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

The main developments this past year have been the operators launching their LTE projects as well as LTE roaming projects. A major development was the establishing of Diameter Routing Agents (DRA) to enhance interoperability, enable global roaming coverage and to greatly improve network security.

What are the chief technical challenges you are facing?

The main challenges are to ensure DRA is correctly implemented, dealing with Circuit Switched fall-back issues and to enable operators to connect to an LTE signalling partner (such as Telenor Global Services).

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

In our experience it is important to measure the QoS experience in order to improve the customer experience of downloading, uploading and using new LTE handsets.

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

RCS will bring great opportunities since it will bridge the gaps between the islands of different OTT applications. It is also important that operators put great effort into launching RCS globally on new smartphones and handsets.

Pricing for LTE is a controversial subject. Are operators getting it right?

This is a challenging area with operators competing with each other locally and also for roaming pricing. In European countries pricing is driven by the EU regulation but outside EU it is up to the operators to agree on pricing that is affordable for customers.

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

For me it will be operators launching global roaming LTE data services.

What impact does LTE have on your backhaul strategy and technology choices?

It requires greater planning in terms of security, diameter routing and GTP2 (Global Tunnelling Protocol data traffic version 2) traffic, capacity and QoS.

The LTE World Summit, the premier 4G event for the telecoms industry, is taking place on the 24th-26th June 2013, at the Amsterdam RAI, Netherlands. Click here to download a flyer for the event.
