LG U+ believes South Korea’s market leading network status derives from the cutting-edge handsets present in the market. In this interview he details the plans for bringing further enhancements and speeds to the network over the next couple of years. To hear more about LGU+’s strategy you can hear Sun Tae Kim, EVP/Director of SD, LG U+, speak on Day Two of the 9th annual LTE Asia conference taking place on the 23rd-25th September 2014 at the Marina Bay Sands, Singapore. 

Operators in South Korea seem more willing and able to invest in next-gen technologies earlier than many Western operators? Why do you think this is so?

South Korea has the world-leading manufacturers of smart devices – such as Samsung and LG – and implemented nationwide LTE network sporting the best quality and functionality. But mobile subscribers have been already saturated. The Korean operators, SKT, KT, and LGU+, could not survive in the market just with existing technology and can only beat the competition with new technologies and services. As a result, South Korea has become the world test-bed for next generation technologies.

Following on from that would you say South Korean customers are more willing to try, and pay for, new mobile services?

LTE World Summit 2014 – Day One Round-Up

Once again the LTE World Summit returned to the sunny streets on Amsterdam, or at least to the interior of the RAI exhibition centre, which is nearly as good. This time up on stage a live Twitter feed was visible behind the speakers, providing an opportunity for those in the audience to get their Tweet up on the big screen in real-time – always a thrill.

Proceedings were kicked off by Erik Hoving, CTO of KPN. Hoving reiterated a theme that he has expressed before from this platform – that operators need to move away from specifications and become more people centric.

“We need to figure out the role of the smartphone,” he said. “The future isn’t about LTE or 5G, it’s about users. If we don’t understand users, we don’t have a role to play. We need to move to a user centric world.”

Want to find out more about what comes after 4G? Paul Ceely, head of network strategy at EE is speaking on the subject of evolving beyond LTE on Day One of the 10th annual LTE World Summit, the premier 4G event for the telecoms industry, taking place on the 23rd-26th June 2014, at the Amsterdam RAI, Netherlands. In this interview we find out his views on the impact new technology such as NFV will make and how the carrier plans to maintain its 4G leadership.

Do you feel any pressure for EE to be leaders in terms of network technology?

Our ambition and vision is to build the best network and best service so our customers trust us with their digital lives.  And to this end we see network technology and more specifically LTE and LTE-A as a way to maintain network leadership.  Technology is evolving increasingly quickly, both on the user device side and the network, and so to maintain network leadership we must maintain technology leadership.

Interview: SVP & Head of Network Technology, R&D Center, SK Telecom: “SK Telecom believes that NFV technology will become a key enabler in its mid-to-long term network structure innovation.”

In this interview ahead of the LTE World Summit, Park Jin-Hyo, SVP & Head of Network Technology at the R&D Center, SK Telecom, tells us how the Korean operator is taking a lead on virtualization and gives us a glimpse of what benefits a fully-fledged VoLTE and LTE Advanced network can bring end-users.

Do you feel any pressure for SK Telecom to be leaders in the network technology space?

With the world’s first commercialization of CDMA, multi-carrier, VoLTE, and LTE-Advanced, SK Telecom has been a pioneer in developing mobile network technologies. Rather than pressure, we feel pride for pursuing the best customer experience through providing leading and differentiated technologies.

To what extent have you virtualised your network and how important will NFV be in the future?

Our ultimate goal is to virtualize all telecommunications equipment in implementing software. However, considering the possible impact on the existing network, in 2014 we plan to start with IMS, telecommunications infrastructure to provide HD Voice, as it is based on a general-purpose hardware server and therefore easier to apply virtualization technology.

After validating performance and stability of IT virtualization, we will continue to virtualize other network equipment as well. Going beyond virtualization of core network functions, we plan to apply the technology on base stations, the access point with customer, eventually aiming to innovate the whole structure of telecommunications infrastructure.

By applying NFV technology, a MNO can efficiently cope with ever-increasing data traffic by securing flexible network structure, apply new services at an incomparably faster pace and, as hardware and software will be separated also provide more business opportunities to SMEs. As such, SK Telecom believes that NFV technology will become a key enabler in its mid-to-long term network structure innovation.

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?

Where next for LTE?

Keith Dyer is Editor of The Mobile Network

For understandable reasons, most attention regarding LTE progression tends to focus on the sort of technical features that will boost capacities and decrease latencies across the network. I’m thinking of those items that are about enabling Carrier Aggregation, interference cancellation, HetNet co-ordination, increased antenna arrays and so on.

But LTE as a technology is also travelling in another direction. If the “more features enabling more bandwidth” path represents a vertical deepening of LTE’s capabilities, you might call this other direction a horizontal expansion. That is because this direction of travel sees LTE radio technology being used for something other than increased cellular capacities, but instead utilises (in the proper meaning of that word) LTE for a wider range of applications. Although these may be niche use cases, I think they are interesting to keep an eye on for three main reasons.

Roman Lapszow, Senior Project Manager, Technical Strategy, Radio Networks and Microwaves, Orange Group is speaking on Day Two of the LTE MENA conference, taking place on the 11th-13th May 2014 at the at the Conrad, Dubai, UAE. Ahead of the show we speak to him about where the Orange network is heading in 2014 and where the focus is for upcoming developments.

How much impact will LTE-Advanced have on Orange’s networks in 2014?

The launch of LTE networks has brought a significant growth of data traffic and consumer interest. LTE is driving evolution in our networks and there is no doubt of the value of LTE. The only remaining question in markets where we have yet to launch is when and in what bands. As LTE-A is concerned, the majority of our efforts are focused on studies, evaluations and deployment of LTE-A. The major drivers for 2014 are carrier aggregation, the flagship feature of LTE-A, and to a lower extent coordinated multipoint processing (CoMP).
