The project addresses the difficulties of carrying VoIP (Voice over IP) traffic over shared satellite services (especially DVB-RCS) and will result in a commercially saleable device which allows telecom operators to deploy a range of satellite-based commercial services.
The key issues are expected to be:
The ability to use optimised VoIP over DVB-RCS will give long distance telecom operators many new opportunities. The lower cost of infrastructure and space segment is likely to be particularly appealing to less developed countries where telecom provision is still sparse.
The project is divided into 2 phases:
Phase 1 of the project was successfully completed. This involved the creation of a real and an emulated VoIP over DVB-RCS network. Tests were carried out over these networks to benchmark performance and to indicate whether any improvements were required to WTL's NOP (Network Optimisation Protocol - a proprietary method of reducing the IP bandwidth consumed by VoIP calls). The test report has been published and the conclusions indicate a package of modifications for NOP that will improve voice quality over DVB-RCS links. The BDR meeting took place in May 2006 and formal End of Phase 1 occurred in September 2006.
