Technical and pricing study on private mobile radio and trunked radio systems in Singapore

Plum and Aegis advised the IDA on technical, pricing and other assignment approaches for addressing congestion issues in the 400 MHz and 800 MHz bands used to deploy trunked radio systems (TRS) and private mobile radio (PMR) networks in Singapore.

The study examined the likely development of standards and availability of equipment for PMR and TRS and the potential to increase spectrum efficiency by deploying narrower bandwidth equipment. International benchmarking of licensing approaches and pricing was undertaken to inform on best practice in other countries, especially those with congestion problems.

The study included cross-border co-existence analysis and proposed coordination parameters for discussions with neighbouring countries. A new fee structure that would incentivise more efficient spectrum use was also developed. The outcome of the study was a proposed implementation roadmap for the IDA.
