Kerstin Günther is SVP Technology Europe for Deutsche Telekom. To hear her deliver more insights, come to the LTE World Summit, which is taking place on the 23 – 25 June 2014, at the RAI, Amsterdam. Hear her take part in a panel discussion with other leading CTOs discussing network innovations such as NFV and 5G.

What sort of changes have you seen on the network in terms of usage since you launched LTE?

When LTE networks were initially launched, the main target was to provide higher data throughput compared to HSPA+. At that point, initial bit rates were 75Mbps on the downlink with 10MHz channel spacing. Gradually, LTE networks have been upgraded to LTE+ providing 150Mbps downlink bit-rates, while last year we have seen the first introduction of carrier aggregation technologies with maximum downlink bitrates around 300Mbps and this year DTAG Group demonstrated in a live environment the introduction of 600Mbps downlink over-the-air achieving 580Mbps downlink bit-rate. Of course, the relevant terminal evolution is essential for the end-user to take advantage of this enhanced throughput.

What are the next steps you are focusing on in terms of network development and what impact will these steps have on your customers?

MWC Day Two – Innovations on Show

Cloudy with a Chance of Cost Savings

The second day of MWC proved to be another full-on day of hall walking and meetings, and innovation was on show aplenty.

That’s certainly true of Israeli VAS company CallUp. This small operation has just 25 employees but sells its products to operators all around the world, from LATAM to India. Its CEO Aron Roth explained to me how its CanVAS product can bring the value back for operators into services such as SMS and voicemail, which for those that are focussing on LTE are products that no longer really revenue generators,  but still have to be offered. The answer is the cloud. CanVAS offers these things via a cloud-based system, thus stripping out the high OPEX costs that carriers would otherwise face for these low revenue generating services. Interestingly Callup itself hosts these offerings on AWS – Amazon’s cloud services. So it’s a cloud service, built on top of a cloud service, which is kinda cool.

Hadi Hariyanto, senior researcher for Telkom, Indonesia is taking part in a panel discussion on integrating carrier Wi-Fi into telco networks on Day Two of the LTE Asia conference, taking place on the 18th-19th September 2013 at the Suntec, Singapore. Ahead of the show we find out more about the complex spectrum issues that are holding back the deployment of LTE in Indonesia.

A year ago you had completed LTE trials in Indonesia. How has your LTE network progressed since then?

We are monitoring the progress of the LTE ecosystem including device maturity, VoLTE, and new business opportunities. Since it is most likely that we will be using re-farmed spectrum, we have conducted an intensive study of heterogeneous networks. This technology will enable us to anticipate the possible challenges and opportunities of delivering seamless mobility between 3G, LTE and Wi-Fi networks.  We also actively contribute to a European ICT Project, related to LTE small cells and mobile cloud computing, which is called Tropic.  We believe mobile cloud computing will be a great source of new revenues on top of the LTE network.


Five big ideas for the modern carrier

As you head to the LTE World Summit, there are several big ideas floating around that could absolutely change the telecom business for network operators, perhaps making them more nimble competitors than they’ve been before. Here are five big ideas for today’s network operators that I hope to hear more about in the weeks ahead:

1) Proprietary hardware is becoming a hard sell. The world’s largest network operators have spoken loudly and clearly about their desire to embrace network functions virtualization (NFV). They want their network equipment procurement processes to change in favor of industry standard servers, Ethernet switches and IT systems running software apps from independent developers.

It remains to be seen if the incumbent equipment vendors will ultimately allow this — they seem to be the gatekeepers to carrier innovation — but it does signal that NFV is not a fad. It’s a big deal and establishing credibility in this space is critical for network equipment providers of all sizes.

2) If a vendor says, “Don’t do it,” they really mean, “We can’t do it.” The incumbent network equipment vendors have registered a few complaints about all that could go wrong by virtualising network functions. But the whining won’t stop what seems to be an inevitable march towards openly-programmable networks. Operators; if your vendors do more than the usual amount of whining, you should start worrying.

3) Over-the-top is normal. We don’t live in a “five nines” world. Anyone who has made a call on their cellphone, ever, understands that. We used to rely on “enterprise” apps and services to do our work. Now we use our Google Drive for documents, our S3 for data back-up, the DropBox app for file sharing and Netflix for entertainment. These aren’t telco-grade services — they’re better. The carrier response to all the over-the-top services should have happened years ago. Perhaps it will come someday, but that day won’t come until carriers are convinced they can redesign their networks to behave as flexibly and cost-effectively as the Web-scale companies that are currently making life easier and more productive for consumers and businesses everywhere.

