Abdus Samad, Assistant Manager, Radio Network Design and Performance, for Augere Wireless Broadband/Qubee, is taking part in the Operator Mindshare taking place on Day Two of the LTE Asia conference, on the 23-25 September, at the Marina Bay Sands, Singapore. Here we found out more about the strategy around the transition from WiMAX to LTE.
What is your mission and what are the main challenges you are facing in delivering wireless broadband?
Our mission is to provide affordable broadband to all, so that they can experience the best of the Internet. We have been operating using WiMAX technology for more than five years and are currently in the planning stages for transition to TD-LTE. Our aim is to provide high-speed broadband service to end users no matter what technologies we are using.
Air interface management is always challenging, especially when the frequency band is above 2GHz. Then deep indoor seamless coverage becomes one of the major challenges. Other than that, end user demand for high volume content has increased significantly in last few years. With limited wireless resources, capacity management is a vital point for us. Development of LTE is now real and there are numerous live networks around the world, we expect we will be able to meet the user demand with LTE deployment.
How has the TD-LTE eco-system progressed over the last 12 months and what are your expectations for the next couple of years?
Development of the TD-LTE eco-system is now advancing very fast. The main focus will be on the terminal prices. China and India are playing an important role in reducing the terminal price level. We are now attending seminars and forums to understand the global market demand. Our expectation is that terminal prices will go down very fast within the next year. We also expect major features like carrier aggregation, CoMP, load balancing and HetNets to mature soon for efficient radio resource management.
Is your use of TD-LTE based on a technical merit or due to the availability of its spectrum?
Most of the vendors have already commenced their product EOM (End of marketing) for WiMAX so the decision is based on the fact that the ecosystem and existing technology development.
What are the key antenna technologies that will make an impact over the next couple of years?
Dual Layer beamforming, smart antennas with RET and the inclusion of more arrays to improve the diversity will significantly improve the user experience.
What is the key aspect of the LTE Asia conference you are most looking forward to?
Our main focus would be on the eco-system development and learning from the real-time experiences of the operators who are already running LTE services.
