolerant and can scale without limits.

It’s all happening at the edge.