4) IMS doesn’t have to be a roadblock to delivering VoLTE. The use of open source software inside of telcos is increasing and many telcos have expressed interest in Project Clearwater, an open source, cloud-enabled version of the core signaling functions of IMS. As operators are looking at the most cost effective route to offering voice over LTE (VoLTE), they should consider alternative routes that help them deliver telco-like services at using Web-scale economics. I’m looking forward to the panel on Wed. June 26 (“Bringing an Effective Voice Service to the Customer: Evaluating the Options”) where many of these issues will be discussed.

5) Google is not your enemy. Neither is Amazon or any of the other Web-scale companies that are providing services that used to be the exclusive domain of telcos. These Internet innovators have driven down the cost of cloud computing, contributed tons of code to open source projects and they test new network-based services on a willing public almost daily. Telcos can partner with, learn from and use the resources these innovators have made available to offer new services or, even better, allow new services to be created on their behalf. All they have to do is get over the perception that anyone using their networks for profit is somehow a problem to be addressed, rather than an opportunity to be harnessed.

Service quality assurance manager, VIPnet, Croatia: “Cloud is a major opportunity for operators to avoid simply becoming bit-pipes.”

Hrvoje Jerkovic, service quality assurance manager, VIPnet, Croatia, is speaking on Day One of the LTE World Summit, taking place on the 24th-26th June 2013, at the Amsterdam RAI, Netherlands. Ahead of the show we find out more about his views on various topics, including cloud, RCS, and VoLTE.

What major developments have there been with regards to the LTE industry in your region this past year?

VIPnet launched LTE commercially in March 2012 and currently we provide LTE in four major cities, making up almost 50 per cent of the country’s population coverage. The fact that we have widely available dual-carrier 3G on 2100 MHz for several years, offering speeds up to 42MBps, makes LTE a logical next step technology but it’s not a quantum leap.

What are the key techniques for network optimisation in LTE and what effect can it have on the customer experience?

Despite moderate LTE coverage our top customers with state-of-the-art smartphones should benefit from it whenever possible. In terms of network optimisation, in particular VIPnet has recognised the importance of smooth handovers between 3G and 4G networks in idle as well as in dedicated mode. LTE brings an additional challenge on 800MHz because there is no 3G layer, which makes handover from 2G to 4G and vice versa, even more interesting for operators to solve.

Why do you think that cloud services are now so important for telcos?

The cloud is really being hyped right now by operators as it is a good story to cover the real issues. Cloud is all about reducing costs by merging a number of utilities into one cost-efficient environment that delivers a secure and reliable service, and it is something that operators can offer to their customers. A few years ago it was called hosting, but now it has evolved. Cloud is a major opportunity for operators to avoid simply becoming bit-pipes.

Do you believe that RCS services can genuinely help the industry compete with OTT?

OTT players are gaining ground but for the huge majority of customers we are still “service providers”, and adopting RCS services is the next step in the evolution of telcos. Giving customers new ways of communication, in combination with good marketing will lead to a success story. The biggest issue with RCS is that is taking a long time to get to market and is in danger of dying before it starts, but maybe it still has a chance.

Is VoLTE part of your plans and what benefits will it bring both to operators and consumers?

Since we are the premium operator in the Croatian market, our promise to customers is to support all features they might need. As far as VoLTE is concerned we have been providing our customers with an HD Voice service for over two years. However, in conjunction with the development of handsets that support it we will implement VoLTE. We have to be very careful with the customer perception of VoLTE because they must find some significant value in it in order to accept it. It is very unlikely that VoLTE will find its way to the market merely because it is a new technology.

Should operators charge a premium for LTE just because it’s a faster service?

Investment in LTE requires that significant resources so therefore it’s expected that a premium charge should be applied. However, LTE should not only be faster but, according to standards, offer a quality level that guaranteed to be better than 3G.

What do you think will be the most exciting new development in LTE in 2013?

There are several technologies that will shape LTE in near future and one of them is heterogeneous networks. With higher bandwidth we can expect an even higher signalling load on the network, which is challenging to handle and control. The other will be controlling roaming pricing. Since Croatia is a very tourist oriented country, and will very soon become a full member of EU, it is our obligation to fully apply all the regulations regarding roaming pricing.
