A major question facing the cellular industry, whether 2G or 3G, is how to grow mobile data services into valuable revenue streams. Talk of killer applications and the unbeatable combination of the internet and mobility has faded. Nevertheless, looking around the world, we find that new and innovative services are being introduced. Success seems to come with careful market segmentation – recognising that different services appeal to different groups of customers.

Ensuring that the network can support these new services and the growth in voice traffic is a challenge too, requiring network enhancements, optimization of existing facilities and, for some, migration to new technologies and new spectrum. At the same time research and development on the next generation of technologies continues.

Our consultants have:

• Reviewed network design and capacity planning methodologies for WCDMA operators
• Advised the Radiocommunications Agency on appropriate methodologies for the determination of spectrum requirements for forthcoming 4G mobile systems
• Undertaken feasibility analysis of the implementation of a GSM-R system
• Advised the Telecommunications Regulatory Commission of Sri Lanka on the assignment of GSM 1800 spectrum
• Supported operators in bids for GSM and 3G licences
• Developed algorithms and functionality for cellular radio network planning tools
