Du, senior director of wireless broadband: “LTE will enrich the user experience”

Dr. Ayman ElNashar is senior director of wireless broadband and site sharing, for du, in the UAE.

Dr. Ayman ElNashar is senior director of wireless broadband and site sharing, for du, in the UAE. Ahead of the LTE World Summit, taking place on the 23-24 May 2012 CCIB, Barcelona, Spain we collect the thoughts of Dr ElNashar on the state of LTE and the issues surrounding it.

What are the main challenges you have faced, or expect to face, as you roll out LTE?

We are deploying LTE in In-Building Solutions (IBS) sites and are also focusing on securing backhauling capacity to cater for LTE peak throughput.

To what extent can LTE provide an insurance against declining revenue streams from voice and SMS?

I believe LTE will enrich the user experience and will compensate operators for declining revenue from voice and SMS by offering rich multimedia services and offering additional applications.

Is there a place moving forward for unlimited data tariffs? Are they sustainable?

Eventually VoLTE will be implemented but in a smart manner that efficiently utilises resources and QoS to improve the user experience.

With so much attention paid to the radio access network is there enough focus on backhaul?

In our case I think there is.  We should focus on exploring other non-traditional backhauling approaches such as PTP, GE Eband and PTP links among others.

What’s your view on FDD vs TD-LTE spectrum?

FDD is the best choice for mobile operators with 2G/3G networks, while TD-LTE can be considered as an evolution for ISPs with WiMAX/WLL networks.

Is there enough innovation occurring in the mobile network industry? Can you provide some examples?

Yes there are many evolutions in data, applications, and even legacy voice services like HD Voice. Also, on the network side, LTE will be evolved up to 1Gbps. There’s also the introduction of Single RAN, RAN with cloud concept, and femto/small cells.

What changes would you hope to see in the industry in the next five years?

We hope to see LTE evolved to 1Gbps and we need to see IMS as a common platform for all services.

Why are you attending the LTE World Summit and what are you looking forward to most?

To be involved in the state-of-the-art technologies that will be demonstrated at the conference

    I worry about the ability of many operators to leverage LTE in a way that really does raise their value.

    Your interviewee says he “believe[s] LTE will enrich the user experience and will compensate operators for declining revenue from voice and SMS by offering rich multimedia services and offering additional applications.”

    We heard the same during 3G roll-outs. Yes, a fatter pipe will deliver richer services – but whose richer services? The operator’s or those from the OTT players. If it’s the latter – where’s the value (outside of an ability to increase tariffs by a few percentage points)? It’s certainly not going to deliver an ‘experience’ that fosters loyalty to the operator.
