We are investigating how to provide satellite access for individuals and communities where broadband services are currently not available. Research combines new access technologies, such as Ka-band transmission, adaptive coding and modulation to increase access speed, coupled with novel cross-layer methods to enhance the QoS for voice, data and video services, to realise a multi-service network.

Another activity is exploring networking technologies for environmental monitoring; this includes techniques for low-cost data upload (often polled), background collection of large data sets, occasional access to high rate upload (e.g. in response to external stimulus), a need to work from battery (energy-conserving methods), scalability to a large installed base, and a need for resilience (multiple communication paths).

New architectures and technologies include low-cost random access and delay-insensitive transport.
